Create a demand dial interface with netsh in Windows 2008 fails

Hello all,

I want to create a dialup connection using netsh in Windows Server 2008. The
dialup device should be a modem or an ISDN device. Both devices are connected
to server, the drivers are installed.

Using the wizzard in Routing and RAS I am able to set up a new dialup
interface for a modem or ISDN device successfully.

The goal is to set up the dial on demand interface using netsh. According
the the documentation
http://technet.microsoft.com/en-us/l.../cc732846.aspx I used the following
command:

netsh routing demanddial add interface name=mycon type=dialup
host="89675342" device="AVM NDIS WAN CAPI-Trieber (1) (ISDN12-1)"
user=Administrator password=password

The command creates a dialup interface but the used device (eg. AVM NDIS...)
is not that I used in the netsh command. It seems that always a default
device is used.

I tried to use the device names shown in the wizzard and the device names
shown in the configuration dialog box of the dialup interface but always the
"default" device is used.

Can anybody give me a hint what to do? Where can I find the correct device
names to use with netsh? Is there a known bug in netsh?

Thanks for help
