Heya

Since blogs on the site thumbs up :)

I have the exact same issue with the "is nULL while in ADSite it is <SiteName>. "

Not on the Domain controllers but on one of our Mgmnt machins, and it can not access the DFSroot. Also unbound the IP6 interface, and tone tons of dfsutil/dfsdiag. All rendering in RPC server in unavailable.

Before i unbounded the ip6 interface i did not have ::1 as ipaddress but instead the "deafult" ip6 IP net

Best regards

Does DFSDiag Actually verify down to the file level

Great reading your info on DFS and DFS Replication.

With the replication are files verified as they are copied or is it dependant on later checks.

I checked the Sites/subnets. All the DCs in the domain are in the same site. The only difference is that the two DCs that have the warning are W2K3 and the one that is consistent is W2K8.

does DFSdiag only work on 2008 Server, or can you use it on 2003 server? It seems to be an improvement of the dfsrdiag.exe tool.

TIA,

Hi Brian,

Could you check if the site association of DC by hostname and IP address is the same across all other DCs?

dfsdiag /testdcs gives an error on the last test of "Validating Site Association of <DC> in every DC." It provides the error "DFSDIAG_WARNING - APPL - SiteName form IP - ::1 of <DC> in DC - <remote DC) is nULL while in ADSite it is <SiteName>. This error repeats for every non-W2K8 DC in the domain. I have unbound IPV6 and unchecked the IPv6 protocol, but the problem still is reported. Why?
