Depending on which Admin you're talking about? If it's the regular MVM Admin, then login as FSGlobal/GlobalAdmin to reset it. If you've forgotten the GlobalAdmin password, then there's an MVM Global Admin Password rest tool that is available from support. You should open a Service Request and request it:
- Go to: http://www.mcafee.com/us/about/contact/index.html
- Non-US customers - select your country from the list of Worldwide Offices.
Log in to the ServicePortal at: https://mysupport.mcafee.com:
- If you are a registered user, type your User Id and Password and click OK.
- If you are not a registered user, click New User and complete the required fields. Your password and login instructions will be emailed to you.
Hope that helps.
