Cannot resolve names to ip addresses

Hi all,

I've been trying desperately to move a segment of my location from a crappy old switch into the gigabit age.  Currently I have a student lab that has its own Dell Powerconnect 3024 switch which has a fiber run to another Dell Switch and then has a single ethernet cable going from the second switch into my Catalyst 4506.  The speeds in this lab are atrocious because of this bottlenecking.  The lab is on it's own seperate vlan, because the software they use causes tons of broadcasting.  That vlan is 172.16.0.0/16 while most of the people here are on another vlan 192.168.0.0/16.  
I recently put a HP Procurve 2650 in to replace the Dell Powerconnect that the lab was using.  I used the existing fiber run to connect the gbic port on the procurve to the Catalyst.  After some messing around, I was able to get a connection.  The problem I have now is I cannot ping anything by name.  Pinging by ip address works fine though as does using fqdn.  So xxx.xxx.xxx.xxx and myserver.mydomain.com work but myserver does not.  I can't figure out what is wrong with this configuration.  I have a static ip adress on every machine, with the ip addresses for my dns servers in them.  I need help figuring this one out before I can fully migrate this lab from the old switch to the new.  I don't know if this will help but here is the Vlan config:

interface Vlan172
 description "Foreign Language VLAN"
 ip address 172.16.0.1 255.255.0.0
 ip helper-address 10.10.0.10
 ip helper-address 10.10.0.11
 no ip mroute-cache

If there is anything else I can post that will help out further, please let me know.  

Thanks.

Add "mydomain.com" to the "append these DNS suffixes" section on the DNS tab of the TCP/IP properties of the network connection of the PC's.

didnt even think about that.  It's weird though, once I moved all the computers in the lab over, they all worked fine without me having to change anything.
