You experience slow printer performance on a clustered print server in Windows Server 2003 and in Windows 2000 Server


You may experience slow printing performance on a Windows Server 2003-based or Windows 2000 Server-based server cluster that is configured as a printer spooler. When you troubleshoot this problem, the following behavior occurs:
  • Print jobs take an increasingly long time to print.
  • If you fail over the cluster node to another node, the problem recurs.
  • If you edit the Windows registry on the cluster node to increase the node's number of connections to itself, the problem recurs.
  • Under the Shared Folders\Open Files administrative snap-in, in Computer Managment\System Tools, the server shows multiple Open File connections to \PIPE\spoolss. These connections do not list an owner.


This problem may occur if the Print Spooler service stops responding (hangs). A scenario may occur where the Print Spooler service loops back on itself when it makes a remote call (RemoteGetPrinter) to a local printer. This behavior causes the Print Spooler service to exhaust all the server's available connections to itself. The Print Spooler service stops responding because it is waiting on a thread that is trying to load a print driver.

This problem may occur if you try to open a connection to a shared printer that no longer exists. For example, this problem may occur in the following scenarios:
  • A printer share is renamed, and you try to connect to the printer by using the old name.
  • A network printer is local to a cluster node, and you try to connect to it when the cluster node fails over.
In these cases, the Print Spooler service routes the incoming OpenPrinter call to local print spoolers (including the cluster). If the local print spoolers do not recognize the requested printer name, the spooler passes the calls to the remote print provider (Win32spl.dll).
