Dear all,
Firstly thanks for your time in considering my query.
We noticed something in Sites and Sites a week or so ago, and have wondered if this is expected behaviour or not.
Problems:
1) Servers in Site 1, and Site B don't have automatically generated links between them
2) All RODC's only use Servers in Site 3 as their Bridgehead Servers, and won't connect to Site 1 unless we move the cost to Site 3 up
Overview:
We have a single 08 R2 domain, with 08 R2 domain and forest functional level.
90 sites: 4 sites contain RWDC's, one site is empty (more on that later), 85 Branch office site contain one RODC each.
RWDC Sites:
Site 1: 3 RWDC DC's - We consider this a hub site as it's a Datacentre
Site 2: 2 RWDC DC's - We consider this a hub site as it's a Datacentre
Site B: 2 RWDC DC's - There to support a large office
Site S: 1 RWDC DC's - There to support a large office
RODC Sites:
Each RODC site has it's own connection to an empty site (let's call it Site H, for hub), and there is one connection from Site H to Site 1 and one connection from Site H to Site 3.
Site Links:
1 <--> 3
3 <--> S
S <--> B
B <--> 1
H <--> 1
H <--> 3
RODC Site 1 <--> H
RODC Site 2 <--> H
RODC Site 3 <--> H
...
All Costs are 25, all Replication Intervals are 15
'Bridge all site links' is enabled. All connections are automatically generated. There are no preferred bridgehead servers in the domain.
Troubleshooting so far:
repadmin /kcc * - all successful
repadmin /bridgeheads /verbose - shows no bridgeheads between Site B and 1, and visa versa
dcdiag - no errors on any RWDC
repadmin /istg - ran on servers in Site 1 and Site 3, both show all sites and an RWDC ISTG server (and a few RODC's (strangely?))
I feel like I'm shooting in the dark with my troubleshoot as I don't have enough experience to know what to look for in repadmin or other commands to use to methodically troubleshoot this/confirm this is working as expected. If this is a problem at all!
Thanks again.
