Adprep

[gurvinder.nijjar]

have a windows 2000 native domain running. I have 3 sites and each site
has 2 windows 2000 domain controllers. I want to upgrade to windows 2003.
Firstly I will need to run adprep on the DC which holds all the OM roles.
Would it be best to disconnect this DC from the network and then run the
adprep command. If i get any problems and want to rollback can i just
restore the latest systemstate backup on this DC before i connect it back to
the network.

Some articles suggest this and i just want to confirm this.

no, do not disconnect

instead disable replication

Hi

You need the Schema Master role to perform adprep /forestprep
and You need the I.M to perform the adprep /domainprep

Like Jorge Said disable the replication instead.

how would you disable replication.

Would restoring the systemstate on the DC roll it back to the previous
schema

 

[Jorge de Almeida Pinto [MVP]]

to disable AD replication (not SYSVOL) -->
REPADMIN /OPTIONS <FQDN DC> +DISABLE_OUBOUND_REPL +DISABLE_INBOUND_REPL

In combination with the above to disable SYSVOL replication-->
SC.EXE \\<FQDN DC> STOP NTFRS
SC.EXE \\<FQDN DC> CONFIG NTFRS START= DISABLED (don't forget
the SPACE between = and disabled!)

If you execute this command both INBOUND and OUTBOUND replication is
disabled so that NOTHING comes in or goes out!

If you update the schema and the domain AS LONG AS REPLICATION IS DISABLED,
you only need to restore that particular DC (non-authoritative) using a
backup that does not have the updates to the schema and the domain/sysvol

If you update the schema while replication is enabled the only way to
restore to the state without the schema is to restore ALL DCs in the forest
