Source:  TUI.NLM

Possible Cause:  A utility requesting TUI services is expecting a level of NUT services different from that provided by TUI.NLM. TUI will continue, but all required services might not be available.

Action:  If no further errors occur, no action is required. However, you should upgrade the TUI.NLM, NWSNUT.NLM, NUT.NLM, and the utility's NLM program file to the latest version on the server displaying this error.
