TITLE :Application Error When Installing DLC
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:
------------------------------------------------------------------
The information in this article applies to:
- Microsoft Windows NT operating system version 3.1
- Microsoft Windows NT Advanced Server version 3.1
------------------------------------------------------------------
SYMPTOMS
========
You receive an application error from SPOOLSS.EXE when reinstalling
the data link control (DLC) protocol.
CAUSE
=====
This error may occur because you still have a printer set up in Print
Manager that is printing to a Hewlett-Packard (HP) network port.
RESOLUTION
==========
To recover from the application error, do the following:
1. Choose the End Task button in Task Manager to exit Control Panel.
2. After exiting Control Panel, the DLC Setup task will appear in Task
Manager. Choose End Task to exit this as well.
3. Run Control Panel and choose the Network icon. In the list of
installed protocols, select DLC and choose Remove (because the
installation was only partially successful).
4. Exit Control Panel, but do not restart the system yet.
5. Start Print Manager and remove the printer that is on the HP
network port.
6. Restart the system.
7. Run Registry Editor (REGEDT32.EXE).
WARNING: Using Registry Editor incorrectly can cause
serious, system-wide problems that may require you to
reinstall Windows NT to correct them. Microsoft cannot
guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own
risk.
8. Within Registry Editor select the following key
\HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Print\Monitors
and remove the following key and all of its subkeys:
\Hewlett-Packard Network Port
8. Restart the computer.
9. Run Control Panel and choose the Networks icon. Reinstall DLC.
If you have removed DLC without removing the printer but have not yet
tried to reinstall the protocol, start at step 5.
MORE INFORMATION
================
If DLC is currently installed on your system and you have a printer
that is using the protocol to print to an HP network port, to safely
remove the protocol you must first either remove the printer or change
its settings so it no longer prints to the HP network port. Removing
the protocol without removing or changing the printer port will not
immediately cause any errors, and the printer will still appear in
Print Manager. However, any attempt to reinstall the protocol will
give an application error from SPOOLSS.EXE and cause Control Panel to
hang, resulting in a partially installed protocol.
Once you have removed the protocol, removing the printer will not
allow you to reinstall DLC without receiving an application error. The
error occurs because there are still references in the Registry to the
HP network port that were not removed when the protocol was removed.
