Question : DNS Not resolving correctly over VPN

DNS names such as http://reporting are not resolving correctly over our vpn connections,
The Computers on the remote side of the vpn are all set up using fixed ip address here is an example

IP = 192.168.214.xxx
subnet =   255.255.255.0
gateway = 192.168.xxx.xxx

DNS1 = 192.168.110.xx1 (Our Domain Controller \ DNS controller)
DNS2 = 192.168.110.xx2 (Our 2nd Domain Controller \ DNS controller)
DNS3 = ISPs DNS server
DNS4 = ISPs DNS server 2

they are all set to Append DNS suffixes for our domain
so I would think from this that they should be trying to resolve names from our servers first then from the isp if our servers don't respond(such as vpn being down)

sometimes it will correctly resolve a name, for example today http://intranet resolves and works fine from the remote site I am testing at but http://reporting doesn't work these names are both internal to our main office. yet if I ping either name from the remote side the correct address is returned, and if I do an nslookup I get an error
*** Can't find server name for address 192.168.110.xx1: Non-existend domain
*** Can't find server name for address 192.168.110.xx2: Non-existend domain
but it returns the server name, address and aliases correctly,
but the name won't resolve when I use it in IE7 to try and bring up the web site

I need to Resolve this, Thanks in advance for the help

Answer : DNS Not resolving correctly over VPN

NSlookup issue may because you dont have  a reverse lookup zone.

So the sites your trying to ping are at headquarters?  Pinging by name works from the remote site but IE wont bring them up.
In IE if you put in the IP address does that give you the site?
