Troubleshooting LAN Manager Trap Screens for OS/2 Version 1.3

MORE INFORMATION

A trap is an error condition detected by the central processing unit (CPU) after the execution of a software instruction. Traps that occur in the OS/2 operating system are not defined by OS/2, but by Intel, the designer of the microprocessor that OS/2 was designed for. The most comprehensive documentation on traps is the Intel manual for the 80x86 which details traps and their causes.

Quick Fixes for Trap Screens

• Uninstall the application or hardware that was just installed.
• Replace the hardware that is failing.
• Install the LAN Manager 2.2b patch available from ftp.microsoft.com, at \\ftp\data\softlib\mslfiles\lm22b.exe
• If the LAN Manager 2.2c files were just installed, remove them because they are for LAN Manager clients only.

Information From Trap Screens To Collect

From the example trap screen below: collect the following data:

• Trap: D
• CS: 0A80
• IP: 0057
• CSLIM: 17A4
• Internal Processing error: 0228:37CD
• Any file referenced: ELNK3$

Notes on Trap Screens

• Start with the first KB search example, then broaden searches as necessary.
