everybody just HOLD ON!!! For the love of GOD, won't you let the poor boy install Norton Antivirus, Corporate Edition?! But seriously, the following may or may not be 100% accurate, but it is acurate in my experience. 1) I attempted an installation of NAV Corporate onto a WinXP_SP1 machine joined to a workgroup, which generated (after installation?) a message informing me that Corp. edition could not be installed on a standalone workstation/non-domain computer. 2) A friend/fellow computer nerd recently attempted to install NAV Pro (non-Corporate) on a compuer running win2000 Advanced server and generated a message stating that NAV Pro could not or would not run on a server. I hope the preceding was helpful. If anyone has had a contradictory experience with either of these scenarios, please flame me. I hate spreading misinformation. K
