We have a customer with a single Windows 2003 SBS. It is the only existing server in the organisation.
This server is more or less installed the "standard way". The server runs Active Directory, act as file server, Exchange server and a few more thing.

Clients have som strange problems with lost connectivity to the server, like loosing the file shares and similar things for a while, then suddenly it works again. Network connectivity (i.e. "ping servername") is fine, quick and no lost packets at all). I think this problem is due to something with the browser service at the server.

During boot, the following three events are logged:

1. Event-ID 8015. Source: BROWSER
Description: The browser has forced an election on network \Device\NetBT_Tcpip_{7E112CA2-2F32-450F-A7F6-B2B2B4B6C796} because a Windows Server (or domain master) browser is started.

2. EventID: 8027 Source: MRxSmb
Descr: The browser running on the Domain Controller has lost an election.  The computer that won the election is VINGA, on the transport \Device\NetBT_Tcpip_{7E112CA2-2F32-.
 The data contains the election version, election criteria, and remote computer time up, and the same information for the current computer.

3. EventID: 8005  Soruce MRxSmb
Descr: The browser has received a server announcement indicating that the computer VINGA is a master browser, but this computer is not a master browser.

Please point me in the right direction of how to get this right.

Thanks in advance

The "Computer Browser" is a service that starts inside a computer of a domain with an election as your message describes.
In order to solve this problem stop the Computer Browser service in the computers that are not Servers within your domain.

Not the solution you were looking for? Getting a personalized solution is easy.

OK, I missed to tell you that computer named "VINGA" is the server itself. Therefor I think that I need to do something on the server to solve this.
As I said, the problem is not the messages themself, but the fact that the client has big problems with lost connectivity to the shares and similar stuff.

I could disable the browser on the client but I dont think this will do it in my situation.

We had the same issue in our network
The master browser is chosen randomly (by elections)
In my network for some reason my Windows XP machine was becoming the master browser and not one of the 7 different servers that we had.
I don't know the reason but the problem was solved by stopping the Computer Browser on my machine.

I will turn off the browser on the client, but as I wrote above, the message on the server is all about that the server itself (named VINGA) is trying to do things internally but are not allowed.

So basically, what I would like to do is to tell my server that it is "everything", i.ex. master browser, PDC and whatever it could be.
It seem to try to register the browser functionality at itself but fail.

do u have internal network problems??
I mean hubs or switches problems that disconnect and reconnect???
If yes then the di-synchronization may be a result of that.

Do you have dual nics or a VPN connection of some sort where the netbios bind of let's say a VPN connection competes with the other netbios bind of the LAN NIC?

Commented:
The problem is solved. I had dual NIC but only one was enabled.
The problem was probably due to network problems, the NIC had VLAN:s enabled and that caused several network problems. THe VLAN:s are now removed (we made a more simple solution).

Thanks everybody for your suggestions.
