Not getting any serrver nodes in SAP MMC

Hi experts,

When I am trying to login to SAP MMC.

Here I not getting anything under the server system.

Its saying there is no items to show in this view.

When i checked the eventviewer. Its showing this error.

The SAPJ2E_01 service was unable to log on as .\SAPServiceJ2E with the currently configured password due to the following error:

Logon failure: the specified account password has expired.

Anybody has the idea where i have to change this password and for which account.

help will be apreciated.

Thanks

Manisha
