I have 2 servers (Both: Windows Server 2008, Dual Xeon 2.8Ghz, 32GB RAM, 8 x 15k SAS Drives). One of them is a DC / Web server / Exchange Server, the other is a SQL Server (2008).
I have a 48 port Netgear GS748T Gigabit switch.
When I ping from server to server, I get ping times <1ms, great, but when I ping from a PC, I get varying pings from the occasional <1ms to >500ms!!
If I log into either server and look at Task Manager, CPU usage peaks at 20%, memory usage is 100%, but I am led to believe this is normal as Exchange will just use as much as you have, and release it when requested. Network usage peaks at 1%.
I really don't understand how the ping can vary that much. I know I am giving very little info, but this is all I know, I apologise, but can anyone help?
In response to question, I have pinged by both IP address and hostname, no difference in ping times.
