Problem with Database diagram

Dear all, I install SQL Server 2008 R2 on Win7 ,and after I created database and tables,When I click the New Database Diagram this message appeared : **Database diagram support objects cannot be installed because this database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects.** I checked the owner and its valid ...any idea ??

Is the user you're trying to set as the owner a sysadmin? If not you may have to recreate the login mapping to the database in question.

It might be worth just running the command to see if it fixes any broken 'links' alter authorization on database::YourDatabaseName to YourValidUser Also, are you creating the database from new, or have you restored/attached a previous one? If so you may need to check the compatibility level.

I solved the problem by change the login from win auth to SQL server auth [sa] and use the command : alter authorization on database::TEST to [sa] But with Win auth doesn't work If I use win login and the command is :- alter authorization on database::TEST to [HPDV6-HP\HP DV6]

if IIRC, for the very first use of Database Diagram Designer, it must be set up by a member of the db_owner role, otherwise it would not work.
