I have a network of 25 workstations and 1 server that is acting as the DHCP and DNS server. I've noticed on some of my workstations that when I use nslookup, the IPs and hostnames do not resolve. When I enter nslookup hostname, it returns my server's IP (which is correct), the hostname of that workstation, and an IP address.
When i enter nslookup and the IP address that it just stated belongs to that machine, I still get the correct DNS server IP, but I get a completely different hostname. Example of what's happening (changed IPs and hostnames):
Address: 192.168.100.250 (server; this IP is correct)
Address: 192.168.100.225 (IP that NS lookup says is issued to MYWRKSTATION001
Address: 192.168.100.250 (again, the server IP is correct)
Address 192.168.100.225 (now the lookup is saying that this IP belongs to a different machine)
I have scavaging enabled on the server. All the workstations are set to automatically detect the DNS server, which they seem to be doing correctly. I believe this is causing some problems with my network. If anyone can steer me in the right direction on how to fix this, it would be much appreciated. I'm just a beginner with DNS, so please go easy on the instructions :)
