How to configure windows time in windows 2008 r2 domain to announce itself as a reliable time source and uses the built-in complementary metal oxide semiconductor (CMOS) clock

Hello Experts,

I want to configure my windows 2008 R2 Domain  to announce itself as a reliable time source and uses the built-in complementary metal oxide semiconductor (CMOS) clock. And then I want configure my member servers and client Pcs to sync the time to my domain controller. Though I did the as per the Microsoft
 "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags    In the right pane, right-click AnnounceFlags, and then click Modify.
    In Edit DWORD Value, type A in the Value data box.

I still get w32time error on my member servers and clients and also there is time difference between the domain and the clients. Being at middle east I do not have any reliable time source.

Check this link out which shows how to use a manually-edited NTP server list, and make the DC a reliable source.

As far as reliable local time sources for you, take a look at http://www.pool.ntp.org/zone/asia

I do not recommend using CMOS as your reliable source.

Our office is in Kuwait and I could not find any reliable time source for the region. The other link allows to configure an external source. But I want to configure the server to announce itself as the reliable time source and configure the member servers and clients to point to this domain.

I don't recommend the internal CMOS clock either, they are notorious for the amount of drift.  Also, you do not need an NTP server in your region.  Time servers put out 'Universal Time' and your computer adjusts for the local time zone.  You can select any time server anywhere in the world that you have access to and it should work for you.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

As Dave mentioned, it is not a requirement to use an NTP server in your region, however there actually are NTP servers in your region, as listed in the link in my original answer.  Take a few servers from that list and then use the 1st link I provided to set it up.

Iran, Saudi Arabia, Pakistan, Qatar, UAE, etc, all have at least 1 NTP server in that list.

papertrip,

if I use the server for these region, will the server be able to adjust the time difference for  Kuwait? It will be helpful if all the steps can be provided, in order to set the windows 2008 R2 server to be the NTP server using the external source.

Yes it will adjust.  All the instructions are in the first link of my initial answer.

See here: http://support.microsoft.com/kb/816042   There is even a Microsoft "Fix It" for both internal and external references.  It's a pretty long article.

You always need to set the local time zone on your computer.
