Shut off old server - Everything SLOWS down
Posted on 2013-12-17
Client had a Windows 2003 server with a couple Line of Biz apps and QuickBooks. I moved everything over to a Windows 2012 server. They are both in the domain, one is SERVER1 the other is SERVER2.
When I shut SERVER1 down, which we obviously want to do permanently at some point, all the applications get very slow, including QuickBooks. I have looked at DNS settings, the new server only hands out its own IP as DNS and WINS. I made sure the folders for his LOB apps are not shared on the old server, so no one can attach by accident.
Any place I could start looking to see WHY this happens? As soon as we turn the old server back on, everything seems to speed up again.
