SYMPTOMS
Issuing SLI_CLOSE to cancel an SLI_OPEN sometimes causes a subsequent SLI_OPEN on the same LU to fail with an LUA_CANCELLED (0x0021) primary return code.



CAUSE
When an SLI_CLOSE is issued, the SLI library calls RUI_TERM to shutdown the LU session. If a new SLI_OPEN is called on this same LU, the underlying RUI interface may complete the RUI_TERM in error, causing the SLI_OPEN to fail with LUA_CANCELLED.



RESOLUTION
A hotfix to SNA Server 2.11 SP1 and 3.0 is available to correct this problem. The updated modules are:  \system\WINRUI32.DLL  (for Windows NT clients) \system\WINRUI32.DLL (for Windows 95 clients) \system\WINRUI.DLL   (for Windows 3.x clients) \RUI.DLL             (for OS/2 clients) \DOSACS.LIB          (for MS-DOS clients)



STATUS
Microsoft has confirmed this to be a problem in SNA Server 2.0, 2.1, 2.11, 2.11 SP1 and 3.0.

This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
