When my clients are trying to open the Qlikview Document , this error appear:
iis_authenticate = could not be opened
It just starts Last Week ,
I have Allowed Anonymous Access to QVajax and Scripts Folder .
We got this error two times and with two different reasons .
For First Time : It was due to the , CAL liscence Allocation to USERs was fully done .No CAL left for new user to Allocate .Then I removed some of the users(Who were not using the application from long) from CAL from QMC and it worked .
For this Open QMC-->Liscences-->Go to Client Access Liscence(CALS) -->Then Check User name is there or not if not add that user name .
For Second Time : Qlikview plugin version was not latest on one user's machine .So instaling the latest verion of Qlikview Plugin resolves the issue .
