OK, back to programming, as this is not a political blog. Apparently there's some trouble with the .NET Framework Service Pack 1. I personally have not experienced this problem, and I have to admin that it's so obviously weird that I am suspicious that it is in fact a bug. Lots of stuff should/could never have worked if it is. It's likely an install/permissions related bug. That said, here's the details from a recent series of posts on Channel9.
- ASP.NET Forms stop posting back when they have validators on them
- Errors in Event Viewer like "Failed while copying the ASP.NET client side script files to directories under D:\Whatever. Error code: 80070005"
- Copy a PRE-SP1 version of WebUiValidation.js over the one you have in aspnet_client.
- Certainly make sure you HAVE an aspnet_client folder either in that directory or mapped in another VDIR. (This is a common and unrelated problem.)
I'll get the details/diffs on the changes in this file and post them soon.
