Hi giteshs,
I'm sure the issue is about the installation of the nrtap driver on your X64-2003, but I didn't figure out why, since there are various factors.
One more thing you may want to check is the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce , it must be there. If not exists, please add it.
See
viewtopic.php?f=6&t=1089&p=1717&hilit=tapinstall+exe#p1717You can try to manually install the nrtap driver and see if you can get more information.
To do this, you can copy the folder ZebraNetworkSystems\NeoRouter\Driver\* from the win7 x64 box to the X64-2003 and run the following command:
tapinstall.exe install nrtap.inf nrtap
If you just want to setup a server , you can choose to install the NR server (only, without nrclient) by choosing the checkbox in the installwizard.
Thanks,
