Cannot connect to tomcat from external browser

I am running Tomcat v7.0.29 on a Windows Server 2003 R2

Tomcat has been working just fine (for months). After a reboot I could not connect to my web pages.

I can start Tomcat on port 8080 (but not from port 80 - but that is a different issue) and connect to the tomcat startup page locally (from the server)

When I try to connect from any external browser I get the message:
"The server at myserver.edu is taking too long to respond."

I am at a loss for what could be causing this.

I tried netstat -na, but that just showed me I have the appropriate ports listening and a few established. (I can post the results of my netstat - but I think that is not the direction to go at this time)

Having exhausted my google search abilities for this issue I now turn to the experts here to assist in solving this issue.

The issue is resolved.

After asking our networking staff if they are blocking port access to the server (which they stated they were not) I then decided to post my question to this forum.

10 minutes after networking did not change anything I can now mysteriously access my tomcat server.
For those having this issue the problem is likely blocked ports via firewall or routers - Check with Networking and give them time to fix what they claim to not have touched in the first place.

If it were easy someone else would have done it :-)
