Intermittent SOAP Timeout Errors - XML SOAP

Hi,

I have an ASP application making soap calls and am intermittently getting the following error:
--------------------------------------------------------
Connector:Connection time out. HRESULT=0x800A1527 - Client:An
unanticipated error occurred during the processing of this request.
HRESULT=0x800A1527 - Client:Sending the Soap message failed or no
recognizable response was received HRESULT=0x800A1527 -
Client:Unspecified client error. HRESULT=0x800A1527
--------------------------------------------------------

I do not believe any part of the code is the problem, as when running the same code that the does the soap call over and over again, it may work 3 times in a row and then fail once, then work twice and fail, etc...

The hardware environment is very complex.

QUESTION: What tools can I use to see why the soap call might be failing? I want to be able to capture the soap / http communication between the servers involved?

QUESTION: Can anyone point me to a good resource to tell me what information to gather or how to troubleshoot soap errors?

I have used a free app call TCPTrace in the past, but I can't get it to work with soap calls (mssoapinit doesn't like a url with a port number in it).

Thanks,
Brent
