DHCP Down! ,Tech Journal


Overview:

The focus of this lab was to rectify the theft of the DHCP server by making the fs01 server function as the DHCP server in providing the network parameters to the workstation.

Within this lab I made several mistakes such as forgetting to add the Router to the DHCP configuration and not having it have access to the domain. With some peer help these issues were pointed out and fixed.
