Connection Refused

Connection Refused

All of a sudden, I'm getting a connection refused error message in all browsers - both remote and local connection attempts.  Not sure where to look to begin to troubleshoot this error.

The firewall is disabled by GPO on all server machines so I don't think that's what is at play here.  But as a precaution, I went into the firewall settings in control panel anyway to confirm that the firewall was off - and it was.

Any assistance would be appreciated - as I don't want to have to reinstall.  Thanks.
