Is there any particular reason for using a win2k for domain controller? I have (admittently) a small redundant pc that I rebuilt specifically for a server gateway, also handles the aspect of domain controller as well. Behind this I have my XP Pro system which uses all aspects of the facilities built into the SME box, with local mail distribution as well as handling all the gateway tasks....
All this in an overclocked P133 with 98 Mb SDRAM and a 2.5 gig IDE HDD... 10/100 Intel E-Express Pro PCI NIC.... works a treat
