Its that easy? ya I know where to set GC option, I have around 13 DC but one domain, and the document I read said you can have only one GC per domain, so I have only one GC and didn't tick the GC option on another server.(thought something will go conflicitng with the current GC). Replication is set between servers but it has nothing to do with being a GC I assume. thank you for the valuable info -----Original Message----- From: Dolly Bareqet [mailto:dolly@xxxxxxxxxxxx] Sent: Tuesday, December 21, 2004 12:25 PM To: [ExchangeList] Subject: [exchangelist] RE:Exchange 2000 problem http://www.MSExchange.org/ When you have two DCs in your domain, you can configure replication between the two. In AD Sites and Services expand rhe server. Right click on NTDS settingsand select Properties on the General Tab check the Global Catalog. Do it on both DCs.
