I work for a trust of three schools. Each school has its own primary server that provides DHCP, AD, DNS.
At one site we have build and deployed another PC to act as a deployment server and at the moment we take all the hardware to that site to deploy our custom image. The hardware is then returned to its own site and the local configuration is added.
We would like to be able to deploy our image without having to move the hardware from site to site.
Our firewall, one for each site, has been configured to be open on all ports for tcp and udp. This is for traffic between the sites only.
Any advice on further configuration changes would be appreciated.
