There is a bug I'm seeing with AD replication across other sites on my WAN. Once we've disabled the daylight savings time AD replicates without a problem. However if I uncheck it on my DC's it replicates that to my clients, now my clients clocks are off an hour and some cannot log into the domain and wreaks havoc on Outlook Meetings, setting them off an hour. In order for this to work I can set a different GMT to make this work. What would be the impact of setting the improper GMT on my Win2K AD domain, Outlook clients and AD replication? When I synch to an outside SNTP server ( US navy )it defaults back to Checking the Daylight Savings Box. Is there any time client software that I can use that allows me to disable the daylight savings feature?
