Windows 7 Home over Ethernet via router

(crossposted from Puppy Linux Discussion Forum as Peter Åstrand 
suggested I should use this list instead)

I have been trying to get PuppyLinux (Lupu 525) to connect to control my 
Windows 7 Home box. The only thing I have been able to use so far is 
TeamViewer who charge a huge amount for any kind of commercial use.

My IP address is the same for both computers and I believe changes when 
I turn on the internet in the morning.

So if anyone can give me a walkthrough of the right commands for 
rdesktop, I'd be grateful.

My guess is it should be some variation of
# rdesktop 192.168.1.72 (the local addres of the computer)
but I get Connection Timed Out

When I use the current IP address I get Connection Refused.

Should I be using some form of computer address e.g. PR-HP, 
PR-HP.MSHOME, or PR-HP.home ?

Kind regards

Peter
