Recently I had issue which occured without any particular reason on SQL Server 2012. All of the sudden I start getting error message:

Cannot connect to WMI provider. You do not have permission or the server is
unreachable.
Note that you can only manage SQL Server 2005 servers with SQL
Server Configuration Manager.
Invalid Namespace.

when tried to run SQL Server Configuration Tools.

What resolved situation is command:

mofcomp C:\Program Files\Microsoft SQL Server\100\Shared\sqlmgmproviderxpsp2up.mof

Some of applications require additional SQL Server 2008 or 2012 fetures installed. Some of these features might not be available in standard setup of SQL Server. In that case you have to refer to Microsoft Dowloads web page in order to download additional components required for installation:

• Microsoft SQL Server 2012 SP1 Feature Pack
• Microsoft SQL Server 2012 Feature Pack
• Microsoft SQL Server 2008 R2 SP2 Feature Pack
• Microsoft SQL Server 2008 R2 Feature Pack

Unfortunately there is a problem when you try to add .Net Framework 3.51 to Windows Server 2012 using Server Manager. In order to fix that issue and get .Net Framework 3.51 installed (which is required by majority of applications and servers) issue following command from Command Prompt:

dism /online /enable-feature /all /featurename:NetFX3 /source:x:\sources\sxs

In order to assign static IPv4 address to Windows Server 2012 Core using power shell use:

New-NetIPAddress -IPAddress 172.16.48.11 -InterfaceAlias "Ethernet" -DefaultGateway 172.16.48.5 -AddressFamily IPv4 -PrefixLength 24

Just released small app for Android platform. This app allows to decrypt type 7 password from Cisco devices as well as passwords from Cisco VPN profiles (PCF files).

Password which can be recovered using this app:

• wireless keys fro Cisco access points,
• RADIUS/TACACS shared secrets
• NTP authentication keys
• Enable passwords (NOT enable secrets, which are stored using MD5)
• enc_GroupPwd – VPN group password from PCF file
• enc_UserPassword – VPN user password from PCF file

You can find app in Google Play:

When browsing repository of all scripts I did use in past, I found one which might be interesting. What this script does is:

• Backups database to disk (name of database stored in @dbname, patch for backup stored in @archive_path, name of backup fine stored in @fname)
• Compresses database backup using WinRAR (full command where to find WinRAR and how ot use it stored in @archive_cmd)
• Generates set of commands for FTP client (series of xp_cmdshell commands redirecting output to F:\Backup\ftpcmds)
• Uploads compressed backup to FTP server using command prompt FTP client command

I had that as small procedure executed automatically with SQL Server Agent. Script is for Microsoft SQL Server and I was running it on SQL Server 2000 and 2005. Here is code for that small procedure:

DECLARE @fname varchar(255)
DECLARE @fname_backup varchar(255)
DECLARE @fname_archive varchar(255)
DECLARE @archive_path varchar(255)
DECLARE @dbname varchar(255)
DECLARE @archive_cmd varchar(255)
DECLARE @put_cmd varchar(255)

SET @dbname = 'dbApplication'
SET @fname = @dbname + '_' + LTRIM(STR(DAY(GETDATE())))  + '.' + LTRIM(STR(MONTH(GETDATE()))) + '.' + LTRIM(STR(YEAR(GETDATE())))
SET @archive_path = 'F:\Backup\'
SET @fname_backup = @archive_path + @fname + '.BAK'
SET @fname_archive = @archive_path + @fname + '.RAR'
SET @archive_cmd = '"C:\Program Files\WinRAR\WinRAR.EXE" a ' + @fname_archive + ' ' + @fname_backup
SET @put_cmd = 'echo put ' + @fname_archive + '>> F:\Backup\ftpcmds'

PRINT @fname_backup
PRINT @fname_archive

BACKUP DATABASE @dbname TO DISK = @fname_backup WITH INIT

EXEC xp_cmdshell @archive_cmd
EXEC xp_cmdshell 'echo open 192.168.10.101> F:\Backup\ftpcmds'
EXEC xp_cmdshell 'echo user dbupload>> F:\Backup\ftpcmds'
EXEC xp_cmdshell 'echo password123>> F:\Backup\ftpcmds'
EXEC xp_cmdshell 'echo cd DB_Backup>> F:\Backup\ftpcmds'
EXEC xp_cmdshell 'echo bin>> F:\Backup\ftpcmds'
EXEC xp_cmdshell 'echo ha>> F:\Backup\ftpcmds'
EXEC xp_cmdshell @put_cmd
EXEC xp_cmdshell 'echo bye>> F:\Backup\ftpcmds'
EXEC xp_cmdshell 'ftp -d -i -n -s:F:\BACKUP\ftpcmds'

I hope that will be handy for someone to automate databsae backups and transfers.
