I'll double check that there is definately no firewall issue happening
on the server machine, but I'm 99% certain of it. However, the
microsoft security centre keeps on trying to force its way in, so maybe
it has turned something on that I'm not aware of. If that was the issue
though, I'd think it should have been causing the same issues before I
introduced the router. But, it was working fine before.

Could be a coincidental change.

I'll also check the logs and see if I can find any incoming requests to
my server to help narrow down whether its the incoming request not
getting recieved, or if it just can't send back a response.

The Router's internal MAC is still unique. I can see it on the
diagnostic settings. I'll change it back to the original setting in the
cloning so that the cloned MAC and the internal MAC are the same so I
know that this isn't causing an issue.

If the internal MAC is not the same as the other machine then you could just
leave it as is for now as it shouldn't cause a problem. When the laptop or
the other PC attempts to ping or connect to it the router is "out of the
loop" anyway unless it has some sort of proxy server that they are both
connecting through, so I'm pretty sure you'll find that the XP firewall has
become enabled on the server machine. Also check the TCP/IP settings on that
machine in case something is messed up in the netmask or gateway settings,
but if this had happened then I'd expect the server machine to not be able
to connect to anything other than itself.
