Error: ASP.NET Ajax client-side framework failed to load. Here are some screenshots of the relevant info: Here's the scenario... I compile code locally, view the pages in a browser locally, and it all works fine. Another developer sits down at my machine, logs in with AD account (which create a local profile for his account on http://forums.asp.net/t/1243449.aspx?Error+ASP+NET+Ajax+client+side+framework+failed+to+load+ my machine), and gets these errors when viewing my locally compiled code. He then compiles the same code on my machine again just for a test, but still gets the same errors. Can anyone come up with any good reasons for this behavior? I put a call into MS and they suggested creating a new profile for the other developer with the errors since this appeared to be profile specific. Tried doing that with the same results. Help!

Lisdonk I was getting the the error [‘Sys' is undefined] and [ASP.NET Ajax client-side framework failed to load] in an ASP .NET 4.0 website. After reading and following the post [http://weblogs.asp.net/chrisri/archive/2007/02/02/demystifying-sys-is-undefined.aspx] I found my solution. De ScriptResource.axd [long url] was throwing a 404 server error. This was caused by the fact that the website had an application pool set to .NET 4.0 but the [Handler Mappings] (see Screen dump 001) for the *.axd files where not registered. Even after executing the [aspnet_regiis –i –enable] the [Handler Mappings] where not registered. After re-creating the site, the error was resolved. The screen dump 002 shows the correct handler mappings.

I had some downtime yesterday so I thought, "hey, why not move all of my company's sites from a Win2003 server to a Win2008 server?" Long story short, it's been a sucky 24 hours. I literally tried everything I found on the web: reinstalling the .NET frameworks, running aspnet_regiis –i, etc. and it was the handler mappings all along. Just in case anyone else comes across my comment, here's what the root of my problem was and my particular solution. We have Plesk running on Win2008 on a dedicated server housed at a really big hosting company. When you create sites using Plesk, it apparently does not inherit the mappings from the parent. When I saw your sceenshot, I realized that the handful that were showing up on my plesk-generated sites could not be correct so I hit "Revert to Parent" on those sites and suddenly the nightmare was over and the errors went away. At least it's over until I find out what the fallout is from removing the plesk-generated handler mappings. Thanks again.

Christoph says: June 24, 2011 at 11:28 Thanks for the screenshots, they helped me to check whether everything is registered correctly. However, I solved the problem differently by using a suggestion found on another site: I repaired the "Microsoft .NET Framework 4 Client Profile", and after rebooting the server the errors were gone (Windows Server 2008 R2 SP1, June 2010 Security Patches for the .NET Framework a
