Thanks for posting.
Let's try restaring the admin server. Open the Terminal in /Applications/Utilities/ and run the following command:
fmsadmin restart adminserver
Then, launch the admin console again. Does it still erroneously list the client?
If it does, let's make sure that Java's version order of preference is set to prefer 32-bit. Open the Java Preferences from /Applications/Utilities. Under the General tab, it should list both the 32-bit and 64-bit versions. If it's not already there, drag the 32-bit version up so that it's first in the list. Once done, launch the admin console again and let us know if the issue still occurs.
Thanks for your help it is much appreciated!
I had already taken some steps to get the client to clear. I tried restarting the admin console a number of times with no effect. (The java prefs only has 32 bit option available.)
The restart of the adminserver did clear the ghost client.
I have not had it happen again as yet. I am hoping it does not re-appear.
