Linux – Unable to open a Linux SMB share from the domain controller

linuxserver-message-blockwindowswindows-server-2003

I am trying to access the SMB share which resides on one of my linux development servers, whether I type \\servername or \\192.168.0.100 (it's ip), I get asked for the username/password and then it gives the error:

"\\servername not accessible. You might not have premission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

The specified network name is no longer available"

I am able to access this from my workstation or another Windows Server 2003, but not from either of our domain controllers (also Windows Server 2003)

Check your local security policy (secpol.msc) isn't trying to force you to use NTLMv2;

Change these settings;

- Microsoft network client: Digitally sign communications (always) : Disabled

- Network security: LAN Manager authentication level : Send NTLM response Only

  • Network security: Minimum session security for NTLM SSP based (including secure RPC) clients : No Minimum

  • Network security: Minimum session security for NTLM SSP based (including secure RPC) servers : No Minimum

Cheers,
