  • Hi WLID1996.

    The HTTP error code 503 means that the server is currently unable to handle the request due to a temporary overloading or maintenance of the server.
    There could be several different reasons for this error: first of all, examine the "System" log in the Windows Event Viewer as well as the IIS and SharePoint logs.

    Bye.

  • Several things you can do.

    Start up IIS and make sure the application pools are started.  If not then start them.

       If pools don't restart, it sounds like a service account has password issue or has expired.

    If password have expired or changed, then SharePoint central service accounts need to be update, if they have changed.
