Troubleshooting the hosts file
NOTE: If you have MSN messenger installed check for file called hosts.msn and if exists, edit this one instead of default Windows host file.
If you have a problem connecting to the server ( account and password do not match ) Try this:
Troubleshooting the Hosts method (Live client, for PTS client substitute L2testauthd.lineage2.com for L2authd.lineage2.com, below)
1) Make sure your spelling and Capitalization is correct. Use only letters and numbers for your username and password. If you still get the error continue on to 2.
2) In a command prompt type "ping L2authd.lineage2.com" If you see "Pinging L2authd.lineage2.com [206.127.151.66] with 32 bytes of data:" then you are connecting to NCSoft, continue on to 2a. If you see "Pinging L2authd.lineage2.com [Server_IP] with 32 bytes of data:" then you are connecting to your server, skip to 3.
2a) Check that your "hosts" file contains a line with "Server_IP L2authd.lineage2.com" and only one instance of "L2authd.lineage2.com". Also check that you have not accidentally created a "hosts.txt", it should be an extensionless "hosts" file. Try to connect, if you still get the error, continue on to 2b.
2b) (Windows XP only) *NOTE: As this problem is usually caused by spyware "hi-jacking" your "hosts" file, it is good idea to run spyware removal software before making this change to avoid the spyware undoing your changes. Open Regedit and open the following key "HKEY_LOCAL_MACHINE/SYSTEM/Current/ControlSet/Services/Tcpip/Parameters". Check that "DataBasePath" contains the following data "%SystemRoot%/System32/drivers/etc", if it does not, change it to the aforementioned data. Try to connect, if you still get the error, continue on to 2c.
2c) (Windows XP only) In a command prompt type "ipconfig /flushdns" Try to connect, if you still get the error, continue on to 2d.
2d) (Windows XP only) Open "Control Panel", then "Administrative Tools" then "Services". Double click "DNS Client" click "Stop" and change "Startup type" to "Disabled". Try to connect, if you still get the error, continue on to 2e.
2e) In a command prompt type "ping L2authd.lineage2.com" again. If you see "Pinging L2authd.lineage2.com [Server_IP] with 32 bytes of data:" then you are connecting to Your server, continue on to 3. If you see "Pinging L2authd.lineage2.com [206.127.151.66] with 32 bytes of data:" then you are still connecting to NCSoft, try setting up your "Hosts" file again.
3) Try to connect, if you still get the error set up the hosts file again.
