You may see a stack trace similar to the following sample trace in the Drwtsn32.log file after the error occurs: FramePtr RetAddr Param1 Param2 Param3 Function Name 29f7f548 76dc1954 02774fd8 001843f0 00000000 FPNWCLNT!wcsupr+0x31 29f7f570 76dc1715 02763090 017980f0 29f7fc93 FPNWCLNT!MNSWorkstationValidate+0xb7 29f7f684 76dc1899 00000002 02763074 00000001 FPNWCLNT!Msv1_0SubAuthenticationRoutine2+0x564 29f7f6b4 75b88612 00000002 02763074 00000001 FPNWCLNT!Msv1_0SubAuthenticationRoutine+0x25 29f7f814 75b82584 00000002 02763074 00000001 MSV1_0!Msv1_0SubAuthenticationRoutine+0x1c7 29f7fbf8 75b82d6b 01796588 00000001 00000002 MSV1_0!MsvpSamValidate+0x250 29f7fc40 501816fd 01796588 00000001 00000002 MSV1_0!MsvSamValidate+0x55 29f7fc94 50181bf8 00000002 00000002 02763074 NETLOGON!NlpUserValidate+0x85 29f7fce0 50185209 02763010 02763038 02763050 NETLOGON!NetrLogonSamLogon+0x239 29f7fe20 77e111b7 29f7fef0 0179b438 29f7fef0 NETLOGON!logon_NetrLogonSamLogon+0x18d 29f7fe5c 77e112e6 5018507c 29f7fef0 29f7ff34 RPCRT4!DispatchToStubInC+0x34 29f7feb0 77e11215 29f7fef0 00000000 29f7ff34 RPCRT4!?DispatchToStubWorker@RPC_INTERFACE@@AAEJPAU_RPC_MESSAGE@@IPAJ@Z+0xb0 29f7fed0 77e1a3b1 29f7fef0 00000000 29f7ff34 RPCRT4!?DispatchToStub@RPC_INTERFACE@@QAEJPAU_RPC_MESSAGE@@IPAJ@Z+0x41 29f7ff40 77e181e4 02762fe8 00000190 29f7ff90 RPCRT4!?ReceiveOriginalCall@OSF_SCONNECTION@@QAEHPAUrpcconn_common@@I@Z+0x14b CAUSE ===== This behavior occurs because the wcsupr function in the stack trace is expecting to pass a null-terminated string as an argument. The problem occurs if, for some reason, it is passed a string that is not null-terminated.
