TeamCity not working (possibly after Windows Server patch)

Hi

We've got TeamCity 8 running on Windows Server 2008 R2.

Everything has been fine for a couple of years now, but yesterday it stopped working, and now when we try and hit it, it redirects to "overview.html", which doesn't exist (overview.jsp does) and we get a 404 error. Tomcat looks like it's up and running, just not running TeamCity...

There were some server patches the day before (I'm trying to find out which ones) but it was actually working even after the patches anyway, for a few hours anyway. There are no obvious errors in the logs.

While I'm trying to find out more I just wanted to ask if anyone else has experienced this kind of problem before?
