Yes, we are using lsclient.exe via the .vbs login script.
I have lowered the wait time on several of the items, but it doesn't seem to matter at all.
In the Service status section of the dashboard, it shows:
Scans: 1
Started: 9/13/2009 2:15:05 AM
Polled: 10/1/2009 10:46:30 AM
I would expect that scans count to increment occasionally, but it has never gone up.
