Recipe 11.13 Finding the Bridgehead Servers for a Site

11.13.1 Problem

You want to find the bridgehead servers for a site.

11.13.2 Solution

11.13.2.1 Using a graphical user interface

1. Open the Replication Monitor from the Support Tools (replmon.exe).

2. From the menu, select View Options.

3. In the left pane, right-click on Monitored Servers and select Add Monitored Server.

4. Use the Add Monitored Server Wizard to add a server in the site you want to find the bridgehead server(s) for.

5. In the left pane, right-click on the server and select Show BridgeHead Servers In This Server's Site.

11.13.2.2 Using a command-line interface

> repadmin /bridgeheads [<ServerName>] [/verbose]

The /bridgeheads option is valid only with the Windows Server 2003 version of repadmin. There is no such option in the Windows 2000 version.

11.13.2.3 Using VBScript

' This code finds the bridgehead servers for the specified site. ' ------ SCRIPT CONFIGURATION ------ strServer = "<ServerName>" ' server to target query against, e.g. dc01 strSite = "<SiteName>"     ' name of site to query                            ' e.g. Default-First-Site-Name ' ------ END CONFIGURATION --------- set objIadsTools = CreateObject("IADsTools.DCFunctions") intRes = objIadsTools.GetBridgeHeadsInSite(Cstr(strServer),Cstr(strSite),0) if intRes = -1 then    Wscript.Echo "Error bridge heads: " & objIadsTools.LastErrorText    WScript.Quit end if for count = 1 to intRes    WScript.Echo vbTab & objIadsTools.BridgeHeadName(count) next

11.13.3 Discussion

Bridgehead servers are responsible for replicating data between sites. Instead of all domain controllers replicating the same naming contexts outside of the site, the bridgehead servers act as a funnel for replication into and out of a site. Any domain controller in a site can become a bridgehead server and bridgeheads are designated by the KCC for each writeable partition in the site. You can control which servers are designated as bridgehead servers by defining preferred bridgehead servers. See Recipe 11.14 for more on how to do this.
