I have 2 sites, lets call them A and B
At site B they have Windows 2008 R2 server as the DC
Site B is on 192.168.0 LAN
Site A is connected via VPN Tunnel ADSL.
Cisco router at each site.
Site A is on 192.168.1 LAN
PC's at site A cannot join the Domain. Although can ping DC at site B bu IP and hostname.
Can use OWA.
PC can be taken phsyically to site B from A and joined to domain without iuuse. Then returned to site A. Log in then takes 30mins and network is slow.
Have checked all main things like DC is only using itself as DNS etc.
Any ideas guys?
Also does anyone know where i can see a list of exactly what actions are taken when a PC joins a Domain. Not how to do it of course, but what requestes and protocols are fired up in sequence in order so i can find where the steps fail etc.
