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
