Anyone noticed what happens when you open a mapped drive? Try it, run a program/batch/etc from it and look at the loverly "WARNING:- Death to all those who run this program" box that appears. Its causing hell for all those like me who have batches run on startup for workstations (they are on mapped drives, thanks to my MagicCards (hardware deepfreeze)). anyone who finds a secure work around, please let us now! damingo
