Can't maintain DNS ability?

I have a LAN with 5 pcs running WIN2K through a Linksys router with static IPs and DNS servers assigned through TCP/IP properties in Win2K.

All is well EXCEPT for one pc which has started to sometimes lose its ability to connect to the internet, though it is still connected to the LAN???

After a reboot, it will work again, but then suddenly loses its ability to connect at some point.

It appears to me to be a DNS issue; the pc sees the router.

I tried FlushDNS, and also added the registry hack to do the same, but that has not resolved the problem.

Am I going down the wrong path here?

Any ideas?

Thanks,
Aiko
