If you are working in Query Analyzer you can look in the sysobjects, syscolumns, and systypes tables. To get the name you can use this example, but you will need to add type and length.
select SO.Id,
TableName = SO.Name,
ColumnName = SC.name
from Sysobjects SO
Inner join Syscolumns SC on SO.id = SC.id
where SO.TYpe = 'U'
order by SO.Name
