Mapping drive – XP to DC secured folder – What Authentication used?

1) Using NET USE or WSHNetwork.MapNetworkDrive (vbscript / wscript)
2) XP Pro (SP2) in a workgroup, not in a domain.
3) Mapping drive to a secured folder within Netlogon share on a DC, in a domain

When we pass name/pw creds, does it use Kerberos or NTLM (V1 or V2)?

If not Kerberos, is there a way to force it to use Kerberos?

thx!
