Dr. Watson Errors When Starting the Spooler Service

When you try to start the Spooler service, you may receive the following Dr. Watson error message: Also, you may receive the following error message:

This behavior can occur if a print monitor utility or printer spool file or files are damaged. This can occur when you use a third-party print monitor utility or Microsoft Windows NT print monitors.

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, perform the following steps, testing to determine if the issue is resolved after each step, and if it is, do not perform the remaining steps:

1. Configure the print server for online use:
   1. Click Start, point to Settings, click Control Panel, and then double-click Services.
   2. Click Spooler, and then click Startup.
   3. Configure the Spooler service to log on using the System account and to interact with the desktop, and then click OK.
2. Eliminate any extra .shd and .spl files:
   1. Remove or rename the .shd and .spl files from the various spool folders located in the %SystemRoot%\System32\Spool\Printers folder. Note that you lose pending print jobs, but the configuration information should be intact.
   2. Remove or rename any unused or old .tmp files in the Temp folder.
3. Delete the printer through the registry, and then reinstall it:
   
   NOTE: Normally, you can delete a printer by using the Delete Printer command. However, the printer is not actually deleted until the next time the Spooler service starts. Because in this case the Spooler service does not start, you cannot use the Delete Printer command. Deleting the following keys from the registry requires you to reinstall the printer drivers and recreate the printers, because the printer is deleted from the print share.
   1. Use Registry Editor to delete the appropriate registry keys:
      
      Local Printer
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print \Environments\Windows NT x86\Drivers\Version-2\printer name
      
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print
      \Printers\printer name
      where printer name is the name of the local printer.
      
      Network Printer
      HKEY_CURRENT_USER\Printers\Connections\server name
      
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
      \Print\Providers\LanMan Print Services\Servers\server name
      \Printers\printer name
      where server name is the name of the server the printer is on and printer name is the name of the network printer.
   2. Restart the computer, and then reinstall the printer.
4. Delete the print monitor from the registry:
   1. Use Registry Editor to locate and delete the print monitors from the following registry key:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors
      NOTE: Each print monitor is listed in a subkey of this registry location.
   2. Restart the computer.
