First of all: There is edit button, we don't accept doubleposting.
Second: There is no need to post every day, just do what we told you and/or what you want and give us results, it's no IRC, we don't need "Quick updates", rather longer explanation what you found. We are in no hurry, and so far you only make it harder for yourself since you don't explain exactly what is going on, assuming we will guess rest.
I would never of classed what i did was double posting, double posting to me would mean posting the same information twice on 2 separate occasion to try and get a response, which i added 2 separate bits of information to try and help with the problems i am having,. so i will remember for next time and i will see that as me been told off.
as for anything specific i apologize if i have missed any information that has been requested from people but i can't see anything that anyone has asked that i have missed.
If you type "netgraph 1" at the console of the clients, it will display a ping graph at the bottom of the screen (on LAN it should only be a couple pixels, flat). If there are any black lines, that means there was packet loss. I'm guessing these "jumps" are caused by packet loss. I honestly doubt any hardware you have would be slow enough to have lag for performance reasons, as payl suggests, unless some other process is taking up all the CPU. You could monitor the CPU usage, just to be sure, though.
I Have attached a image of the netgraph as mentioned,. the 3 spikes are when another player is joining the server.
I possibly could of gave you this before be didn't really think., but here are the setup up of the Server and PC.
Server
Intel Core 2 Duo 2.33Ghz
4.00GB RAM
Intel Gigabit Network Card.
Windows Server Enterprise 64-bit (Service Pack 1)
Windows firewall Disabled and no 3rd party firewall installed.
PC
Intel core i3 1.8Ghz
4.00GB RAM (3.2gb Usable)
Intel Gigabit Network card
Windows 7 32-bit (Service Pack 1)
Windows firewall enable but blocks all connections that aren't in the allowed list.
The Switches are configured by the local authority so can't comment how they are configured. If we could pin point that it was the switchs then we could get them out to tweak some settings for us.
Thanks for help so far. I am getting closer to the solution Im sure.
