Network has gone nuts!
Hey all, I am not real sure this is the right forum to list this in so if any of the Mods want to move it thats ok by me.
I have a simple home network with 2 computers each running win2k pro, SP4, patched up to date. For months I have used one computer to connect via dialup to the internet using internet connection sharing I connect the other machine to the internet through the first box. We have never had any problems until this afternoon when I tried to connect a friends win98 box into my network to access the internet. Suddenly my network is broken and no amount of restarts or reconfiguration manual or automatic will get the two to talk with each other again. when I look at the event logs on the first box I see:
The master browser has received a server announcement from the computer MELTDOWN that believes that it is the master browser for the domain on transport NetBT_Tcpip_{8F6F7A7F-A376-4C0A-. The master browser is stopping or an election is being forced.
Meltdown being the name of box 2
This may sound stupid, and I feel I should know how to make these boxes work together, never have I had this kind of problem, I have also tried to manually configure IP addresses for these two using the common 192.168.0.1 and 192.168.0.5 with a subnet mask of 255.255.255.0 for both, placing them both in a workgrop called HOME or whatever. Still they will not transfer packets between one another.
Someone please tell me what I am doing wrong before I go completely mad.
I have a question; are you the bug, or the windshield?

Nice try but no cigar... the link you provided has to do with computers on a domain, and if I try to find out more about it they want to sell me a subscription. These are simply two computers on a home network that used to work fine and now will not. I have even gone so far as to reinstall windows on box 2. Same friggin errors....
I have a question; are you the bug, or the windshield?

I assume thatyou have removed the third unit ?
When you added the third unit, what exactly did you do ?
When you removed it, did you reverse the above ?
What exactly, was your friends PC being used for ?
As the error message suggests that it had been set up as a DC ? and it doesn't like sharing
Have you tried to set your box back to IP automatically, reboot, set the IP manually, reboot [again] and see if it starts to behave ?
Luck to you
I'm having a little [lots of] difficulty getting my network off the ground, again two PC's XP Pro on one, W2K Server on other.
so now I'm in my SIXTIES FFS
WTAF, how did that happen, so no more alterations to the sig, it will remain as is now

I removed the 98 machine instantly after my connection on box 2 was interrupted. I have been doing some googling of the problem and have come to the conclusion that the 98 box wanted to be the master browser in turn causing the conflicts with the other two machines. I have set both win2k boxes back to the static IP addresses they originally had. I even reinstalled windows on box 2 and got the same errors. One update though is that I did a search for box 2 from box one and it was found, although there have been zero packet transfers between the two. If I do a search from box 2 to try and find box 1 I get nothing.

Hi
In an initial step, I am trying to gather infos for this problem. To fix the idea,
I am thinking in the lines of a name resolution problem.
- are you using NetBIOS via TCP/IP? ie is/was the traffic on 137-139 or 445?
- on box 1: are the computer browser-, workstation- and server-services running?
- on box 2: does ping box_1_name work? if not, does ping 192.168.0.1 work?
(I assume 192.168.0.1 is the IP of box 1). -> WINS resolution problem.
- One useful tool for troubleshooting NetBIOS problems is nbtstat[1], which is
part of the resource kit[1]. What does
Code:
> nbtstat -n
> nbtstat -r
tell you (shows resolved names)?
Code:
> nbtstat -A 192.168.0.1
> nbtstat -a box_1_name
result?
As per the master browser issue. In theory ( ) there are announcements all 12-15 minutes[2,3].
Even if the Win98 caused a problem here, this issue should resolve itself automatically.
If a master browser is not found, an election is forced[4]. Next step: browstat/browcon[5].
In addition, try a "search for computers" but enter the IP rather than the name of box 1.
Cheers.

As for renewing itself its been over 4 hours without my changing anything and still is not working, funny thing is that box one shows both computers in My Network Places, but when I click on the icon for box 2 it just says //Meltdown not accesable network path not found. How did it get the name of box 2 without a network path? Box 2 only shows itself. no packets recieved on either box, many have been sent.
Browstat.exe only applies to win2k adv server and server, I don't have these on a domain.
I have a question; are you the bug, or the windshield?

Hi
I am puzzled by the outputs of nbtstat. Sorry for inquiring, but is the shown
result for nbtstat -n and nbtstat -A 192.168.0.1 really as is? What are
the results from box 2 (in particular the -a and -A options).
Just to make sure: NetBIOS over TCP/IP is activated and 137-139 (UDP and TCP, both
for simplicity) is allowed (on the local subnet)?
Let's try to enforce a new browser list and master (browstat does also work for win2k
workstation). For simplicity: shutdown box 2, restart box 1. (afterwards, do the same
switching box 2 <-> box 1) (maybe an overkill here ...) then, on box 1:
Code:
> nbtstat -RR
> nbtstat -R
> browstat status HOME
> browstat elect [transport] HOME
> browstat status HOME
the first browstat status HOME provides you with the transport address.
Restart the second machine, do the same. check with browstat status HOME
which machine is the master. I just have set up the same setup here, and this
procedure cleared the list, everything is running smoothly.
It's been a while I had to struggle with this (I am working with net use,
and never view the network neighbourhood), so I am shooting a bit in the dark.
More experienced people might know more efficient ways, better tools, ...
Good luck.
Cheers.

If I disable the nic in box 2 I get this after disable/enable the nic on box 1:
Code:
Local Area Connection:
Node IpAddress: [192.168.0.1] Scope Id: []
NetBIOS Local Name Table
Name Type Status
---------------------------------------------
INNOCENT <00> UNIQUE Registered
INNOCENT <20> UNIQUE Registered
WORKGROUP <00> GROUP Registered
WORKGROUP <1E> GROUP Registered
WORKGROUP <1D> UNIQUE Registered
..__MSBROWSE__.<01> GROUP Registered
\Device\NetBT_Tcpip_{337580CB-3D98-4ECE-8FBE-67865980D55C}:
Node IpAddress: [64.91.19.55] Scope Id: []
No names in cache
Then when I re enable the nic in box 2, in about 15 minutes I get an event message:
The master browser has received a server announcement from the computer MELTDOWN that believes that it is the master browser for the domain on transport NetBT_Tcpip_{8F6F7A7F-A376-4C0A-. The master browser is stopping or an election is being forced.
Then box one gets this from nbtstat -n:
Code:
Local Area Connection:
Node IpAddress: [192.168.0.1] Scope Id: []
NetBIOS Remote Machine Name Table
Name Type Status
---------------------------------------------
INNOCENT <00> UNIQUE Registered
INNOCENT <20> UNIQUE Registered
WORKGROUP <00> GROUP Registered
WORKGROUP <1E> GROUP Registered
MAC Address = 00-50-BA-4A-0F-F8
\Device\NetBT_Tcpip_{337580CB-3D98-4ECE-8FBE-67865980D55C}:
Node IpAddress: [64.91.19.55] Scope Id: []
Host not found.
Then I look at box 2 again and it now is the master browser! How do I keep this from happening? Box 1 has to be the master browser, but it always loses the election. I don't have a modem for box 2, and I can't remove the modem in box one as it is an ISA modem and box 2 is PCI only. and even when box one wins and box 2 concedes I still cannot send packets either way. I am about to throw both of these out the window. I'm sorry but the Browstat package requires the .net framework and I don't have it installed on either box. Too large to download over a dialup conn.
I have a question; are you the bug, or the windshield?

Hi
You can omit one box from being part of the election using a
registry key change[1].
Code:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters
-> IsDomainMaster = Yes (on box one)
-> MaintainServerList = No (on box two)
I'm sorry but the Browstat package requires the .net framework and I don't have it installed on either box
That's a pity. I did not know that.
A (last) question:
Can you perform on box two an
Code:
> net use z: \\192.168.0.1\c$ /user:administrator
respectively 192.168.0.5 on box one?
I still cannot send packets either way
Could you be more specific? You can ping I assume. Maybe the above net use
works. Are you refering to th internet connection sharing (box 2 via box 1 to internet)?
Cheers.
