Vista does not show modem or AirCard when connected to domain

The problem I am running into is that the network connections will not
display my modems even though they are setup. When I try to setup a dial-up
connection, it says that no modems are found. They are setup and functioning
in the device manager. If I disconnect from the domain it sees them. When I
reconnect to the domain it still sees them and allows me to use them. If I
reboot, they disappear.

I also get the error 1297 when trying to start the diagnostic service for
the network and I have gone through the policies to try and figure out the
problem but I am at a loss. When this was an XP machine, it worked fine.
