Hi,

   I moved my DDN project from old domain to new domain. I just took backup of both database and code and created project on new server. But now unable to log in , I can create new user that I see in DB but still not able to log in with either of the user details. 

   Reason for migration is I have to upgrade from DNN6 to DNN7 and also need to add some functionality. Thats why have to move it on dev.

              Please help me to resolve this issue.

Thanks,

Be sure the 'Maschine Key' on your web.config file would NOT be changed and is still the same as on your old instance.  Be sure the Login Name on the new SQL Servers Database User is added.  Check it using the SQL Management Studio, go to Database/Security/Users/ and check the Settings of the DatabaseUser you are using.  The Login Name should not be empty!  The Login Name could be found on the SQL Servers Security tab.

To Change the user Login you can use this on SQL Management Studio with a  new Query:

/***Start Script***/

use <your databaseName>

EXEC sp_change_users_login  'Update_One', '<your db UserName>', '<your SQL Server LoginName>';

/***End Script***/
