SYMPTOMS
After you upgrade to Microsoft SNA Server 3.0 Service Pack 2, one of the
following symptoms may occur while the server is running:
CAUSE
In SNA Server 3.0 Service Pack 2, client logon requests are now handled
from multiple threads within the SnaBase or SNA Server service. If two
concurrent client logon requests occur that both use the LSA authentication
method (that is, Windows 3.x clients, or Windows NT services that run under
the local system account), the SnaBase or SNA Server memory heap may become
corrupted. This occurs because LSA logon is not thread-safe, so two
concurrent LSA logon requests from the same process can result in memory
corruption.
STATUS
Microsoft has confirmed this to be a problem in SNA Server version
3.0 Service Pack 2.
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
