HTTP 403 Forbidden in a SharePoint site when adding members

Posted at 2007-09-03 07:58 by Wictor Wilén in .NET , SharePoint with 5 comments.

When I was installing a new Windows SharePoint Services 3 site today I HTTP 403 Forbiddenstumpled upon an error I've never seen in SharePoint before. It was when I was trying to add new users in the People and Groups administration. It was not a "normal" error page but instead a  HTTP 403 Forbidden message was thrown when going to the /_layouts/aclinv.aspx page. This was on a brand new server instance, with everything patched and up to date.

After some research I came across a thread on MSDN forums where this is discussed. Some suggests renaming the web.config file, refreshing the page, renaming web.config back and the try again as one possible solution, this did not work for me.

The second suggestion was to remove an ASP.NET version 2 hot fix, KB928365, and it helped me! Now I can add users and groups the the WSS site. Remove it using Add or Remove programs, and don't forget to check the Show Updates checkbox.

Screenshot from websnpr Thank you for your post. I ran into this issue after installing Sharepoint Services and didn't find much on the MS site. This fixed it for our installation.

Screenshot from websnpr What if this KB or HF is not installed? I've checked both locations in the Add/Remove and in C:\Windows and KB928365 was not found, but the HTTP 403 error continues happen.

Screenshot from websnpr if you host your sharepoint web applications somewhere other than the default location that IIS/SP uses; check to ensure that the Users group have read to the Bin directory of the affected application. For some reason when this particular app was created it failed to add the Users group to the Bin directory with Read as it normally would under normal circumstances. This is easily testable and fails and succeeds with consistency.
