SYMPTOMS
The 3270 applet that is included with SNA Server may send a message using the Exception Response protocol even though only the Definite Response protocol has been negotiated during the bind. Therefore, the 3270 emulator stops responding (hangs) unexpectedly.



CAUSE
The 3270 applet does not check the session parameter all the time to determine what type of request it should send.



STATUS
Microsoft has confirmed this to be a problem in SNA Server version 2.11 and 2.11 Service Pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
