Buenas.
Les quiero comentar algo que me sucedió que me resulta muy extraño.
Tengo un Win2000 con SP1 y una placa de red Realtek 8139 A.
De pronto, el icono que representa a la conexión de red desapareció, pero la
conexión sigue funcionando perfectamente.
Ya bajé los últimos drivers disponibles en el sitio de Realtek y las cosas
siguen funcionando bien, pero el icono no aparece. Yo no lo he borrado ni
nada por el estilo, así que no tengo ni idea de lo que puede ser.
Alguna sugerencia???
Muchas gracias.

Some Network and Dial-Up Connections Icons May Be Missing

The information in this article applies to:

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Datacenter Server
  • Microsoft Windows 2000 Professional
  • Microsoft Windows 2000 Advanced Server

 

SYMPTOMS

After you click Start, point to Settings, and then double-click Network and Dial-up Connections, you may experience one or more of the following symptoms:

  • The network adapter has a resource conflict with another device, causing the Local Area Connection icon not to be displayed. Note that Device Manager may incorrectly show the device to be working properly.
  • The Local Area Connection icon may be missing.
  • The Make New Connection icon may be missing.
  • When you double-click Make New Connection, you may receive the following error message:

Unable to create the specified connection. This can be caused by insufficient memory or not enough disk space.

 

 

CAUSE

This behavior can occur because of one or more of the following reasons:

  • The Plug and Play service is not running, causing the Local Area Connection icon to not be displayed.
  • The Remote Procedure Call (RPC) service is not running, causing the Make New Connection icon to not be displayed.
  • You used the Dcomcnfg.exe tool to change DCOM default settings, causing the error message listed earlier in this article to be displayed.
  • One of the following network dlls is not properly registered.
    • Netcfgx.dll
    • Netman.dll
    • Netshell.dll

 

  • The Network Connections service is disabled or is not started, causing the Local Area Connection icon to not be displayed.

 

RESOLUTION

To resolve this behavior, use the appropriate method:

Verify That the Device Resources Are Correct

To resolve this behavior:

  1. Obtain the network adapter configuration utility from the manufacturer of the network adapter. Typically, you must boot the computer from an MS-DOS or Windows 95/98 Startup disk to run these utilities.
  2. If the network adapter uses jumpers for its settings, verify that the settings do not conflict with another device and manually change them to a resource setting that is not currently in use.

    NOTE: You may need to remove all devices except the NIC and add them back one at a time to determine which device the network adapter conflicts with.

Start the Plug and Play Service

To resolve this behavior:

  1. Click Start, point to Programs, point to Administrative Tools, and then click Computer Management.
  2. Double-click Services and Applications, click Services, and then double-click Plug and Play.
  3. In the Startup type dialog box, click Automatic, click OK, and then restart your computer.

    NOTE: If the Local Area Connection icon is still missing, press F5 several times to refresh the screen. Also, you may try restarting your computer in Safe Mode with Networking.

Start the RPC Service

To resolve this behavior:

  1. Click Start, point to Programs, point to Administrative Tools, and then click Computer Management.
  2. Double-click Services and Applications, click Services, and then double-click Remote Procedure Call (RPC).
  3. In the Startup type dialog box, click Automatic, click OK, and then restart your computer.

    NOTE: If the RPC Service is disabled, you may need to use the Recovery Console. For additional information about starting and using Recovery Console, click the article number below to view the article in the Microsoft Knowledge Base:

Q229716 Description of the Windows 2000 Recovery Console

 

  1. In Recovery Console, run Enable RPCSS Service_Auto_Start, and then restart your computer.

    NOTE: If the Make New Connection icon is still missing, press F5 several times to refresh the screen. Also, you may try restarting your computer in Safe Mode with Networking.

Reset Default DCOM Permissions

To work around this problem:

  1. Click Start, click Run, type dcomcnfg, and then click OK.
  2. On the Default Properties tab, click any setting other than Anonymous in the Default Impersonation Level box. The default setting is Identify.

Register the Following Dlls

  1. Click Start, click Run, and then type cmd.exe on the Open line.
  2. Type the following lines, and then press ENTER after you type each line:
3.              
4.                regsvr32 netshell.dll
5.                regsvr32 netcfgx.dll
   regsvr32 netman.dll
  1. Restart the computer.

 

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

 

MORE INFORMATION
