My network is as follows - Static IP addresses:

Gateway: M1122 192.168.1.254
Wireless Router: DI-524 192.168.1.1

Workgroup: PRODSYS
ADVANTAGE computer: 192.168.1.2
dell computer : 192.168.1.4

Subnet Mask : 255.255.255.0

Both computers list PRODSYS as the Primary DNS suffix

ADVANTAGE Node type is Hybrid while dell is Broadcast

dell is Win2k
ADVANTAGE is XP Pro

From the ADVANTAGE I can ping all ip addresses.
From the dell I can ping all EXCEPT the ADVANTAGE (192.168.1.2)

From the ADVANTAGE I can ping nothing by name except ADVANTAGE
From the dell I can ping dell and M1122 by name (I'm not sure of the Name of DI-524)

Both computers can use the internet but cannot see each other.

Can anyone suggest where to look, please?

Checked your firewalls on the PCs?

He he. Just thought of that after I posted.
Disabled PC Tools Firewall on Advantage and was suddenly able to ping dell by name.
Re-enabled it and can still ping by name. (?)

Wait - I'm still investigating this new condition.......

Firewall may be disabling ICMP packets (plus more).

You should be able to set hosts or networks as trusted.

NetBIOS names are cached.

Run "nbtstat -R" , and you'll probably not be able to ping by name anymore.

edit: clarified on netbios as opposed to DNS, after clearing the fluff from my frazzled brain.
