To resolve this issue, edit the registry to make the Spooler service  dependent on the Server service. If you do so,  the Spooler service does  not  start until the Server service is running.

To create this dependency:  

  1. Click Start, and then click Run.

  2. In the Open box, type regedt32, and then click OK.

  3. Locate and click the following registry key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Spooler

  4. Click Add Value on the Edit menu. 

  5. Type DependOnService in the Value Name box.

  6. Click REG_MULTI_SZ in the  Data Type box,  and then click OK.

  7. Type LanmanServer in the Data box, and then click OK.

  8. Click Exit on the Registry menu  to quit  Registry Editor. 

  9. Restart your computer.
    10.
