SYMPTOMS
An A Server access violation (0xC0000005) may occur in routine s1pnsuns if an AS/400 responds with an invalid BIND +RSP.



CAUSE
The SNA Server service (Snaservr.exe) does not parse the user data in the BIND +RSP correctly. An invalid BIND +RSP from AS/400 may lead to an access violation.



RESOLUTION
A hotfix to SNA Server for Windows NT, version 2.11 (post SP2) and version 3.0 (post SP1) is available to correct this problem.



STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.11 Service Pack 1, 3.0, and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack.
