changes. I have a Windows 2000 Domain Controller, a
Windows 2000 client and a Windows XP client. What are
the registry changess that I need to make to each machine?

I am assuming that I need to add the
AllowSingleLabelDnsDomain value and the
UpdateTopLevelDomainZones value as they do not come up on
a search of the registry. Could you specify exactly
which location to add them to for each type of operating
system?

Also, do I set the REG_DWORD value to 1?

Thanks!

You have to use regedt32 to add the value (edit new value) don't be afraid
to do this just BE CAREFULL

Domain Members *not* on DCs
To enable such a domain member to use DNS to locate domain controllers in
domains with single label DNS names in other forests, set the
AllowSingleLabelDnsDomain (REG_DWORD) registry value to 0x1 under the
following registry key on each domain member:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters

XP and Win2k clients and DCs

By default, Windows XP and Windows 2000 SP4-based DNS clients do not attempt
dynamic updates of any single-label DNS zone (.com, .net, .org, corp, and so
on). To enable such clients to attempt dynamic updates of a single-label DNS
zones, set the UpdateTopLevelDomainZones (REG_DWORD) registry value to 0x1
under the following registry key on clients that attempt to dynamically
update the single-label DNS zone:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DnsCache\Parameters

Win2k

The UpdateTopLevelDomainZones registry value was originally located in the
following location of the registry, but was moved before the release of
Windows XP:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
 
On all machines in the domain including DCs and clients add the following:
AllowSingleLabelDnsDomain
(REG_DWORD) registry value to 0x1 under the following registry key on each domain member:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters

UpdateTopLevelDomainZones
(REG_DWORD) registry value to "0x1" (without the quotation marks)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DnsCache\Parameters

Note For Windows Server 2003, the
UpdateTopLevelDomainZones
value has moved to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\DNSClient
