Why do people automatically assume that if you are having problems its "got to be your computer"
Because it's process of elimination.
If some people are getting disconnected and some not, it can't be the LC servers, as then ALL people would be getting disconnects.
But I know what you mena about the DC waves, I got hit by one today, and it took out all party healers.
My entire guild had to run for their lives.
Might not be LC servers or their computer, it could very well be servers that your connection jumps to on its way to LC.
I'm guessing that the lastchaos website is hosted on the same server as the game so do this:
open command prompt:
Start > Run > Command
Start > Programs > MS-DOS Prompt (Win9x)
Start > Programs > Accessories > Command Prompt (WinXP)
This will create a file called trace.txt in the directory you're working in.
After this, you can open it up in any text editor, and copy & paste.
Type: notepad trace.txt after you do your traceroute, while still in the command/dos prompt.
This should open the file.
As for the directory it's in, it should be in the dir as indicated by your prompt,
which should look something like:
if not, type: prompt %p
This will change the prompt to show what dir you are in.
Use explorer to go to that dir to find the file.
Then post the results here and hope someone with server and related knowledge comes and helps.
