The Microsoft Windows 2000 Resource Kit�s Trustdom tool lets you define trust relationships between Windows 2000 domains and one-way relationships with Windows NT 4.0 domains. You can create two types of one-way trusts: an outbound trust on the local or specified domain, and an inbound trust on the specified target domain. Trustdom�s syntax is
C:\> trustdom [[domain[:dc],]target_domain[:dc]] [Options]
The default switch is -out. To see a list of other switches, use the /? switch.
