I have had this problem lingering for a while now.
I have a single domain with 2 Domain controllers(Server 2003) at HQ . I also have four remote sites set up with a DC in each (both windows 2000 and windows 2003). on the rare occurance that the VPN between HQ and the remote sites breaks (ISP outage, Powerloss etc..), the users in the remote sites lose all domain activity. They can't log on, they lose access to shared resources. the desktops are all XP Pro and I'm not sure why they can't even log on with the cached profile.
I have checked a few destops in the remote sites to find out which logon server they are using.
The set logonserver command at a command prompt returns their local domain controller.
This happens for sites with both server 2000 and 2003 domain controllers.
I would like to get to a point where each site can function on a local level even if the VPN connection dies.
Any help is much appreciated.
