"Communication Error
Your Microsoft Dynamics Axapta session is no longer valid.Log off your computer and log on again.if the problem persists,contact your Dynamics Axapta Admin."
I am running both client and server on my system (Win 2k3 RC2 Sp1)
I searched through a couple of forums for the solution and found out that this problem needs a windows 2003 server hot-fix to be installed.The patch/hot-fix is available for download here
Install->Reboot and you are good to go!
