I've got a single SBS 2000 server that is no longer displaying the items under Network and Dialup Connections. The 2 Ethernet interfaces are still up and passing traffic.
I tried following the steps in MS Knowledge Base Article 329050 - Troubleshooting MissingNetwork and Dial-Up Connection Icons, but haven't had any success so far.
In the article step 2 states that the Network Connections service should be running. It does not start. I have confirmed that the RPC service on which it depends is started. There is nothing I could find on what to do if the Network Connections service will not start.
