It's a bit hard to tell from your description, but I'm assuming that [xxxxxx] is a table. Is this correct? If so, you'll either need to specify the schema after the database name (so it'll come out as TestDB.dbo.TestTable, for example; the schema will be the little prefix before the table name in the database list).

This would be my guess from your description; the fact that the DBCC and sp_help commands worked despite the missing schema specification is quite strange, though. More details will be needed if this doesn't work out.
