OK, now can i set may Additional Domain Controller for Global Catalog? or is there any problem if set both of my AD server can have global catalog like: 1.click Start, point to Programs, point to Administrative Tools, and then click Active Directory Sites and Services. 2. In the console tree, double-click Sites, and then double-click sitename. 3. Double-click Servers, click your domain controller, right-click NTDS Settings, and then click Properties. 4. On the General tab, click to select the Global catalog check box to assign the role of global catalog to this server. pls help, i don't want to mess with my AD server.

All you need to do is tick the box and job done! There are no problems having 2 global catalogs, infact it should improve your network as long as replication traffic isn't a problem Wizard ICT. Microsoft Certified Professional

The only exception would be if you have multiple domains. If you do have multiple domains, you don't want the Infrastructure Master to be a Global Catalog unless all domain controllers are global catalog servers. In single domains, that shouldn't matter.

i have only one domain say example.com, so is it ok to have two global catalog server?

Not only is it okay, if you don't, you've done something wrong. "Enough, enough bowing down to disillusion! Hats off & applause to rogues & evolution! The ripple effect is too good not to mention. If you’re not affected, you’re not paying attention!"

Thank u, i'll do it then. two global catalog.
