Replaced NIC and now networking is broken

I'm running VMWare Server on a Suse 10.1 linux workstation.  My motherboard was replaced yesterday and there is a new NIC with a new MAC address.  Now my VMware guest OSs won't connect to the network.  I get the following error:

"The network bridge on device /dev/vmnet0 is temporarily down because the bridged Ethernet interface is down.  The virtual machine may not be able to communicate with the host or with other machines on your network."

I tried reinstalling VMWare Server and told the install to remove the old vmnet configuration and make a new one...which it did.  But I still get that error.

Anyone know how to fix this problem?

Thanks,

Matt
