Make Sure your DFSR is working!

This one is kind of interesting. I use a replicated test environment to validate things, it works great. I was using the domains sysvol to quickly copy some text between member servers, however to my amazement I was not seeing the same contents from two different member servers even though both of them validated their security with my domain (nltest /sc_verify:domain)…

It wasn’t until I checked both DC’s that I noticed one member server was seeing a SYSVOL from DC 1 and the other member server was seeing contents from SYSVOL from DC2.

Now, all DC’s have the same SYSVOl contents right?! So what gives?

You may have already guessed it, DFSR issues…. if you know the title didn’t give anything away…

Which lead me to this nice MS support page.

The most important line from it is this…

For /f %i IN ('dsquery server -o rdn') do @echo %i && @wmic /node:"%i" /namespace:\\root\microsoftdfs path dfsrreplicatedfolderinfo WHERE replicatedfoldername='SYSVOL share' get replicationgroupname,replicatedfoldername,state

with this my DC’s reported a state of 2 (well that could explain the diff I was seeing)

which lead me to this nice MS Support page. 🙂 These are usually better than most I’ll admit. I followed the steps on “How to perform an authoritative synchronization of DFSR-replicated SYSVOL (like “D4″ for FRS)”

Until I realized that core doesn’t come with DFSR mgmt tools, even if you install the AD role… So for the most part I skipped the steps stating run “DFSRDIAG POLLAD” cause it’ll fail to run, as it does not exist

Maybe some one out there is smart enough to know the answer…
