I've tested web service on my own computer running XP & IIS. It works fine on XP stand alone machine. Someone please help me out with following

My external server is NT 4.0 with IIS 3.0 Version 4.0 - SP 6.

1. Do I need to install the SOAP SDK on NT as well?

2. While trying to test the WS it comes with the error
OLE IDispatch exception code 0 from Client:
WSDLReader:Loading of the WSDL file failed
HRESULT=0x80070057 - WSDLReader:XML Parser failed at
linenumber 0, lineposition 0 reason is: Access is denied

3. The server has authentication enabled. Do I need to setup ConnectorProperty? Where can I get some help on this?

Thanks
Ben
