SYMPTOMS
The TN3270 Server may end "silently," without generating a Drwtsn32.log or logging an Event 624 in the Windows NT Application Event Log.

An LUA application may also fail with an access violation when calling the GetLuaReturnCode API; this occurs when it is attempting to map an error code that the GetLuaReturnCode API does not know how to map.



CAUSE
The GetLuaReturnCode function (within Luastr32.dll) may encounter an access violation when attempting to map an error that it doesn't know how to map. This can occur when mapping either an LUA RUI or SLI error code.



RESOLUTION
An update to SNA Server 2.11 Service Pack 1 and 3.0 is available to correct this problem. The updated modules are:

\system\LUASTR32.DLL

\system\WINRUI32.DLL

\system\WINSLI32.DLL



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