Hi,

I have more than 150 windows 2k prof. pc's managed by two
windows 2000 servers. Everything works fine (Incredible!).

Sometimes one o more desktop computers change DNS
configuration in the network settings so the dns server
address... disappears (blank address: " . . . ."). Amazing.

Users don't have rights to modify this configuration.

Any idea? Thanks in advance,

dns server: windows 2000 server
dns client: windows 2000 prof.

Nothing special,

Are you using DHCP on the Win2k?
Option 006 enabled? With what addresses?

No, I don't: Each client has it Static IP: (192.168.1.x /

You must have a security issue, if DHCP is not in use and the addresses are
statically assigned.
My suggestion would be to set up DHCP. It must be some chore to have to
administer a static network if you have to go to each station to configure
them.

So you're saying that each client is statically configured an IP, Subnet
mask, Gateway, and a DNS address and for some strange reason *just* the DNS
address, but nothing else, just disappears out of the config? Hmm...

Is there any other software or client, such as Novell, or anything else, on
these machines that may affect network configuration somehow?

Is the DHCP client service or NetBIOS helper service disabled on these
machines by chance?

Ok, keep an eye on that stuff. I would also make sure your AV is upto date
and you have some sort of anti-adware and/or trpjan finder too. Check the
Event viewer also.
