I just moved my company to a new office. We were on a flat 192.168.16.0 network. We now have multiple vlans. I have modified the IP address of my 2 DC's along with all other servers. I have changed the DNS server settings on each machine to point to the new IPs as well. I am obviously missing something because logging into these servers takes forever.... GPOs do not seem to be running , etc. What am I missing and how can I troubleshoot?
