Case Summary: HTTP Error 401 error
ID: 255
Date Created: 02/09/2001

Problem Type: Problem Report
Item: Tech+Center
Resolution:
Users reports getting error for the techsupp.dll file:
HTTP Error 401
401.3 Unauthorized: Unauthorized due to ACL on resource
This error indicates that the credentials passed by the client do not have
access to the particular resource on the server. This resource could be
either the page or file listed in the address line of the client, or it
could be another file on the server that is needed to process the file
listed on the address line of the client.
Please make a note of the entire address you were trying to access and then
contact the Web server's administrator to verify that you have permission to
access the requested resource.

We checked the file permissions for the techsupp.dll and the css_access.dat file and it may not been some authenication/file permmission problem for the techsupp.dll so we reset the file permission to just everybody full control and remove other permission settings. Front Page extensions were recently installed on the site.

After resetting file permissions and rebooting the server it now works again.
