Enable Universal Group Membership Caching in a Site
In a branch site that has no global catalog server and in a forest that has multiple domains, you can use this
procedure to enable Universal Group Membership Caching on a domain controller in the site so that a global
catalog server does not have to be contacted acrossa wide area network (WAN) link for every initial user
logon.
To enable Universal Group Membership Caching in a site
1. Open Active Directory Sites and Services.
2. In the console tree, expand Sites, and then clickthe site in which you want to enable Universal Group
Membership Caching.
3. In the details pane, right-click the NTDS Site Settings object, and then click Properties.
4. Under Universal Group Membership Caching, select Enable Universal Group Membership Caching.
5. In the Refresh cache from list, click the site that you want the domain controller to contact when the
Universal Group membership cache must be updated, and then click OK.
