Hello ... i'm going to be taking out my main DC at some point - so I'm slowly taking out it's services.
I've got an issue with DHCP ...
I have 2 DHCP servers ... let's call the MASTER and SLAVE .... MASTER gave out scope IP's 10>150 and SLAVE gave out 151 > 254 ... this setup has been happily running for many months.
Today, I tried to remove MASTER and make the SLAVE give out 10 > 254.
An odd thing happened, after removing the MASTER DHCP (Add/Remove), the SLAVE was no longer Authorised and could not be until I reinstalled the MASTER DHCP
What am I doing wrong ? Should this of worked ?
(there is a slight chance this was/is a DNS issue, but I wanted to check that I wasn't doing anything wrong with the above first)
