ORA-12500 error

Hi,
Get ORA-12500 "TNS:listener failed to start a dedicated server process" trying to connect
I'm using 8.1.5 on NT
I can connect locally to my 8.1.5 database using svrmgrl and exp, but not with us/pw_at_orcl. Connect a/b works, connect a/b_at_orcl gives ORA-12500.

It was working fine the past year until I recently shutdown and started the database.

I checked possible problems found in Metalink notes, all with no success: I stopped all extra programs (Web Server, discoverer...) to clear up resources
I changed init.ora to have the instance use less memory I increased processes in init.ora
There are no warnings in NT Event Viewer Doesn't matter if I start the listener with either NT services or lsnrctl NT listener service is running as system - no change

Is this fixable through SQL*Net or the database? My next thought is to uninstall and reinstall SQL*Net. Might that help?
