Domain Node is Unavailable

If a registered domain node appears with a red slash in the X Administrative Console, the node is unavailable. This could be caused by any of the following:

The domain node host is not running.
The domain node is running on a Windows computer in "sleep" mode.
The network connection to the domain node is down.
The domain node and domain controller are not running the same version of Reflection X Advantage.
The node was removed from the domain using rxsconfig, but the utility was unable to reach the domain controller to update the list of registered nodes.
The domain node is running on a system with insufficient memory. See Technical Note 2657.
