I installed Hyper-V on a production server 2008 r2. After realizing I didn't want to use it I removed the Virtual server, which was never started, and uninstalled the hyper-v role.<br />
Now the server name has been changed to the name given to the hyper-v server. <br />
<br />
When I open server manager it gives me an error &quot;Device manager is running in read only mode because you are running it on a remote computer&quot;<br />
In server manager at the top it says my server name is &quot;WIN-IPE632OG13D&quot; instead of &quot;SQL1&quot; like it should be.<br />
<br />
This is causing some SQL1 service to not run. The main SQL database has not been affected and it is still in production.<br />
<br />
I need to get this back to SQL1. Any help is appreciated.

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
