Hi,

How do I setup my DHCP to add DNS Suffix'es to my "Append these DNS Suffix" in my dns settings of TCP/IP
or is there anything in AD to force those entries.

Manually TCP/IP setting works fine, but using DHCP does not seem to have that option?!?

Help is appretiated
Thanks

What kind of DHCP server are you running?

If you are running DHCP from a home router, you can try adding the "domain name" to the router.  If you cannot do that on your router, then you don't have much of a choice.

If you are using Windows' DHCP, then go to your DHCP mmc, go to "scope Options", and add "DNS Domain Name" (typically option 15) and type in your suffix.

I ran a reg search on a bogus domain that I added on a W2K3 machine and found the domain in the following locations:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\SearchList  suffix1,suffix2,suffix3
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\SearchList  suffix1,suffix2,suffix3

You could try importing the values into each workstation via a script.  This is how I am doing it.  I could not find options within the DHCP scope that would add the extra suffix.

Yes did that as a temporary solution 2 weeks ago, but this required a vistit to all PC's (1.300 or so) - so this was quite a bit of work!

- still search for a automated solution.

thanks anyway swincp.

LotharGores- Just follow and read the instructions very carefully.... copy the TCPIP.adm excatly how is writting in the link i gave you...from "CLASS MACHINE" to "SUFFIXSEARCH=DNS SUFFIX SEARCH (SEPARATE MULTIPLE ENTRIES WITH A","): and the do this save it as tcpip.adm either into your %systemroot%\inf folder or wherever you want to save it, then add it to your administrative templates in the Group Policy MMC. (Import the TCPIP.adm template to your computer settings..Do you know how do this???) Make sure to uncheck "Show Group Policies only" in the "View" menu (when "Administrative Templates" is highlighted), as this is not a "Group Policy" but a "Preferred Setting"; it will not revert back to the original setting if you remove the "policy". Don't set this policy to "disabled". Test it before you apply it in earnest.
As this means editing the registry, the usual disclaimer:
WARNING: Editing the registry incorrectly can cause serious, system-wide problems that may require you to reinstall Windows to correct them. It cannot be guaranteed that any problems resulting from the use of this policy file can be solved. Use this tool at your own risk ...

are you able to see your imported setting yet??
