Our small office is running Quickbooks Premiere 2003 Accountants Edition, five user version. We run in multi user mode and have four users set up. When I arrived in the office this morning, I could not access my QB file. Regardless of which user/pw combo I tried, none were valid. When I eventually managed to access my file, I found that all four of the users/pws had been changed. The users were the same, but the pw for each had become a random combination of six letters and numbers. I tried to change one, but the change did not 'take' and I must still use the random password.
I am completely bewildered as to how this could have happened. No one was in the office over the Independence Day weekend and no one used the computer system at all. How could the passwords for all my accounts have changed themselves?
