How do I remap a network drive on the server to a different cpu across a different domain?

Alright, I have been trying to become more familiar with all  this, I have never actually managed a server before.
I see that the server is on a domain, as [company].local , and all the other cpus are not on a domain, but are all on the same work group.  
Looking at the settings of the other computers I've noticed that I can't browse and find the server through the explore function on my computer.  Nor can I browse while trying to map a network drive.  I can however type in the address of \\server\{file}  and it will map.  
...except for the one computer I was trying to map in the first place.  Even more wierd is that I cannot connect to the wireless router through this same computer either, given the exact same settings as a different cpu on the same wireless network connected to the server.  
If yall have any ideas of how this was set up in the first place I would appreciate it.  I would say don't worry about it too much unless it is really easy.  I think I am going to go ahead and install exchange this weekend.  And that means putting all the cpus on the domain, and wiping out the settings anyway.

If you are goign to run a Domain, then you might as well do it right...  The whole idea of Domain membership is a centrally located management interface, which will allow you to find all members in the domain via DNS, and you can take Netbios (My Network Places) out of the picture..  mapping drives via the DC is also much more streamlined..  you are going in the right direction..

and thanks!

You really do need to set your network up right... best if you get a good book about SBS which you can choose from my recommendations:  http://sbsurl.com/list
