Does anyone else have problems with the DNS service in windows XP? If I
leave my PC sit idle for a few hours, the DNS service just stops working. I
can ping addresses on the network by IP address, but not by name. I watch
the port with a sniffer and DNS queries are not sent from the PC. If I stop
the DNS service and start it again the DNS service then works fine. I have
the home edition of XP, and am using the default settings for the lan card.
They include getting the DNS server from the DHCP server.

Is there any way to debug this problem?

Thanks

Don't know if this will work but it's worth a try: I used Device Manager
and went into the properties of each device that sustains the internet
and network connections. If there is a power management page, change
the settings so that the device is not allowed to go into standby.
 
Thanks for the response. I already tried that step though. The LAN card
does have a power down setting, but it is disabled. I am pretty sure it is
not a hardware problem. Even after the system sits idle and the problem
occurs, I can still ping other IP addresses using the address. This tells
me the hardware is still working. It just does not work when I ping by name
or do anything that requires DNS resolution. Also stopping and restarting
the DNS client service fixes the problem. I don't need to reset or restart
any of the hardware to get it working again. Is there any software setting
that could cause the DNS client service to just stop working after some
amount of time? Any other Ideas out there?

I have my router handling all of that and use my ISP's DNS servers. Also
have it set to renew every so often so that the DNS info is kept current.
Sorry, out of ideas. I hope you get more suggestions. May want to post
this over in the windowsxp.network_web news group to see if they
have any ideas too.
 
Thanks for the suggestions.
I am using a router as well, the router logs me in to my DSL service, and
obtains an IP address, and DNS server addresses of my ISP. If I tell
windows to get it's DNS server automatically, it ends up with one address in
its DNS server list. It is the address of the router. As an experiment I
changed the DNS settings to no longer automatically detect the DNS server
address, and to specify using the 2 DNS servers that the router always gets
when it logs in. This seemed to keep the DNS client service from dying.

My ISP doesn't seem to have the windowsxp.network_web group on their news
server. That's why I posted here.

Thanks again.

Check with your ISP for the IP numbers of their DNS servers. These can be
added manually to your router's configuration.

Also, you can access all of the Microsoft newsgroups by adding the server
msnews.microsoft.com to OE. The server is available to anyone with an
internet connection, regardless of ISP. OE will setup the default values for
ports. It's okay to use those values. There's no password required to access
the groups.
