プロキシについて(squid)

Linuxでプロキシをするためにsquidを使いました。
IEのプロキシアドレスをそのLinuxのサーバーに設定して、アクセスしてみると
以下のエラーが発生しました。

While trying to retrieve the URL: http://www.yahoo.co.jp/
The following error was encountered:
Unable to determine IP address from host name for www.yahoo.co.jp
The dnsserver returned:
Server Failure: The name server was unable to process this query.
This means that:
The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.
Your cache administrator is root.
