Issue



When you try to push an installation of Symantec AntiVirus Corporate Edition 8 or Norton AntiVirus Corporate Edition 7 as a managed client , you see the error message "Network Name not found," or a message indicating that the server name is not found.


Solution



This can happen if the VPHOME share on the server does not exist. By default, the server creates the VPHOME share at the time of installation. If the share is missing, then you must create it manually.

To create the VPHOME share
  1. In Windows Explorer, navigate to the installation folder of your Symantec antivirus product. By default, this is either C:\Program Files\Nav or C:\Program Files\Sav.
  2. Right-click the Nav or Sav folder, click Properties > Sharing.
  3. Select Share this folder.
  4. Type VPHOME for the Share name.
  5. Click Permissions.
  6. Ensure that Everyone has Read access. Click OK.
  7. Click Security.
  8. Ensure that Everyone has Read access, and that System and Administrators have Full Control.

Once you have verified that the VPHOME share exists on the antivirus server, continue with the solutions below on the client computer:
  • If the default shares C$ or Admin$ are missing from the client computer, this error message is generated because the installer cannot attach to the drive specified in the installation path. The default shares are normally created during the Windows NT/2000/XP installation.
  • This error can also be caused by an enabled Windows XP Internet Connection Firewall.

Continue reading this document to identify and resolve the issue in your environment.

Missing or unavailable shares

Missing C$ or Admin$ shares
If you cannot locate the C$ or Admin$ shares, you can create them at the command prompt.

To create the default shares at the command prompt
  1. Click Start > Run.
  2. Type cmd and then press Enter.
  3. Type net share C$=C:\ and then press Enter to create the C$ share. A message should indicate share C$ was shared successfully.
  4. Type net share Admin$ and then press Enter to create the Admin$ share. A message should indicate share Admin$ was shared successfully.
  5. Create any other shares needed.
  6. Type exit and then press Enter to close the command window.


Note: The C$ path must be to the root of the drive where the operating system is installed. Make sure that the NetBIOS protocol is installed.
    Citrix metaframe servers
    These servers remap the drives so that what would have been drive C is now a different drive letter. For example, if your remapped drive was drive M, then you would need to type Net Share M$=M:\ to make this change. Additionally, many Citrix server installations configure the AutoShareServer registry entry to disable the viewing of administrative shares. Please see the following section for further details.

    AutoShareServer is disabled
    This situation is often caused by the presence of the "AutoShareServer" registry entry, which prevents the default admin shares from being visible on servers. This value can be found under the following registry key:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

    If you find that the AutoShareServer key is set to "0", there are two options available for resolving this error:
    1. To temporarily enable the administrative shares to allow the install, follow the above instructions to manually add the shares, then proceed with the installation. The shares will be active during the install process, but will disappear again upon reboot.
    2. To permanently re-enable the admin shares, use the Registry editor to change the AutoShareServer value to "1."


      CAUTION: Symantec strongly recommends that you back up the registry before making any changes. Incorrect changes to the registry could result in permanent data loss or damaged files. Please make sure that you modify only the keys specified. Please see the document How to back up the Windows registry and How to use the Windows Registry editor before proceeding.

    To edit the registry
    1. Click Start > Run. The Run dialog box appears.
    2. Type regedit.exe in the Run box, and then click OK. The Registry Editor opens.
    3. Navigate to the following subkey:

      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
    4. Double-click the "AutoShareServer" value in the right-hand pane, and edit the value to be "1" (decimal).
    5. Click Registry, and click Exit to save the changes and close the Registry Editor.

    Windows XP Internet Connection Firewall
    This situation may happen when the Windows XP Internet Connection Firewall is enabled. Temporarily disabling the firewall will resolve the error and allow Norton AntiVirus to install successfully. For information, see the Microsoft article number Q283673, HOW TO: Enable or Disable Internet Connection Firewall in Windows XP.
