I have a major problem, last friday all my reports failed and i mean ALL.

I have two problems, when running a report that's been written in Visual Studio 2005 in asp.net it asks me for a username and password to log on then it doesn't display the tool bar coreectly.

So thinking it was a permissions problem i rebooted both the web server and domain controller. But still nothing is running.

I have even tried created a report on my machine and that doesn't work (toolbar doesn't display) and if the report has a date parameter the calender button shows as a red X, and when you click on it nothing happens.

Only thing i can think of that's changed is the group policies for both domain controller and domain. Could this be the problem.

Any Ideas, i really really really need this working ASAP.
