I am looking to upgrade AD from W2008 SBS to W2012.
There are are 2 AD controllers - SBS2008 plus W2008 R2 at another site, permanently connected by a VPN.
I have run the command Dcdiag /v /c /d /e /s:DCName.
Part of the output says (note I have removed direct server and domain name references):
" Starting test: VerifyEnterpriseReferences
The following problems were found while verifying various important DN
references. Note, that these problems can be reported because of
latency in replication. So follow up to resolve the following
problems, only if the same problem is reported on all DCs for a given
domain or if the problem persists after replication has had
reasonable time to replicate changes.
 Problem: Missing Expected Value
CN="servername",OU=Domain Controllers,DC="domain name",DC=local
Base Object Description: "DC Account Object"
Value Object Attribute Name: msDFSR-ComputerReferenceBL
Value Object Description: "SYSVOL FRS Member Object"
Recommended Action: See Knowledge Base Article: Q312862
Now I believe this refers to missing FRS Objects and FRS attributes and I need the file "Topchk.cmd" to parse the output of "NtrfsUtl ds" command. It just isn't clear to me where I get "Topchk.cmd" from and why its access appears to be restricted?
Thanks for any help
