Cannot Browse All Servers

I have 3 W2K (spk2) and 4 NT40(spk 6) servers all in the same domain, mix mode. Also workstations are W2K. Users data are located on NT40 server(NYC211).
Problem; ON NYC211 I cannot map or Browse to this server.
I am able to ping this server by (IP or Name)

The other 6 servers I can map and Browse to.

The error msg I get when trying to browse NYC211 server is “\\nyc211 is not accessible. The network path was not found”.

Any Help,
Thanks
