hello everyone, i'm having the same issue like Rfire, that is installing kaspersky av on server 2003, since i already have this av running on xp pro and find it to be the best av around. however, kaspersky labs host on their own site a 'server' trial version for server 2003, but unfortunately after installation it will simply not run - dunno why, it's as if it was asking for a real licensed key although it is the trial version!!!!... odd enough. so that is why i will try to install the workstation edition on 2003, and following Clint's advice , i downloaded microsoft app toolkit and tried to emulate xp pro, but to be honest, could not do it whatsoever. i would very much appreciate if anyone could guide me through emulating xp on 2003 by using ms app toolkit... 10x in avdance ps. btw Rfire, have you managed to install kav on 2003 afterall????
