I just upgraded MICC 8.1.1.- to 126.96.36.199 all appeared to go well until i tried to login in to run some reports
The web paged showed an error advising the user didn’t have permission
The issue appears to be the account used for the application pool had been reset to default.
In default this is set to local system. It needs to be set to the account you are using for your services.
Right click on the PrairieFyre application pool and choose advanced settings. Scroll down and change the Identity.
