There are issues with Network Browsing seeing Windows workgroups, usually to do with firewall settings at either end.
First of all make sure you can ping the other machine.
Even if browsing doesn't work you should still be able to connect from linux by
Code:
smb://winmachine/sharename
in Konqueror. Depending on the security on the Windows machine it may either connect you or ask for a name and password.
Both SuSE 9.2 and Windows XP by default activate firewalls - you need to allow the Windows browsing protocols through. These are ports 137 to 139 and 445 TCP and UDP (not sure exactly what combinations are used).
On Windows if using the Windows firewall if you allow file and print sharing it will open the right ports and on SuSEfirewall2 ticking Samba server should work, however, I have had problems in the past with a single NIC - even specifying the correct ports in the Expert settings.
You can check the firewall script in /etc/sysconfig/SuSEfirewall2 to make sure that it's setting the right things - it's pretty well documented.
You can always try temporarily disabling the firewall to see if Windows browsing works while you're sorting out the issues.
If it is the firewall blocking it you can have a look at the log file. You need to open a shell and su first, then
Code:
cat /var/log/messages | grep DROP
will give you all the packets dropped by the firewall.
