When and Who created linked server? I came across a linked server that is pointing to production from test environment with full access. Is there a way to find out who and when this linked server was created? Based on last modified date, I came to know this was created long back so but with least hope I took a look into default trace - as expected there is no luck.

My test server version is 2008R2.
The sys.servers data dictionary view will give you the date that the Linked Server entry was modified/created (modify_date column), but not who created it.
