SYMPTOMS
APPC password substitution fails intermittently. The APPC Password Substitution feature was added in SNA Server 2.11.



CAUSE
The password substitution code in the APPC library occasionally generates an incorrect password token. The incorrect token causes conversation initiation to fail with a security error. Because the error occurrs very rarely, it is typically seen only in situations where a large number of conversations are started in a short time. For example, an ODBC application may generate thousands of queries an hour, and suddenly fail with a security error after two hours of execution.



RESOLUTION
The SNA Server and SNA Server client APPC libraries have been updated to correct this problem.



STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.11 and 2.11SP1. This problem has been corrected in the latest U.S. service pack for SNA Server version 2.11.
