We have a Server 2008 R2 domain controller that has the Print Management role installed. Just recently it has started to cause problems:
Several times now I have arrived 8am to find all 12 shared printers are offline and I cannot access any MMC, either directly via start menu or via console and adding snap in - they all just hang indefinitely. Any changes in Active Directory on other servers then take an age to propagate to this DC, as do mailbox permissions set on the Exchange server. Windows Explorer would hang intermittently on DC, though network access to shares was still fine. The only way to clear this is to reboot the DC.
We switched all printers over to another server, rebooted the DC and the server ran OK for 2 weeks. Switched people back to printing via this DC and problem had recurred within 1-2 days - this happened twice. Printing is now through another server and the DC has been OK with no hanging MMC/explorer for 2 weeks plus, though this is not ideal.
On top of this, even when the server appears to be working OK, printers are working and I can open ADUC/explorer etc, I cannot open the Print Management console directly via Start menu - error message is:
"MMC Cannot open the file c:\windows\system32\printmanagement.msc
"This may be because the file does not exist, is not an MMC console or was created by a later version of MMC"
The file is still there, and all of the permissions are consistent with another server that works perfectly. Print Management loads without problems via MMC. Nothing logged in eventviewer.
Can anyone help? At the moment the temporary print server is playing havoc with duplexing from Windows 7 PCs, otherwise I would be tempted to just make the printer switch permanent!
