We have been running Exchange2000 IM for the past few months and it has been working as well as expected with any problems. then all of sudden we started gettting login errors:
Exchange Instant Messaging Sign-In Faliure
The email address does not match the username and password of the person logged into this computer. Make sure you provide the correct username, password and domain for the email address.

Nothing in our network has changed!? We do not see any errors in the event viewer on the IM or Exchange Servers. Does anyone have this same type of experience? Any and all help would be welcome and appreciated.

I have IM running. The user logon by default is username@servername. If you look in the user properties in "Active Directory Users and Computers" on the "Exchange Features" tab, double click "Instant Messaging" object. In the "Instant Messaging User Address" you will see what there logon is suppost to be. For example mine is ebellardino@baiserv1.

FYI: the newest version of MSN messager that with Exchange2000 IM is version 5.0 for Win9x & 5.1 for Win2k and up.
