Hi and thanks, I got this problewm solved by a local machine key not even the IIS one, but now the file size which worked fine is now on the fritz, I just for a filure on a 50 MG file, I have set max request in webconfig to max size 2GB, I have set IIS Request filtering to max 2GB, I have removed the entery from the machine.config. I even found the appsettings entries for the upload module which i added and set to 2GB, I have no idea at this point what the problem is. I have never had this probelm with uploads before.

Many thanks for any  help

I found a setting in the upload handler and I also set that to 2 GB, I am still getting the following error
