DNS problems on Windows 2000 Server
Posted on 2005-03-17
We are replacing a failing Windows 2000 Server, by installing the software and migrating the data to new hardware. We backed up all files (except system files in use) to NAS storage, then copied all files to the new server hardware.
We then installed a fresh install of Windows 2000 Server, created the users, groups, shares, etc.
The only problem we are having is that this server can not connect to the Internet, due to DNS issues. This is a single server environment, connected via a Cisco PIX 506. The old server can still connect to the Internet (but has data integrity issues related to failing hardware, so it is not in use at this time), but the new one can not. We can ping the pix, so we are connected. Also, we are not connecting both old and new servers at the same time, but moving the network cable between the boxes.
DNS appears to be set up the same, but I am not an expert with DNS. How can I check and confirm that all settings are the same on both servers, so that the new server will connect?
Is there a function of the PIX that can detect that the IP address of the server is on a different MAC address, or something similar? Thanks for your help!
