We needed to change the IP scheme for a network to allow new equipment to be utilized on the network. The new equipment does not allow the network to remain 192.168.1.0. We decided on changing it to a 10.0.1.0 network.
We did the research on changing IPs on DC, and we completed the IP Scheme change and 1 of the DC will not allow you to ping it by name or IP from any of the clients. You can ping the clients from the server, but you can't ping the server from any of the clients.
We know this is an AD/ DNS issue but we can't resolve it.
What we have done.
We cleared dns cache. cleared arp tables. restarted dns. purged the old 192 a records. verified the new server a records. attempted to use the sbs change ip utility which failed. attempted to force replication between dc which failed-it gave a DNS error.
