Universal Groups in Windows Server can be useful. However, they also have a couple of drawbacks. One downside is that the Universal Group membership is kept in the Global Catalog servers.

This can be an issue when users are logging on in a remote site with slow or unreliable connection. Without the Global Catalog server they cannot logon. By caching the Universal Group membership on a Domain Controller in a remote site you can allow users to logon even when the network connection to the main office is down.<\/p>\n
By default, the cached membership is update every 8 hours. Each refresh cycle can refresh hundreds of accounts at a time (500 accounts to be exact). You can modify the cached Universal Group information in the registry. Here’s the procedure.<\/p>\n
