Service Connections

I have 3 ArcGIS server connections set up in GE manager. All 3 have different user names and passwords because they are used for different sites. The problem is I just created a new site and when I tried to add services only one of the connections (the wrong one) is visible and doesn't have access to the data I need. How can I see all 3 connections under "Search" so I can choose the one I need?
