How can I fix “Display driver igfx stopped responding and has recovered” errors?

Try this:
1. In Windows Vista, go Start Menu (blue circle in lower left) => Control Panel => Check for Updates (under Security) => Change Settings => put checkmarks next to “Include recommended updates…” and “Use Microsoft Update”. Single left-click on the OK button. This will return you to the original update window.
2. Choose “Check for updates…” from the left side of the window. If potential updates are found, single left-click on “View available updates”. Mark all updates for installation, using checkmarks, then single left-click on Install. Restart your computer after all updates have been installed.
If that fails, go to the Drivers and Downloads section of http://support.dell.com/ and then enter your computer’s Service Tag. This will allow you to download updates which have been designed specifically for your computer. Due to the nature of your problem, I recommend that you install BIOS and graphics updates. Restart your computer after installing each of these updates.

Enable Active Directory Recycle Bin

Step 1: Enable Active Directory Recycle Bin

Updated: February 28, 2011
Applies To: Windows Server 2008 R2

This step provides instructions for the following tasks:

• Raising the forest functional level
  
  
• Enabling Active Directory Recycle Bin
  
  

Raising the forest functional level

You can enable Active Directory Recycle Bin only if the forest functional level of your environment is set to Windows Server 2008 R2. You can raise the forest functional level by using the following methods:

• Set-ADForestMode Active Directory module cmdlet
  
  

  Note

  The Active Directory module for Windows PowerShell in Windows Server 2008 R2 is a Windows PowerShell™ module (named Active Directory) that consolidates a group of cmdlets. You can use these cmdlets to manage your Active Directory domains, Active Directory Lightweight Directory Services (AD LDS) configuration sets, and Active Directory Database Mounting Tool instances in a single, self-contained package. For more information, see What's New in AD DS: Active Directory Module for Windows PowerShell (http://go.microsoft.com/fwlink/?LinkID=140056).

  
  
• Ldp.exe
  
  

Membership in Enterprise Admins, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

To raise the forest functional level to Windows Server 2008 R2 using the Set-ADForestMode cmdlet

1. Click Start, click Administrative Tools, right-click Active Directory Module for Windows PowerShell, and then click Run as administrator.
   
2. At the Active Directory module for Windows PowerShell command prompt, type the following command, and then press ENTER:
   Set-ADForestMode [-Identity] [-ForestMode]
   To set the forest functional level to Windows Server 2008 R2, type Windows2008R2Forest for .
   For example, to set the forest functional level of contoso.com to Windows Server 2008 R2, type the following command, and then press ENTER:
   Set-ADForestMode –Identity contoso.com -ForestMode Windows2008R2Forest
   

For more information about the Set-ADForestMode cmdlet, at the Active Directory module for Windows PowerShell command prompt, type Get-Help Set-ADForestMode, and then press ENTER.

Note

You can use the Set-ADObject cmdlet to raise the functional level of an AD LDS configuration set. For example, to raise the functional level of an AD LDS configuration set on a local AD LDS server, where the distinguished name of the AD LDS configuration directory partition is CN=Configuration,CN={32E430E4-42D3-4663-BCA7-5F5DFDC898}, use the following cmdlet: Set-ADObject -Identity 'CN=Partitions,CN=Configuration,CN={32E430E4-42D3-4663-BCA7-5F5DFDC898}’ -Replace @{'msds-Behavior-Version'=4} -Server localhost:50000

To raise the forest functional level to Windows Server 2008 R2 using Ldp.exe

1. To open Ldp.exe, click Start, click Run, and then type ldp.exe.
   
2. To connect and bind to the server that hosts the forest root domain of your AD DS environment, under Connection, click Connect, and then click Bind.

4. In the console tree, double-click the distinguished name (also known as DN) of the configuration directory partition, and then navigate to the CN=Partitions container.
   
5. Right-click the CN=Partitions container’s distinguished name, and then click Modify.
   
6. In the Modify dialog box, in Edit Entry Attribute, type msDS-Behavior-Version.
   
7. In the Modify dialog box, in Values, type 4 (the value of the Windows Server 2008 R2 forest functional level).
   
8. In the Modify dialog box, under Operation click Replace, click Enter, and then click Run.
   

Enabling Active Directory Recycle Bin

After the forest functional level of your environment is set to Windows Server 2008 R2, you can enable Active Directory Recycle Bin by using the following methods:

• Enable-ADOptionalFeature Active Directory module cmdlet (This is the recommended method.)
  
• Ldp.exe
  
  

Note
In this release of Windows Server 2008 R2, the process of enabling Active Directory Recycle Bin is irreversible. After you enable Active Directory Recycle Bin in your environment, it cannot be disabled.

Membership in Enterprise Admins, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

To enable Active Directory Recycle Bin using the Enable-ADOptionalFeature cmdlet

1. Click Start, click Administrative Tools, right-click Active Directory Module for Windows PowerShell, and then click Run as administrator.
   

   Warning
   If you do not use the Active Directory Module for Windows PowerShell to run the following commands, you will see errors.

2. At the Active Directory module for Windows PowerShell command prompt, type the following command, and then press ENTER:
   Enable-ADOptionalFeature -Identity -Scope -Target
   

   Note
   The distinguished name (also known as DN) of Active Directory Recycle Bin is CN=Recycle Bin Feature,CN=Optional Features,CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=,DC=, where and represent the appropriate forest root domain name of your Active Directory Domain Services (AD DS) environment.

   
   
   For example, to enable Active Directory Recycle Bin for contoso.com, type the following command, and then press ENTER:
   Enable-ADOptionalFeature –Identity ‘CN=Recycle Bin Feature,CN=Optional Features,CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=contoso,DC=com’ –Scope ForestOrConfigurationSet –Target ‘contoso.com’
   

Note

You can also use the Enable-ADOptionalFeature cmdlet to enable Active Directory Recycle Bin in an AD LDS environment. For example, to enable Active Directory Recycle Bin on a local AD LDS server, where the distinguished name of the AD LDS configuration directory partition is CN=Configuration,CN={372A5A3F-6ABE-4AFD-82DE-4A84D2A10E81}, use the following cmdlet: Enable-ADOptionalFeature 'recycle bin feature' -Scope ForestOrConfigurationSet -Server localhost:50000 -Target 'CN=Configuration,CN={372A5A3F-6ABE-4AFD-82DE-4A84D2A10E81}'

How to configure Duplicate Backup Jobs in Backup Exec for Windows Servers (BEWS)

Problem

How to configure Duplicate Backup Jobs in Backup Exec for Windows Servers (BEWS)

Solution

It is possible to create a job to duplicate backup data with the option to either duplicate existing backup sets or to duplicate backup sets immediately following a scheduled job.

When duplicating existing backup sets, the backup sets selected from catalogs are read from the source media and written to the selected destination, such as a drive, drive pool, or backup folder. It is possible to schedule when this type of job runs.

When selecting to duplicate backup sets following a job, a backup job will run, and then the backup sets it created are copied to the destination targeted for the duplicate job. To duplicate backup sets following a job, the backup job must be scheduled to run and must not be associated with any other duplicate jobs. It is not possible to  schedule this job; instead, the duplicate job runs only after the related or linked backup job completes.


To duplicate backup data:

1.  From the navigation bar, click Job Setup
2.  Under Backup Tasks, select New job to duplicate backup data (Figure 1)

Figure 1
 

2a.     To copy existing backup sets to another destination:
        Select Duplicate existing backup sets, and then click OK (Figure 2).
        Select the backup sets to be copied.

Figure 2    
 

2b.     To duplicate backup sets created when a scheduled backup job runs:
        Select Duplicate backup sets following a job (Figure 3), and then click OK.
        Select the scheduled backup job to be used as the source.

Figure 3
 
3.  On the Properties pane, under Destination, select Device and Media, and complete these options as described in Device and Media Options for Backup Jobs and Templates
4.  On the Properties pane, under Settings, click General, and complete these options as described in General Options for a Duplicate Job
5.  On the Properties pane, under Settings, click Advanced, and complete these options as described in Advanced Options for a Duplicate Job
6.  If Backup Exec is required to send a notification when the backup job completes, on the Properties pane, under Settings, click Notification
7.  If duplicating data from a scheduled backup job, click Run Now

The duplicate job will launch immediately following the completion of the scheduled backup job.

If duplicating data from an existing backup set, either click Run Now or under Frequency click Schedule to set the scheduling options to be used.

Outlook 2007: Recall or replace a message after it is sent

Recall and replace a message

You send an e-mail message, asking your co-workers to review the sales figures for this year, but you forget to attach the sales figures. After you send the message, your Inbox is flooded with messages that ask "What attachment?", "I didn't get the attachment!", or "Can you resend the attachment?"
How can you undo your error? You can recall the original message and then resend it with the missing attachment. For all of your co-workers who haven't opened the message yet, you can perform an e-mail sleight of hand and replace the original message with another one that contains the attachment.

Recall and replace a message

Do the following:

1. In Mail, in the Navigation Pane, click Sent Items.
2. Open the message that you want to recall and replace.
3. On the Message tab, in the Actions group, click Other Actions, and then click Recall This Message.

I don't see the Recall This Message command

4. Click Delete unread copies and replace with a new message.

 Note   If you are sending the message to a large number of people, you may want to clear the Tell me if recall succeeds or fails for each recipient check box.

5. Click OK, and then type a new message and include the attachment.
6. Click Send.

In another scenario, you accidentally send a message announcing a party for your staff that afternoon. However, the party is actually scheduled for the next week. In this case, you want to recall the message but not replace the message at this time.

Recall a message

Do the following:

1. In Mail, in the Navigation Pane, click Sent Items.
2. Open the message that you want to recall.
3. On the Message tab, in the Actions group, click Other Actions, and then click Recall This Message.

Will my recall be successful?

The success or failure of a recall depends on the recipients' settings in Microsoft Outlook. The following four scenarios explain what happens in various situations, and an additional scenario describes the recall of a message sent to a Microsoft Exchange public folder.

Action	Result
You send an e-mail message to someone. You recall the original message and replace it with a new one. On the recipient's computer, under Tracking Options, the Process requests and responses on arrival check box is selected. (To view this setting, on the Tools menu, click Options, click E-mail Options, and then click Tracking Options.)	Both the original message and the recall message are received in the recipient's Inbox. Assuming the original message has not been read, the original message is deleted and the recipient is informed that you, the sender, deleted the message from his or her mailbox.  Note   If the original message is marked as read (viewing in the Reading Pane is not reading in this scenario) when the recall message is processed, the recipient is informed that you, the sender, want to delete the message, but the message remains in the recipient's Outlook folder.
You send an e-mail message to someone. You recall the original message and replace it with a new one. On the recipient's computer, under Tracking Options, the Process requests and responses on arrival check box is not selected. (To view this setting, on the Tools menu, click Options, click E-mail Options, and then click Tracking Options.)	Both the original message and the recall message are received in the recipient's Inbox. On the recipient's computer, one of the following occurs: If the recipient opens the recall message first, the original message is deleted, and the recipient is informed that you, the sender, have deleted the message from their mailbox. If the recipient opens the original message first, the recall fails, and both the original and recall messages are available.  Note   If the original message is marked as read (viewing in the Reading Pane is not reading in this scenario) when the recall message is processed, the recipient is informed that you, the sender, want to delete the message, but the message remains in the recipient's Outlook folder.
You send an e-mail message to someone. You recall the original message and replace it with a new one. On the recipient's computer, either by rule or by action of the recipient, the original message is moved to another folder and the recall message remains in the Inbox (or it is moved to another folder as well).	As long as the recall message and the original message exist in separate folders, the recipient receives a message indicating that a recall attempt failed. This occurs regardless of the Outlook configurations and the read status of the message. The original message and the new message are both available to the recipient.  Note   If the recipient read the original message and then marks it as unread, Outlook treats it as if it had never been read and recalls it successfully.
You send an e-mail message to someone. You recall the original message and replace it with a new one. On the recipient's computer, either by rule or by action of the recipient, both messages are moved to the same folder. This results in behavior similar to that which occurs when Outlook is not configured to automatically process messages.	On the recipient's computer, one of the following occurs: If the recipient opens the recall message first, the original message is deleted, and the recipient is informed that you, the sender, deleted the message from his or her mailbox. If the recipient opens the original message first, the recall fails, and both the old and new messages are available.  Note   If the recipient read the original message and then marked it as unread, Outlook treats it as if it had never been read and recalls it successfully.
You send an e-mail message to a public folder. You recall the original message and replace it with a new one.	One of the following occurs: If the recipient who reads the recall message has read access to all the items in the public folder but did not read the original message, the recall succeeds, and only the new message remains. You, the sender, receive a message indicating that the recall succeeded. If the recipient has already marked the original message as read, he or she is informed that the recall failed, and only the recall message is deleted. If a user with any other public folder rights opens the recall message, the recall fails, and the user receives a message indicating that the recall failed. Both the old and new messages remain in the public folder.  Notes  If the recipient reads the original message and then marks it as unread, Outlook treats it as if it had never been read and recalls it successfully. In the public folder, it is the reader's rights, not the sender's, that determine the success or failure of the recall.
