shared drives

Hi,

I am trying to set up my win98 machine as a share to a win2000 server. I can see both machines in Network neighborhood and My network places. I can access my drives from my win2000 server to my win98 machine but when I try accessing the drives on my win2000 server from my win98 machine I get the following

enter network password

resource \\comp. name\ipc$
password ???????

What password is it looking for? I would appreciate any help.
