RAC problem -- PRKP-1001 and CRS-0212

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.

Symptoms - database offline, start fails with errors CRS-0212 resource <resource name> is not registerd
Attempts to start from EMC result in PRKP-1001 and CRS-0212 errors together

Cause - database has been unregistered from the RAC cluster

Actions required -

1 - remove the unregistered database from the cluster configuration
D:\...\crs\BIN> srvctl remove database -d <database name>
Remove the database devdb? (y/[n]) y

2 - add the database back into the cluster configration using the following steps
D:\...\crs\BIN> srvctl add database -d <database name> -o %ORACLE_HOME%

D:\...\crs\BIN> srvctl add instance -d <database name> -i <database instance> -n <host>

D:\...\crs\BIN> srvctl add instance -d <database name> -i <database instance> -n <host>

D:\...\crs\BIN> srvctl add service -d <database name> -s <service name> -r <host>,<host> -P BASIC

Symptoms - database offline, start fails with errors CRS-0212 resource <resource name> is not registerd
Attempts to start from EMC result in PRKP-1001 and CRS-0212 errors together

Cause - database has been unregistered from the RAC cluster

note: do this from within the DB's environment

Actions required -

1 - shutdown the database, stop each instance

<database> (ex: navytap)
sqlplus / as sysdba
shutdown immediate;

2 - remove the unregistered database from the cluster configuration
D:\...\crs\BIN> srvctl remove database -d <database name>
Remove the database devdb? (y/[n]) y

3 - add the database back into the cluster configration using the following steps
D:\...\crs\BIN> srvctl add database -d <database name> -o %ORACLE_HOME%

D:\...\crs\BIN> srvctl add instance -d <database name> -i <database instance> -n <host>

D:\...\crs\BIN> srvctl add instance -d <database name> -i <database instance> -n <host>

D:\...\crs\BIN> srvctl add service -d <database name> -s <service name> -r <instance>,<instance> -P BASIC
