DNS best practices

[jono261970]

Hello,

I have recently set up win2k srv AD and DNS. I have been experiencing some strange events. For example one computer keeps on losing its dynamic IP + DNS and replaces them with another IP and our ISPs DNS. Although the IP is still in our subnet this drastically slows the machine down.

I have noticed that quite a few workstations have the same name as a user account - would this cause a problem?

thanks in advance

Has this been going on since day one or has something changed? Are the servers set up with fixed ip's? Ipconfig /all on machines that are good and those that are bad, how do they compare? Good luck.

Hi Glen,

This has only just started to happen. We had a bad week a couple of weeks ago with our electricity. We sustained several spikes and deep sags which knocked out our server four times. Luckily it came back up on each occassion. I have since installed a UPS for the server and switch.

I had to change a computer's IP address again this morning. If it happens again I shall just assign a static IP outside of the pool but on the same subnet.

The server does have a static address. Our DHCP pool for clients is from 192.168.1.30 > 192.168.1.60.255.255.255.0.

On bad machines the last octet is always over 100, for example the computer I amended this morning was 192.168.1.105:255.0.0.0.
I choose ipconfig /renew and it assigns a vaild IP and subnet and the computer is just fine.

Strange I know :O)

cheers
