Find Computer not working - Deployment Server 6.9 SP6

Hi,

We were running Altiris Deployment Server 6.9 SP4. The "Find Computer" icon does not find computers that are in the Console.It returns a "Computer not Found" message. We upgraded to Altiris Deployment Server 6.9 SP6 and it is still not working. Incidentally, the "simple search" does work however the "Find Computer" icon is what our Helpdesk staff prefer to use.

Have you any suggestions as to what the problem might be?

Thanks..

Altiris Deployment Solution 6.9 SP6 running on Windows Server 2008 R2 64-bit.
