We are having troubles with setting up Outlook Anywhere (RPC over http) on SBS 2003.<br />
Microsoft Remote Connectivity Analyzer reports an error when testing the NSPI-interface on Port 6004.<br />
When trying to connect on port 6004 directly from the exchange server/ rpc proxy (single server scenario) the connect failes. Port 6001 and 6002 are able to connect with telnet.<br />
The registry key ValidPorts under HKEY_LOCAL_MACHINE\Softwar<wbr />e\Microsof<wbr />t\Rpc\Rpcp<wbr />roxy are correct. Windows Firewall is disabled.<br />

What can be the reason for this issue?<br />

Outlook Anywhere fails with RPC-Endpoint 6004 error

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
