I've got a 3300 ICP R.7 that I can login to, but once I choose System Administration Tool gives me the message "Your session has timed out. Please exit the application and log in again".

I was working in the ESM and left my office to take care of something and when I came back the system had timed out. This not being unusual, I closed the Sys Admin Tool and exited the ESM login so I could log in again. I then received this message. I closed the browser out and tried again and still the same message. My browser is IE7. I tried clearing my Cookies, temp ie files etc, still nothing. I have tried other users workstations, still nothing. I even reset the ICp and this did not correct it. Using a different browser is not an option since only IE6+ is supported. Any ideas would be appreciated.
