I have an ongoing issue where laptops that were previously off site come back into the office pickup and IP address from the local DHCP server (site2) but I cannot ping from site1. If i look at the site2 DC I can see that the hostA record in the forward lookup zone. However this hasn't been replicated to the same zone zone in site1. The record does exist however in the reverse look site.
If I look at the replication properties on the site2 DC they are set to replicate to all DNS servers on the domain. However in unsure on where to find the frequency of this. Im assuming its every 15 minutes.
