try uninstalling then reinstalling tcp/ip (ambot kung naa nay ni suggest ani)
if windows xp:
go to start
go to run
type cmd
ug type ni: netsh int ip reset resetlog.txt
press enter unya wait a few seconds unya mugawas balik ang c prompt
type exit and press enter
then restart pc
if windows vista gani, you should be logged in as admin
go to cmd again (same first steps) pero ang itype kay: netsh winsock reset
mugawas dayun na: Sucessfully reset the Winsock Catalog
follow the same last steps
