Attach and Detach Database Errors

  • Control Panel ->
  • System and Security ->
  • Administrative Tools ->
  • Services ->
  • Double Click SQL Server (SQLEXPRESS) -> right click, Properties
  • Select Log On Tab
  • Select "Local System Account" (the default was some obtuse Windows System account)
  • -> OK
  • right click, Stop
  • right click, Start

Voilá !


I used get a permission Error that sql server won't able to access a database to be attached. This helped me.
