KB172606 - SNA Server Access Violation When Receiving Invalid XID Frames

SYMPTOMS

SNA Server may encounter access violations or hard-coded break points within Snaservr.exe in an environment where corrupt 802.2 frames are being sent as a result of a bad network card or network card driver. The failures result in a Drwtsn32.log that may show the following type of failures:

Application exception occurred:
App: snalink.DBG (pid=216)
When: 7/22/1997 @ 13:53:4.828
Exception number: 80000003 (hardcoded breakpoint)

In the Windows NT Application log the following event will be logged with the same timestamp as the hard-coded break point:
