Guys,I would like ask you for a consultation. I have got 3 AD sites, FFL & DFL is 2008.AD Site 1 - contains 2x DCAD Site 2 - contains 1x RODCAD Site 3 - contains 1x RODCWhen I tried to install RODC into Site3 was possible, but then I got error when tried to run replication via AD sites & services console. Replication works withing Site1, between Site1 and Site2, error when try between Site1 and Site3. Says error below.I havenĀ“t found any error in event log pointing to USN rollback ( Event ID2095, 1113, 1115 2103 ), NetLogonservice status is Running.As a test I tried revert in a lab from a VM snapshot one DC and got same error. In the lab I see errors connected with USN rollback, not in production.tried to verify following:DNS configurationipconfig /registerdnsdcdiagrepadmin /showreplrepadmin /kccrepadmin /syncallrepadmin /showutdvec DC dc=forest,dc=suffixAny idea?Petr Weiner.
Detecting USN rollback The challenge is to detect and fix this. KB 875495 is actually a hotfix for pre-Windows 2003 SP1 servers that causes Event 2095 to be logged if a DC sends a USN that was previously known without a change in the invocation ID.
