  Hey,

  I am not sure if this is what you were looking for... but I can run this query to see the current server and all the linked servers on this instance of the server.

  select * from sys.sysservers

  Regards,

  Prakash.P

  I use this.

  Select Case

  When SERVERPROPERTY ('InstanceName') Is Null Then @@SERVERNAME

  Else SERVERPROPERTY ('InstanceName')

  End

  Have a look at what Books online has to say about @@servername and serverproperty(). My recommendation is to use consistently only select convert(nvarchar(128), serverproperty('servername')); Mixing the various alternatives for getting your server's name is a sure way to run into problems.

  To get the "instance" name you can also do:

  select @@ServiceName

  @@ServiceName would be ok if there are named instances.

  If none is available then select @@servicename results MSSQLSERVER.

  So if you are interested in only the instance name, without the servername,

  and replace instance name with servername, if there is no named instance then you could script:

  HAVE FUN WITH IT.

  declare @nameServer varchar(100)

  declare @nameMachine varchar(50)

  declare @kInstance varchar(50)

  declare @constrServer varchar(100)

  select @nameServer = convert(nvarchar(128), serverproperty('servername'));

  select @nameMachine = convert(nvarchar(128), serverproperty('machinename'));

  if len(@nameServer) = len(@nameMachine)

  select @kInstance = '' -- 'NN'

  else

  select @kInstance = right(@nameServer, len(@nameServer) - (len(@nameMachine)+1));

  -- construct name of server again from 2 variables:

  if @kInstance='' select @constrServer = @nameMachine

  else select @constrServer = @nameMachine + '\' + @kInstance;

  select @nameServer as Sname, @nameMachine as Mname, @kInstance as kInst, @constrServer as cServ

  -- if you are connected to a no named instance,

  -- then this Qry should present you with the columns Sname, Mname and cServ as identical, kInst should be empty.

  -- if you are connected to a named instance, then

  -- this Qry should result in

  -- Sname and cServ are identical

  -- Mname is the machine name

  -- kInst is the named instance.

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
