1. log on to the MSSQL database and select "security"-> Create a login name,

2. Select "Search"-> select a user or group-> "advanced"-> select a user or group-> select "Search now" to find ASPnet in the list, click OK ..

3. After creating a login name, you need to set the user ing for this user, select "machine name \ ASPnet" Login Name, right-click the attribute, and the following dialog box appears, the above is the database associated with you, and the lower is to select the database role member identity, select the two indicated by the Red Arrow should be OK ..

4. Run the page again and click OK ..

5. Conclusion: if the above two problems occur, You can first register IIS, and then add the ASPNET login name with the corresponding "Identity" attached ".
