In the Test environment I am trying to login in to http://yourserver/EPA_Taskbox using the admin credentials. And it says inalid login. But in Dev it allows me with the admin credentials Any help is greatly appreciated.Thanks
Hi,

Login to the Users application and make sure your admin can login there was well and has permissions over EPA_Taskbox.
