Configure The DNS Forwarders
Configure The DNS Forwarders :
1. Click Start, point to Programs, point to Administrative Tools, and then click
DNS to start the DNS Management Console.
2. Right click the DNS Server object for your server in the left pane of the console, and click
Properties.
3. Click the Forwarders tab.
4. Check the Enable forwarders check-box.
5. In the IP address box enter the IP address of the DNS servers you
want to forward queries to - typically the DNS server of your ISP.
You can also move them up or down. The one that is highest in the list gets
the first try, and if it does not respond within a given time limit - the query
will be forwarded to the next server in the list.
Create Invisible Folder in Windows

LDAPV3 and LDAPv2
Differences Between LDAPv2 and LDAPv3 :
LDAPv3 supports the following implementations that were not supported in LDAPv2:
•The use of UTF-8 for all text string attributes to support extended character sets. Active Directory sends all responses in UTF-8 encoded form.
•Operational attributes that the directory maintains for its own use (for example, to log the date and time when another attribute is modified).
•Referrals, which allow a server to direct a client to another server that might have the information the client is requesting. An LDAP server can return a referral to an LDAP client when the operation presented by the client cannot be serviced locally and the LDAP server has knowledge of other LDAP servers that can handle the operation.
•Schema publishing with the directory, which allows a client to discover what object classes and attributes a server supports.
•Extended searching operations that allow paging and sorting of results and client-defined searching and sorting controls.
•Stronger security through an SASL-based authentication mechanism.
•Extended operations, which provide additional functionality without changing the protocol version.
LDAPv3 is backward compatible with LDAPv2. A requirement of an LDAPv3 server is that an
LDAPv2 client be able to connect to it.

Definition of Sites & Services
Active Directory Sites and Services :
It is a group of one or more Tcp/ip subnets connected through
high speed links.
Types of sites and services :
1. Inter site Replication. [ Between the site replication is going to happen].
2. Intra Site Replication. [ Within the site replication is going to happen].

Win 2008 Date & Time Settings.
Configure Time and Date Settings in Windows 2008 Server Core :
1. On the server running a Server Core installation, type the following
command at a command prompt: Control timedate.cpl
This will fire up the Time and Date Control Panel applet
(one of two .CPL survivors on Server Core…)
2. In order to change the clock and date, press the Change Date and Time button
3. In order to change the time zone, press the Change Time Zone button.
4. When done, press Ok to close the applet.

GLOBAL CATALOG SERVER
To configure a Windows 2000/2003 Domain Controller as a GC server, perform the following steps:
1. Start the Microsoft Management Console (MMC) Active Directory Sites and
Services Manager. (From the Start menu, select Programs, Administrative Tools,
Active Directory Sites and Services Manager).
2. Select the Sites branch.
3. Select the site that owns the server, and expand the Servers branch.
4. Select the server you want to configure.
5. Right-click NTDS Settings, and select Properties
6. Select or clear the Global Catalog Server checkbox, which the Screen shows.
7. Click Apply, OK.
You must allow for the GC to replicate itself throughout the forest. This process might take anywhere between 10-15 minutes to even several days, all depending on your AD infrastructure.

Recovery Console Mode
Change the Recovery Console mode Password in Win 2000 Domain Controllers:
On Windows 2000, if you do know the Directory Service Restore Mode Administrator password you can easily change it to something else by using the following method:
1. Shut down the domain controller on which you want to change the password.
2. Restart the computer. When the selection menu screen is displayed
during the restart process, press F8 to view advanced startup options.
3. Select the Directory Service Restore Mode option.
4. After you successfully log on, use one of the following methods to change
the local Administrator password:
At a command prompt, type the following command:
net user administrator *
5. Shut down and restart the computer.
You can now use the Administrator account to log on to Recovery Console or Directory Services Restore Mode using the new password.
