# Printing via TCP/IP Kills LAN Manager 2.2b MS-DOS Client

PSS ID Number: Q112197

Article Last Modified on 11-10-1999

The information in this article applies to:

- Microsoft LAN Manager 2.2b

## Symptoms

After installing a LAN Manager 2.2b MS-DOS enhanced workstation, all attempts to print to a network printer by means of TCP/IP from either MS-DOS or Windows 3.1 crash the machine.
Printing from within Windows 3.1 drops you from Windows to either the MS-DOS prompt or an unresponsive black screen. Printing from MS-DOS hangs the machine totally. Ctrl+Alt+Del may not be recognized, and a hard reboot may be required.

## Cause

An optimization in TCP/IP causes a send to return to the caller, Messenger, too quickly during the receipt of print job notification.

## Resolution

TCPTSR.EXE has been modified to address this problem.

## Status

Microsoft has confirmed this to be a problem in Microsoft LAN Manager version 2.2b. The problem is fixed in CSD00.087. Contact Microsoft Product Support Services for more information.
