Workstation becomes invisible
We upgraded to Server 2012 and Windows 7 over Easter. All of the admin workstations were set up the same and are fine except for the Office Manager's. It has a colour printer connected and shared with two other workstations in the office. I get called down because they can't print. I can't ping the offending workstation but it can ping out. Taking it out of the domain and putting it back doesn't help but changing the computer's name does. It's now on its third name. I'm presuming a dns issue but I can't think what.
