Remove DNS numbers from w2k server

help, i installed an w2k server (application server only) local lan users can use shared drives but wan users can only see the drives but can not map to them.

i checked my i/p numbers and their all good BUT in the DNS setting the loop-back i/p istheir (127.0.0.1). i have no idea how it got their i tried removing it but it keeps showing up.

i think this is my problem.

i need to remove the DNS numbers and have it stay away.

thanks
peter
