SYMPTOMS
After opening more than 256 transaction programs from a single Windows NT application, a TP_STARTED request may stop responding.
CAUSE
The internal APPC callback function for the get_server_list and get_default_lu's remote procedure calls (RPCs) assume that SNADMOD will return only an eight-bit TP control block index. However, if the application has already opened more than 256 transaction programs, the SNADMOD could return a larger value, causing the APPC interface to fail to respond to the TP_STARTED request.
STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.11 and 3.0. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

The updated module is <snaroot>\system\Wappc32.dll.
