I have a strange problem on my XP workstation at home. It seems that sometimes when I open a cmd window and try to reach a host I can't resolve the name.
If I ping a hostname then I get
Code:
ping hostname
Ping request could not find host hostname. Please check the name and try again.
but when I immediately do
Code:
nslookup hostname
Server: dns1.mydomain.com
Address: 10.0.0.8
Name: realname.mydomain.com
Address: 10.0.0.8
Aliases: hostname.mydomain.com
it shows dns working fine. If I then repeat the ping command expecting it to find the host it again fails the same.
I am a dns administrator and am very confident regarding how this is supposed to work. I don't see why it fails to resolve the host when it worked fine a few mins ago. I am convinced this is a problem with the workstation.
I have checked the hosts file to make sure there is nothing short circuiting the name resolution method and can see that the file is empty.
The dns server is not loaded, it is connected to the same 100Mbit switch as the workstation and there is no other heavy traffic going on at the time.
I just flushed the cache and it works again now. But I don't understand how this could happen. This setup is very simple compared to what I usually do. At exactly the same time I try these things from my Linux laptop it works fine showing that the problem appears to be confined to this workstation.
The next time this happens I will look at the actual dns cache itself (can't now since I just flushed it - Doh).
Any ideas or feedback welcome.
