Console msg; "address has changed from".

By Dan M. ·
My Netware 4.10 server console is constantly scrolling the following message:
"1-8-01 11:46:22 am: SERVER-4.10-3191
Server (Win 9x workstation name) address has changed from AF711E8F:00E029481B52:0555 to AF711E8F:0000B49D80BC:0555
Informationcame from router at 0000B49D80BC"

This message is filling my error log and is interfering with the ability to do anything at the console. Other than that, there are no performance problems.

I currently have about 50 Windows NT/98SE and 95 workstations connected to this server via a few 3COM Superstack 10/100 switches. The workstation name and addresses in the message flips back and forth between about 4 of the workstations (Win 98SE and 95 only). The server is configured for IPX only.The workstations have both IPX and TCP/IP and they are not setup for file and print sharing (which is what I though the problem was at first).

Please advise.

You can try reseting the server router by entering "reset routers" (w/o quotes) at your server console. I usually see this if there was a change to the network number assigned to the network card when it binds IPX to the card. Has any changes beenmade to your network such as new routers, hubs, switches, etc? Also, are there multiple network cards in your server? Switching the patch cables from one card to another will also cause this error message.

I forgot to mention in my original post that I did try "reset router" (many times) and it didn't help.

There is only one NIC in the server, and there are no new switches or hubs. I did purchase a "spare" Ascend Pipeline 50 router and we plugged it in to configure it. We then took it off and we are NOT currently using it.

I can't pinpoint any specific changes but I think it MIGHT have been around the time I deployed a few new Dell Optiplex's with Win 98SE. (The messages are not on just those machines though. Some of them are older HP Vectra's with Win 95). At first when I investagated this problem, I found an article on how file and print sharing could cause this. The new Dell had file and print sharing enabled so I disabled it and the messages went away. A short time later, they came back (different machines). I'm not sure what had changed though.

When it states that the "information came from router", which router? An internal router or our Ascend Pipeline?

The problem is quite simple. Two of your workstations have the same Computer name. This happens quite often if you are using an ghost image to set up your workstations. The techs don't always remember to change the workstation name.

Check yourlog to see when this started and see if that corresponds to any new workstations being setup.

I am using TrackIt! to audit my workstations. It captures the workstation number(unique key in TrackIt!) and the MAC address of the adapter so it is easy to print a report by MAC address and see which two workstations are conflicting.

As bdgray said, the stations have the same names (which should be corrected)... but they also have the option "I want to enable NetBIOS over IPX/SPX" enabled, otherwise the NetWare server wouldn't "see" them at all (unless they had File and Print Sharing for Novell Networks enabled)... and, the stations don't have the Client for Microsoft Networks loaded, probably, because if they had you'd get a name conflict error from Windows on the PCs themselves (I think? I don't do MS peer to peer stuff very much, but it is based on NetBIOS, so that would make sense).
HTH,

Apart from the other replies, what can be done faster: reinstall the latest Novell client on the pc with that mac-address, and if that doesn't help, change the network adapter in that pc (not necessarily another type).
Let me know if this helps.

Concerning the last reply. This is not a client install issue or adapter issue. It's simple two workstations on the network with the same name. Once you find the offending workstation and change it's netbios name, the error will go away.

Same machine name (the ones that are instaled without being connected to the network) and the plugged to the network.

You need to identify who?s PC hold one of the networks card in order to fix the problem.
The matter is HOW!
Ip?s Wks through DCHP? Good!
Go to DCHP admin, active leases, one by one (50 is not a number! I have more than 1800!)
select view properties, watch for unique identifier (that?s NIC address). When you find one of the two Nic?s then you have the name of who?s login in.
With this name go to User manager for domains and retrieve it's full name, with this, go to your telephone list, place a call at lunch time, first retrieve the place where is him and then. Ask Him to close all files , unplug the network card andgo to have lunch.
IF (only IF) after a couple of minutes screen messages disappears!
Go there and fix it before he came back
((remember to replug the network!!!)

Hope it works!

Could you help me understand what "fix it" is.

Because I have <50 users, I can easliy identify which workstations are causing the problem. I've tried renaming the computer (the problem comes back with the new name), I've tried reloading the client (again, the problem comes back) and I can't replace the NIC because it's built in. I've also disabled NetBIOS in the offending PC's.

The only thing that stops this message is shutting the computer(s) off.

Is there a table that it is referring to that needs to be reset? If so, might anyone know where it is and how I can reset it? As I mentioned in my earlier post, I've tried the "reset router" command on the console with no avail.

Any other comments or suggestions are welcome.
