i've been using a shared PC3 and CTB files on a windows XP network with AutoCAD 2000i. So far no real issues have come up. Now i'm creating new PC3 files for AutoCAD 2005. I'm having some issues with the PC3 I setup for a xerox 6050. I think it's the printer more than anything, but the network guy insists that PC3 shouldn't be shared. Any comments for or against shared PC3s?
