Mark,
Even thought I have dhcp enabled, the two computers get similar ip addressed: 192.168.1.100 and 192.168.1.101. So I see no reason to disable dhcp. Other than that, it should work but id does not. I am probably missing something very simple. I will keep trying.

Thank you for your suggestions.

>Dmitry,
>set up both pc's with the same workgroup name, and also have the ip addresses similar for convience, try 192.168.2.101 and 192.168.2.102. take off dhcp if you are using it. make sure that the other settings are also set, subnet etc. if you are on as the administrator on both there should be no problem doing as someone mentioned ip\C$ to connect to the admin share. XP SP2 may have turned off pinging the machine and there may also be other setting set, if you have SP2 installed turn off the firewall and see if you can get in that way. Also the guest accounts may be deactivated if you are trying to go in using these.

>>I login into both computers as an Administrator (without entering any password), yet I still can't connect from one to the other using the command \\IP at the command prompt. I think in your case you actually have a user name and password when you log into the Win 2000 box. I have not set up a password when I installed the OS. So when I boot up my PC, I simply click Ok on the logon window.

>>>Like Borislav said, that IP you mentioned might be the router. But, I don't think it is. I think to get the routers menu, you actually go to a browser and enter "localhost" or something like that. The book tells you exactly. The logon is either Admin or administrator and the password is blank.
