When on Windows 2003 DC and go to sites and services and go to
[site name]->Servers->[server name]->NTDS Settings
right click on an Active Directory Connection and hit replicate now
I get an error
"The following error occurred during the attempt to synchronize naming
context <my domain name> from Domain Controller <my Windows 2003 DC
name> to domain controller <linux DC at site>:
the server endpoint cannot perform the operation.
This operation will not continue."
Strangely on another site I get what appears to be just a warning as follows
"One or more of these Active Directory connection are between domain
controllers in different sites. Active Directory will attempt to
replicate across these connections. For information about how to
verify replication, see Help and Support."
The difference being this one was auto generated and I had to build
the other one because it had no sites to replicate.
In the event Log I get a whole lot of Event ID 1864 Errors and 1566 Warnings.
Also when I go to sites and services and go to
[site name]->Servers->[server name]
and right click on NTDS and select All Tasks->Check Replication Topology
on my linux DC's I get an error
"The following error occurred during the attempt to check the
The server endpoint cannot perform the operation."
