Security Software

We installed Oracle Directory Server on a Windows Domain controller server, so next to AD, using different LDAP ports.
After removing AD from this server, we are unable to login with the administrator accounts.
DSCC reports:
Failed to contact the DSCC registry
Make sure that the DSCC registry is online and listening on ldap://SWCIR0008.d.ns:3998.
Use f:/Programs/Oracle/dsee7/bin/dsccsetup.exe status command to check the DSCC registry status.

The command: f:/Programs/Oracle/dsee7/bin/dsccsetup.exe status
