Hello all,

We just recently upgraded the NT4 domain to AD 2003, and Exchange 5.5 to Exchange 2003. Ever since the upgrade, some of the remote users are having problem accessing their email through the VPN. We are using Check Point VPN-1 Secure Client...

After the users got authenticated, and open Outlook, the logon prompt would then pop-up asking them to enter their user name and password, which is their NT logon info. This didn't happen before, and only happened after the upgrade.

Did anyone know what is the problem here, and what can I do to fix this problem. Thanks

Hi

Open Outlook and slick on tools services and properties of Exchange server , click on the advanced tab and see the option for logon network security.
It should be NT password authentication.

Hope this helps.

Regards
