hrm...
try Start -> Run -> "\\<<IP OF YOUR SAMBA BOX>>"
without the <<>> stuff of course :-D
the thing why swat and webmin doesnt work could be:
1. localhost is unknown (look into /etc/hosts for a 127.0.0.1 localhost localhost.localdomain etc line)
2. hostname of webmin/swat misconfigured (when u try to connect to localhost and the webserver of webmin is configured to use for example foobar as hostname there must be a ip for the name foobar in the /etc/hosts too)
3. look if your loopback device is up (/sbin/ifconfig and look for a "lo" section)
look with netstat if the ports 901 and 10000 are listening (netstat -na)
what is the error message that u get when u are trying to contact local host on port 901 and 10000? connection refused, timed out...
whatever
information!
