When I try to open a form that is in use by another user, I get a message at the lower left corner of the screen telling me "This form is currently locked by another user on xxxxx", where the xxxxx is the computer name of a computer on our network.

This feature is helpful when I need to gain access to the form.  I also look at the users in the Server Administration screen to see who is logged onto the system.

Lately, I've run into an issue where computers are logging on and they are showing another computers name.  For example, a computer with a name of "Quality1" is showing up as "Victor2".   This is causing a lot of confusion. 

Do you have any idea what can be causing this name change?
