where is the netlogon folder
Any changes to the %systemroot%\SYSVOL folder on any DC are replicated to the other DCs in the domain. Replication is RPC based. You can use NETLOGON and SYSVOL to distinguish between DC and member server. If both the NETLOGON and SYSVOL shares exist on a W2K server, it is a DC. When dcpromo demotes a DC to a member server, the NETLOGON share is removed.
