Load Balancing IIS website in Windows Server 2003

[Motiv]

Hi all,

Thanks in advance for reading this. I would like to load balance our company website using Windows Network Load Balancing.

Our existing web server is Windows 2003 Web Edition running IIS 6.0. There are 10 IPs total bound to the machine.

Lets say companywebsite.com is 216.182.98.50. 15+ other websites reside on the machine using each a unique IP address.

There is no need to load balance the other websites at this time. Now to my question:

Would it be okay to use the existing companywebsite.com IP address as the Load Balancing Cluster IP Address, and add say three existing non-used IP addresses to the pool for load balancing? Would this effect the other websites using the other unique IP addresses, or should this be fine?

Thanks in advance
