11.11. Disabling Site Link Transitivity or Site Link Schedules

Problem

You want to disable site link transitivity to control replication.

Solution

Using a graphical user interface

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

2. In the left pane, expand Sites → Inter-Site Transports.

3. Right-click either the IP or SMTP folder depending which protocol you want to disable transitivity or ignore schedules for.

4. Select Properties.

5. To disable site link transitivity, uncheck Bridge all site links.

6. To ignore site link schedules, check Ignore schedules.

7. Click OK.

Using a command-line interface

You can modify the options attribute of a site link object using an LDIF file and ldifde, but since the attribute is a bit flag, you are better off using the GUI or VBScript solutions that look at the current value of options and modify it accordingly. ldifde doesn’t handle this type of logic.

Using VBScript

' schedules for all links of the IP transport.
' The code for the CalcBit function can be found in Recipe 4.12
