Re: Different views of the same network...

Hello sarkiaponius,

Using my network to see all machines requires at least that you enable NetBIOS over TCP/IP (network properties>TCP/IP>advanced>WINS>enable netbios over TCP) on all machines and if you have multiple subnets you have to use a WINS server in the network.

Hi,

first of all I beg your pardon for my english. Also, be kind to me,
because I'm a Windows guy: though I went to some Microsoft courses and
I even take an official exam with success, in the end I'm a Linux guy.

My problem concern browsing the network. We only have a single domain,
with two domain controllers both running MS Windows Server 2003.
Normally, all pc's and servers, when they browse the network with the
usual "My Network" tool, see exactly the same network. I mean they all
see the same hosts listed in the "My Network" window. Also, they all
see the same workgroups (actually, there are very few hosts not inside
the domain, but that's what we want).

Recently, I could say a week ago, someone told me he could not see the
host of a colleague. I took a look at the list of hosts he had in "My
Network", and I realized that the list was different from the one I
was able to see on a server I was working on at that moment.

After a while, I also realized that the two list were disjoint, and
the union of the two lists was equal to the actual content of the
network. In other words, the network seemed to be split in two parts.

But this is only true for browsing: using "search" in "My Network"
allowed us to find the "missing" host, and any other host not listed.
Also, shared folders are still accessible with the right permissions.

Finally, I made a network hardware test. We have 5 switch, and I
noticed that some of the hosts my colleagues can see browsing the
network are all connected to the same switch. So I tried to disconnect
one of this host from that switch and to connect it to another one,
and after the obvious "refresh" of the network window... the host was
able to see the other half of the network!

My idea is that one of the switch, or maybe the network device to
which all the 5 switch are connected (sorry, I don't know the name in
english, but it's a Network Xtreme Summit 5i), has some problems. But
since all these devices are managed by an external firm, I must be
sure it's not my fault. I only administer the domain and some other
services, not the hardware devices.

A couple of years ago, we noticed something similar, and after a month
the Summit 5i got broken and it was substituted wih a new one, and
every problem disappeared. That's why I suspect it's its fault this
time too.

Best regards.
