There is a NETBIOS LAN/DOS session bug in MCP, eCS, and, under certain circumstances, in Warp 4 FP 15. The effect of this bug is to raise the chance of data corruption for people using DOS applications on an OS/2 network to 'almost certain'.
IBM has now successfully reproduced the bug. I have been informed that this bug will =not= be addressed in the upcoming release of fixpack 1 for MCP.
Since this problem can impact many, [and since I have been receiving many questions on it since reporting it], I have set up a web page with detailed information on the bug. The web page also contains information on subscribing to a mailing list to discuss the bug and coordinate efforts to develop some sort of workaround until and if IBM fixes the problem.
