There is about a 20- to 30-second delay in Windows Server 2008 or in Windows Vista when you open a network drive, and its target folder is a DFS share

Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Server 2008 or Windows Vista.

  • You install Service Pack 2 (SP2) for Windows Server 2008 or for Windows Vista. Or, you install hotfix 959488 on a computer that is running Windows Server 2008 Service Pack 1 (SP1) or Windows Vista SP1.

  • You create a network drive on the computer, and the target share folder is a Distributed File System (DFS) shared folder.

  • You try to open the network drive.

In this scenario, there is about a 20- to 30-second delay before the network drive is opened.

Cause

This problem occurs because the DFS client does not correctly handle a returned code. This behavior causes the DFS client to perform some unnecessary actions. Therefore, a 20- to 30-second delay occurs.

The problem first occurs after hotfix 959488 is installed. Because the hotfix is integrated into Windows Server 2008 SP2 and into Windows Vista SP2, you also experience the issue after installation of those service packs.

  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section.
