<strong>64</strong> <strong>bit</strong> <strong>Editions</strong> <strong>of</strong> <strong>Windows</strong> <strong>and</strong> Active Directory �<br />

- Active Directory content is successfully replicated among domain controllers in<br />

the <strong>64</strong> <strong>bit</strong> domain, including both Itanium-based servers <strong>and</strong> a 32 <strong>bit</strong><br />

Pentium III-based server.<br />

- Users are able to use Active Directory services transparently <strong>and</strong> easily from<br />

their 32 <strong>bit</strong> <strong>Windows</strong> 2000 clients, regardless <strong>of</strong> the platform architecture that<br />

provided the service.<br />

- Security credentials can be migrated from the production 32 <strong>bit</strong> Active<br />

Directory to an Itanium- based processor domain controller. It is not<br />

necessary to change the security access control lists on any <strong>of</strong> the migrated<br />

users’ files, shares, or applications.<br />

Flexibility <strong>of</strong> Active Directory Security<br />

The flexibility <strong>of</strong> security in Active Directory permits the execution <strong>of</strong> a <strong>64</strong> <strong>bit</strong> domain in an<br />

isolated forest while maintaining each user’s access to all resources on the production<br />

network.<br />

- From their user accounts <strong>and</strong> client machines in the <strong>64</strong> <strong>bit</strong> domain, participants<br />

have complete <strong>and</strong> unrestricted access to all <strong>of</strong> their resources in the downlevel<br />

<strong>Windows</strong> NT 4.0 <strong>and</strong> <strong>Windows</strong> 2000 domain infrastructures.<br />

- There are no problems with Trust relationships, SID migration, security access<br />

control lists, or sharing resources.<br />

32 <strong>bit</strong> Tools Ported to <strong>64</strong> <strong>bit</strong><br />

If a company has internally developed migration tools to work with their 32 <strong>bit</strong> <strong>Windows</strong> 2000<br />

infrastructure <strong>and</strong> requires that they work with <strong>Windows</strong> Advanced Server, Limited Edition,<br />

the internally developed user migration tool can be quickly <strong>and</strong> easily ported to the Itanium<br />

processor architecture.<br />
