Another  kill it with fire  approach is to just restart the MSSQLSERVER service  I like to do stuff from the commandline  Pasting this exactly into CMD will do it  NET STOP MSSQLSERVER  amp  NET START MSSQLSERVER  Or open  services msc  and find  SQL Server  MSSQLSERVER   and right-click  select  restart    This will  for sure  for sure  kill ALL connections to ALL databases running on that instance    I like this better than many approaches that change and change back the configuration on the server database

The option working for me in this scenario is as follows     Start the  Detach  operation on the database in question  This wil open a window  in SQL 2005  displaying the active connections that prevents actions on the DB   Kill the active connections  cancel the detach-operation   The database should now be available for restoring

I usually run into that error when I am trying to restore a database I usually just go to the top of the tree in Management Studio and right click and restart the database server  because it s on a development machine  this might not be ideal in production    This is close all database connections

I use sp who to get list of all process in database  This is better because you may want to review which process to kill   declare  proc table      SPID bigint      Status nvarchar 255       Login nvarchar 255       HostName nvarchar 255       BlkBy nvarchar 255       DBName nvarchar 255       Command nvarchar MAX       CPUTime bigint      DiskIO bigint      LastBatch nvarchar 255       ProgramName nvarchar 255       SPID2 bigint      REQUESTID bigint    insert into  proc exec sp who2  select     KillCommand   concat  kill    SPID       from     proc   Result You can use command in KillCommand column to kill the process you want to   SPID    KillCommand 26      kill 26  27      kill 27  28      kill 28

Using SQL Management Studio Express   In the Object Explorer tree drill down under Management to  Activity Monitor   if you cannot find it there then right click on the database server and select  Activity Monitor    Opening the Activity Monitor  you can view all process info  You should be able to find the locks for the database you re interested in and kill those locks  which will also kill the connection   You should be able to rename after that

The reason that the approach that Adam suggested won t work is that during the time that you are looping over the active connections new one can be established  and you ll miss those  You could instead use the following approach which does not have this drawback   -- set your current connection to use master otherwise you might get an error  use master ALTER DATABASE YourDatabase SET SINGLE USER WITH ROLLBACK IMMEDIATE   --do you stuff here   ALTER DATABASE YourDatabase SET MULTI USER

Take offline takes a while and sometimes I experience some problems with that    Most solid way in my opinion   Detach Right click DB -  Tasks -  Detach    check  Drop Connections   Ok  Reattach Right click Databases -  Attach   Add    -  select your database  and change the Attach As column to your desired database name  Ok
