SQL Server Reset Identity Increment for all tables

Question

Basically I need to reset Identity Increment for all tables to its original. Here I tried some code, but it fails.

Another way of using sp_MSForEachTable and checking whether or not the Table has an identity value before resetting it:

EXEC sp_MSForEachTable '
 Print ''?''
 IF OBJECTPROPERTY(object_id(''?''), ''TableHasIdentity'') = 1
  DBCC CHECKIDENT (''?'', RESEED, 0)
 else
  Print ''Table does not have an identity value''
'

NOTE: If you want the identity value to start at 1 then the DBCC command should use CHECKIDENT (''?'', RESEED, 0) not CHECKIDENT (''?'', RESEED, 1) as indicated in some of the answers. Quote from MS SQL Server documentation:

The following example forces the current identity value in the AddressTypeID column in the AddressType table to a value of 10. Because the table has existing rows, the next row inserted will use 11 as the value, that is, the new current increment value defined for the column value plus 1

USE AdventureWorks2012;
GO
DBCC CHECKIDENT ('Person.AddressType', RESEED, 10);
GO
