Hello.

At chapter 14 I've got a problem reaching the Database Diagrams, I'm getting an error saying:

"This database does not have a valid dbo user or you do not have permissions to impersonate the dbo user, so database diagramming is not available. Do you want to make yourself the dbo of this database in order to use database diagramming?"
I've tried to answer "yes" to this question, but it doesn't help.

Next message says:
"This server does not have one or more of the database objects required to use database diagramming. Do you wish to create them?
I've tried to answer "yes" here to, but then I'm getting an error message: "Could not obtain information about Windows NT group/user 'KREDINOR/keg', error code 0x54b."

Anything I can do to solve this problem?

Hi there,

Maybe this helps?

Cannot create database diagram - error code 0x54b

Was your machine connected to the domain when you tried this?

The computer I'm using for this book is my work PC and I was trying the database diagram from home and was not logged into the domain. Once I logged in via VPN everything worked fine.

This also is the same problem as another post:
Could not obtain information about windows nt group/user

I guess since the Visual Studio was installed while logged into the domain, I have to be on the domain for this to work? I must admit, I don't know much about domains.
