CAUSE ===== The WINMGT.H file is missing the proper packing statements. RESOLUTION ========== To resolve this problem, add these lines to the WINMGT.H include file. At the beginning of these header files, these statements should be added: #ifdef WIN32 #pragma pack(4) #endif At the end of these header files, these statements should be added: #ifdef WIN32 #pragma pack() #endif STATUS ====== Microsoft has confirmed this to be a problem in SNA Server for Windows NT.
