Force refresh of Dns on Clients?

[bigdunc]

Is their anyway I can force client machines to update their network configuration after I have made changes to a Win2k server? I don't fancy having to go round 30 odd-Pc's and manually releasing and refreshing their network configuration.

Cheers.

Thanks for the reply.

Yes, I am using AD and need the clients to use new dns servers not just flushing the cache. Immediate would be preferable but next logon would do if it is easier.
