Windows 7 machine refuses to accept static IP
Windows 7 machine refuses to accept static IP from Firewall - I have a Windows 7 machine I'm trying to setup with a static IP. The current IP it grabs automatically is 192.168.1.221, which is a dynamic address. I'm trying to make it 192.168.1.98 on the Sonicwall firewall. I've setup every other machine in the office in this manner (Using the MAC address and assigning the IP address) with no problems. .98 is the next available address. It refuses to take it. When I reset the configuration it gives me an "Unidentified/no internet" yellow error and comes up with a 169.254.57.251. If I disable the entry on the Sonicwall it comes back up with the .221 dynamic address.
I've checked every other place I can think of. I've checked to make sure the IPv4 address is set to obtain automatically. I've tried forcing the .98 address through the PC by entering it manually instead of pulling it from the Sonicwall. I've even tried changing the static lease to a different number (.99) with the same results. It only seems happy with that .221 address.
To recap:
PC will only pick up a dynamic IP
Tried to give it a static IP on the firewall and it comes back with a bad IP
Tried to give it a static IP on the computer itself and I have the same problem
I've disabled IPv6
I've triple checked there are no other machines with the .98 address
Any help would be greatly appreciated

Glad to help.
As an aside, it might be worth trying to figure out what the rogue device is. A useful tool to assist with this is https://macvendors.com/ or https://www.macvendorlookup.com/.
Chuck the MAC into one of those sites and they'll tell you the manufacturer of the network adaptor of the unknown device. Might give you some idea what the device is.
