Problem Connecting to Workgroup Computer

[pureplayer]

Hi, I have 2 computers connected on a workgroup via hub that run Windows XP with SP1 and all updates. One machine has Internet Connection Sharing with Windows XP firewall enabled. The other machine can connect to Internet. However, when I try to connect to the other computer, on either machine, I get the Username & Password pop-up as usual but the Username has ComputerName\Guest as its credential and it is greyed out where it cannot be edited. Password can be entered.

Where and How would I edit this, so the username can be entered, with the account with adminstrator privledges of the particular machine i'm trying to connect to?

Your assistance will be appreciated.

Thanks

. Usernames with passwords on both machines, no blank or empty passwords;
. Make as new users on Computer B the usernames and passwords of Computer A; make as new users on Computer A the usernames and passwords of Computer B
. Make sure that the XP ICF firewall is enabled only on the adapter connected to the Internet, not on the LAN adapter.
