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.

Perhaps the easiest way (as crazy as this sounds and as code-smelly as it looks) is to just run DBCC CHECKIDENT twice like this:

-- sets all the seeds to 1
exec sp_MSforeachtable @command1 = 'DBCC CHECKIDENT (''?'', RESEED, 1)'

-- run it again to get MSSQL to figure out the MAX/NEXT seed automatically
exec sp_MSforeachtable @command1 = 'DBCC CHECKIDENT (''?'')'

Done.

If you want, you can run it once more to see what all the seeds were set to:

-- run it again to display what the seeds are now set to
exec sp_MSforeachtable @command1 = 'DBCC CHECKIDENT (''?'')'

This is just a creative way to take advantage of the comment from the documentation:

If the current identity value for a table is less than the maximum identity value stored in the identity column, it is reset using the maximum value in the identity column.
