Hi experts,

I have two forest level domain controllers and two at domain level ie
1st FDC > Schema owner and GC
2nd FDC > Domain Role owner
1st PDC > RID , Infra, PDCe

what happens when i change the time on my 1st FDC? Will the rest of the DCs synchronise with the FDC? How about remote site DCs?

They will only sync if you have the FDC setup as an NTP server and then point the other servers to sync time with the main server in the time/date properties.

The PDCe machine is the "master" time server, other DCs will sync to it.  Time skews of more than 5 mins are outside of what Kerberos allows, and will casue replication to fail on the DCs.

What are you trying to do here?

Hi Malmensa,

The following is our organisation's domain setup:

  |__ production.company.com.bn

Two servers (FDC1 and FDC2) in company.com.bn Forest-level domain
Two servers (PDC1 and PDC2) in production.company.com.bn Domain-level domain

i ran the netdom query fsmo on FD1 and PDC1, and the results are as follows:

Schema Owner                                  FDC1.company.com.bn
Domain Role Owner                            FDC2.company.com.bn
PDC role                                              FDC1.company.com.bn
RID Pool manager                                FDC1.company.com.bn
Infrastructure Owner                          FDC2.company.com.bn

Schema Owner                                   FDC1.company.com.bn
Domain Role Owner                            FDC2.company.com.bn
PDC role                                              PDC1.production.company.com.bn
RID Pool manager                                PDC1.production.company.com.bn
Infrastructure Owner                          PDC1.production.company.com.bn

All servers are time sync but are 20 minutes earlier that the "actual" time ie the actual time is 9:00am whereas the servers are 9:20am.

Will all the servers sync with FDC1's time automatically once i change it on the time/date properties? What are the gotchas that i should look out for?

It sounds to me like the only thing you would need to do is to update the time on the NTP server.  The remaining machines will then sync up to the NTP server.
