Communication protocol mismatch between client and server

"Communication protocol mismatch between the client and the server"

Both the RTC and the Server are version 6.0.27808.0

Previously it wouldn't find the server at all, then I turned off the firewall on the server and now have this. The other thread with this error the submitter has mismatched versions, so I don't know that upgrading to SP1 is the solution here, but I can try. There was a thread I saw where the user had severe issues after going to 2009 SP1, so I didn't want to try that yet. Any input would be much appreciated.

Edit: Also, in case it matters, I am connecting to the server address 192.168.68.71:7047/DynamicsNAV

The default port is 7046 not 7047

192.168.68.71:7046/DynamicsNAV

ara3n is right.
But, I would like to add one other thing.
Basically message "Communication protocol mismatch between client and server"
when, the NAV version on Client and Server differs from eachother.

I mean, e.g. If SERVER has NAV 2009 SP1 and on Client installed is NAV 2009 Pre-SP1.

Thanks.
