Starting Virtualbox guest shows VERR_SSM_LOAD_CONFIG_MISMATCH

The host machine experienced a power failure, when a guest machine was started up it failed with error message below. Failed to open a session for the virtual machine MACHINENAME. ahci#0: The target VM is missing a device on port 0. Please make sure the source and target VMs have compatible storage configurations [ver=6 pass=final] (VERR_SSM_LOAD_CONFIG_MISMATCH). It seems like Virtualbox virtual machine configuration was corrupted. Looking at the virtual machine settings noticed that the virtual HD attached to the SATA port was gone. To workaround this case, re-attached the latest snapshot to the VM. Use Virtual Media Manager to determine the correct UUID.

Mounting Samba share in Windows 7 yields System error 58 has occured

Got a Windows 7 SP1 32-bit Pro machine that have seen various large applications already. So I am not sure if the security policy of the machine is the default. When trying to mount a Samba share got the error message below. System error 58 has occurred. The specified server cannot perform the requested operation. This was done via net use \\<ip>\share . Mounting the share via Windows Explorer yields nothing, just a long wait for nothing. The fix for my case was to change Security Settings | Local Policies | Security Options | Microsoft network client: Digitally sign communications (always) to disabled . You have to reboot the machine for the changes to take effect.
