You are the systems administrator for your company. The network contains a Windows Small Business Server (SBS) 2003 computer named SBS_Srv. To migrate to Windows Essential Business Server (EBS) 2008, you install Windows EBS 2008 on a computer named EBS_Srv. You migrate the required accounts and settings from SBS_Srv to EBS_Srv. After a week, you discover that SBS_Srv is restarting every hour.

What should you do to ensure that this problem does not occur in future?

A.
Install a software update on SBS_Srv to support a join-domain migration of Windows SBS 2003 data and settings.

B.
Remove SBS_Srv from the network.

C.
Disable the DHCP Server service on SBS_Srv.

D.
Uninstall Active Directory Domain Services (AD DS) from SBS_Srv.

Explanation:
You should remove SBS_Srv from the network. When you install Windows EBS 2008 during the migration from Windows SBS 2003, the Windows EBS Installation Wizard transfers the Active Directory operations master roles from Windows SBS 2003 to Windows EBS 2008. If you continue using Windows SBS 2003 without the operations master roles, the Windows SBS 2003 server will restart every hour, beginning from seven days after the transfer. To prevent this, you should either remove the server running Windows SBS 2003 from the network or shut down the server.

You should not install a software update on SBS_Srv to support a join-domain migration of Windows SBS 2003 data and settings. Installing this software update extends the grace period for which you can use the Windows SBS 2003 server from seven days to 21 days. After 21 days, the server will restart every hour as described in the scenario.

You should not disable the DHCP Server service on SBS_Srv or uninstall AD DS from SBS_Srv because this will not prevent SBS_Srv from restarting every hour.
