Determine manufacturer/model # of computer from MAC address

I am trying to locate a computer that has been used in the past by my organization based on its MAC address.

So far I haven't been able to find this computer as its MAC address doesn't match any of the MAC addresses currently in use on our network.

So are there any online databases that will allow me to enter a Windows computer's MAC address and then get a description of the computer preferably listed the computer's manufacturer's name and model number?

This is definitely a Windows computer most likely a Windows 10 computer.

Very rarely can you do this. You'll most often get the manufacturer of the NIC or network chipset. And that is rarely the same as the computer manufacturer. Almost all manufacturers use Intel, Broadcom, etc, for network hardware, and that manufacturer mass produces chips to the point you can't track down a subset to a computer purchaser.
do you remember if the workstation had a static or dynamic ip before... you could create a DHCP reservervation by mac address and reserve an IP as your preference in the subnet, and when it comes online it could get the ip that you assigned.. unless its static

As mentioned above, you are not going to be able to determine the machine from its MAC - at best you will get its NIC or something close.

Also, depending on specs, you can often change the MAC address manually, which means the lookup tables will mean nothing.  That is generally only done by more technical users (and those 'hacking around') but it does happen.

Was it on the network recently enough to appear in the arp table?
arp -a will return a list of mac/ip

Alternatively run
netsh dhcp server scope show clients 1
On your dhcp server for the ip range to list ip, mac and hostname and search the results for that mac

and MAC addresses are not globaly unique anymore.
dupplicates do exist and are spread as as possible over the globe.
You would have to scour the switches to locate the switch to which ch this system is connected directly.
The remaining is you have to trace to it.
In your situation, you do not see the Mac.
Using the MAC address would identify the maker of the component based on the age it is most likely not be helpful.

If the system is still functional, identifying it from the inside is easier. It could be behind a firewall/nat which prevents its Mac from appearing on resources you checked...
