What you propose sound reasonable (I'd leave them attached to a hub though, so that their NIC is active). But highly unrecommended. Upgrade Installs are evil. You would be better off biting the bullet and doing fresh installs with accurate documentation... the documentation would help you in the long run anyway.

We have purchased a new Windows 2000 server. Since our company is small, we have elected to create new accounts on a new server instead of migrating the old system accounts. We allows us to standardize the naming conventions and cleanup the system.. At issue are the old "PDC & BDC". We want to upgrade the systems to "Windows 2000 Server" and have them be only a member servers. We don't want to format and reinstall both Windows NT & Windows 2000 software along with all the other programs. My thought was to upgrade off-line from the WAN, then run DCpromo to change to a member server hopefully discarding any migrated accounts. Then join the new domain. Is this possible or am I looking at a format & Reinstall? Could we reinstall without formatting? Any comments? Clint mailto:cschwab@xxxxxxxxxxxxxxx
