Here is our setup:
Remote office ---VPN--> Servers in a data center.
Domain is Server 2008, and DNS/DC's are server 2008.
The remote office has a domain controller / DNS server, then there are 2 DNS/domain controllers in the data center.
The issue is that internet load times are slow for users in the remote office. They are configured to use the DC/DNS server in the office as their primary, then the secondary is the DC/DNS in the data center.
DNS forwarders on the DC/DNS in the office is set to the local ISP's DNS servers.
Page load times are quite slow. Google can take 10 second to fully open when it normally just takes a second.
I believe the issue is related to DNS, but am not sure where else I need to look.
I set my laptop's DNS to the ISP's servers and bypassed the local DNS servers and everything seemed to load quite a bit quicker.
Does anyone know any other spots I can look at to troubleshoot this issue?
Not seeing any errors in the DNS event logs.
