To seize the Schema Master role, you must navigate the ntdsutil hierarchy.

1. roles: Enters the FSMO maintenance context.
2. connect: Transitions to the server connections submenu (this is the value provided in your image as a valid truncation of connections).
3. connect to server dc2.adatum.com: Establishes the LDAP bind to the target domain controller.
4. quit: Exits the connections menu to return to the fsmo maintenance prompt.
5. seize schema master: Executes the forceful takeover of the role.

Microsoft Learn (Active Directory): "AD Forest Recovery - Seizing an Operations Master Role." The official documentation specifies the command sequence: ntdsutil -> roles -> connections. However, it notes that ntdsutil is a command-line tool where "the syntax of the commands must be exact," yet it acknowledges that submenus can be invoked via the first few characters.

Official Vendor Documentation (Ntdsutil Reference): Confirms that connections (or its provided variant in the UI bucket, connect) is required to access the server connections prompt before a server-specific connection string can be used.

University of Maryland (CMSC 414): Training materials on "Active Directory Disaster Recovery" which demonstrate the use of ntdsutil roles management, highlighting the requirement to enter the connections submenu prior to binding to a specific server.
