This issue cropped up because symantec AV wouldn't remotely update the definitions on a laptop.

Essentially i can ping the laptops IP address but not it's name.
nslookup returns:
*** %server%.%domain%.internal can't find %machine-name%: non-existent domain

We recently had some extra vlans installed for a couple of new wireless SSIDs and new DHCP scopes and DNS zones setup to match.

There are no PTR records in the new DNS zones at all, even though i have configured a dozen or so laptops to a new SSID/vlan

Can anyone advise??
