TeamSite installation on MS Cluster

System

Hi,

I'm installing TeamSite 5.5.2 (alogwith OD 5.6 and DD5.6) on a windows cluster server (Win2k SP3).
Do I need to do the installation as a user on local machine or do I need to use a domain user on both the servers?

How about the web-server? Should it be the virtual hostname or the local hostname?

Any advice, suggestions are most welcome.

Thanks
