We have some users who have their account locked up every morning. They have these commun points:
They are using Windows 7 with service pack 1 and all updates are done.
They are using Outlook as email client with an Exchange account.
Details that might interest you:
Same troubleshooting have been done and they are not in the same branch but on the same domain.
We have reinstall from scratch the computers but the problem reapered the next time they logued in the system.
We have cleared the windows vault, cleared tempory files in the temp folder and temporary internet files and used disk cleanup.
We have used the delete feature in the internet option cheching everything.
After unlocking the account in Active Directory, we asked to reboot and to log again and the account is not locked. If it's not locked it remains ok for the rest of the day but we noticed that when account is locked is when the user log on the system when they get in the office to start their shift.
A logon script is used but it cannot be the cause or else everybody would have the same problem.
I do believe there is something between Active Directory and Exchange but cannot determine what it is.
Any suggestions ?
