Operating System

Windows Server 2012


File and Storage Services






Srv.sys is not set to start on demand.


Client computers will not be able to access file shares and other Server Message Block (SMB)-based network services on this computer.


NOTE: This BPA message is erroneously produced when the SMB 1.0 feature has been removed from Windows Server 2012.  SMB 1.0 is required for older clients, such as Windows XP.

Set Srv.sys to start on demand.

This can be achieved by running the following command from an elevated command prompt:

sc config srv start=demand

Or through the Powershell way:

Get-CimInstance -ClassName CIM_Service -Filter "Name='srv'" |Invoke-CimMethod -MethodName ChangeStartMode -Arguments @{StartMode='Manual'}
