Yes, my ancient facility is still running our PDC and BDC on Windows NT server. I inheritied this poop-sandwich and am doing my best to digest it. We just got done upgrading our PDC/BDC to Windows 2000 Server. Our Blade Servers are also running, and have been running Windows 2000 Server. So it was just our PDC/BDC that had the NT Server. Anyway, so we now have our PDC/BDC running Windows 2000 Server, and our existing Blade Servers already running Windows 2000 Server. But for some reason we can't get the PDC/BDC to talk to the Blade Server. In fact, when you go to you Network Connections, and try and create a new connection, it gives several options, but doesn't even give you the type of connection you need. There are options for "dial-up" this and that, and whatever else my guys are seing, but nothing that leads them towards a basic network connection. They believe this may be tied to the fact that the internal NIC is not responding, so they're going to download its driver and try and reload the driver and see if that helps. Any ideas? You guys have been AWSOME! I love this site.
