I am having an unbelievably bad time trying to get my WinXP machine to
see my Redhat 7.3 Linux box in any way. I set up Samba 2.2 by
explicitly following the instructions at
(Darn URL filter).linuxorbit.com/howto/sambahowto.php3 and it still doesn't
work. I'm thinking that my router is the problem. It's a Netgear
RP614v2. I have it hooked up to my cable modem and my Win and Linux
pcs each plugged into a port on the router.
When I double click on the workgroup from windows, all I get is the
error "'Workgroup' is not accessable. You might not have permission to
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."
I did set up the same username and password on both computers, and am
logged in as that user on the windows box when I attempt the
connection.
Thanks.

Check your firewall rules. As root run:
iptables -L
netstat -nlp

and post the output.

Thank you for your reply, David.
Here it is:

iptables -L
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed
iptables v1.2.5: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Any clues on this?
Do I need to dump RH7.3? Or something else????

Hmm. I am not sure about the iptables part, but something is definitely wrong with iptables. Did you make any changes to your kernel? Can you post your smb.conf file? Can you ping to and from the other machine?

Sid,
I can ping the RH machine from the XP machine by IP, but not machine name.
I can't ping the WinXP from the RH machine, but I can ping www sites.
I don't believe I did anything to the kernel. For a long time the HOSTNAME was showing up as localhost@localhost.(localdomain?). So when I'd log in I'd get something like barry@localhost@localhost. I finally got that changed,
