AD – Force SYSVOL and AD replication

Update 17/03/2016: Added a download link for the script.

Recently I’ve been doing a lot of work on group policies and due to the nature of our network replication between our domain controllers is slow. This was causing me issues when testing my changes as they hadn’t replicated to some domain controllers. Knowing that group policies consist of two parts files located in the SYSVOL and a version attribute in AD, I wanted a quick way of replicating my changes to all DC’s within our domain.

Below is a batch file that I written to do this.

Update 17/08/2015 : Now automatically determines all domains in a forest, and forces the KCC to recalculate.


REM Location of the ntfrsutil tool from the File Replication Service Diagnostics Tool.
REM This can be downloaded from:
SET NTFRSUTL="C:\Program Files (x86)\Windows Resource Kits\Tools\FRSDiag\ntfrsutl.exe"

CALL :ForceKCCUpdate

REM Get the forest partition dn without specifying the parent domain.
FOR /F %%p IN ('dsquery * forestroot -scope subtree -filter "(objectClass=crossRefContainer)" -l -limit 0') DO (

	REM Get all parent/child domains from the forest configuration.
	FOR /F %%d IN ('dsquery * %%p -scope subtree -filter "(&(objectClass=crossRef)(nETBIOSName=*))" -attr dnsRoot -l -limit 0') DO (
		CALL :ReplicateDomain %%d


	ECHO Replicating Domain: %1
	REM Replicate SYSVOL.
	FOR /F %%f IN ('DsQuery Server -domain %1 -limit 0 -o rdn') DO (
		FOR /F %%t IN ('DsQuery Server -domain %1 -limit 0 -o rdn') DO (
			IF /I "%%f" NEQ "%%t" (
				ECHO Replicating SYSVOL from %%f to %%t
				%NTFRSUTL% forcerepl %%t /r "Domain System Volume (SYSVOL share)" /p %%f

	REM Replicate AD.
	ECHO Replicating AD
	repadmin /syncall %1 /APed


	ECHO Forcing KCC Update

	REM Force the KCC to recalculate in all sites.
	FOR /F %%s IN ('DsQuery Site -limit 0 -o rdn') DO (
		repadmin /kcc site:%%s
