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.
