Cannot create diagrams in SQLSERVER 2005

Hi,
Every time I click on the Database Diagram node in object explorer in SQL
Server Management Studio, I get a message:
Database diagram support objects cannot be installed because this database
does not have a valid owner. ...
I have checked the owner and it coincides with my logon name in my domain
(i.e. DENTDEVELOPMENT\JuanDent). What could be going on? Could I have a
problem with Active Directory? Why am I not being recognized as a valid db
owner?
Thanks in advance,
Juan Dent, M.Sc.
Make sure the compatibility level of the databases is set to
90 - that's often what causes the problem.
You can set it to 90 using:
EXEC sp_dbcmptlevel 'database name', '90'

This typically happens when you migrate a database from another server.
The problem can be seen by SELECT * FROM sys.database_principals. Compare
the row for dbo with a database created on the server.
I think changing the ownership to some other login, and back to yourself
fixes the issues.

Cannot create diagram in SQL 2005

i get the following message

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 am the db owner but still wouldnt let me install and create diagrams.

help!

cheers

I moved this thread from SSIS forum...I hope you can get better luck here...|||

hey i found the answer

you gotta set the owner to sa and then go to the database properties, then options, then change compatibility fromn sql 2000 (80) to sql 2005 (90)

too easy..

thanks buddy
