Ok, I just recently installd and attempted to configure Windows 2000 Server. Although I am something of a n00b when it comes to servers, I was able to get the DNS working ok. The problem is with the DHCP (and also netlogon).
Once I was able to get it to release an IP address (and I am still not sure how I did that), and so I tried to login on a workstation with the network account I created (and yes, the computer is in the Active Directory). However, it wouldn't work and in the event viewer I got an error message saying that the computer "failed to authenticate. access is denied". I'm not really sure what the deal is with that.
But when I restarted the workstation, it requested an IP address from the DHCP service, but one was never released. Why is it ignoring these requests?
