I'm trying to get our Net Admins off there ass and help me troubleshoot a Network/Systems issue we are having.
We have Outlook clients on one subnet that experience long loading times with outlook and long times using UNC path and intermitten disconnects with RDP sessions.
The problem is the Net Admins just ping the gateway and machines and see 1ms reply and think ok not a Network Issue. The switch is one hop from the core (Virtual INterface) so no WAN or other routers involved.
My argument is that the network could be slow but still see 1ms ping reply times because of TCP Error Correction?
I havent read about it for a long time but when you ping something and packets get dropped, doesent the machine just send another request to retransmit the same data, adjust the window size and receive the data? Because it's fast just means it has no hops and is local. I would imagine even small errors like this could be retransmitted and reasembled in that time but still be too slow for certain apps that need to authenticte to multiple machines but fast enough for the internet, OWA and instant messanger exc.
Can someone give me a more technical explanation as to how the ping response and TCP work togethe?
