Ent Mgr. Management-CurrentActivity-Application - Error?

[Noble007]

I'm having a problem with couple of users on our network not connecting to SQL exactly right. In the CurrentActivity window under the application column these users are not showing the authenticated usernames. Example: it should be username@computername but all that shows is @computername. These users get weird security problems that I have not been able to resolve. Our network admin is looking into it but he's not sure why these users should be any different than the rest. Any suggestions?

Checked users' desktop to see how did they connect to sql server?

Can they connect to server using sql client tools (query analyzer ?).

Application name column may not be set by all applications.

All the users are using our MRP
(Fourth Shift). The other users are reporting correctly.

Does MRP conenct to sql via odbc dsn? If so, check dsn settings for those users.

Check the MDAC version on those machines.
