I'll try to be as descriptive as possible. Certain computers that I have simply cannot be seen on the network. I've got 8 computers on a 48 port 10/100/1000 switch that's plugged into a 2Wire Gateway. All are running XP Pro. 3 of the computers cannot be seen on the network, although they can see the "working" computers and browse the internet. Here are the things you might ask me to do that I've done. 1. I've tried with and without NetBEUI installed 2. I've completely turned off Windows Firewall and do not have any other firewalls installed. 3. These 3 pcs all have a fresh xp install. 4. They are all on the same workgroup 5. A folder on each is shared 6. I've tried with Simple File Sharing on and off 7. I can ping all the computers by both ip and name 8. The computer browsing service is started 9. I've even resorted to using the networking disk to make SURE all the settings were the same on all computers. I'm baffled. Any ideas, PLEASE?
