Initial connect of Outlook client to Exchange server 2007sp1 with Outlook anywhere takes a long time (1,5 minute) auth=ntlm
Posted on 2008-10-13
I have a weird problem. When I start my Outlook on a remote site. Outlook connects to my server using Outlook anywhere (rpc over https). The initial connect time is very long (1,5minute).
After this, when Outlook shows connected, everything works very fast.
The authentication is NTLM. On my old server, with Windows 2003 x64, I did NOT have this problem. On my new Windows 2008 x64 server I cannot find the problem.
I have tried disabling ipv6. Did not make any difference.
Anyone can help me out?
