I'm working at a client's location with a single domain computer and I'm adding workstations to the domain for the first time. (For whatever reason they never used the domain for user authentication). Anyway, once I join a computer to the domain it will start to lose its time sync with the domain controller by a couple hours. I can switch the time back but it will invariably lose time. I'm not certain if the time is simply stopping or if its resetting. Oddly enough, when I check the domain server clock its time is accurate. Its only the PCs I've added to the domain that are having this problem. All non-domain member PCs are showing time fine. Also, I see no errors in the PC Event Logs.
Any thoughts on where to look to resolve this or some troubleshooting tips? I've setup many a domain and added many a domain PC but I've never seen this.
