Knowledge Base article:

Summary

Failed to update the list of domains in this forest to synchronize. User Replicator cannot synchronize any users without knowing which domains to synchronize from.

Causes

This failure occurred because DsCrackNames failed to resolve one of the domain partitions to a valid FQDN. User Replicator doesn't have a list from a previous cycle, and cannot go any further. DsCrackNames typically only fail in Office Communications Server if memory is low on this machine.

Resolutions

If memory is not low and this error continues to occur, the computer needs to be rebooted.
