I am able to browse shares and, sometimes, connect my outlook to the exchange server when connected over VPN to my office's LAN. However I am aware my VPN address is in a completely different subnet to that the server is on. (my server is something like 192.168.0.1 whereas my VPN is 5.*)
The problem is exchange and accessing shares can be slow typically at first and exchange often drops out - I think because more needs to be configured on the Windows server 2003 box for domain lookups?
EDIT: I see someone tried to close this question?! Let me rephrase:
How should one configure the DNS lookupzones to allow quick resolution of my local domain from a different subnet?
