You don't give enough information. For instance, use the the 'mount'
command to show the mount for the share. Secondly the message
indicates that the file or directory cannot be found, not that name
resolution is not happening. Thirdly, ping uses DNS not netbios by
default so it is not able to find a DNS entry for 'parallels'. Please
show the DNS entry for 'parallels' and the resolv.conf contents.
Finally, a 'hang' usually indicates a lookup issue. What are the
details for the wins server?

Cliff
