I have been trying to figure out a problem since over a year and today by fluke I think I stumbled on something. I have a program installed on my server which I access from my office pc. Connecting to it is very slow. Today I lost internet connectivity because of provider problems. I connected to my server using remote connection and it instantly opened while before it took about 10 seconds. My internet came back on and it was slow again. Disconnected internet to my 3com gigabyte switch box and again opens instantly and my software I mentioned earlier also opened right away. So If I disconnect internet to my system access to server is great as soon as I reconnect internet all goes slow. Server have server essentials 2012. Main computer is wired to switch on windows 8.1 Tried disconnecting both anti virus and firewalls on both computer and it doesn't make a difference. Where can I look? Internet speed is not a problem as it tests to 52.63Mbps download and 48.93Mbps upload.
