This update fixes the following issues for print server failover clusters that are running Windows Server 2008 R2. We recommend that you install this update on all the print server failover cluster nodes that are running Windows Server 2008 R2 to make sure that basic functionality and that basic manageability is maintained.

Issue 1

Consider the following scenario:
  • A shared printer is installed on a print server failover cluster that is running Windows Server 2008 R2.
  • The print processor of the related driver has multiple dependent files.
  • The print server fails over to another node.
In this scenario, the shared printer may be missing on the new node after the failover operation.

Issue 2

Consider the following scenario:
  • A shared printer is installed on a print server failover cluster that is running Windows Server 2008 R2.
  • Some clients open connections to this shared printer.
  • The print server fails over to another node.

In this scenario, the spooler service may stop responding after this printer server resource fails over to another node. Therefore, all print jobs fail.

Issue 3

When you use the Print Back-up Restore Migrate utility (Printbrm.exe) to restore printers on a print server failover cluster that is running Windows Server 2008 R2, some printers cannot be restored, and you receive the following error message:

1081 invalid printer name
