sysvol folders out of sync in Active Directory site

I have 3 x 2008 r2 domain controllers on one AD site. On 2 of the domain controllers the sysvol folders are out of sync (the 3rd is in sync with other DCs on other sites across the domain). There are also many errors in the FRS event log.
Group policy has been badly effected.
What is the best way of getting the 2 x DCs to sync with the 3rd correct Dc.?

Any help would be greatly appreciated.

I have had this problem before.  I used the following command on all of my DCs.

wmic.exe /namespace:\\root\microsoftdfs path DfsrMachineConfig set MaxOfflineTimeInDays=365

Just type that into cmd/PS and maybe give the servers a restart.
FRS is for Server 2003 I believe and is not relevant in 2008.  I get the same errors, but I just ignore them.
Hope that's of some use to you.

I have seen windows firewalls cause issue with this replication if they are too restrictive, worth checking if these are on and if so disabling temporarily to see if these repairs the issues.

Sorry for the amount of time passed. Another SysAdmin demoted and then DCpromo'd both servers before I had chance to investigate.
Many thanks for all  your suggestions anyway.

Apologies, I shall close the question.

I maintain a network with three Windows 2008 r2 DC's and at times we have replication issues also. Here are commands I use to manually kickoff the replication process to make sure it has run properly.

Copy each of these commands one at a time into notepad and save them as a CMD file instead of a text file (on the desktop of one of the DC's,

Title: SyncAll.cmd
repadmin /syncall
pause

Title: Queue.cmd
repadmin /queue
pause
repadmin /replsummary
pause

Title: Showall.cmd
repadmin /showrepl
pause

After saving them on your desktop, run each of them. They will pause before closing showing you if the replication request was process properly.

Hope this helps!
