I'm running SBS 2003 with Exchange SP2
After configuring the Outlook client for RPC/HTTP I cannot logon, it used to work and something broke.
I ran testexchangeconnectivity.c
om test and this is what I'm getting

The only thing I tried was to remove RPC component rest IIS and add it back. Didn't make any difference.
what else should I check?
