Exchange 2010 - Two periods a day system response time slows down

I  have a client who's connection to Exchange 2010 via internal Outlook clients slows down to a crawl sometimes around 11am to noon, and/or around 1pm to 2pm.

I check of the Exchange logs and it's event viewer is revealing nothing.  Connections to network shares, etc, around the same times are normal.

What else should be checked in the network?  I'm still waiting on information from the client to see if Backup Exec or other culprit is running during those times.

Any help would be appreciated.

I would bet my many on windows updates -
Are you using WSUS? - If not - better install - will make your life and network operation much easier.

if that wont help you can use wireshark on slowed down computer - to catch the culprit

Good idea, but I can't really see WSUS pumping down updates M-F, even if every category was selected?  

And this is only affecting Outlook's connection to Exchange...
