Switch Problem + Remote Desktop

[Onedmc]

I have swapped out a router for a switch and now have some issues that I can't figure out.

I can't get remotedesktop connection to work but browsing to the other pc's shares work as does printing.

My current configuration is

ISP -> Router (Cisco) -> Switch (TPlink) -> 3 pc's
Its DHCP from the cisco all on the same subnet

Previously it was
ISP -> Router Cisco -> Router (Belkin) -> 3 Pc's
with dhcp comming from the belkin and it getting it from the cisco.

If i swap it back it works fine.

For a starter question -> Whats going on and why ?

ok I think that I have sorted this myself.

The remote PC is runing windows 7 and I messed about with the firewall settings and got it working.

I figure that the belkin router convinced the pc's that they were all on the same homegroup (I think, as they are not on the same windows domain) so the windows 7 firewall let it through. However the cisco router or router+switch dosn't have such powers.

All very magical and I'm sure there is a bug in there somewhere.

Now to my next question, any idea why WOL dosn't work. Again never had a problem with the belkin in place but never works with the switch in there.
