Running NAMED.NLM ver. 6.06.03 (Sep 11, 2007) on NW 6.5 SP7.

I was rebooting everything and once everything was back up I noticed the following error on the DNS server:

critical: Unable to get the object creation-modification with error 35087
error: Unable to get the modification time of DNS server from eDirectory, error value : (result code text not available)

What does this mean?
