Trying to print from my macbook to windows 2003 server

I have Windows 2003 Server R2. I have a macbook with the OS 10.4. I have a wireless router. My macbook connects wonderfully to the internet. The other window laptops connect just fine and when they want to print, all i have to do is go to my computer and in the address bar type in \\servername and press enter. it finds the printer and they are able to print.
My mac will not do this. I have tried the ip address, i have tried the server name.
I have gone to printer utilities. I have been to connect to a server. Nothing will work.

Please help,

Thanks!
