samba - Jul 2014 - NT_STATUS_RPC_PROCNUM_OUT_OF_RANGE while running net rpc vampire

Hi,

I have problem with migrating Samba NT4 domain to AD. According how to I 
joined Samba BDC to NT4 domain, but when i run 'net rpc vampire' command
i get this output:

DC is not running Active Directory
Fetching (to passdb) DOMAIN database
Failed to fetch DOMAIN database: NT_STATUS_RPC_PROCNUM_OUT_OF_RANGE

I don't know what's wrong. Have you any idea?

Thanks
