Question : WSUS client pc have no automatic update icon displayed

I just installed WSUS 3.0 SP1 on my server. I created GP for automatic update and point the update service to http://my_server. I am able to see the client pc in Unassigned computer container and it indicates that there are 14 updates needed. However, in client pc I don't see the automatic update icon displayed.

Answer : WSUS client pc have no automatic update icon displayed

the computer has not yet reported...befor this is not done...it will not receive any updates.

Try this command on the client:
net stop wuauserv
net start wuauserv
wuauclt.exe /resetauthorization /detectnow

If this does not help...try this here:
