DFSR Sysvol invalid msDFSR-Subscriber object data


Recommended Posts

Hi All,

I've been scratching my head for the last few hours trying to resolve an issue with a DC.

First a bit of background, I have 3 DCs, all globe catalogues, the server that is having the following problems doesn't have any of the FSMO roles, it doesn't have DHCP or DNS roles although it did a few months ago. All the other servers appear to be working fine. The domain is windows server 2008 R2.

I have the following error in my error log:


The DFS Replication service detected invalid msDFSR-Subscriber object data while polling for configuration information.

Additional Information:
Object DN: CN=Domain System Volume,CN=DFSR-LocalSettings,CN=**DC NAME**,OU=Domain Controllers,DC=**DOMAIN NAME**,DC=local
Attribute Name: msDFSR-MemberReference
Domain Controller: **DC NAME**.**DOMAIN NAME**
Polling Cycle: 60 minutes[/CODE]

AD replication is fine, running REPADMIN /SHOWREPL * /CSV shows no errors and the last success was within the last few minutes and several tests I've done show that replication is fine.

Everything in ASDI looks ok, does anyone have an suggestions on where to look next?

Is this server a Domain Controller? If it is, you really should have dns on it. TCP/IP properties should have the primary pointing to its static IP address, secondary should be pointing to one of the other domain controllers.

as sc302 said, if that's a DC I would strongly suggest you have DNS installed on it as well. Can you even dcpromo without installing the DNS role? :\ Whens the last time DFS worked as it should? Did it recently stop working or has it been done for a month or two?

Thanks for the replies people, looking at the logs it has been doing it for a few months, should probably have realised sooner but hey.

I've reinstalled DNS on the box, DNS is replicating as it should, but I've still got the issue of sysvol not replicating on that machine.

After running dcdiag /q I have the following output:


Some objects relating to the DC **DC NAME** have problems:

Are normal AD objects replicating then, I.E. User accounts?

If your sure its just sysvol thats broken you can rebuild it from one of the working DC's. In 2000+2003 this was done with the burflags regsitry keys but in 2008 there is a new method using ADSIEdit.

AD objects are replicating correctly, new users account etc. all replicate as expected.

I'll have a look at that technet article, thanks.

You are having an issue with replication. Just because you see your AD objects doesn't mean your file objects are replicating properly. Your replication logs should have errors and possibly some in your ad event logs...these logs should have a ton of errors in them.

I am very well aware I am having a problem with replication, I was only answering ]SK[ question about AD object replication. I didn't dismiss your idea to look at he replication logs did I, I was going to have a look at them once I return home.

I'm probably reading to much into it but your post feels like you where attacking me for not replying to you.

This topic is now closed to further replies.

    • I mean, it's fairly self explanatory isn't it? It's part of the reason Apple don't include all features on all supported devices with new iOS releases (another reason is probably a subtle nudge to upgrade sooner), but there's a balance between the remaining features that are added and the impact on performance/battery life on those older devices. There certainly have been times when devices have really received a practical (performance/battery life) quality of life improvement via a software update, but like absolutely every damn app update log out there currently, "Performance and Security improvements" basically mean nothing of real world impacts these days. Just what I've seen of this new interface, the rendering of that glass effect would surely be more complex and intensive than the previous transparency effects, there's no way they couldn't be more efficient. It's probably quite a small impact, otherwise they wouldn't be releasing it, but it all has an impact. Even Microsoft backtracked from Acrylic to Mica material, which is prerendered blur of the wallpaper. All the Acrylic material is rendered live, so has a greater impact, hence why windows use the newer, lower impact Mica material as their base material.
    • This is the reason Microsoft stepped away from Aero for a more subtler transparency. Apple I believe had the perfect balance of transparency and readability, but not with this redesign in its current form. As for people who believe Windows has an 8-bit interface, well, at least you can read stuff.
    • who ever thought this looked good needs to rethink their design credentials.....
    • There's a few here upset Kamala Harris never got the Presidency! lol....
    • Yeah, he identified a whole lot of wasteful spending of US taxpayer money. What's wrong with that? Nothing, unless you had your fingers in the pie of course.
