OUTLOOK anywhere error RPC_S_server_Unavailiable (0x6ba)
My setup is exchange 2007 on server 2003
Remote clients cannot setup OUTLOOK anywhere session. They get a message about the Exchange server being unavailable when they configure outlook anywhere.
If I run the exchange connectivity tool it passes autodiscover test but fails the RPC/HTTP test at the last step with message RPC_S_server_unavailable (ox6ba) on port 6004. There is lots of information about this error and server2008/IPv6 but I am using server2003 IPv4.
Can anyone give me some pointers on how to fix this one.
