Exchange 2007, outlook 2000 issue
Dear All,
I am facing a issue with outlook 2000. I will explain you the details.
I have exchange 2007 environment.
1 HUB Transport server.
1 CAS Server.
2 mailbox servers in cluster.
We were in the process of migrating our network from old subnet 128.102.30.x to 10.100.1.x subnet. After migrating few computers we are facing issue with outlook 2000 users.
When we open outlook 2000 we are getting this error message.
"Your MS Exchange server is unavailable"
You can retry connecting to the server using network or work offline and connect using dial up networking.
The network did not respond in a timely fashion to determine the existence of an exchange server, you may retry and continue waiting for a response or work offline."
When i click on retry it connects and i am able to send and receive emails. But while opening outlook 2000 it took lot of time and gives the above error message.
I reverted back to old ip range but still facing the same issue. I am able to ping, telnet on port 25 to HUB Transport server from the client which is having the outlook issue.
I am able to telnet port 443 to CAS Server from the client which is having the outlook 2000 issue.
I am able to telnet port 135 to mailbox server from the client which is having the outlook issue.
On client i am running windows xp and outlook 2000, other users dont have any issue. only 3-4 users are facing this issue. other users are also running windows xp and outlook 2000 and dont have any problem.
Any help will be really appreciated. Thanks.

Does OWA works fine for them ?
Is there any Host file entries ?
