FRS (File Replication Service) is used to replicate Scripts and Group Policy in Active Directory. FRS is dependent on Active Directory Connection Objects. FRS is multimaster technology meaning any domain controller can make changes to the Replica Set. This tip explains a simple mechanism you can use to make sure the FRS is working or all the domain controllers are receiving the changed file. In this example, we assume we have four domain controllers: RootDC1, ADC2, ADC3, ADC4.
- Create a Text file on each DC at the location: %SystemRoot%\SYSVOL\SYSVOL\Domain_name\Scripts
- On RootDC1, RootDC1.txt
- On ADC2, ADC2.txt
- On ADC3, ADC3.txt
- On ADC4, ADC4.txt
- Wait for at least 5 minutes
- Log on to each DC and check all the four files you created.
If all DCs have the files you had created in its Netlogon share then that means the FRS is working properly. If you see two or three files but not all the files on a DC then check for which DC it hasn't received the file and then troubleshoot using the more advanced tools available at Microsoft site.
