Hi Guys, We have an Exchange Server (2003 std SP2). When we use OWA we get an error page saying "the local security authority cannot be contacted" when a user enters an incorrect password. The user can login fine if the correct user password is entered. I know this probably sounds like I don't need to worry about anything, but I would rather fix the issue in case it is indicitive of a more serious problem. This problem occurs whether we use HTTP or HTTPS. We don't use form based authentication, although we plan to soon. The only recent change we have made is to enable RPC over HTTP, which also works fine! Can anyone help me with this problem? Thanks in advance. Niall.

I face the "the local security authority cannot be contacted" problem now, How did you fix your problem last time, can give me some hints. thanks.
