The "vastool status" command returns the following message:
FAILURE: 219 The misc cache is missing the forestRoot setting for this machine.
A rejoin should be conducted to populate the misc cache settings properly. The rejoin should include the -f option which will use the existing computer object in AD.
You can find the original join command in this file.
If rejoining does not resolve this issue please collect a snapshot with this command.
It will create a file in /tmp that can sent to support, at this point in time a support case should be opened.
As well join debug would be beneficial with a command similar to this.
/opt/quest/bin/vastool -d5 -u username join domain 2>&1 |tee -a /tmp/joindebug.out
Please attach these two files to the case.
