SYMPTOMS
Symptom 1
On your computer running LAN Manager real mode TCP/IP, when you terminate a
PC Anywhere application from the host computer, the computer stops
responding (hangs) and the following error message appears:
Winsock Fatal Error
Remoteabort_cd():SDGetAddrPerThreadStruct()
At times, the computer hangs with a black screen.
Symptom 2
When you have a lot of screen activity on your computer running LAN Manager
real mode TCP/IP, (moving Windows around rapidly on the screen), a large
number of WinSock message requests are queued for background processing (by
WINSOCK.DLL), which results in the following FATAL error message:
DC Cache Full: Too many GetDC() calls
In addition, the system hangs and a General Protection Fault (GPF) error
message appears in Windows 3.1. In some cases, the error message appears
only when you attach a debugger to the computer.
CAUSE
STATUS
Microsoft has confirmed this to be a problem in LAN Manager 2.2b and 2.2c.
A fix to this problem is in development, but has not been regression-
tested and may be destabilizing in production environments. Microsoft does
not recommend implementing this fix at this time. Contact Microsoft Product
Support Services for more information on the availability of this fix.
