I have posted this before, I believe. A Win2k box, either workstation
or server, will by default try to register itself. You can turn off
this self-registration via
To see what options are set:
Start
Settings
Network and Dialup
Local Area
Properties
Adapter
Protocols
TCP/IP
Advanced
DNS
The "Register this name" box should NOT be checked.
If you need to uncheck the box, then you must reboot for the change
to take effect.
Once a self-registration has completed successfully, the Win2k box
will attempt another self-registration at these events (according to a
MS web page [the URL of which I will send in a subsequent posting])
every 24 hours
when the computer is rebooted
when the computer's IP configuration changes
when any plug-and-play event occurs
On our Win2k testbed, I was seeing self-registrations at these intervals
a few days after the one self-registration completed successfully:
5 minutes
10 minutes
60 minutes
5 minutes ...
I assume that the MS code expects the MS DNS "scavenger" code to be
running; that code might unregister the computer if it is off of the
network. In my testing, I allowed only ONE sef-registration to succeed;
I wanted to get a trace of the DNS update packets.
