This is my first post to this forum, I've searched my issue extensively and put over 20 hours into trying to fix this issue thus far. I am not an IT expert and I apologize if I am doing something incorrectly or use the wrong vocabulary.
Anyways, onto my problem:
About a month ago we've been experiencing extremely slow ping, up and down rates, 1000ms ping, .05 down, .01 up; however it lasts about 1-3 hours, never actually disconnects, and then goes back up to normal service rates of 15 down 1 up, etc...
I've worked with AT&T extensively and eliminated any line or hardware issues on their end.
Our network is run through a server running Small Business Server 2011 with two NIC's, one for static local ip's and one for our remote access server. Our DNS is routed through it as well.
I've begun to suspect that something with the server is either being flooded or stuck in a loop, causing the server to use all of our available bandwidth. I started running WinShark program and find that we're getting over 5000 packets every ~20 seconds. I don't know if that is high or not, but it seems high.
Please help me in figuring this out or at least try to understand this issue.
Here is a screencap of my WinShark report:
Thank you very much,
