CAUSE ===== The SNA Server LUA RUI and SLI thunking DLLs were not properly allocating and locking memory for verb control blocks, causing 16-bit RUI thunking calls to fail to complete. RESOLUTION ========== An update to SNA Server and SNA Workstation 2.11 (newer than Service Pack 2) and SNA Server 3.0 are available to correct this problem. STATUS ====== Microsoft has confirmed this to be a problem in SNA Server and SNA Workstation version 2.11 and SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack.
