I have Windows Server 2008 R2, on a Dell PowerEdge T110 II. ABout 3 months ago, my Administrator Password mysteriously changed without me changing it. At the time I suspected one of the employees in our company may have changed it by accident as a few people knew the password. In order to get a new password I was forced to re-install Windows on the Server, and this was very disruptive to our business operations.
After that I kept the new Administrator password a secret, nobody else knew it. Then, 2 weeks ago, the Administrator Password automatically changed again by itself. Since I know now that it was not a human who did this, I am concerned I may have a virus. There is no anti-virus on the Server.
Based on the above, can you suggest any other explanations and some advice so it does not happen again? Is there any other way to re-establish the Administrator password without having to re-install Windows all over again?
Many thanks,
Matt Homfray
