How to remove Windows NT4 BDC From Active directory

From this Microsoft article we read:
After upgrading the NT4 domain to Windows 2000/2003 Domain, you may find out that the old BDC (Backup Domain Controller) computer account still exits in the Active Directory.We have the following options to remove the old BDC from the Active Directory:
- Option A: Upgrade the current BDC server to Windows 2000/2003.
- Option B: Remove the computer account from the Active Directory from the BDC.
  1. Log on into the BDC with an account that is a member in "Domain Admins" users group.
  2. Go to "Start" -> "Run" -> Write "srvmgr" and press on "Enter" button.
  3. Remove the BDC computer account from the domain.
- Option C: Remove the computer account from the Active Directory manually.
   1. Logon into a Windows XP workstation or into the domain controller with an account that is a member of "Domain Admins" users group.
   2. Install Windows Support tools.
   3. Go to "Start" -> "Run" -> Write "adsiedit.msc" and press on "Enter" button.
   4. If your FQDN domain name is: domain.local and the BDC remains in "Domain Controller" you can use the following instructions:
a. Expand Domain NC, expand DC=Domain,DC=Local, and then expand OU=Domain Controllers.
b. Right-click the computer name BDC, and then right click and choose "Delete"..
Note: Removing the computer account will prevent the BDC functions and will drop the option to use network resources from the domain.

From this link we read:
# Log in to Windows as the user whose shell you want to change.

# Select Edit --> New --> String Value and give the new value the name Shell
# With the new value selected, select Edit --> Modify.
# Set the value data to the path of the new shell— for example
C:\Program Files\VMware\VMware VDM\client\bin\wswc.exe
Note: No quotations.
# Click OK, and then exit Registry Editor, log out of the user’s account, and log back in.
# Apply it to a group of computers via a GPO to their computer account.
# Turn on auto logon using this article from Microsoft KB.

Forcing adsl Modulation on Thomson 585v7

from this link we read:

for adsl
xdsl debug multimode config=g992.1_annex_a

or, the following for adsl2
xdsl debug multimode config=g992.3_annex_a

or, for adsl2+
xdsl debug multimode config=g992.5_annex_a

Once the disclaimer message shows your router will resync; finish off by typing
which saves the settings, use exit to shut the telnet session down

To switch back to multi mode use the following in place of the single mode command (typed on a single line).
Don't forget to saveall afterwards.
xdsl debug multimode config=t1.413issue2+g992.1_annex_a+g992.3_annex_a+g992.3_annex_m+g992.5_annex_a+g992.5_annex_m

How To Perform Scheduled Backups For SQL Server 2005 Express In Windows 7

from we read:

The steps to perform scheduling backups for SQL Server 2005 Express in Windows 7:

1. Create a store procedure that allows generate the dynamic backup file name, with types of backup to run such as full, differential or transaction log backups and location of the backup files:

USE [master]

CREATE PROCEDURE [dbo].[sp_BackupDatabase]
@databaseName sysname, @backupType CHAR(1)

DECLARE @sqlCommand NVARCHAR(1000)


IF @backupType = ‘F’
SET @sqlCommand = ‘BACKUP DATABASE ‘ + @databaseName +
‘ TO DISK = ”C:\Backup\’ + @databaseName + ‘_Full_’ + @dateTime + ‘.BAK”’

IF @backupType = ‘D’
SET @sqlCommand = ‘BACKUP DATABASE ‘ + @databaseName +
‘ TO DISK = ”C:\Backup\’ + @databaseName + ‘_Diff_’ + @dateTime + ‘.BAK”

IF @backupType = ‘L’
SET @sqlCommand = ‘BACKUP LOG ‘ + @databaseName +
‘ TO DISK = ”C:\Backup\’ + @databaseName + ‘_Log_’ + @dateTime + ‘.TRN”’

EXECUTE sp_executesql @sqlCommand

2. Create a SQL script to run the backup. In this example, we will backup database master and saved the below SQL script as dbbackup.sql and save in “c:\Backup” folder.

sp_BackupDatabase ‘master’, ‘F’

3. Create a scheduled task in Windows 7 which can be found in Control Panel -> System and Security -> Administrative Tools -> Schedule Tasks.

Click on “Create a Basic Task” and “Create Basic Task” wizard will be displayed. Type in “SQL Express Data Backup” in the “Name” and click “Next” button.

4. Specify when you want the task to be start (Daily), then click “Next” button.

5. Specify what time you want the task to be start, then click “Next” button.

6. Click Start a program to perform the task, then click “Next” button.

7. Click on Browse button to select SQLCMD.exe file from “C:\Program Files\Microsoft SQL Server\90\Tools\Binn” and type the following command in “Add arguments (optional)”: -S serverName -E -i C:\Backup\dbBackup.sql

The meaning of the command:

-S (this specifies the server\instance name for SQL Server)
serverName (this is the server\instance name for SQL Server)
-E (this allows you to make a trusted connection)
-i (this specifies the input command file)

8. Click on “Next” button to finish creating task.

If you want to test the task which has been created then you can go back to the Task Scheduler, right click on the task and select "Run".
