We are running SharePoint 2010 in a Citrix environment, and getting the error “ASP.net client-side framework failed to load”.
This indicates that as the Microsoft AJAX framework is not loading and as a consequence the functionality available to the users is severely restricted.
Everything works fine when viewing the SharePoint sites from a desktop PC (both as administrator and not as administrator), indication that the SharePoint server security settings are configured correctly.
Everything also works fine from within a Citrix environment when logged in as an administrator, indication that the Citrix environment is configured correctly.
However a normal user within the Citrix environment gets the above error message.
There are many solutions offered via a Google search which we have tried without success:
• System dates between server and client not in sync;
• Repair .net framework 3.5 SP1, 4.0 etc.;
• The various configuration options which are specific to ASP.net are not relevant when using SharePoint.
Looking forward to some fresh ideas as we have run out.
