Need to update login info for IT Analytics

I just started working for this company a couple weeks ago and we had to change the main Altiris Administrator account password because the previous admin no longer works here, everything has been working great but we just realized that the data for IT Analytics is stale and has not been updating. I tried to manually process a cube and I get a login error. I am assuming the credentials are stored somewhere but I cannot find them to update with the new password. Can someone please tell me where they are stored??
