TITLE: Locate Database Files - MICROSOFT

 

D:\abc\WebSite\ASP_NET\TTGS\TTGS\App_Data

Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists.

 

If you know that the service account can access a specific file, type in the full path for the file in the File Name control in the Locate dialog box.
