Dumb replication questions

Hi. I'm a bit of a noob to all this and have some pretty basic
questions about replication in a 2000/2003 mixed domain.

I have a DC in a site. I want to find out which inbound and outbound
replication partners it has. I open Sites & Services, browse to the
site, then the server then NTDS Settings and in the right pane I can
see the From Site and From Server. OK - got this I now know which DC
this replicates from. What I want to know is how to identify which DCs
this replicates to? Or is replication bi-directional over that single
connection object?

When I use repadmin /showrepl I get a list of the inbound replication
partners. What command line do I use to identify the outbound - I guess
this is intrinsically linked to the previous question.

In essence my question is, given a server and its site, how do I
identify which other DCs it talks to.

Secondly, I've seen a couple of references on the MS site to a SYSVOL
connection object. See
http://www.microsoft.com/technet/pr...irectory/maintain/opsguide/part1/adogd11.mspx
- step 7 in troubleshooting files not replicating.

Whats going on here? I can't see anything and I've not seen anything
else referring to this.

thanks,
Nic

Replication is technically 1-way (for each connection) but it typically sets
up
the replication between the SAME PAIR for each directory so conceptual
it is ALMOST as if you see two-way information.

Check the partner and see if this is correct. It will have the inbound from
this particular server that mirrors the one you see.

Thanks Herb. I've done this and the paired connection object actually
points to a different DC, but in the same site.

E.G. DC1 & DC2 in site A. DC3 in site B. DC3 has DC1 as From Partner in
SiteA. DC2 has DC1 as From Partner in SiteB.

This suggests to me that the connection objects were manually created?

In the same site it should like this (with 4 DCs):

A<>B<>C<>D<>A

Between sites is should have 1 DC (called BridgeHead Server) with
connections in/out to the adjacent site(s)
E.G. DC1 & DC2 in site A. DC3 in site B. DC3 has DC1 as From Partner in
SiteA. DC2 has DC1 as From Partner in SiteB.

That would be unusual, and practically always WRONG for the same site,
and usually wrong even for different sites.
 
to show inbound replication partners for <DC>:
REPADMIN /SHOWREPL <DC>

to show outbound replication partners for <DC> for which change notification
is used (within the same of or for site links or COs that have change
notification configured):
REPADMIN /SHOWREPL <DC> /REPSTO

to show outbound replication partners for <DC> (wether or not change
notification is used or not):
ADFIND -config -rb "cn=sites" -f
"(&(objectCategory=nTDSConnection)(fromServer=<DN of NTDS Settings of
DC>))" -dn

example:
C:\>ADFIND -config -rb "cn=sites" -f
"(&(objectCategory=nTDSConnection)(fromServ
er=CN=NTDS
Settings,CN=RDC01,CN=Servers,CN=HQ,CN=Sites,CN=Configuration,DC=AD,DC
=LAN))" -dn

AdFind V01.33.00cpp Joe Richards ([email protected]) October 2006

Using server: RDC01.AD.LAN:389
Directory: Windows Server 2003
Base DN: cn=sites,CN=Configuration,DC=AD,DC=LAN

dn:CN=c8b77998-b071-4a4f-a792-afdb6c64556f,CN=NTDS
Settings,CN=CDC01,CN=Servers,
CN=BRANCH,CN=Sites,CN=Configuration,DC=AD,DC=LAN

Settings,CN=RDC02,CN=Servers,
CN=HQ,CN=Sites,CN=Configuration,DC=AD,DC=LAN

2 Objects returned



this will output all connection objects for which the fromServer attribute
is configured with the distinguished name of the NTDS Settings object of the
DC that is used as an inbound partner for OTHER DCs
