Hi,
I'm having a little difficulty restoring file replication between two of our servers. I'd appreciate some thoughts...
Background information:
We have got two replication groups (with two servers in each totalling 4 different servers. E.g. Group 1 - Server A <-> Server B & Group 2 - Server C <-> Server D.
We haven't made any major infrastructure changes or configuration changes recently but group 2 has simply stopped working. This is what I've tried so far:
Deleting and starting again
Connectivity checks:
pings by IP resolve
pings by name resolve to IPv6 (I wasn't aware we were using IPv6 in our infrastructure)
nslookup resolves and lists all IP's inc. IPv6
RPC ping resolves ok, output: RPCping completed 1 calls in 1ms 1000 T/s or 1.000ms/T
All windows firewalls are off and the replication is within the same LAN and the other group is working fine.
Portqry on ports TCP 139 come back as not listening and 445 TCP is listening.
The error I'm seeing in the Event log are:
Event ID: 5002
The DFS Replication service encountered an error communicating with partner Server-A for replication group Rep1.
Partner address: (This is correct)
Optional data shows a wins of: Server-A
Partner IP Address is listed as IPv6
The service will retry the connection periodically.
Additional info:
Error 1825 (A security package specific error occurred.)
Connection ID: X
Replication Group ID: Y
DCDIAG is coming back clear on the DC and repadmin /showreps is also clear.
Browsing across the network to these machines works ok.
Earlier this week, I recreated the replication group and did manage to get one half working but I couldn't get the replication working both ways. I tried recreating the group again from scratch and I'm now getting:
"Some servers cannot be contacted. Do you want to use them anyway? The server's OS version cannot be retrieved. Access is denied"
Can anyone possibly shed some light on what else I could try please?
Thanks in advance
Mark
