Hey guys, nother question for ya. I am in a bind and need to install WIN NT on a machine and make it my Backup Domain Controller. I will be installing NT from a brand new (blank) hard drive. My question is: If I configure this server and install it as my BDC, will this have any affect on user accounts at this present time? I dont want to config it to a BDC then have it take my entire network down for the day. In a company of about 150 employees, that's the last thing would want to do. Thanks for your help.
