If anyone reads this and wants to help - thanks !!
I have followed all the instructions at
http://performit.co.uk/network/setup_network.php
All looked OK but trying to explore mshome says
Mshome is not accessible. You might not have permission to use this
network resource. Contact the administrator of this server to find out
if you have
access permissions.
The list of servers for this workgroup is not currently available
Alternately, if someone could give an address or link to where
I can get further instructions, it'd be much appreciated.
Thanks
