I have a problem with my windows XP. I was able to set up a network through my routers and was able to connect to everycomputer no problem. about a couple of weeks ago i took my laptop to work and ever since then my laptop DNS is shut down the only way i can access other computers and they can access me is through IP addresses. I still have a functioning network and my internet is still up.. i still get an IP from my router but my DNS only to this computer is shut down.. can U Help Me!!!???
