The below points may help you sort out the issue:

 

1. Is there any new "automatic" updates on the server? Especially .Net related.

2. Have you checked the log files of respective application?

 

You didn't tell anything about what type of "Authentication" you are using. If you are using "Form Authentication" this post is worth for reading:
