    I am using a stand alone windows server 2008 R2 (no AD), and the computer name is using domain prefix, for security reasons I disabled all inbound and outbound rules within the firewall except for ports 80 and 443. Then I wanted to rename the administrator account I got the error: Unable to access the computer xxx, The error was: The Network Path was not Found.

    Please advice what to do ?

    Hi,

    Why do you use a domain prefix on a stand-alone computer name? That would make the computer be deemed as a domain member server and it would fail to contact such a computer in the unexisted domain when you perform local administrator account renaming.

    Hi Cicely

    It is mandatory in order to use SSL certificate for SQL server connections.

    Hi,

    When you tried to rename local administrator, the server needs to contact SAM server through RPC which is, usually, over SMB and access other network resources. As you have disabled all other rules except 80 and 443 ports, this may be banned by windows firewall and no RPC call can be made successfully. You can try to enable default rules, do whatever changes you want and then disable rules as you did to secure the box.

    Regards,

    Cicely

    Hey Guys but since this server is a stand alone shouldn't it be using the local SAM database?

    The problem is that I do not remember all the firewall default rules I disabled, I am using Remote desktop to connect to my server, and many times I find other foreign addresses connected to it using 3389 port, that's why I think it is urgent to rename the default admin account and to change also the default port number for Remote Desktop.

    if you logon locally to the server and try to change the administrator account do you still get the error. If you want to change the default port for remote desktop you can edit the registry key port number in [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\WinStations\RDP-Tcp] to the port you want to use for Remote desktop.

    Hi Kofiernest

    Please notice that I cannot logon locally, since my server is a VPS type and it is hosted. The hosting company doesn't deliver any copy of it.

    That's why I am affraid about to loose access to it if I am not sure of my actions.

    also I could not find where to change the value in [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\WinStations\RDP-Tcp] since there is too much entries.

    you can create another administrator account if you don't already have one. Logon using the other admin account and then try to rename the  account you are trying to rename.  On a server 2008 R2 machine you can open regedit and then navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber. there you will see the default port for rdp. if you choose to change it before you do remember to open the new port number in your firewall else you will lock yours out. You can take a look at this link http://support.microsoft.com/kb/306759

    Thank you for your efforts to help me, I can also create a new
    adninistrative account then disable the old one. For the port number
    have you an idea on why they let it in Hexadecimal format by default ?

    relating to the port number registry key when you click modify on the key you can change the base from Hex to Decimal and then type in the new port number

    Yes of course, but my question was if you know the reason why they have put two formats ?
