Teamspeak Issue!!

HI ALL,
im having issues w/ teamspeak and running my server on my lan... i have the server running but my other computer has a socket error 11004 when trying to connect. we used to be able to play games until i got my new computer and ever since we cant use the lan option on games or anything for that matter...does anyone have any know how to fix our problem?

Socket error 11004 - Valid name, no data record of requested type

=> host-name resolution may have failed, you may try to enter your server's ip address instead.

so instead of using yourtsserver.com:8768, use 123.456.789.123:8768 (substituting the IP address of your ts server for the example).

still not working...we cant play games on the lan nemore either. we can join a seperate server but not a server im running. still says cant connect but it will connect to a another inteties server
