For the record, it turned out to be missing records in DNS. &nbsp;All of the Resource Records were missing. &nbsp;Once I forced the SBS server to register itself in DNS they were recreated and all was right in the domain.<br />

We're adding a new Win 2012 R2 member server to an existing SBS 2003 domain. It successfully joins the domain, but on successive reboots fails to id the network as a domain network and so it defaults to a &quot;Public&quot; network and fails to authenticate to the DC. On each reboot, in the Event Viewer, the NIC shows that it is &quot;disconnected&quot; and then 6 seconds later Netlogon reports that it can't find a DC. &nbsp;We've experimented with adding &quot;Netman&quot; as a service that Netlogon depends on, but have not had any luck. The NIC has the newest available driver. &nbsp;<br />
<br />
Any advice?

Windows 2012 R2 Server Joins SBS 2003 Domain But then Fails to Find It on Reboot

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
