Boy that sure does fit as a possibility: "There are several variations of this – but if you aren’t getting *anything* in the logs – start looking at your certificates! More times than not – it is the SSL certificate and you aren’t even getting to ADFS which is why there aren’t any error messages to work with. " Now I just have to educate myself on how to check to see what the sysadmin who is unavailable today configured.

If so, check the ADFS token signing cert., and other things with ADFS.

Sometime overnight the site went down. Now I get a 404.0 error. I've disbaled friendly errors...just get a blank page not even a 404. I've modified the web.config debug=true nothing. Fiddler shows nothing...well not exactly. Fiddler shows a 404 as well. Event logs on server show nothing. I've removed ssl cert and reapplied. Tried accessing the site http nada?? I looked for any updates that were pushed overnight nothing..(they are disabled but I checked anyway). If I browse to http it redirects me https as it should. It prompts for my NT credentials as it should. Downloads favicon and decides it has done all it's going to do. So I am at a real loss as to even getting a clue as to the problem. If someone can help me with some further troubleshooting direction it would be appreciated. Thank You
