SYMPTOMS
The SNA Manager Microsoft Management Console (MMC) snap-in may exit unexpectedly when a Microsoft Host Integration Server administrator tries to add a new link service.

When this problem occurs, the SNA Manager MMC snap-in logs no event messages, and it displays no error messages. If Dr. Watson (Drwtsn32.exe) is configured as the default debugger, the Drwtsn32.log file may contain an entry that resembles the following: Application exception occurred: App: mmc.exe (pid=736) When: 3/16/2007 @ 12:37:36.729 Exception number: c0000005 (access violation) […] function: RtlInitAnsiString 77fabe64 57              push    edi 77fabe65 8b7c240c        mov     edi,[esp+0xc]          ss:00886b9b=???????? 77fabe69 8b542408        mov     edx,[esp+0x8]          ss:00886b9b=???????? 77fabe6d c70200000000    mov     dword ptr [edx],0x0    ds:0006cce4=00000000 77fabe73 897a04          mov     [edx+0x4],edi          ds:00886bca=???????? 77fabe76 0bff            or      edi,edi 77fabe78 741e            jz      RtlpNtEnumerateSubKey+0x7236 (77fb4198) 77fabe7a 83c9ff          or      ecx,0xff 77fabe7d 33c0            xor     eax,eax FAULT ->77fabe7f f2ae            repne   scasb                        es:006b6361=?? 77fabe81 f7d1            not     ecx 77fabe83 81f9ffff0000    cmp     ecx,0xffff 77fabe89 7605            jbe     tan+0x48 (77fb7790) 77fabe8b b9ffff0000      mov     ecx,0xffff 77fabe90 66894a02        mov     [edx+0x2],cx               ds:00886bcb=???? 77fabe94 49              dec     ecx 77fabe95 66890a          mov     [edx],cx                   ds:0006cce4=0000 77fabe98 5f              pop     edi 77fabe99 c20800          ret     0x8 FramePtr ReturnAd Param#1 Param#2  Param#3  Param#4  Function Name 0006CCF8 684059DB 000D7BC1 006B6361 00000000 00000000 ntdll!RtlInitAnsiString 00000B29 00000000 00000000 00000000 00000000 00000000 remcfg!fAddRegistryEntry Notes
 * > Stack Back Trace <*
 * The Drwtsn32.log file entry that is included here occurred when a user tried to install a new distributed link service on a Host Integration Server 2000 server. If a user installs a new DLC 802.2 link service, the Drwtsn32.log file entry contains 802cfg!fAddRegistryEntry instead of remcfg!fAddRegistryEntry.
 * The SNA Manager MMC snap-in is included with Host Integration Server.
