Problems mapping a drive across the Internet

I am trying to map a share folder on my PC at work to my PC at home using
\\123.456.789.123\Sharename

1. I can do this locally at the office OK from another PC.
2. I have removed all firewalls from the router and my PC (Yea - I'll put
them back after)
3. I can connect to my work PC from home using VNC and FTP OK
4. I have configured the office PC to reverse NAT all ports to my PC.

So I am fairly convinced that I have done everything OK network-wise

I am thinking that there is a parameter - maybe in the security policy -
that I am missing. I get the error message "A device attached to the system
is not functioning"

You'll need to open up TCP ports 139 and 445, and UDP ports 137 and 138.
Probably better to use FTP

Very, very BAD idea !

NetBIOS over IP should NOT be used over the Internet. There are too many BOTs ready to
exploit such a configuration. Everything from the BugBear worm to SDBot.

This should ONLY be done through a VPN !

Even VNC vulnerabilities have been exploited.
