Notes

To perform this procedure, you must be a member of the Domain Admins group or the Enterprise Admins group in Active Directory, or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.
To open a command prompt, click Start, point to All programs, point to Accessories, and then click Command prompt.
Before seizing the infrastructure master role, use the repadmin command-line tool to verify whether the new operations master has received any updates performed by the previous role holder, and then remove the current operations master from the network. For more information about operations master roles and the Active Directory command-line tools, see Related Topics.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
