How to Configure pcAnywhere Behind a Proxy Server (254367)

MORE INFORMATION

To configure pcAnywhere on a client computer behind Proxy Server:

1. Install the Microsoft Winsock Proxy client on the internal client (Microsoft Windows NT, Microsoft Windows 95, or Microsoft Windows 98) that will be the pcAnywhere 8.0 host (if not already done). You can do this by connecting to \\servername\Msplnt and running the Setup.exe program from this folder.
2. Be sure that the Winsock Proxy client is properly installed by using the Chkwsp32 utility from the client computer. You may also want to test the Winsock Proxy client by using a Winsock program, such as File Transfer Protocol (FTP), from a command prompt to ensure that the Winsock Proxy client is configured properly.
3. Create a Wspcfg.ini file and save it in the folder where the Awhost32.exe file is installed (by default this is in the Program Files\PcAnywhere folder). The contents of this file depend on the client operating system and the Proxy Server configuration. If either of the following conditions exist:
   
   
   • Windows 98 is the client or host operating system for pcAnywhere

     -or-

   • Microsoft Windows NT is the client or host operating system and Access Control is disabled for Winsock Proxy on the Proxy Server
   use the following Wspcfg.ini file to bind pcAnywhere to an IP address on the Proxy Server's external interface:

   [awhost32]
      ProxyBindIp=5631:<1st IP address>
      ServerBindTCPPorts=5631
      LocalBindTCPPorts=65301
      KillOldSession=1
      Persistent=1
   						

   If the client or host computer is using Windows NT and Access Control is enabled for Winsock Proxy on the Proxy Server, use the following Wspcfg.ini file:

   [awhost32]
      ProxyBindIp=5631:<1st IP address>
      ServerBindTCPPorts=5631
      LocalBindTCPPorts=65301
      KillOldSession=1
      Persistent=1
      ForceCredentials=1
   						

   NOTE: Verify that the Wspcfg.ini file is saved without the .txt file name extension.

If the client or host computer is using Windows NT and Access Control is enabled for Winsock Proxy on the Proxy Server, the following additional steps are required:

1. On the Proxy Server, create two protocol definitions:

   Protocol Name: PcAnywhere-UDP
   Initial Connection:
     Port=5632
     Type=UDP
     Direction=Inbound
   Port Ranges for subsequent connections:
     Port=1025-5000
     Type=TCP
     Direction=Outbound
   
   Protocol Name: PcAnywhere-TCP
   Initial Connection:
     Port=5631
     Type=TCP
     Direction=Inbound
   Port Ranges for subsequent connections:
     Port=1025-5000
     Type=TCP
     Direction=Outbound
   					

2. Run the Credtool.exe program on the client computer to provide credentials for the Awhost32.exe program. From the client computer, open a command prompt and change folders to the Program Files\Pcanywhere folder, and then run the following command:

   credtool -w -n awhost32 usernamedomainpassword

3. Configure pcAnywhere so that it does not run as a service. To do this:
   1. Right-click the pcAnywhere icon on the host computer, such as Network or Direct, and then click Properties.
   2. On the Settings tab, click to clear the Run As a Service check box in the "Host Startup" section.
   
   WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
   
   
   
4. On the host with pcAnywhere versions 8.0 or higher installed, add the following entry to the registry:

   HKEY_LOCAL_MACHINE\Software\Symantec\pcAnywhere\CurrentVersion\System

   Create a DWORD entry called TCPIPConnectIfUnknown with the value set to "1".
