Are these client machines running PNAgent or is it a Citrix Desktop running PNAgent? Did you configure the PNAgent Site in the Access Suite Console? Remove Prompt, and select SSON only? You can also try deleting the HKCU\Software\Citrix\Program Neighborhood Agent key from the affected user's profile.

Hello, I upgraded our Farm last week from MF XPe 1.0 to PS 4.0. The majotiry of our users use the PN Agent with Passthru Authentication. After the upgrade everyone started getting prompted for a logon. I look at properties of the agent and "Prompt User" is the only option available. We have not upgraded the client, we're still running on PN Agent 7.1. Does anyone have any idea what has happened?
