DHCP Snooping

I am trying to configure DHCP snooping on our HP 2530 48 port switch.  I have added the authorized DHCP servers and enabled DHCP snooping on the desired VLANs.   The issue is when I reboot a computer on the network it does not get a DHCP lease.  As soon as i disable DHCP snooping the computer gets a lease. Any help would be appricated!

Re: DHCP Snooping

We're using DHCP snooping on a load of 2530 switches without any problems. Do you see anything in the switch logs about DHCP traffic being blocked? Here is the config we use.

dhcp-snooping
no dhcp-snooping option 82
dhcp-snooping authorized-server x.x.x.x
dhcp-snooping authorized-server y.y.y.y
dhcp-snooping trust 49-52
dhcp-snooping vlan 1-999
