CRM 3.0 HTTP 401 Unauthorized access error
Posted on 2009-04-16
This problem started after making the following changes to the network:
Configured SBS server to act as DHCP Server (Have since reverted back to all IP's, etc)
Switched modem and ISP provider
New ethernet HUB
Computers can connect to everything else, including other IIS resources. We can access some entities like queues, articles, quick campaign, etc, but user owned entities can't be accessed and throwing this error.
We have also received HTTP 403 error, but have seemed to fixed this error.
The request failed with HTTP status 401: Unauthorized.
