Complete the following steps until the problem is solved.

  • If you have direct access to the server, complete the following steps:

    1. If possible, log in to the system and verify that all applications are running without hanging.

    2. Restart the server.

    3. If the problem recurs, make sure that every newly installed software is configured correctly.

    4. Contact the vendor or provider of the software for technical support.

  • If you have remote access to the server, complete the following steps:

    1. If possible, log in to the system and verify that all applications are running without hanging.

    2. Log out of the system and log back in.

    3. Validate the network access by pinging or running traceroute to the server with a command line.

      1. If you are unable to get a response during a ping test, try to ping another server in the same server room to determine whether the problem is caused by failed connection of the server.

      2. Run traceroute to determine where the connection breaks down, and try to resolve the connection issue with VPN or avoiding where the connection breaks down.

    4. Restart the server remotely.

    5. If the problem recurs, make sure that every installed software is configured correctly.

    6. Contact the vendor or provider of the software for technical support.
