Where are the GCs located? I believe Exchange Enterprise Servers is created by the first Forestprep. Exchange Domain Servers is created by the first Domainprep in a domain. I'm most interested to know if they are universal groups, local groups...etc. Please don't delete the thread from the message. I already don't see the original problem report. -----Original Message----- From: Danny [mailto:nocmonkey@xxxxxxxxx] Sent: Thursday, February 09, 2006 8:58 PM To: [ExchangeList] Subject: [exchangelist] RE: Exchange 2003 domain prep fails on a 2000 server - Error 0XC0070560 http://www.MSExchange.org/ On 2/9/06, Michael B.
