This article was previously published under Q108071


SYMPTOMS

When an APPC application issues WinAPPCCancelAsyncRequest() after the asynchronous routine has completed, WAPPCINVALID (0xF001) is returned instead of WAPPCALREADY (0xF000). The SNA Server APPC Programmer's Guide states that WAPPCALREADY should be returned in this instance.

CAUSE

WinAPPCCancelAsyncRequest is not properly returning the WAPPCALREADY error code as documented.

RESOLUTION

An update to SNA Server 2.11 corrects this problem, so that WinAPPCCancelAsyncRequest now returns WAPPCALREADY if an asynchronous routine is being cancelled has already completed.

Microsoft has updated the following files to correct this problem:

   Windows NT:  <snaroot>\SYSTEM\WAPPC32.DLL
   Windows 95:  <win95root>\SYSTEM\WAPPC32.DLL
   Windows 3.x: <winroot>\SYSTEM\WINAPPC.DLL
                

STATUS

Microsoft has confirmed this to be a problem in SNA Server for Windows NT. This problem was corrected in the latest SNA Server for Windows NT, 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):
