RE: External Shortcut to Network Drive
As a test, if you move these batch files local, change the shortcuts in the navigation panel of Dynamics GP to point to them local, do they then work?
If so, this would seem to point to a type of network issue being seen between Dynamics GP and that workstation and the bat files on the network drive.
Another thing you could try is setup a shortcut to the batch file on the Desktop of the machine Dynamics GP is installed onto and see if those work.
Otherwise, I can't say we've seen issues with external shortcuts, but maybe the Community has.
Thanks
