Print jobs may have incorrect owners when you share a printer from a Windows Server 2008-based computer or from a Windows Vista Service Pack 1-based computer

Consider the following scenario:

• You share a printer from a Windows Server 2008-based computer or from a Windows Vista Service Pack 1 (SP1)-based computer.
• Two users connect to the shared printer by using the same print client. For example, they connect by using a terminal server.

In this scenario, every print job that is sent from this print client has the same owner in all print queues. The owner is the first user who sends a print job from this client after the printer server is restarted.

This problem also causes some security-related issues. Because the permission settings for a print job are based on the permission settings of its owner, the first user can manage the print jobs of later users even though the first user did not send these print jobs. Additionally, later users who send print jobs may be unable to manage their own print jobs.

This problem occurs because the print job is sent in the wrong remote procedure call (RPC) context.
