By reading some sections of latest version of BIP Admin Guide, I found that two sections have been duplicated in the guide. I think it's a mistake. Here is the details if someone from SAP wants to correct it :
Business Intelligence Platform Administrator Guide
SAP BusinessObjects Business Intelligence platform 4.0 Feature Pack 3
188.8.131.52 Services and servers
3.2 Services and servers
I think section 3.2 should just reference section 184.108.40.206.
Hope this helps
