RPC over HTTPS Connectivity Issue for one remote user only Exchange 2003/ Outlook 2007
Posted on 2008-10-06
We have 10 RPC over HTTPS users connecting to an Exchange 2003 SP2 server. One laptop user chose to upgrade to a better wireless service using an ATT cellular wireless card. His XP Sp2/Outlook 2007 worked fine before change.
Now he cannot connect remotely. I reconfigured his settings and tested his settings with my laptop (mine connected right away wirelessly).
I run an outlook /rpcdiag and it conntinually says CONNECTING for the different types of connections, but never connects. We replaced his wireless card. I disabled XP SP2 firewall. I uninstalled his Cisco VPN Client 5.0. I do not seem to see any relevent errors in his event log. Older McAfee AV is not blocking any traffic.
Any other suggestions on how to troubleshoot the error that seems to be on the specific laptop?
