How about altering your mapped drive when you're at work and at home?
SW only needs UNC paths for the toolbox, so if you make your std parts path to just a mapped drive letter (like "P" for parts), then that's what SW will see.
The mapped drive is then changed locally to to work or away.
Thanks for that, but it wouldn't work for the staff who stay in the office and need access to the assemblies, unless I mapped a drive on every machine (IT policy wonks would be an issue)
That might be an option. I'll let you know if I get it sorted.
