We get this somewhat frequently with our laptops around the building. Seemingly ramdon, no obvious pattern. A machine will refuse logons, so we'll jump on as the localadmin, drop off the domain, rejoin to the domain and hey presto, ability to login is restored. But every now and again, you drop it off the network and suddenly it can't find the DC anymore. I absolutely despise the lobourious task of reimaging these machines each time this happens, because the teachers like to 'save up' faulty laptops so I always end up with multiple to do at once. I don't suppose anybody has a fix, do they?
