This should be an easy problem to identify, since Ledger is just complaining that there is no GL data in the Folder it is being asked to open. GL data files begin GL* and should be viewable with Windows Explorer. It expects to find a basic set of files (the company profile and chart of accounts for example) when it opens.

Log in as the Server Admin.

First, check the properties on the Ledger shortcut to verify the Folder it is opening. The Folder name will follow the /d: parameter. Make sure that the extension is correct (after the /e: parameter).

Use Windows Explorer to open the Folder. Use Notepad to create a file "TEST.SAM" and save it (you'll need to change the file type to "All files", otherwise Notepad will save the file as "TEST.SAM.TXT".) Delete the file.

This should all work without error.

Now log is as the regular user on the workstation. Repeat the process above. It should also complete without error.

Report back your findings. I expect the User login to fail at some point in the process.

If you feel that the user has been set up identically, then delete the User profile from the server and set it up again. Repeat the above test.
