SYMPTOMS

When you configure the ServiceProvider Priority values in the registry to modify the DNS search order, the search order may not seem to be changed.

CAUSE

A ServiceProvider registry key exists (with associated registry values) at the following registry location:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\
   ServiceProvider

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSTCP\
   ServiceProvider

RESOLUTION

To resolve this issue, use either of the following methods:

Method 1

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

Create the registry key being referenced by Winsock. To do so, use the following steps:

1. Use Regedit.exe to open the following location:

         HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
   

2. On the Edit menu, point to New, and then click Key. Name the new key MSTCP.

3. Click the new MSTCP key, point to New on the Edit menu, and then click Key. Name the new key ServiceProvider. The registry path should look like this:

         HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSTCP\
         ServiceProvider
   

4. Click the new ServiceProvider key, point to New on the Edit menu, and then click Binary Value. Create the following new binary values:

       - DnsPriority
       - LocalPriority
       - HostsPriority
       - NetbtPriority.
   

5. Set the priority values as appropriate.

Method 2

Obtain the update mentioned in the "Status" section of this article. This update causes Winsock to reference the correct location for the ServiceProvider key in the registry.
