    Internet Printing authentication failing with 401.5 on IsapiModule

    Reply Contact

    I'm trying to set up an IIS to allow internet printing - i'm using Basic authentication with ssl

     after connects to printer and enters internet port information i'm getting a 401.5 error on the IsapiModule

     

    (the user is then presented with a second login box, which, if they login twice after about 5 mins are told "Printer Installation Failed the handle is invalid"

     

    i've tried changing the DefaultAppPool to Classic pipeline mode but this has made no difference - has anyone any ideas?
