Replication

I have two W2K servers, one of which is the DC. I have built a new W2K3
server to replace the W2K DC. While conducting domain/forest inventory, I
first ran a "repadmin /showreps, which seems to display successful
replications on both servers. I subsequently forced a replication on both the
W2K servers which SOMETIMES gives me either one of the following results
depending upon the time (15-30 minutes apart) the force replication is
initiated:

- "Active Directory has replicated the connections"

OR

- "The RPC server is unavailable. This condition may be caused by a DNS
lookup problem..."

I don't want to proceed with the addprep and DCPromo of the W2K3 server and
be unsuccessful until I know that the latter error above is non-fatal. I have
struggled with this project for months until I had to place it on the
backburner to tend to higher priority projects. I have recently resumed
working on this project and need some assistance. Any light you can shed on
this will be greatly appreciated

You really should have at least two DCs whenever possible.

There is something odd above you need to clarify -- you state you have ONE
DC, in which case there is nothing replicating.

Replication occurs primarily between DCs of the same domain, to a lesser
extent
(not much in fact) between DCs of the same forest.

You cannot complete the ForestPrep or ADPrep until you have full
replication.

This could be a problem if you have ever (in the past) had another DC which
was physically removed from the network but never officially removed as a DC
(i.e., by DCPromo).

If this is the case you must clean up the AD with "NTDSUtil metadata
cleanup".

Just Google for this or something like the following:

[ NTDSUtil "metadata cleanup" remove DC | domain ]

You cannot complete the ForestPrep or ADPrep until you have full

This could be a problem if you have ever (in the past) had another DC which
was physically removed from the network but never officially removed as a DC

If this is the case you must clean up the AD with "NTDSUtil metadata

......................... SO_DNS failed test Connectivity

So you failed at least the DNS in Site SO_DNS.


Also in a single domain forest ALL of your DCs should be DCs, especially
if you are swapping out DCs.

Remember to transfer the Single Master Roles (aka FSMO) to the new DC
before you remove the old one.

Plus every machines needs to know about the new DNS (and WINS Server
if any) before you remove the old one.
 
Herb,
I ran the Netdiag /fix on both DC's and followed-up by forcing
replication on both servers successfully and lastly I ran the DCDiag /c on
both servers. The results are pretty clean (all other test passed) but I
would like your opinion on the printer errors I received when I ran the
DCDiag on both servers. Are these printer errors fatal? Also I would like
your thoughts on the LDAP error received when I ran the NetDiag /fix on
Server "A". I believe we're almost there. Thanks again for your help.

Herb,
I ran the Netdiag /fix on both DC's and followed-up by forcing
replication on both servers successfully and lastly I ran the DCDiag /c on
both servers. The results are pretty clean (all other test passed) but I
would like your opinion on the printer errors I received when I ran the
DCDiag on both servers.

They are nothing to the DC "as a DC".
Are these printer errors fatal?

And may be nothing at all (anymore):

DCDiag reports errors appearing in the System Log -- it will do this forever
until the System Log is cleared.

So after taking any action you deem useful (or recording the error for later
review), clear the system log and wait to see if the "printer error"
returns.

If not, then DCDiag will have nothing to report. DCs have no dependence
on printers (except as ordinary clients would use a printer.)
Also I would like
your thoughts on the LDAP error received when I ran the NetDiag /fix on
Server "A". I believe we're almost there. Thanks again for your help.

That isn't really an "LDAP error" but rather another DNS problem:
LDAP test. . . . . . . . . . . . . : Passed
[WARNING] Failed to query SPN registration on DC
'so_dns.so.co.contra-costa.ca.us'.
