Network Connectivity Consistently Drops
Posted on 2013-06-04
For the last couple of days we have been experiencing more than the usual network lag.
I blocked some of the more bandwidth intensive websites, and this did not help. I then noticed that with my initial troubleshooting that a ping –t to my router (which is also my proxy server appliance), as well as my servers (domain controllers, print servers, etc) would show a periodic timeout. This would also be evident when I had remote desktop sessions to my servers, the session would have to reconnect itself.
All of my servers are connected into the same switch in our server room, which connect into our main switch which resides in data closet.
Pinging from anywhere in the building yields the same results. I have not found anything in the server logs indicating an issue. I had our proxy vendor run internal tests on our proxy/router, and it came back clean. I have replaced the switch in our server room & data closet. Replaced cables, used the alternate data drop for the connection between our servers and data closet, and the result remains the same.
Also, we are running Server 2008 R2 on all servers, clients are running a mixture of XP, vista & windows 7.
