I'm making NUNit-tests. I'm testing triggers. Triggeramount is around 200. I make a insert/update/delete-statement and afterwards a select-statement to see if the trigger has done his job. At 75% of the tests I get an error: Something like : "[DBNETLIB][ConnectionOpen." (Connect()).] SQLServer does not exists or access denied." It also seems if my SqlServer are treaterd very slow at 75% of the tests. I think I execute around 3000 sqlstatements. Can anyone help me?
