put the unsplit db in the server folder,
do not use a drive letter, open the folder in the full UNC path,
run the split
the front end (FE) should now be linked via the full UNC path (without drive letters)
move the FE to your folder.
give a copy of the FE to all users.
I have a routine to copy the FE to everyone in a list to their personal network folder.
they have a shortcut on their desktop to run their copy.
This way everyone can get updates to the FE and wont know it (nor need to do anything to get it)
