First, all problem machines are Windows XP Pro SP2/3, are correctly registered, have the correct CASubject registry info and are across a wan (not on the same site or subnet as the primary server). Second, within a subnet, the problem is prolific and random (can't predict which machines will be effected). Computers with a static IP, like satellite servers, never fail and computers at the site of the primary server work properly. Freshly registered or reregistered computers are easily remoted into, but may go bad. Once the UTC error appears, the computer can only be "temporarily" fixed by reregistering. Windows remote desktop has yet to fail. Windows boxes time sync with "time.windows.com." The primary server is SLES 11, but I don't know where it gets its time from, maybe our Netware 6.5 server (yes we're aware of OES). We're on ZCM 10.3.1, can't update to 10.3.3 don't have rights, but we're working on it. Satellite servers are assigned all roles. We have a hardware appliance, Sonicwall TZ-170, issuing DHCP on each subnet, except at the primary server site, where it's issued by a Netware 6.5 server.

Aside from time sync stuff and the 10.3.3 update, are there any other places I should be looking. Might updating to Zen 11 fix this?
