I've also started to see this problem on Hosts running 5.5.0 build 2718055.
Turned on advanced logging to lwiod, lsassd and netlogond and seeing the same message mentioned in the original post.
Time is being sync'd with the local domain controller.
Have unbound and rebound the host and run /bin/services.sh restart after doing so.
Anyone have ANY other ideas? Kind of a high priority issue.
