When you deploy a PowerBuilder Web Forms application to IIS 7 or later, the application is deployed to a PowerBuilder-specific application pool named PBAppPool. PBAppPool uses the default application pool identity, which is NetworkService on IIS 7, and ApplicationPoolIdentity on IIS 7.5. However several Web Forms application features, including the creation of permanent user accounts, SSL authentication, and DataWindow Print and SaveAs commands, do not work with the default IIS 7.5 application pool identity. To enable these features, you must change the PBAppPool application pool identiity to NetworkService.
For a description of the procedure to change the PBAppPool application pool identity, see “Configuration requirements for Windows Vista and later.”
