Transfer request from default server to new server

[sjohi3]

Hi,

I have a situation.

I have two Sun Servers.

1. I have a server-A which is known as apache server,
sendmail server, DNS primary.... etc.. and it also
has softwares like Waisgate, Linkscan etc...( with
licenses).
since it recieves a lot of calls it has become very
slow and breaks down very often.

2. We have three areas like a.com, b.a.com, c.a.com,
when public accesses the url: a.com it goes to the
public page.

when department b accesses --> goes to b.a.com page

when department c accesses --> goes to c.a.com page

3. Now i want to separate this apache from server-A and
install it in the new server-B...(keep this as a
webserver)and it should accept all the loads. and the
previous setup should be there as it is.

How do i do that?

It will be very helpful for me if i get some
suggestions

Thanks,
