-We are getting an "Installation Failed. The Printer name is invalid" error when connecting over http (http://printserver/printers
) from Windows Vista clients attempting to install any IPP printer on a Windows Server 2003 printer server with SP2. We get same results on another print server that has R2 and SP1 on it.
-Windows Vista clients are students PCs not connected to our domain but are authenticating to the print server via their Active Directory user accounts through digest authentication on IIS.
-Staff Vista PCs that are on the domain have no problem installing IPP printers on the same print server
-Student XP PCs not connected to the domain are able to install IPP printers just fine on the same print server
-We have tried unchecking Protected Mode from the Local Intranet Security setting in IE7 before trying to install the IPP printer, but got the same error. We did get the IPP printer installation to work on 1 PC after doing this, but it failed on other PCs as well as the same PC after deleting the printer, rebooting and trying to install again.
-Student PCs are able to successfully install a printer by connecting to the the server and the printer share name. \\printserver\printershare
name However, this is not an ideal solution as the user will need to re-authenticate to the print server before they can print after shutting down or logging out.
