Microsoft Windows troubleshooting checklist

1. Is your Windows operating system supported?
2. Are you installing and configuring the Microsoft Proxy Server on a Windows NT machine?

1. Is your Windows operating system supported?

   Check the Planning, Installing, and Configuring Host On-Demand guide for the most recent list of supported Windows operating systems.

2. Are you installing and configuring the Microsoft Proxy Server on a Windows NT machine?

   The following steps are based on Windows NT. Other Windows platforms, such as Windows 2000 Server, may require additional steps.

   Configuring the Proxy Server is a two-part process. You must first configure the server portion and then install the Proxy Server client code on the client workstations that will download the Host On-Demand client.

Configuring Proxy Server on the server machine

To configure the Proxy Server on your server machine, take the following steps:

1. Install the IIS Web server on your server machine. This is a prerequisite.
2. Take the following steps to display the Properties panel for the Winsock Proxy computer:
   
   1. Click Start > Programs > Microsoft Proxy Server > Internet Service Manager.
   2. The following default services should be listed in the Internet Service Manager panel. Note that a default service will not be listed if the administrator has turned it off.
      
      • Socks Proxy
      • Winsock Proxy
      • Web Proxy
      • WWW
      • Gopher
      • FTP
   3. Click the computer name in the Winsock Proxy line.
   4. Open the properties.
3. Take the following steps to add a Protocol Definition for each special port required by Host On-Demand.

   Note that https (443) and telnet (23) are already defined.

   1. Click the Protocol tab.
   2. Click Add.
   3. Enter a descriptive name such as 'HOD port 8999'.
   4. Enter the port number required by Host On-Demand, such as 8999.
   5. Enter a connection type of TCP. All Protocol Definitions for Host On-Demand will have TCP as the connection type.
   6. Enter a direction of Outbound. All Protocol Definitions for Host On-Demand will have a direction of Outbound.

4. Take the following steps to configure the users and machines that can access the ports that you have configured:
   1. Click the Permissions tab.
   2. The settings listed depend on how you, as the network administrator, use Windows in your own network environment. You should give all users access to port 8999 if you want them to be able to read configuration data from the Host On-Demand server.

Configuring Proxy Server on the client workstations

In addition to configuring the Host On-Demand ports on the Proxy Server, you must install the Proxy Server client code on the workstations that use Host On-Demand. This client code allows workstations to use Telnet type programs like Host On-Demand with the Proxy Server. Without this code installed, clients will be able to download and install the Host On-Demand client through port 80 but will not be able to log on to Host On-Demand. Without the code installed, users will receive a LOG001 error message.

To install the Proxy Server client code, take the following steps:

1. From a command prompt on the client, type net use * \\proxy_server_name\mspclnt, and then run setup from this network share to install the proxy client.
2. Confirm that the following TCP ports are configured:
   • 80 - HTTP Web traffic
   • 23 - the standard clear text Telnet port
   • 8999 - Host On-Demand user configuration data port
   These TCP ports are required in order for Host On-Demand clients to connect to the host machine successfully.
3. Configure any additional ports:
• 443 - the standard https port
• 12173 - the first Host On-Demand Redirector port configured by the Host On-Demand Redirector
4. Verify that the Proxy Server client code is installed by checking either of two places:
   • Start > Programs
   • Start > Settings > Control Panel > Add/Remove Programs
