11.7. Creating a Site Link

Problem

You want to create a site link to connect two or more sites together.

Solution

Using a graphical user interface

  1. Open the Active Directory Sites and Services snap-in.

  2. Expand the Sites container.

  3. Expand the Inter-Site Transports container.

  4. Right-click on IP (or SMTP) and select New Site Link.

  5. For Name, enter the name for the site link.

  6. Under Site is not in this site link, select at least two sites and click the Add button.

  7. Click OK.

Using a command-line interface

The following LDIF would create a site link connecting the SJC and Dallas sites:

dn: cn=Dallas-SJC,cn=IP,cn=inter-site 
transports,cn=sites,cn=configuration,<ForestRootDN>
changetype: add
objectclass: siteLink
siteObject: cn=SJC,cn=sites,cn=configuration,<ForestRootDN>
siteObject: cn=Dallas,cn=sites,cn=configuration,<ForestRootDN>

If the LDIF file were named create_site_link.ldf, you’d then run the following command:

> ldifde -v -i -f create_site_link.ldf

Using VBScript

' This code creates a site link
' ------ SCRIPT CONFIGURATION ------
intCost  = 100           ' site link cost
intReplInterval = 180    ' replication interval in minutes
strSite1 = "<Site1>"     ' e.g. SJC
strSite2 = "<Site2>" ' e.g. Dallas strLinkName = strSite1 & " - " & strSite2 ' ------ END CONFIGURATION --------- ' Taken from ADS_PROPERTY_OPERATION_ENUM const ADS_PROPERTY_UPDATE = 2 set objRootDSE = GetObject("LDAP://RootDSE") set objLinkCont = GetObject( _ "LDAP://cn=IP,cn=Inter-site Transports,cn=sites," & _ objRootDSE.Get("configurationNamingContext") ...
