basically i have a new domain and web access is slowish and often page not found is returned!
the old domain all is fine.
Old domain pc's gateways point to a firewall which connects to a router and then the internet. This firewall has it own DNS IP's - WEB DNS from our ISP - there is no internal DNS server here.
The new domain is a server 2008 domain setup with 2 DC's - each acting as DNS servers. All computers on the lan point to these for DNS and there gateway is the same firewall as the old domain.
would the DNS be conflicting here? and causing the issues on the new domain?
