Forms&Reports 6i for WindowsNT refused connection to Personal Oracle 8i for Win2000

[Gayatri KNA]

I feel dumb even asking this but I desperately need help.
I installed Personal Oracle 8i for WINDOWS 2000 in the D-drive of my home PC and then installed Oracle Forms & Reports 6i for WINDOWS NT in the C-drive. My OS is Windows 2000.
As expected, Forms and Reports refuse to connect to the Oracle database. I have tried everything to make it work and want to know if there's ANYTHING that can be done to achieve Forms & Reports connectivity. I am unable to secure a CD that contains Forms & Reports 6i for Windows 2000 so have to make this work if there's a possibility that it would. Is this connectivity even possible?
Thanks in advance for your help.

To give some more information, I keep getting the errors, ORA-12203 and
ORA-12154. Plus, I am not even able to logon to the Oracle DB from the cmd prompt in the C-DRIVE! Any help?

First Oracle Error message.
Second Oracle Error.
I expect it to be a tnsnames.ora thing myself, and that seems to be confirmed in those two links. Also maybe the database isn't running at that time.
Good luck.
