General question about protocols on servers

[Chr1sUK]

I have recently read that there are 4 particular protocols that cannot run on a server at the same time. Dispite having done networking for the past year, I was not aware of this per se.

I understand that two of these protocols are DNS and DHCP.

What are the other two? FTP and NNTP by any chance?

Why is it that these cannot run on one server?

TIA.

You can definitely run DHCP server, DNS server and an FTP server on the same physical server. Not tried running a NNTP server but I'd be surprised if you can't.

If it doesn't leak oil it must be empty!!

obviously I have read wrong then....

Anybody else got anything to add?

TIA.

Perhaps it meant that you can't run the other servers on a server that had a DHCP allocated IP address as it could change if the machine is rebooted. Though don't see why you wouldn't allocate a static address to a server in the first place.

It really depends on the amount of traffic the server is going to receive. If you set-up a DHCP server for 300+ devices and set the lease time to be 1 day, that server is going to be one busy server. If you then put DNS on that server as well, you may run into DNS issues if that server is busy.

We have 280 workstations in our environment and we run with 1 dedicated DHCP and PRINT server, 3 domain controllers and 3 DNS servers.
