Windows 2000 Active Directory is designed to be a scaleable network structure. The Active Directory is a scalable, distributed database that contains information about an organization's network resources. This database is maintained by multiple Domain Controllers throughout the network by using a process known as Active Directory Replication. Replication is the process by which changes to the Active Directory database are transferred between domain controllers.

    The Schema partition, Configuration partition, and Global Catalog can be
    replicated using either RPC or SMTP. The Domain parition can only be
    replicated using RPC.
    
    If the promotion of a domain controller fails, look in the folder:
    	%SYSTEMROOT%\debug\
    for the following files: dcpromo.log and dcpromoui.log
    
    Unattended setup requires the use of the dcpromo command with the
    /answer: switch.
    c:\>net local group "Pre-Windows 2000 Compatible Access" Everyone/delete
    
    Active Directory database: %SYSTEMROOT%\NTDS\NTDS.DIT
    dcpromo errors/log files:  %SYSTEMROOT%\debug\dcpromo.log,dcpromoui.log
    
    Show failed domain controllers: repadmin.exe /unreplicated
    
    All domain controllers replicate with each other in intrasite replication,
    only bridgehead servers participates in intersite replication.
    
    For a small network, 512kb is the lowest speed for combining subnets or
    sites.
    
    The "site link schedule" is the adjustment area for replication interval or
    "triggering".
    
    On domain controller installation, the "Windows 2000-only permission" is not
    the default. The default allows anonymous access for NT4 and 9x computers.
    To prevent anonymous access and optimize security:
    net local group "Pre-Windows 2000 Compatible Access" Everyone/delete
    or check "Windows 2000-only permission" during dcpromo.
    
    Microsoft Recommends:
    	Don't link existing GPOs to sites. Control site GPOs from site/props/
    	GP tab. Sites can contain more than one domain (security/owner?).
    
    LDAP://CN=Admins,CN=ITDept,dc=spcsys,dn=com
    
    PXE Boot:
    	Adapter/RIS disk initialize
    	DHCP
    	F12 - Initiates a network service boot
    
    Roaming profiles:
    	redirect "Application data" and "My Documents"
    	no offline folders. roaming profiles and offline folders both sync!
    
    The KCC creates only inbound connections.
    
    If you manually create a preferred bridgehead server and it fails, the KCC
    CANNOT select an alternate.
    
    You can use AD zones with BIND if you delegate zones:
    	_tcp.spcsys.com
    	_udp.spcsys.com
    	_msdcs.spcsys.com
    	_sites.spcsys.com
    to an Windows 2000 DNS and manually create the zones.
    
    If you want to have Secure DDNS updates and also use non-Windows 2000 client
    computers, you must have the DHCP server update the DDNS server for the
    client. The DHCP server will be a member of the "DNS Update Proxy" group
    which strips its security, therefore, don't have the DHCP server on a
    domain controller; for security purposes.

    The search feature in Windows 2000 does not include shared folders.
    Make a shortcut to published folders on users desktop?
    	"My Network Places/Entire Network/Entire Contents/Directory/domain/"
    
    The Global Catalog begins: "My Network Places/Entire Network/"
    
    implicit deny = not given access
    explicit deny = denying specifically
    
    No SMTP replication between domain controllers in seperate sites if they are
    in the same domain because the entire domain content is replicated (not just
    the Global Catalog section). This is probably because the type of data that
    must be transferred (binary?).
    
    A site-link can connect more >2 sites for replication.
    
    A Distinguished Name or DN is:
    	dn="cn=jill jones,cn=Users,dc=spcsys,dc=com"
    
    Write permissions on OU = change attributes
    Create all child objects in OU = Create all...
    
    If you move a domain controller to a new site, you must make changes to the
    "NTDS Settings" object. The KCC does not detect physical location changes.
    It would replicate over site links (WAN) as intrasite replication.
