SYMPTOMS
Inetinfo may generate an access violation or a heap check debug break point when the IISAdmin service is shutting down. When this problem occurs, either of the following symptoms may occur:  An access violation may occur at a random location, caused by an address that had been decremented.  If heap validation is enabled, there may be a debug break similar to: HEAP[inetinfo.exe]: Invalid Address specified to RtlFreeHeap( 8e0000, 436f10 ) eax=00436f08 ebx=00436f08 ecx=01adf33c edx=01adf0d6 esi=008e0000 edi=00436f08 eip=77fa018d esp=01adf2bc ebp=01adf2c0 iopl=0        nv up ei pl nz na pe nc cs=001b  ss=0023  ds=0023  es=0023  fs=0038  gs=0000             efl=00000202 ntdll!DbgBreakPoint: 77fa018d cc              int     3 0:014> kb ChildEBP RetAddr Args to Child 01adf2b8 77fb6cf6 01adf2d4 77fb5fbe 00436f08 ntdll!DbgBreakPoint 01adf2c0 77fb5fbe 00436f08 008e0000 00436f10 ntdll!RtlpBreakPointHeap+0x26 01adf2d4 77fb5234 008e0000 00436f08 77fb510c ntdll!RtlpValidateHeapEntry+0xd0 01adf34c 77fa762d 008e0000 50000061 00436f10 ntdll!RtlDebugFreeHeap+0xb3 01adf3ec 77fcac40 008e0000 40000060 00436f10 ntdll!RtlFreeHeapSlowly+0x4e 01adf490 6e5a21d8 008e0000 00000000 00436f10 ntdll!RtlFreeHeap+0x53 01adf4a0 6e5a21e2 00436f10 6c7e4280 010a94b0 IisRTL!IisFree+0x12 01adf4a8 6c7e4280 010a94b0 031027b8 00436f00 IisRTL!BUFFER__~BUFFER+0xd 01adf4c4 6c7e4255 010a8f30 010e1c08 010a94b0 metadata!CMDBaseObject__~CMDBaseObject+0x9f 01adf4e0 6c7e4255 010a70a8 004367c0 010a8f30 metadata!CMDBaseObject__~CMDBaseObject+0x74 01adf4fc 6c7e4255 00000000 010a70a8 00000000 metadata!CMDBaseObject__~CMDBaseObject+0x74 01adf518 6c7e664a 69d0a180 00000000 6c7e65f0 metadata!CMDBaseObject__~CMDBaseObject+0x74 01adf524 6c7e65f0 00000000 0028aba0 00000000 metadata!TerminateWorker+0x55 01adf548 6c7e1727 00000000 69d02b63 00436544 metadata!TerminateWorker1+0x6a 01adf550 69d02b63 00436544 00000001 00000000 metadata!CMDCOM__ComMDTerminate+0x7
