Verifying support for RPC over HTTP Proxy<\/p>\n\n\n\n

The changes in this article assume that you have configured a functioning RPC over HTTP Proxy server. To verify that you have enabled support for RPC over HTTP on a server running Windows Server 2003, follow these steps:<\/p>\n\n\n\n

1.       In Control Panel, click Add\/Remove Programs<\/strong><\/p>\n\n\n\n

2.       Click Add\/Remove Windows Components<\/p>\n\n\n\n

          This will start the Windows Components Wizard<\/p>\n\n\n\n

3.       Click Networking Services<\/strong>, and then click Details<\/p>\n\n\n\n

4.       Ensure that the RPC over HTTP Proxy<\/strong> check box is selected.<\/p>\n\n\n\n

Adjusting the TCP\/IP MaxUserPort<\/strong> and TCP TimedWaitDelay<\/strong> Parameters<\/p>\n\n\n\n

By default, when a program requests any available user port from the system, a port is allocated between ports 1024 to 5000. With the default setting, a RPC over HTTP Proxy server will support less than 4000 connections. You will need to set the TCP\/IP MaxUserPort<\/strong> parameter to its maximum setting of 65534 in order to support approximately 30,000 RPC over HTTP connections.  The TCP\/IP TcpTimedWaitDelay<\/strong> value determines the length of time that a connection stays in the TIME_WAIT state before it is closed. By default this is set to 4 minutes. It is recommended that this be set to 60 seconds for an RPC over HTTP Proxy server.<\/p>\n\n\n\n

To add and configure the MaxUserPort<\/strong> parameter:<\/p>\n\n\n\n

1.       Start Registry Editor (Regedt32.exe).<\/p>\n\n\n\n

2.       Locate the following key in the registry:<\/p>\n\n\n\n

          HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters<\/p>\n\n\n\n

3.    Right-click on Parameters<\/strong> and select New DWORD Value<\/strong>. Type MaxUserPort<\/strong> in the     Name data<\/strong> box, type 65534<\/strong> (Decimal) in the Value data<\/strong> box, and then click OK<\/strong>.<\/p>\n\n\n\n

NOTE:<\/strong> The default setting for the MaxUserPort<\/strong> value is 5000<\/strong> (Decimal).<\/p>\n\n\n\n

To add and configure the TcpTimedWaitDelay<\/strong> parameter:<\/p>\n\n\n\n

1.       Start Registry Editor (Regedt32.exe).<\/p>\n\n\n\n

2.       Locate the following key in the registry:<\/p>\n\n\n\n

          HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters<\/p>\n\n\n\n

3.     Right-click on Parameters<\/strong> and select New DWORD Value<\/strong>. Type TcpTimedWaitDelay<\/strong> in the Name data<\/strong> box, type 60<\/strong> (Decimal) in the Value data box, and then click OK<\/strong>.<\/p>\n\n\n\n

NOTE:<\/strong> The default setting for the TcpTimedWaitDelay<\/strong> value is 240<\/strong> (Decimal), which equals four minutes. Never set this value below 30<\/strong>. <\/p>\n\n\n\n

Quit Registry Editor and restart the system<\/strong>.<\/p>\n\n\n\n
