Newbie with single phone issue

A phone that also had a PC connected through it was removed from the network and the pc was relocated. Now the phone will not come back on line. The phone is showing an error failed to get boot parameter via DHCP.

network connection is good.

This is all new stuff to me so I would appreciate any assistance that might be available.

Your question makes no sense.

You need to tell us all the information about your system, software versions, network layout etc. What type of phone?
