How to use Blackberry 7100 as a modem

For those who don’t know, here are the steps:

1. Connect your BlackBerry 7100 (BB 7100) with computer through USB cable.
2. Activate the Blackberry Handheld Manager and or Blackberry Device Manager (Depends on the Blackberry software version) and make sure the status is connected to the device.
3. Open Device Manager. Expand Modems and double click on Standard Modem.
4. Go to advance tab, add extra initialization command +cgdcont=1,”IP”,”your_apn_name” (depends on your network provider).
For example I put; cgdcont=1,”IP”,”satelindogprs.com” for Indosat Network. Sometime you may have to put a different format such us; +cgdcont=1,”IP”,”satelindogprs.com”,””,0,0
5. After that, do a test query on your modem. You should see what type of modem, Research In Motion, etc.
6. Create a new Internet Connection. On number to dial type in *99#. Leave the password and username blank.
7. Last, depends on the Network Provider, you may have to enter the DNS server IP on TCP/IP Property. In my experience, most of the time leaving the DNS setting to be automatic should be fine. Confirm with your Network Provider about the IP or if you find any difficulty connecting to the Internet.
8. Dial the newly created connection and have fun trying.

How to configure a display message when users log on to the Windows 2003 domain

You can configure Windows Server to display a message to users when they log on. The message appears after the user presses CTRL+ALT+DEL and disappears after the user clicks OK. After the message disappears, the user can complete the logon process.

Configuring a Group Policy Setting for a Domain:
1. On the domain controller, start the Group Policy Management snap-in.
2. Expand the forest object in the left pane.
3. Expand the domains object in the left pane. Expand yourdomain.
4. Right Click Default Domain Policy, and then click Edit.
5. Expand the following folder:
Computer Configuration\Windows Settings \Security Settings\Local Policies\Security Options
6. In the right pane, double-click Policies, and then follow these steps to create the message text:

> On a Windows Server 2003-based domain controller:
a. Click Interactive logon: Message title for users attempting to log on, and then type the text that you want to appear in the title bar of the message dialog box.
b. Click Interactive logon: Message text for users attempting to log on, and then type the text of the message that you want to appear in the message dialog box.
> On a Windows 2000-based domain controller:
a. Click Message title for users attempting to log on, and then type the text that you want to appear in the title bar of the message dialog box.
b. Click Message text for users attempting to log on, and then type the text of the message that you want to appear in the message dialog box


Note: If you do not use carriage returns in your display message, the maximum number of characters that you can add to the logon box is 512. If you add carriage returns, you can add up to 2048 characters (512 characters per line).

How to audit Active Directory account management in Windows 2003?

The following was taken from one of conversation on Microsoft Managed Newsgroup.

By default, Windows Server 2003 system ships the following Audit policies:
> Audit account logon event
> Audit account management
> Audit directory service access
> Audit logon events
> Audit object access
> Audit policy change
> Audit privilege use
> Audit process tracking
> Audit system events

To audit add/deleting events, you may open Default Domain Controller Policy, locate Computer Configuration\Windows Settings\Security Settings\Local Policies\Audit Policy, enable "Audit account management" with Success.

After that, when a new user is created on a domain controller, the following event will be logged:

Event ID: 624
Type: Success Audit
Description: User Account Created:
New Account Name: %1 New Domain: %2
New Account ID: %3 Caller User Name: %4
Caller Domain: %5 Caller Logon ID: %6
Privileges %7

When an existing user is deleted on the domain controller, the following event will be logged:
Event ID: 630
Type: Success Audit
Description: User Account Deleted:
Target Account Name: %1 Target Domain: %2
Target Account ID: %3 Caller User Name: %4
Caller Domain: %5 Caller Logon ID: %6
Privileges %7

We can monitor event 633 and 632 which records security enabled global group membership removed/added.

E.g. you, domain\administrator1 have removed/added user1 from/to group1.
And the following events will be recorded.

Event ID: 633 (logged when you remove a user from a security group)
Type: Success Audit
Description: Security Enabled Global Group Member Removed:
Member Name: CN=user1,CN=Users,DC=domain,DC=com.
Member ID: domain\user1
Target Account Name: domain\administrator
Target Domain: Domain
Target Account ID: domain\group1
Caller User Name: administrator1
Caller Domain: domain

Event ID: 632 (logged when you add a user from a security group)
Type: Success Audit
Description: Security Enabled Global Group Member Added:
Member Name: CN=user1,CN=Users,DC=domain,DC=com.
Member ID: domain\user1
Target Account Name: domain\administrator
Target Domain: Domain
Target Account ID: domain\group1
Caller User Name: administrator1
Caller Domain: domain

We can audit who at what time, modifies which attribute of the user. But we cannot see what's the
Workstation or what's the application. To audit the property change issues, follow the below steps:

1. Enable the Auditing for Directory Services Access for Success in the Default Domain Controller Policy.
2. Go to the Security of the User account you want to audit and Enabled the Auditing for WRITE ATTRIBUTES for Everyone.

We will get the 566 event when any one will change any Attribute like

Event Type: Success Audit
Event Source: Security
Event Category: Directory Service Access
Event ID: 566
Date: 07/06/2007
Time: 11:14:56
User: ALPINESKIHOUSE\t1
Computer: ASH-DC1
Description:
Object Operation:
Object Server: DS
Operation Type: Object Access
Object Type: user
Object Name: CN=t6,CN=Users,DC=alpineskihouse,DC=com
Handle ID: -
Primary User Name: ASH-DC1$
Primary Domain: ALPINESKIHOUSE
Primary Logon ID: (0x0,0x3E7)
Client User Name: t1
Client Domain: ALPINESKIHOUSE
Client Logon ID: (0x0,0x67A9AEE)
Accesses: Write Property

Properties:
Write Property
Public Information
Department
user

Additional Info:
Additional Info2:
Access Mask: 0x20

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.

3. Now to check on which DC the change was initiated you can take the
Repadmin report as Follow
Repadmin /showmeta "DN OF THE USER" and you can see the Originating DC and the timestamp.
