Hi All, I am doing Exchange server installation for the first time. I had one Exchange server machine(named XYZ) in a domain. I formatted that machine and installed and gave the machine name as ABC and installed exchange server again on the same domain. The problem is that the domain has a built in administrator account for the previous machine i.e.XYZ and when I installed exchange server newly that user is imported automatically. When I open system manager, all my public folders shows only that user in members of tab in their properties. They do not show the users created for the new exchange server(ABC). I just wanted to know if there is any way to remove that old administrator account from the domain controller or how can I resolve this problem. Help Please.... -Varsha __________________________________________________ Do You Yahoo!? Yahoo! Finance - Get real-time stock quotes http://finance.yahoo.com
