SUMMARY
This article discusses how Microsoft Systems Management Server (SMS) 2003 clients communicate with an SMS 2003 management point through a router or proxy server that blocks or intercepts all traffic on port 80.



MORE INFORMATION
By default, the Systems Management Server (SMS) 2003 Advanced client executable (Ccmexec) uses Microsoft Windows HTTP Services (WinHttp) on port 80 to connect to an SMS 2003 Management point. However, SMS 2003 Service Pack 1 lets you change the default TCP port that the SMS Advanced Client uses to communicate with management points. If a router or a proxy server separate the SMS 2003 clients from the management point, you may have to take the following actions, as appropriate for your situation:  If the router or the proxy server blocks port 80, you can change the default port that Systems Management Server uses to communicate with SMS Advanced Clients. To change the default port, see the section titled &quot;Configuring the Advanced Client TCP Port&quot; in the Scenarios and Procedures for Microsoft Systems Management Server 2003: Security white paper.

 To communicate through a router by using the default port, you can open port 80 for the SMS 2003 client to communicate with the management point. To communicate through a proxy server that intercepts all network traffic on port 80, you may have to add the SMS 2003 management point server name to an access list. When you do this, the proxy server can forward the requests to the management point and not to the Internet.
