We have a server running 2008 R2, and we are using it as our primary print server for our organization of ~350 computers. All of these computers are Windows 7 x64.
The issue that we are having is that a few of our users are intermittently having all of their printers go 'offline'. There are about 15 random computers with this issue. When each computer is checked we either flush the DNS or restart the Print Spooler to resolve the issue. The thing is, if we do nothing, the printers will come back on their own.
We have ran every update on the Server as well as the local machines, removed/added smtp to the printer drivers, checked DNS, and re installed the printers in question. The issue is still happening. I have been reading and looking for an answer, but I have been coming up short. I'm running out of ideas at this point. The thing is that everyone else in the organization has no issue printing to other printers that are on the same server, which leads me to believe that it is either a printer or PC issue. Any ideas would be greatly appreciated. Thanks.
