Domain controller inactive in arcsight
In the pass week, I updated controllers domains ( Windows server 2003 to windows server 2008 R2). Since this moment I don't receive logs, and the domains controllers I see inactive.
The conector of windows where arrive the controller domains is operative (up) - and other controller domains that I don't updated are operative too.
The problem is only in the domains controllers that I updated the SO.
What can I to check? What Can I to change?
Please help me.
