Os x lion keeps dropping connection to domain controller

Question

What is the story with OS X Lion. It keeps losing connection to a Windows domain controller after a restart. Ive come back to my lab after the weekend and nealry 30 out of the 50 imacs that were on the domain are saying domain controller not responding resulting in network accounts unavailble. Meaning NO-ONE CAN LOG ON.......!!!!!!!!
ITS A JOKE.....
I hold out no hope for an official reponse from someone from apple to address this issue. In the meantime Ill just keep unbinding them, deleting the computer object from AD, force replication on all DCs', repair permission on the HD of the iMAC, rename it and rebind it to the domain. Then I will do that for all the other 29 iMACs that have lost connection to the domain....BECAUSE I HAVE NOTHING BETTER TO DO WITH MY DAY.....!!!!!!!!!!!!!!!!!!!!!!!

Hello fellow Mac users,
The root cause of this issue will be different for everyone as it’s usually some rogue app or process that isn’t working properly. In my case it was a Symantec utility called ‘SymUIAgent.app’.
Follow these steps to identify what specifically is causing the issue on your computer
Save the code on this file to your desktop using the filename id_issue.py: https://gist.github.com/iMerica/8928556/raw/73832a509de4dc5394cf1747b997ea1bd1b0 ff4e/identify_focus_issue.py
Open Terminal.app (Located in /Applications/Utilities)
In Terminal, cd to your Desktop using cd ~/Desktop
Run python id_issue.py and just let your computer sit for a few minutes (assuming the issue is happening within a few minutes/seconds).
Basically this code gets the current active window every three seconds and prints it as standard output which you can view in Terminal. Once you find the offending app, search on Google for specific steps on removing it.
I hope that helps!
