So, just to be clear, are you saying that if you use the same address, 
the Win box reports an error, but if you use different addresses, no 
connection ?  Something like ....

Win :  IP : 192.168.1.1
 netmask : 255.255.255.0
Mac : IP : 192.168.1.1
 netmask : 255.255.255.0

gives an error message, but

Win :  IP : 192.168.1.1
 netmask : 255.255.255.0
Mac : IP : 192.168.1.2
 netmask : 255.255.255.0

give nothing but timeouts ?

Between those two cases, are you changing the IP addr on the Mac or the PC ?

Double check that you didn't set the netmask to 255.255.255.255 on one 
of the systems by mistake.

As well as ping, try doing an   "arp -a" to check if each can see the 
other IP address.
Just for fun,  do a "tracert -d" from each to the other   (may need to 
experiment with the option on the Mac, I can't remember which letter it 
uses for "no dns" lookups).

And do an   "ipconfig" as well on the Win box .... send any (or 
preferably all) of the output (direct to me is OK) from those and I'll 
take a look to see if there's anything unusual.
