all computers on Network 5 apart from one machine

[richiwatts]

I have all machines apart from one connected to a switch. The switch and the spare computer are connected to the Gateway.

All machines have fixed IPs
192.168.1.111 - 119
255.255.255.0
192.168.1.254

We also have a NAS connected to the Switch.
The new computer connected directly to the Gateway can't see the NAS.

Also all the other machines that can see the NAS have network name
Network 5

But on the new machine it is only called
Network

How can I get the new machine to be part of Network 5?

Well, there's a lot of info I'm going to have to assume and make speculation on as you don't give specifics on gateway model and O.S. on machines.

So a couple of things you need to look at and answer.
Can you ping from the "spare" computer to the others that are directly connected to the switch?
If yes, then change the name of the workgroup to Network 5 on the spare. If you are on a Active Directory domain, then you need to join that computer to the domain network.
If no, then chances are your gateway/router port that you have that spare plugged into is on a different security/zone than you LAN port you have the switch plugged into. Again, don't know the model of gateway/router to offer you more info.

Respond back with answers to above to help further.
