Open Symantec Endpoint Protection Manager Console.

2. Enter User name and Password

3. In the "Server" text box, enter the IP address of the computer where SEPM is installed and the correct port
    Example : 10.0.X.X : 8443 

4. Click on Login

5. Every time the Administrator logs on to the SEPM, along with the expected user name and password, enter the IP address of the SEPM system with the correct port..

are you accessing SEPM using SEPM authentication or AD authentication?

if SEPM authentication.. can you try..

also you can try resetting the passwoed by running the resetpass.bat located under 'Program Files\Symantec\Symantec Endpoint Protection Manager\Tools\'

once successfuly run type admin/admin in SEPM console window.

Do not use the built-in SEPM "admin" account when setting up Active Directory Authentication, doing so can prevent logon access to SEPM with "Authentication Failure" error. Lockout issues can occur when changing the Active Directory account, upgrading Active Directory, changing Active Directory mode, and when removing SEPM(s) as a replication partner.

SEPM Active Directory Authentication is only supported for Admin accounts that have been created in SEPM by clicking "Add Administrator."

NOTE: The SEPM user name is taken from SEPM database while the password is taken from Active Directory for the account you specified in Account Name.

 If you have linked this account with an AD account follow the steps below....

  1. Remember the account in AD that was linked to the admin account for SEP Manager
  2. Let consider the account name you linked with is "myaccountinad"
  3. The password of "myaccountinad" is "password"

Login using the

Username: admin (would remain the same even after linking just password that gets maped)

Password: password (password of the account ("myaccountinad") which is linked to admin)

But are you using the default "admin" account or a SEP administrator account that you created?  Do you even have any additional SEP Administrator accounts?  Does this affect all accounts?

Oh, and don't forget, the username is case sensitive!
