Unable to access File/SMB Shares | Server 2008R2

    Question

  • Running Windows Server 2008 R2 (DC) and am unable to access any other servers SMB/File shares. Clients can access the shares on this server without any issues.

    When you access \\servername is simply displays and error:

    "Windows Cannot Access \\servername" 0x80070043 The network cannot be found.

    This happens when trying to access all servers in the domain, even \\localhost errors.

    • Server has been rebooted.
    • Windows Firewall is disabled/switched off
    • All DNS is working correctly, name resolves correct IP.
    • Unable to access server via IP
    • Network Discovery is turned off
    • Server is unable to access any other servers or clients, Windows7, Server 2003, Server 2008R2
    • Can RDP to and from the server
    • Server is fully connected to the network.
    • "Server" services has been restarted.

    I'm not sure if this maybe this maybe related to "Network security: LAN Manager authentication level" as I've seen issues with this before. Currently set to: Send LM & NTLM - use NTLMv2 session security if negotiated

    Thanks
