SYMPTOMS
The Distributed File System service (DFSSVC) may take longer than expected to start on a Microsoft Windows Server 2003-based server that belongs to a Microsoft Windows NT 4.0-based domain. When you restart the service, you may notice a delay of up to 30 minutes before the service starts.



CAUSE
This issue occurs because of the Distributed File System (DFS) site-awareness feature in Windows Server 2003. The Windows Server 2003-based computer uses the DFS site-awareness feature to search for resources that are closer on the network to a DFS client computer and that let the DFS client computer access these resources on request.



RESOLUTION
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.To resolve this issue, set the value of the  registry entry to 1. When you set the value of the  registry entry to 1, the DFS site-awareness feature in Windows Server 2003 is disabled. Therefore, Windows Server 2003 does not use the DFS site-awareness feature to search for resources that are closer to the DFS client computer.

To do this, follow these steps:  Click Start, click Run, type regedit in the Open box, and then press OK. In Registry Editor, locate and then click the following registry subkey:

 On the Edit menu, point to New, and then click DWORD Value. Type DfsDisableSiteAwareness, and then press ENTER. Double-click the DfsDisableSiteAwareness value, type 1 in the Value data box, and then click OK.

Note You can set the value of the  registry entry to 0 (zero) to make Windows use the DFS site-awareness feature again. Exit Registry Editor.</li></ol>
