### `Internal error: unable to establish probe connection` Appears When Running Jobs on a Managed Host

Description:

  When you run jobs on a managed host, you might see the following error message:

      Internal error: unable to establish probe connection

Cause:

  This message appears when you run jobs on a managed host that is managed by more than one Change Manager server.

Solution:

  Ensure that the managed host is managed by only one Change Manager server.

  To change control of a managed host to another Change Manager server, perform the following steps:

  1. Remove the managed host from the current server.

  2. Add the managed host to the new Change Manager server.

  3. Create a shared profile for the managed host.

  4. Run Set Up for Install or `changemgr setup` for the managed host.

  5. Type the `boot net - install` command at the OpenBoot prompt of the managed host to perform the initial installation.
