Wow, shades of the past...

Aren't you running SP4? Then what your boss did is fine.

A reboot will be enough. (Actually you can stop netlogon, remove netlogon.dns, 
restart netlogon, then do an ipconfig /registerdns, if you don't want to reboot 
- a reboot might be easier.)

Subject: "Island" DNS server problem for a forst/

I have a Win2000 AD, in a parent-child configuration. I have the "island" DNS 
server problem

The so-called "island" problem occurs when a domain controller that is the 
primary DNS server for the domain, points to itself as the preferred or 
alternate DNS server for the zone _msdcs.<DNS
Forest-name>.
<http://technet.microsoft.com/en-us/library/cc749944.aspx


That's my problem - the primary DNS for my parent domain (i.e.,
forest) points to itself as primary DNS server (secondary DNS server points to 
another DNS server in that domain). We want to demote this server back to a 
member server, but continue to have it act as primary DNS server for the forest 
(temporarily). We plan on upgrading the domain to Win2003 this weekend, and 
we'd like to have the current primary DNS server remain as the primary DNS 
server for the forest - that will save us from having to change the static DNS 
settings on all my servers.

So, my boss changed the order of the DNS servers setting in the properties of 
TCP/IP on that server; the primary DNS setting for that DC now points to 
another DC in that domain, and the secondary DNS server is itself.

DC1 - primary DNS set to DC2; secondary DNS set to DC1
DC2 - primary DNS set to DC1; secondary DNS set to DC2

I think that's how the DNS should be set. The question is: do I need to 
"ipconfig /registerdns" on DC1 after changing the settings to the above? Or 
will a reboot be enough?

The server passes the "dnslint" test properly, BTW - I'm just afraid what will 
happen if we demote DC1. I think the DNS server will stop working, or lose it's 
configuration totally. That would be BAD ....

Thanks
