Windows 7: Remote Desktop Connection

So I am having an issue with Remote Desktop Connection. First, here is what I am running.



I am using my laptop to connect to my desktop upstairs.

The laptop is a Dell Inspiron E1505 Centrino Duo with 2 Gb of Ram. The laptop is running Windows 7 RC1 32 bit. I am connected wireless to my home network with a Linksys WRT54G router. IP is assigned using DHCP. This computer name is "Lappy"

The desktop is a Core 2 Quad with 8 Gb of ram running Windows 7 RC1 64 bit. This computer is connected to the WRT54G via ethernet. This computer name is "Dustin". I have enabled remote desktop connections to this computer, using the "more secure" option as both computers are running windows 7.

So, the first time I opened RDC on the Lappy, I connected to "Dustin" using my user name. It worked! Nice.
So When I am done I close the RDC window, and go about my business.
20 minutes later I decide I want to connect again, so I open RDC, and try and connect to "Dustin" again, however this time I get an error saying it can not connect to "Dustin" because the computer is off or not connected to the network.(see my attached screen shot). I did not change any settings.

So I run upstairs, and make sure RDC is still enabled on my box upstairs. It is. Nothing has changed. However I keep getting this error. Ok, an hour later I try again, note I still have not changed any settings, and it worked! Ok, awesome.
I go to sleep last night, get up today, try again, and I get the "can't connect" error again!

What is going on?
Please help.
-Dustin

Ok so I just tried using my computers internal IP address and it worked. Go figure. I still don't know why using "Dustin" as computer named worked a few times then stopped. It's working now using internal IP address.

If you just have the 2 computers, you could make a simply hosts file entry in your machine so that it didn't have to resolve the name.

C:\windows\system32\drivers\etc\hosts

I also have a Ubuntu and XP box on the network
