After further investigation, it looks like Windows 2000 AD schema was previously extended with a prior install of Exchange 2003. The previous w2k admin left the company and no one had the admin password to the new exchange 2003 server. We had to reinstall Windows 2k3 (member server) and Exchange 2k3 (still trying). I also looked at the domain and saw all the schema attributes for exchange. The ldif.err file tells you that the attribute already exist which is why forestprep fails on the e2k3 installation. Do I need to remove all the existing exchange 2003 attributes first before rerunning foresprep or is there another way of doing this. I read somewhere that its virtually impossible to delete schema attributes in Windows 2k once there created. Is this true or is there another way around this?
