Server 2 Server http calls....Update
An update on the issue:
I've built an ActiveX DLL (RemSvrInt.dll) that references MSXML3.dll internally.
When I built an Standard Exe test harness to test my RemSvrInt.dll and deployed
it onto my NT Server box it ran OK. I was able to create an MSXML2.XMLHTTP30
object and call the send method posting a string to it. (It failed a few
Afterwards, I took my RemSvrInt.dll and referenced from another ActiveX DLL
that is created by IIS. When a call was made to my RemSvrInt.dll it failed
on the MSXML.XMLHTTP30.send( ) method reporting Method "~" of object "~"
failed. Being ActiveX dll they are running in the IIS server process which
it doesn't seem to like one bit.
1: Server 2 Server calls work sporadically
2: The send method of MSXML.XMLHTTP30 does not function inside of an IIS
process (btw - this is on a client machine which is using PWS and doesn't
have NT Server security!)
Anyone have any thoughts?
