Password Policy How to use it on Domain Controller

Password Policy

Go to Start – Program – Administrative Tools – Domain Controller Security Policy – Open A/c Policy – Open

password policy: You will find Six Password Policies

1. Minimum Password length: This security setting determines the least number of characters that a

password for a user account may contain. You can set a value of between 1 and 14 characters, or you

can establish that no password is required by setting the number of characters to 0.

Default: 7 on Domain Controller

0 on stand-alone Server

2. Password must meet complexity requirement: If this policy is enabled, passwords must meet the

following minimum requirements when they are changed or created:

1 Password should not contain significant portions of the user's account name or full name

2 Password should be at least six characters in length

3 Password should Contain characters from three of the following four categories:

a) English uppercase characters (A through Z)

b) English lowercase characters (a through z)

c) Base 10 digits (0 through 9)

d) Non-alphabetic characters (for example, !, $, #, %)

Default: Enabled on domain controllers.

Disabled on stand-alone servers.

3. Minimum Password Age: This security setting determines the period of time (in days) that a

password must be used before the user can change it. You can set a value between 1 and 998 days,

or you can allow changes immediately by setting the number of days to 0.

Default: 1 on Domain Controller

0 on stand-alone Server

[Note: Configure the minimum password age to be more than 0 if you want “Enforce password history” to be effective]

4. Maximum Password Age: This security setting determines the period of time (in days) that a

password can be used before the system requires the user to change it. You can set passwords to

expire after a number of days between 1 and 999, or you can specify that passwords never expire by

setting the number of days to 0. If the maximum password age is between 1 and 999 days, the

Minimum password age must be less than the maximum password age. If the maximum password

age is set to 0, the minimum password age can be any value between 0 and 998 days.

Default: 42 days

Offline Files on Server 2003/XP/Windows7

Offline Files

If your network connection is not stable or network connection is not available at the time then you can make

network files available offline by storing shared files or folder on your computer so that they are accessible

when you are not connected to the network. If you do this, you can work with the files in the same way as you

work with them when you are connected to the network. When you reconnect to the network, changes that

you made to the files are updated to the network.

To Making Files & Folder Available Offline.

On Server

Go to Share Folder – Properties – Sharing – Offline Setting – Enable – Apply – Ok

Configure Client Computer to Use Offline File.

On Client Computer or Win XP /Win7

Go to – My Computer – Tools – Folder Option – Offline Files – Enable – Apply – Ok

Or

Go to – Control Panel – Folder Option – Offline Files – Enable – Apply – Ok

Creating Home Folder and Assign Home Folder to a User

Home Folder

Home folder makes it easier for an administrator to backup users file & manages user’s a/c by collecting the

users file in one location. If you assign a home folder to a user you can store user’s data in a central location

on a server, make backup & recovery of data easier & more reliable.

One more advantage of home folder is that wherever user would login, user would be able to access his Home

folder (his saved files…etc) which is assigned by Sever Administrator.

To Assign Home folder

First of all make a share folder then

Go to Start – Run – dams – Users – Click on User – Properties – Profile – Connect – Select Drive letter – In To

box type [\\IP or name of Server\folder share name] – Apply – Ok

Creating User Profiles Step By Step

User Profiles

User profile is used to save user’s settings & preferences & to provide a user with a default location or folder

to save documents & personal files. Profile can be at local computer or network location both. User profile can

also be changed by the user or locked by the administrator. Profiles can be redirected to a network share and

accessed by the user from any computer in the network.

There are three type of User Profile:

1. Local User Profile 

2. Roaming User profile 

3. Mandatory User Profile

Local user Profile is located in the in the “Documents & Settings” folder on the Local Computer. When a user

logs on to the local computer for the 1st time, a subfolder matching to their username is created under the

“Documents & Settings” folder which is located in Window’s drive (C drive). In this subfolder the users profile

& a hidden system file (netuser.dat) is also created.

When a user logs on to the computer, the ntuser.dat file is loaded, this contains the user’s preferences &

settings. Any changes to the user setting or preferences are saved back to the ntuser.dat file when the user

logs off the computer.

Roaming User Profile can be created when a users access more than one PC or move around the network to

ensure that the user will receive his or her user settings & preferences, no matter where they log on. This user

profile is created by the administrator in Active Directory by using profile tab in the user’s properties.

When a user logs on using Roaming Profile a local profile will remain on the local machine also if there is

unavailability of network then next time the user logs on from that PC, the locally cached profile will be

loaded. Changes to the local profile will not saved back to the Roaming profile

Note: when a user logs on user’s profile are taken form the network which creates a network traffic & long

logon time if user saves large files to their desktop or to their My Documents folder.

Steps to Create Roaming User Profile:

1. Create a share folder in any drive in any PC.

2. Open Active directory users & computers

3. Select user to create roaming profile & Go to its Properties

4. In User Properties click on profile tab.

5. Type Profile Path [\\IP of the share folder PC\Folder share name\%Username%]

Mandatory User Profile is used when administrator wants no changes to Users’ Settings & Preferences by any

user. This is a fixed profile of a user which can not be modified or changed, if still user makes changes to

his/her profile the all changes will be lost when the user logs off, the next time when user logs in again all

settings will be reset to mandatory user profile.

To make Mandatory user profile

Go to user profile – Right click on “ntuser.dat” file – Rename the file to ntuser.man

Note: The ntuser.dat file is a hidden system file by default. To see this go to folder option – view - uncheck “hide protected

operating system files”
