COM Invoke failed: Error 0x800706BE

All,

I have a COM Server Component (a .Dll) which is developed by someone. When I invoke (using invoke()) a function in that COM Server, it throws the error 0x800706BE -The remote procedure call failed. Interestingly it throws this error only few times!!. it works fine for the rest of the times!!.

The issue is reported in a windows 2k8 64 bit OS & Win 7 32 bit.

1. Any idea what could be the issue?
2. would it an issue with the COM Server or COM Client ?
3. is there any way by which I c开发者_如何学Can narrow down to know the culprit?

Thanks, Bytes

ok. It seems I have found out the problem. The COM Server(.dll) was crashing the moment I called Invoke() on that. The problem seems to be in the COM Server. Hope it will be helpful for someone.
