Symptoms

Assume that you connect to a network printer that is hosted on a print server from a client computer that is running Windows 7 or Windows Server 2008 R2. The print server goes offline and then comes back online. In this situation, the client computer still displays the connection status of the network printer as offline.

Cause

This issue occurs when a restricted client thread detects an offline print server. In this situation, Windows registers a polling loop to check the status of the print server. After the polling loop is registered, Windows queries the print server periodically to check whether it is back online.

In rare cases, a client thread that has a restricted token detects that a print server is offline. In this situation, Windows registers the polling loop in the context of this thread. However, the thread does not have sufficient rights to query the print server. Therefore, the polling request fails.

Resolution

This hotfix is also available at Microsoft Update Catalog.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version
