How to repair Small Business Server when the computer name reverts to Win-*******


Windows Server versions including Small Business Server(SBS), and Windows Server 2008 R2, and possibly others may experience this issue.

ISSUE:

Computer name reverts to WIN-******* after a hardware change.

The Issue has also been seen after a normal reboot and when invoking Last Known Good configuration.

The following registry keys may change from the original machine name, which is possibly still listed correctly in System Properties to a WIN-********** style machine name.

  • HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Hostname=[name]
  • HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\NV Hostname=[name]
  • HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveComputerName\ComputerName=[name]
  • HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName\ComputerName=[name]


RESOLUTION:

(Note: This should only be attempted as a last effort or if changing them per the following Microsoft article has failed. See article http://support.microsoft.com/kb/102987
1. Edit registry entry HKLM\SYSTEM\CCS\Control\ComputerName\ComputerName containing the incorrect value of WIN-********* to the correct machine name.
The key for "ActiveComputerName" is set on startup from the key containted in "ComputerName" so changing both is not necessary.
Changing the keys under TCPIP may only be required if they have also changed to WIN-********** rather than the correct machine name.
2. Reboot the server and the name should now be changed and the server should function as normal.
