Does anyone know how to remove a PPP adapter from Server 2003?  I cannot find anything out there that describes how to even alter or configure it.  I've found plenty of sites describing how to keep its IP from publishing, but that does not help my situation.  Anyone?

Hi theamzngq,

Do you have RRAS installed, most probably the PPP adapter is from an unconfigured RRAS, or VPN Connection. It can also be a modem that is installed in the server.
First of all you have to to find out "who" has installed the PPP Adapter, then remove it accordingly

gjohnson99, where exactly in the device manager would this virutal adapter be?  Its not in the list on my server.

corneliup, I will check out that link.  RRAS is not installed, nor any VPN connection.  We use a hardware VPN.  It could be that at one time we tried to use the server for our VPN, which could be where it came from initially.

I have looked at that link, and I cannot find the virtual PPP adapter listed anywhere in order to remove it.  It mentions a Networking tab, which I cannot find.  Any other ideas?  Perhaps a registry entry or something?  The IP that this virtual adapter is using needs to be removed, as it is causing trouble.

FYI, the 'ipconfig /all' from the server:

Regedit
Registry --> Export Registry File

HKEY_LOCAL_MACHINE --> SYSTEM --> CurentControlSet --> Services --> Tcpip --> Prameters --> Interfaces -->
Make sure that the following interface has the 192.168.234.235 address: 47935FBA-D864-4F89-B0E3-EC0F1E99F0C8
If not, find the one that does.
Delete it.

Look for some software that got installed, like a vpn client software etc, and then uninstall it using Add/Remove software in control panel. You should also find something by using the msconfig utility and checking the programs you have in autostart or services. For testing purposes you can disable those you don't know about and then restarting the server. If something essential doesn't work after that you can allways enable that again.

That is the kind of info I was looking for!  After I deleted the appropriate entry, I ran 'ipconfig' and got the following error:

Windows IP Configuration

An internal error occurred: The system cannot find the file specified.

Please contact Microsoft Product Support Services for further help.

Additional information: Unable to open registry key for tcpip.


Is there something else I need to do?  Restart a service, or the server?

In looking through the registry, there are a ton of entries that refer to that PPP adapter.  Just removing one key couldn't be the entire solution.  There has to be a better way.

It has come to my attention that we might be dealing with a built-in Dell Remote Access Card that is using that address.  It might not be virtual after all...

The registry deletion was to kill the adapter.
What's the issue you're having that you need to remove the adapter?
If it's a hardware piece, you should be able to disable it.

Yes, I believe it is to do with the Dell Remote Access Card.

See: http://support.dell.com/support/edocs/software/svradmin/1.9/en/readme/Readme.txt

The relevant extract from the document:

* A dial-up network connection to the remote access controller is
  established by the RAC managed node software installer. The RAC
  software will not work properly if this dial-up connection is
  deleted or if a proxy is set up in the Internet settings. A utility
  "InstallPPP" is provided with the RAC software to restore the
  RAC PPP connection. This utility can also correct issues with
  Internet connection problems with proxy server settings when using
  the Windows 2003 operating system. The utility can be run from the
  Windows command prompt with the argument "CreateRACConnection" as
  given below:
c:\>installPPP CreateRACConnection

I believe it is a hardware piece, we're still looking into that.  The problem we are having is that when the server tries to sync time to an external time source, such as time.nist.gov, it is trying to use the PPP interface.  Our firewall kills it on the way out because it thinks it is a spoofed address.  I could open it up to allow that, but in the end, this server is our PDC, and in our configuration, it should have only one IP address.  We have no need for this other adapter, and it has caused other issues in the past which we were able to overcome.  I would just rather have it removed.

I'll check with Dell about disabling it or removing it or something if we determine that that is what it really is.

And:
* Due to functional details that are specific to Windows Dynamic DNS
  servers, the RAC internal PPP IP address is broadcast to the Dynamic
  DNS service on servers running Windows. The Dynamic DNS service
  stores that particular IP address in its DNS lookup table and
  associates it with the name of the system that hosts the RAC. This
  action causes problems with Active Directory under Windows. The
  default value for a RAC's internal PPP IP address is
  192.168.234.235, but the address can be changed by the user. This
  issue is a known problem, and there is an article and a hot fix
  available from Microsoft. The Knowledge Base article number is
  Q292822. Downloading the hot fix and implementing the steps in the
  article solve the problem.

Note the IP matches that of your adaptor.

purplepomegranite, that command looks as if it is going to install the connection.  I want to remove it!  I don't need it, and it is causing other issues.

I have taken the steps described in article Q292822.  That keeps the address from being published in DNS, but that does not keep that interface from being used for other connection, for example, time sync.  Who knows what other connection types are being messed up because windows is choosing to use an interface with an IP that is not even in our subnet.

Yes, that command does install the connection, it was just a reference point!  Sorry if it added confusion.

The second extract though shows that the IP can be changed, which would solve your problem in this case.  KB is at: http://support.microsoft.com/default.aspx?scid=kb;en-us;292822

Though the article does refer to a RRAS server, it may be worth enabling RRAS in this case - if configured correctly, RRAS certainly won't make problems for your server.

In fact, if you enable RRAS, you can enforce the machine not to use that interface for routing...

I appreciate all your suggestions.  I think that I need to call Dell about this one and find out if I can disable their remote access card.

it appears as if this was the RAC modem that is built in to the server.  Once that item was disabled in the Device Manager, the IP stopped showing up.
