Could anyone tell what the following error means. I get this error on the
server console.

3/03/2004 14:01:23 : ACLCHECK-4.70-13
Severity = 1
Get IP addr failed for hostname: www.(web site name).ie, .com etc.

All of these addresses are configured in one of my access rules which my
users have access to.I can still go to the website when the address is
entered at the browser. Any ideas?

Thanks in advance,
