May be that the NAV Service Tier is NAV 2009 without SP1?

Hi all,

I have found that Server RTC Version is 6.0.27808.0
and client(s) RTC Version is 6.0.29626.0.

Then why One can connect and another Pc can not ?? :-k

Version 6.0.29626.0 is NAV 2009 SP1
Version 6.0.27808.0 is NAV 2009

Would recommend to upgrade the server to SP1

Yes Sir, I know that !!!
But I'm still in confusion why one can Open & another can not ??

Scenario

I have upgraded the NAV Sql Server Option in my Server Pc to NAV 2009 SP1( from NAV 2009) and installed the Nav 2009 SP1 ( with RTC ) in all of the Client Pcs. I have never ugraded the NAV Server to NAV 2009 SP1 in Server Pc.
