I'm having a similar issue to other EE users experiencing replication problems in which the prognosis is to demote/repromote the DC that can't replicate. I checked the tombstone lifetime threshold on the PDC using adsiedit tool and there is no integer specified. Does this mean that it is default value of 60 days? The DC that isn't replicating is running Server 2008, and the primary is running 2003. I know the default extended to 180 days at some point, but I'm certain that the problem DC hasn't been able to comminicate w/ the domain for more than 180 days. Can I set the tombstone threshold to unlimited? The DC is mounted on an aircraft, and is routinely out of communication w/ the domain for extended periods of time.
Barring this, is my only option to demote/repromote this DC?
