May consider vmware suppose but never Virtual PC. This system was explained to me in detail by a Unix administrator but I never got time to write it down. Will track him down & post the info.
A folder or drive with rights heavily restricted so all downloaded software, etc can be placed there and checked prior to use. Rights are normally restricted to stop any programs being run by accident, etc.
I am trying to setup peer to peer backup using Veritas without much success. Has anyone achieved this? It says it can but I can find no information about the settings required in XP and software configuration. Cheers
