DNS config for load / availability balancing

[Phil]

Background - 4 Win2K servers, all nameservers to the internet, all AD with a
single domain + 3 sub-domains in the forest. All are used as email servers too
with MX records created giving priority as required. Only one is using IIS for
multiple websites using host headers.

Requirement - to copy all websites [all have static content] to the other 3
servers and have alternate IP addresses served up such that if one server is
unavailable or off-line for any reason, an alternate is provided as with email
servers, is that possible? I haven't found how to do it with CNAME records. If
not possible, can anyone point me in the right direction to achieve this please.
Cheers, Phil
