Mitel phones won't boot after adding 2nd DHCP server (2008 R2)

Mitel phones won't boot after adding 2nd DHCP server (2008 R2)


We're adding a 2nd DHCP server as we're working towards retiring the original. The 2nd DHCP server is Server 2008 R2 and the DHCP configuration was exported from the first one so it has the exact same scope options (Mitel ones are 128,129,130,132,133). The system is Mitel 3300 PBX and 5330 IP Phones. The phone starts booting off Windows DHCP then it sees Option 128 and reads VLAN 10 Priority 6 as it's supposed to but then says TFTP server unavailable and stops reading the Windows DHCP address (192.168.1.x) and below it it says ICP It sits like that for awhile and then keeps rebooting. Oh and yes is the TFTP so I'm lost. Any ideas?
