"Duplicate name on network" error using Netbeui

Hi, all:

Have three computers networked through a router using Netbeui.  Two are running Win98, and the third is using XP.

Since adding the Netbeui protocol to the XP machine, I keep receiving the following message at bootup:  "Duplicate name exists on network."

I tried renaming the XP machine to XPDesktop, but I am still getting the error.  I tried deleting Netbeui, which cures the error, and reinstalling it, which brings it back immediately.

Any possible solutions to this wacky problem?

Thanks in advance!!

Hi DeannaRV,

Are you using Cable/DSL router?  What is the brand of your Router? The router is also your DHCP server right or you are just using static IP.  What is your win98 machine's name?  If it is static can you please provide IP address of each...it will be easier if you run ipconfig /all in command prompt on all three machine.

Do you perchance have two NIC's on the same PC?

What other protocols are you running, or are you only using NetBEUI?

If you are also running TCP/IP, turn off NetBEUI, and add the computer names and addresses of all devices to the LMHOSTS file of all of the PCs.  Make sure WINS is off and LMHOSTS is on.

Thanks to all who commented!

Late last night, I read the Microsoft links submitted by Wiired, and figured out that I needed to removed Netbeui from one network adapter in my network bridge.  Up till that point I hadn't even realized that I had two of them!  I guess one connects to the Internet and one connects my home network??  Not sure ... but at any rate, the problem is fixed and everything seems to be working well.

Thanks again for your help!
