We use a billing software tied to a sql database. We have some users who are no longer able to login to that software. It will time out when connecting to the database. They can login to their workstations just fine. According to the logs, they have bad passwords. But what is odd is that they cannot login from their own workstation but sometimes they can login from another one or a laptop just fine with the same credentials. I have created new passwords but that did not work. I can add a new user to the domain and also the software and that will not work. One lady was right in the middle of billing and she got kicked out of the software and was unable to connect again. Gave her a different computer and she was able to login and do her billing. I am at a loss as to where to look for the issue. Seems like a computer/dns issue but like i stated, you can add a new one to the domain and it may not work. Any ideas where to look?
