I am trying to access a Project Server 2007 web service. I am working on a Windows 2003 server with IIS 6.0 installed. When I try to connect to the webservice after adding a web reference to my VS2005 code I get HTTP 401 Unauthorized error.
I have tried the following things and yet am unable to connect. Please let me know if you can shed more light on it. Here are the symptoms.
I AM able to view / browse the services in the browser.
I tried setting Credentials to Network Credentials with UID / PWD and DefaultCredentials without luck.
I tried to check / uncheck anonymous access for the services directory in IIS ( Should I be doing it at an App Pool level ? )
I changed the Account used for anonymous access to Administrator and its respective password from Directory Security.
I have tried to update web.config file of my client app to set authentication to Windows and impersonate = true.
Do you know if there is anything else that I can do / try ? Help would be much appreciated.
