『 闲 情 茶 聊 居 』

PCAnywhere by Symantec (Symantec) Company produced the remote control software, which features a powerful, almost all network connections and network protocols, the use of PCAnywhere, computer managers can easily achieve the local computer to control the computer remotely, The computer makes the two places can work together. In the remote control at the same time, PCAnywhere also have better security policies and mechanisms to verify the password, thus ensuring the long-range charged with the security of the host.

PCAnywhere can be run on Windows 98/NT/2000/XP platform, although it is a commercial software, but we can use it for free trial versions of the trial period of 30 days in general, there is no functional limitations. This article based on PCAnywhere 10.5.

1. PCAnywhere working principle

Prior to the implementation of the remote control must be installed on both computers PCAnywhere, one of which must be configured to Pikong Duan, another configuration for the host. Pi Kongduan computer and wait for the host computer to connect, and Pi Kongduan controlled by the host. Control of the implementation process is as follows:

First Pikong Duan issued by the host to share control of the request, control termination received a request to share control of the future will give a response to the signal, and the host to verify legal status, at this time, the host must be Remote-controlled side to provide the necessary control of the legitimate user account and password, if the server to verify correct account number and password, you can begin to manipulate the control terminal server for remote control, or refuse to control the server-side control of the request. In addition to the Pi Kongduan authentication with the means to ensure safety, but also to control who can connect the computer and the remote users have the authority.

2. Pi Kongduan configuration

Start PCAnywhere, in PCAnywhere Manager window, as shown in Figure 1, click the "Pi Kongduan" button, the system will be controlled by-side display that can be used to connect projects, including Direct, Modem, Network, Cable, DSL, and other options ,, Direct refers to the adoption of a direct serial cable connected, in general rarely used; Modem is the dial-up access through a modem and Internet connection; Network is the network card through the visit, which tends to be used in local area networks in remote control, Cable is Cable Modem (cable modem), DSL, including our common ADSL. We can connect the network to choose the actual situation, double-click on the appropriate option to start Pikong Duan. If you want to modify the properties of the project have, in selected items, click the right mouse button, select "Properties" command to configure.


If you want to custom configure the computer Beikong Duan, double-click "Add Pi Kongduan" icon appears in the Pi Kongduan Properties dialog box, "linking information" tab in the "equipment list" to select long-distance Connected device, usually select TCP / IP option agreement, if it is in the local area network for remote control, can choose to SPX, NetBIOS option agreement.

Click the "caller" tab, click "new item" button, the emergence of new users of the "new caller" dialog box, first of all, "authentication" tab to set up good name and password, and then single - Hit the "authority" tab, set up to give the user rights, click "OK" button to return to the "caller" tab, the caller can see the list of the list to add new users.

Click "OK" button to complete a new set Beikong Duan, double-click the icon Beikong Duan, PCAnywhere can be reduced to the system tray icon area, and wait for the host computer to connect to control.

3. Host configuration

In PCAnywhere Manager window click the "host" button, and then double-click "Add host" icon in the "host of new properties" dialog box choose "to connect information" tab, select the "TCP / IP" option here and set up a similar Beikong Duan, if local area network can also choose SPX, NetBIOS agreement.

Click "Settings" tab, "Pi Kongduan control of the network PC or IP address" box, fill in the Pi Kongduan IP address, if it is in the local area network can not set up because the host from the network Open to all in search of Pi Kongduan computer. If you want to automatically log host of options "to connect automatically log on to the Pi Kongduan" option, and then fill in the login name and password.

Finally, the "Properties" dialog box, click "OK" button to return to the Manager window, double-click the new icon of the host, you can begin to connect the remote.

4. Remote control computer

Pi Kongduan in connection with the success of the host, will be shown in Figure 2 of the window, Pi Kongduan desktop will appear in the window with a mouse click in the desktop window, this time as they can use the same local computer Remote control of the computer.


Through the window of the upper button, you can also file transfer, voice dialogue, screen capture, such as Pi Kongduan resumption of operations. This is at the Pi Kongduan unattended, in order to protect the safety of Pi Kongduan connection, you can also click in the window "on-line option" button, and in the dialog box that appears choose " Keyboard-controlled side locked, "Pi Kongduan option to disable the computer's keyboard and mouse, also have the option to" Pi Kongduan black screen "option, so you can stop the operation of other people to see.

If you want to stop the operation of remote control may be at the top of the window, click the "end of the conversation" to the end of the control button.

5. Optimization of network connection

In order to connect the network more secure, reliable, fast speed, we can optimize the allocation of long-distance connections.

In PCAnywhere Manager window click "Tools → Performance Optimization Wizard" menu command, open the "Performance Optimization Wizard" dialog box, click "Next" button, that is, there will be "ColorScale" dialog box, in which the "choice of control End-level color display "list, select an appropriate color, the color of choice may be based on network connection speed to determine, but the color effect of the low may be worse is if the choice of broadband users or 16M colors, but also conducive to the long-range computer To carry out the operation. In the next "simultaneous resolution" in the dialog box to select "Pi Kongduan narrow the desktop to match the regional host" option in the "Desktop Optimization" dialog box, select "Pi Kongduan disable the Active Desktop" and " Control end desktop optimization, "This will further improve the speed of remote control session. Click to continue the "next step" until the end "to complete" optimization settings.

PCAnywhere can support multiple remote computer control, and there are more stringent user authentication mechanism, use it to remotely control a relatively simple set, a high success rate, safety, and thus a very wide range of applications.

"Open Desktop" My Computer "shortcut icon, open the main interface in order to open the" Tools → Folder Options ", in the open dialog box, click the" View "tab, remove" the use of simple Sharing (Recommended) "check. And then open the" Control Panel ", double-click" user account "option to create a user with a password. Right-click the mouse to the need to share the folder, click Right-click menu of "sharing and security" option, click "Sharing" tab, click the "Share this folder" option, click the "authority" button in the "competence" box set election In everyone ", click" delete "button to delete it. And then click "Add" button, select just set up the account password, click "OK" button. When such a local area network users would like to see the shared folder, only enter the correct user name and password to enter. ""
  In accordance with the above-mentioned method, the Local Area Network tips shared file access do not have access, how to be operating?

No permission to visit al solutions:
1. To set the local administrator account's password.
2. Settings for the classic model of network access mode.
3. Settings to allow network access from the computer user account (Guest joined the group).
4. Prohibited from setting network access computer user account (Guest deleted).

Set:
Start -> run gpedit.msc--> Computer Configuration -> windows settings -> Security Settings (Security Settings) -> Local Policies (Local Policies)

1.: The right to assign the user (User Rights Assignment) -> Access this computer from the network (Access this computer from the network) -> add the Guest group.
2.: The right to assign the user (User Rights Assignment) -> from the network to refuse access to this computer (Deny access to this computer from the network) -> delete the Guest group.
3.: Security options (Security Options) -> Network access: the local accounts Sharing and security model (Network access: Sharing and security model for local accounts) -> change to the classic mode.


If you are completely in accordance with the above methods do not trip, run REGEDIT, to:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Lsa on this Zijian of restrictanonymous value set to 0 on the line.
To: restrictanonymoussam the value 0 into it.
The following is a description:
1, RestrictAnonymous registered in the control of any user access to information on local-level settings, if RestrictAnonymous is set to 0 (default), any user can access the network through local information, including user name, detailed account of the strategy And share name. This information can be attackers in the attack when the use of the computer. Through these information, the attacker is likely that the current computer system administrator account, sharing the path of the network as well as strong passwords. This revised level of security as follows: Run Regedit.exe to edit the registry, locate Zijian HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Lsa on the value of this Zijian restrictanonymous from unsafe 0 value was revised to a number of high-level security Value of 1 or 2. NOTE: If you raise the security level, then this may cause a computer in the LAN to access can not be.
2, when disabled TIP / IP option in the High Wins in NetBios set, was unable to visit the local area network.
3, if the Sasser virus will not be able to visit the local area network.
4, in the absence of IP will be set to a fixed IP, LAN function will be limited.

Keyword Index: xp set up local area network; xp shared local area network; xp local area network connection; xp shared local area network settings; xp how to set local area network; xp can not access the local area network; xp local area network visits


Tight for reference.
 

Many people believe that and I have the same experience, WIN XP network setup and all the WIN 2000 posed exactly the same, but there have been no visits, I think mainly because of XP's security settings and 2000 Not the same result. I address this issue in a number of online information and a variety of on-line to provide a common solution to the appropriate testing done and now introduced to collate all the hope that it can face the problem of online help, and please continue to master Point. Some of the content from the network, please do not forgive them one by one reference.

First of all, here is not to consider the physical connection and other issues, and talk about strategy. In addition, the agreement to install and set up the correct IP address of the computer at the same time try to set up a working group within the same network segment and the IP address.

Secondly, the on-line for the problems described in more references here are no longer tired. When sharing and access problems, please consider the following steps:

1. Guest check whether or not to open account

By default, XP does not open the guest account, so some other people in order to be able to browse your computer, enable guest account. At the same time, in order to set up security for guest password, or the appropriate authority. Of course, for each machine set up a user name and password to access the computer between each other.

2. Guest refused to check whether the user from the local network access

When you open a guest account but still can not visit, check whether the refusal to set up network access from the guest computer, because XP is not allowed to default from the guest registry network, so even if the guest to open the same can not visit. In the Guest user opens the system of the lifting of restrictions on the Guest account, click "Start → Run," "Run" dialog box, type "GPEDIT.MSC", open the Group Policy Editor, select the "Computer Configuration → Windows → set the security settings of the local strategy → → User Rights Assignment ", double-click" from the network to refuse access to this computer "strategy, which deleted the" GUEST "account. So other users can use the Guest account network access through the use of Windows XP system, the computer.

3. To network access mode

XP default is to log on from the network to all users of all guests, according to the accounts of the deal, so even if the network administrator from the registry only with permission of the guests, when the visit can not be the case, try to change the mode of access networks. Open the Group Policy Editor, select the "computer configuration settings → → Windows security settings of the local strategy → Options → security", double-click "Network access: the local account Sharing and security model" strategy, will be the default setting of "guests only -- Guests to the local user authentication, "changed to" Classic: local users to verify their identity. "

Even if this does not open the guest, you can also enter the local account and password to log in to access your computer, local account and password to access your computer has the account and password. If the need to access the network account and password, you can enter to access the computer has the password and account to log on.

Does not change the mode of access, you may not even enter a user name and password can be done, / / computername / guest for the gray is not available. Even if the password is empty, do not open the guest, you can not log on to determine points. Into the classic mode, the minimum can be achieved in 2000 as the guest account did not open the case, can enter a user name and password to log into your computer. Perhaps you will encounter a special situation, look at the next.

4. A note of caution

We may encounter another problem, that is, when the user's password is empty, even if you do all of these changes could not log in, visit or will be rejected. This is because the system in the "safe option" in "account: Use local blank password account only for the console log," is the default strategy of opening, according to the Windows XP security policy in refusing to give priority to the principle, the password is empty Users to access the network using the Windows XP computer will be prohibited. As long as we can out of this strategy to solve the problem. In the security options, to find "a blank password to use the account only for the local console login", you can disable, or even to open a guest into the classic mode and still can not log on. After more than a basic change can be visited, you can try a selection for you. Add the following points may be other problems.

5. Neighbors can not see the network computer

The network may not always see your neighbors want to access the computer, unless you know the name of the computer or IP address, or search through the direct input / / computername or / / IP. By the following operation to solve: Start of "computer browser". "Computer browser service" on the network to maintain an updated list of computers, and will be made available to the list of designated as the browser of your computer. If you stop this service, neither update nor the maintenance of the list.

137/UDP--NetBIOS name servers, network basic input / output system (NetBIOS) name server (NBNS) agreement is the TCP / IP on the NetBIOS (NetBT) protocol suite, based on its NetBIOS name of the access network to provide host Name and address of the mapping method.

138/UDP--NetBIOS reported data, NetBIOS datagram is a TCP / IP on the NetBIOS (NetBT) agreement as part of the family, which used to log on and browse the network.

139/TCP--NetBIOS conversation service, NetBIOS session service is a TCP / IP on the NetBIOS (NetBT) protocol suite, for its Server Message Block (SMB), file sharing and printing. Please set up a firewall to open the port. As long as the general in the firewall to allow in the folder and printer sharing it.

6. On the sharing model

Sharing of the default XP only guest to give permission to allow users to change or choose the "My Documents." Windows 2000 operating system users to set up a shared folder attributes are very simple to operate, just use the mouse right-click the folder and choose Properties, you can see the label set up to share. In Windows XP System Settings folder is shared when more complex, users can not see through the operation of the above-sharing settings tab. Specific changes are as follows: open "My Computer" in the "Tools" select "folder attributes," out "View" tab in the "Advanced Settings" section, scroll to the bottom of the "simple file sharing (Recommended ) "In front of the abolition of choice, and if there are options column" Mickey Mouse "of their choice will also be canceled. This revised user will be able to use as Windows 2000 on the same folder attributes to facilitate the revision.

7. On the network with neighbors to visit or do not respond to the problem of slow response

In Win2000 and WinXP neighbors in the online system when the 30-second delay will default, Windows will use this time to search the remote computer if there are plans to designate the task (or even to the Internet in search). If the search network would not respond to a restriction of waiting, then more than 10 minutes of delay on the error and even surprising. The following is a specific solution.

A. plans to switch off the task of WinXP Service (Task Scheduler)

Go to "Control Panel / Administrative Tools / Services" open "Task Scheduler" of the Properties dialog box, click the "stop" button to stop the service, and then start as the type of "manual", so that the next start-up Will not automatically start the service.

B. delete the registry key in the two sub -

To the primary key in the registry to find "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerRemoteComputerNameSpace"

To delete the following two Zijian: and.

Of these, the first on-line neighbors Zijian decision whether or not to search on-line printer (or even to go to the Internet in search), if the network does not share the printer will be able to delete the key. The second is Zijian decide on the need for finding mission designated by the plan, which is on-line neighbors is the chief culprit behind, and must be deleted Zijian.

Summary

Can not access mainly due to the default XP does not open the guest, even if the opening guest, XP default is not allowed to access the network from the guest computer. It should be noted that there is the problem. Some believe that not a safe place or give the company a computer system to do the password is empty, but that the registry is not allowed. As long tried more than I believe is no longer a problem
