You see the error message “Err Msg: System Error 1240 Has Occurred. The Account is Not Authorized to Login from This Station”, when attempting to mount an SMB network share.

Applies to:
Iron Networks Products: IronPOD Family of Products, Microsoft CPS
Software: Windows Storage Spaces, Windows 2012 R2
Hardware Components: NA


When connecting to a network share and the share name is incorrect, you will receive a very confusing error message.

net use x: \\ip2-Stor1-SFS\VMImages

System error 1240 has occurred.
The account is not authorized to log in from this station


Selecting the correct share name (VMImages1 instead of VMImages) resolves this.

net use x: \\ip2-Stor1-SFS\VMImages1
The command completed successfully.

This is not a bug, but the error message makes this error quite confusing to decipher.
