After upgrading to Cisco AnyConnect v2.3.0254 Outlook on the clients will not connect to the Exchange like before.
I can RDP and Ping det exchange server, but Outlook won't connect. Even more strange is that after 10-30 min's of "waiting" Outlook suddenly connects and everything works perfect for the rest of the VPN session.
I have noticed that pinging the exchange server right away after VPN connects don't get any replay, while pinging the VPN router itself does. If I wait for about 30 seconds and ping the exchange server again it replays. It might get sense for some of you...?
I have seen this before with checkpoint secure remote but it may work for you also as its more of an issue with rpc and vpn clients.
I implemented method 2 and it resolved the issue
let me know how it goes
The following registry key was not there, but I created it (along with the string Server2003NegotiateDisable), however no better result.
After that I did allow all traffic for a short period through the firewall with no better result.
I have run "outlook /rpcdiag" and see that no rpc prossess connects. So the problem is around rpc.
I'm getting short of idÃ©as here...
Also I still can't understand why pinging the server wan't respond before 30-60 sec of waiting after VPN connection is established (while pinging all other servers on the same net responds on first attempt).
suggest running tcpudmp or wireshark on client machine to see whats happening to the traffic.
post the output here if you want me to review
