SYMPTOMS
When acquiring a session with a 16-bit LUA application using the SNA Server Windows 3.x client software, the following error may be reported by Drwatson.exe:

WNAP had a 'Null Selector (Read)' fault at WINRUI.



CAUSE
Using the LUA_correlator field instead of the LUA_sid field within the RUI_INIT will cause this error.



RESOLUTION
To resolve this problem:
 * Use the LUA_SID field in the RUI_INIT instead.

There is no functional difference.



STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.0, 2.1, 2.11 2.11SP1, and 3.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
