Port conflict but nothing else is using port 5900

Can't connect and this is the message in VNC Server Information Center: Port conflict preventing direct VNC connections over TCP.  The port on which VNC Server is expecting to receive direct connections is in use by another program or service. For example, it may be that VNC-compatible Server software from a third party is already listening on this port.  Firewall is turned off but added a rule any way.  
Ran this command and nothing else is using port 5900

 C:\Users\administrator>netstat -ano | findstr 5900
  TCP               LISTENING       4760
  TCP    [::]:5900              [::]:0                 LISTENING       4760

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
