It's been since march, i have an office that was running perfectly before we renovated. Now we are having nothing but random freezing issues and machines locking up while they sit. only thing extra we had put in the server room is a sonos system for music and a air duct to get hot air out and a thermostat.
I am the network admin trying to narrow down issue. You come to the machine, its on and has power, by moving the mouse and hitting keyboard no video will display. No key seq like crtl alt delete with work. After one froze and i was there I hooked up another keyboard, mouse(usb), and new monitor, all new dell vostro's. still nothing. funny part is it is NOT a pc issue. I brought them back to my shop and they ran for a week with no issues here just sitting on the desktop, video came back fine every time. It has to be something in that environment? Some pc's are fine and others are having nothing but issues. I even put new temp pc's in their place and the temp pc's have issues (same issues) while they are in that environment but not if they run at our shop?? All computers have avg business edition 2012 or 2013.
All they do is rdp into our ts and run 1 program, the sessions always stay up but the application which depends on sql may freeze, or really mean hang. in the mean time i had made up a batch file that i wanted them to run while they were waiting for the application to respond at the main location where the server is and 99% of the time response is 1ms. we have allocated 40gb to the sql server and 18gb to the ts for about 60 users total in all 3 locations. I and the other company that we use for software has gone over server, memory, paging, resource monitor etc and cant find anything?
More troubleshooting- we checked(cable tested) and labeled every wire in main location and made sure it was dhcp unless a needed static and we get no ip conflict errors on any machine.
one of my techs is there right now and at least 3 machines have black screen, machine is physically on, hard drive spinning but no video. mouse and keyboard have power but machine does not respond. we have remote on these machines but at the same time it shows offline and we cannot connect to them.
Sometimes the machine freeze in their remote desktop session also?
