Question : Citrix Provisioning Server, Cannot Find vDisk

Here is my situation. I am building a brand new vDisk on provisioning server. I made it private and assigned it to a physical machine and told it to boot from hard disk. I then PXE boot the machine (a dell 2850) it sees the provisioning server and that it supposed to get a vDisk, but after about 20 mins of sitting at the PXE screen it finally comes up and says cannot find vDisk. Then boots to the local OS. If I add the same vDisk to a VMware VM it boots up perfectly fine. Any ideas?

After some time on the phone with Citrix support we actually had to turn portfast on the cisco switch port and it worked fine.
