After upgrading our web server to Service Pack 1 on Windows 2003 Server, we
began to run into an authentication failure with the Marketing Web Service
using CS2002 FP1. Whenever the site tries to access the Web Service we get
the following error:
An authentication failure occurred. Valid credentials could not be
supplied
for the Web service with URL
'http://koldwebservice.kold.com/MarketingWebService/MarketingWebService.asmx'.
We load balance the web service using Windows Load Balancing so the Web
Service has a different IP and Server URL than the original site as
follows:
Site: http://store.kold.com/
Marketing Web Service:
http://koldwebservice.kold.com/MarketingWebService/MarketingWebService.asmx
Nothing in the IIS or security configuration has changed.
