请求的操作需要在SQL Server中进行提升（以管理员身份运行）

Question

I am trying to execute a xp_cmdshell command to change the ip of the SQL Server server.

The EXEC command is as follows:

EXEC master.dbo.xp_cmdshell 'netsh interface ipv4 set address name="Ethernet" static 192.168.XXX.XXX 255.255.255.0 192.168.XXX.XXX'

The IP is X'ed for security reasons.

The netsh command executes successfully under command console, but the SQL Server query generates the following error:

The requested operation requires elevation (Run as administrator).

The full query code is:

USE MASTER;
GO

CREATE LOGIN [backup-dt\itm] FROM WINDOWS;

EXEC sp_xp_cmdshell_proxy_account 'backup-dt\itm','Letmein@2018'

--Create the database role and assign rights to the role
CREATE ROLE [CmdShell_Executor] AUTHORIZATION [dbo]
GRANT EXEC ON xp_cmdshell TO [CmdShell_Executor]

--Then once done create users and assign to CmdShell_Executor
CREATE USER [Backup-dt\CmdShellExec] FROM LOGIN [Backup-dt\CmdShellExec];
EXEC sp_addrolemember [CmdShell_Executor],[Backup-dt\CmdShellExec];

grant execute on xp_cmdshell to [backup-dt\itm]
EXEC master.dbo.xp_cmdshell 'netsh interface ipv4 set address name="Ethernet" static 192.168.XXX.XXX 255.255.255.0 192.168.XXX.XXX'

Any idea how can I elevate the access to administrator and make this command execute successfully?

Thanks,

this code is going to be a part of another code which checks for another server's availability. If the other server fails for some reason, this server with change its IP to that server's IP to take over the database connectivity

So Windows has a feature for this in Windows Failover Clustering . It will monitor the health of multiple instances, and fail over resources (including IP addresses) to healthy nodes.

You can create a cluster just to manage a floating IP address, and have SQL Server instances running on both nodes. But that's only a partial solution, as the SQL Servers may both actually be online in case of a network issue, and you'll have a split brain.

SQL Server integrates with Windows Failover Clustering to provide two complete, and widely-used HA solutions. Failover Cluster Instances , which use shared (or replicated) storage, and Availability Groups (which don't need shared storage).
