Capture Username and Host name linked to created Table

l want to select all objects that are older than three months and map the object to
the user,machine. We are using Nt authentication.How do l do that ??????

Reason why l want to do that is so that l can calculate space usage and number of
objects owned and group them by user and to flag objects older than 3 months so
l can archive them....

Select
Name
,Crdate
,SYSTEM_USER As UserName
,HOST_NAME() As MachineName
From Sysobjects
Where Name like 'TBL_DEV%'
AND ABS(Datediff(m,GetDate()
,crdate)) >= 3
AND type = 'U'
