hyt 0 Report post Posted April 12, 2010 We are trying to attach the DB to MS SQL Server Management studio express, but everytime we click on the add button we get the same error. Failed to retrieve data for the request. (Microsoft.sqlServer.Express.SmoEnum) Sekadar nak share pengetahuan.. Problem ni kalau user guna operating system vista. Vista perlukan permission kalau nak run apa-apa new application yang baru install. so solution klik kiri kat icon sql server --> Properties --> Compatibility --> Check pada Run this program as an administrator Quote Share this post Link to post Share on other sites
