I am new to Oracle and I inherited to clustered windows DB servers. This is Oracle 10g with RAC on Windows 2k3 x64

I have no idea what happened to break it, came in in the morning to complains the DB wasn't working.

When I do a crs_stat -t I see that several of the DBs are offline. When I try to start them I get CRS-0223 resource placement error. No amount of restarting or rebooting corrects this.
If I try to bring up the database via the EMC I get PRKP-1001 and CRS-0212 and it says resources are unregistered.

I don't know what to do at this point. Any help would be appreciated.
