To change a subordinate server to a master server by using Windows

1. Open the Identity Management for UNIX management console by clicking Start, pointing to Administrative Tools, and then clicking Microsoft Identity Management for UNIX.

   You can also open the Identity Management for UNIX management console from within Server Manager, by expanding Roles and then Active Directory Domain Services in the hierarchy pane, and then selecting Microsoft Identity Management for UNIX.

2. If necessary, connect to the computer you want to manage.

3. In the console tree, click Server for NIS and view the list of Network Information Service (NIS) domains.

4. Select the domain you want to modify.

5. In the details pane, click NIS Servers, select the Windows server you want to make the new master server, and then click Promote.

	Note
	To open Identity Management for UNIX, click Start, point to All Programs, point to Identity Management for UNIX, and then click Identity Management for UNIX. Only an Active Directory Domain Services domain controller can be promoted to be the master server. When you change a subordinate server to a master server, the previous master server automatically changes to a subordinate server.
