RAS connection via MS VPN - change MAC Address

[Guest akf-admin]

Dear All,

I have a little problem.

 

We decided to use the MS VPN Client to connect our employees to our network,

because it's "build in" and the computer will be full managed logged to the

network while using a RAS connection.

 

Our Structure is a 3rd Party Firewall Appliance, MS RAS, RADIUS and

Certificate Server. Also we use MS SMS 2003 to deploy software updates.

 

Problem:

The MS VPN Client cames always with the same MAC Address,

to connect to the RAS-Server.

In this case it is impossible to set an ip-address reservation within the

DHCP server.

So the VPN Client changes it's IP with each new connection.

 

Our SMS 2003 Server will recognize each new IP Address of our VPN Clients

and will scramble it within his collections.

You will see each client with more than one IP-Address and with more than

one name.

On custom collections the client will be false selected in case of multiple

IP's.

 

 

In this case I like to know, how to customize the MAC Address for the MS

VPN-Client.

 

 

Things we tryed untill yet:

- searching within the knowledgebase / internet, with no response.

- hacking the MAC-Address within the registry like a normal network card, no

response

- using the MS Server-Connections tool from 2003 Server, but no way to

choose a

MAC other than standard.

 

 

Thank's for any answer or hints to solve our little problem

 

With kind regards
