I noticed yesterday that Clients showing up offline after updating to version 2600. They all showed the same date and time 11/20/2012 11:13 AM (CST). Calling the clients and having them reboot the computer still showed offline. I drove to one clients business and restarted the client about 4 times before it came back online. They were a mixture of XP and Win 7 pc's all 32bit.
Anyone else see this behavior
