I want to share a folder from a standalone Server 2012 system on a private LAN that other servers can access without authentication. There is no domain/AD in my environment. This is usually a simple process that can be done with just the following 3 steps:
- enable the guest account
- share a folder with both share and system privileges set to allow Anonymous Logon
- add the share name to
Network access: Shares that can be accessed anonymously
My shared folder mounts perfectly fine on other Server 2003 and Server 2012 systems. The following error occurs when I try to mount the shared folder on a Server 2008 R2 SP1 system:
net use * \\192.168.1.1\DeploymentShare$ /user:anyusername
System error 1240 has occurred.
The account is not authorized to log in from this station.
There's a technet explanation for this error:
This issue can occur if the non-Microsoft SMB server supports only unencrypted (plain text) passwords during authentication.
That explains what the problem is, but now how do I fix it?

Windows Server 2008 has
Microsoft network client: Digitally sign communications (always)enabled by default. The error can be resolved by disabling it. Server 2012 does not have it on by default.
