I see a constraint in my table thats not in INFORMATION SCHEMA? When I expand the database "Constraints" object, I see 2 of them named DF_DocumentD_Docum_3F466844 and df_documentdistqty, but when I select to view everything from the "Information Schema.TABLE Constraints", the constraints named above dont show up, any idea why? 
I scripted out these constraint and it has the following info:

ALTER TABLE [dbo].[DocumentDistribution] ADD  DEFAULT (getdate()) FOR [DocumentDistDate]
GO


and the other has:

IF  EXISTS (SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID(N'[df_documentdistqty]') AND type = 'D')
BEGIN
ALTER TABLE [dbo].[DocumentDistribution] DROP CONSTRAINT [df_documentdistqty]
END
Please stop using INFORMATION_SCHEMA and deprecated backward compatibility views like sysobjects. This is just another in the long list of things that INFORMATION_SCHEMA is missing in order to provide a complete picture of your metadata. See this post for a more exhaustive list:


The case against INFORMATION_SCHEMA views


To find the name of the default constraints for any table, use the catalog view sys.default_constraints:

SELECT [constraint] = df.name, [column] = c.name, df.[definition]
  FROM sys.default_constraints AS df
  INNER JOIN sys.tables AS t
    ON df.parent_object_id = t.[object_id]
  INNER JOIN sys.columns AS c
    ON t.[object_id] = c.[object_id]
    AND df.parent_column_id = c.column_id
  INNER JOIN sys.schemas AS s
    ON s.[schema_id] = t.[schema_id]
  WHERE s.name = N'dbo'
  AND t.name = N'DocumentDistribution';
