Win 2000 AD integrated DNS on new DC problem

Windows 2000 mixed mode, all on a single Windows 2000 Domain.
10 zones

Server 1 windows 2000 ad integrated DNS
Server 2 Windows 2000 ad integrated DNS

So a few weeks ago we switched to Windows 2000 native mode, and every thing
appears to be ok.
Let it run for 2 weeks still all fine.

Server 3 windows 2000 DHCP server migrated/moved as per MS kb on to a new
server (virtual)
All still working fine old server dropped off network post migration

Week later
Server4 Windows 2000 (fully patched etc) virtual server
Run DC promo, so we now have 3 AD DC’s DNS installed.

All still looking ok,

Server 2 DC promo dropped to member server (dns runs a caching dns zone) and
then removed off network.

Few days later Server 4 made a Global Cat server.

Now we have a few problems,

When some users logon (Win XP) home drives are not mapping to the correct
directory, Gpolicy is not always running also.
On some PC’s it looks as if its not until post login that DHCP is detected,
time server etc so looks as if the PC cant locate network until much later in
the log on process.

We have also noticed on the new DC that if you click server with in the mmc
DNS snap in that its asking us to Configure a DNS server ! is this not done
as its running as an AD integrated server ?? I can see all the zones
correctly under this server.

Many thanks for your help

I've never ran DHCP on a virtual server and I'm not sure a virtual server is
a good place for DHCPserver to be located.
It's a good idea in your infrastructure to have two Global Catalogs with the
Infrastructure Master FSMO role on a third server that is not a Global
Catalog.

This is done by the DNS Management console the first time you use it, run
through the wizard configure root hints only one time, and the massage will
go away.
 
re root hint, your a star thanks.
all correct now.

is it possable local machines cache or save in registory the old DC/DNS
server and this is why i'm having problems as they query them at logon ?
tcp/ip setting are all correct for the new DC as are scope options on DHCP
Re-join domain may fix it ?

Check DNS to see if the old DC that is no longer around still has its
records in the zone.

What are the clients using for DNS?
