That's one I've never seen before.

I found this in Books Online:

When you are detaching or attaching a database, the Database Engine tries
to impersonate the Windows account of the connection performing the
operation to guarantee that the account has permission to access the
database and log files. For mixed security accounts that use SQL Server
logins, the impersonation might fail.

I don't really know what is going on, but there might be some issue with
your Windows account.

How are you logged into SQL Server: Windows authentication or SQL
authentication?

Are you in a workgroup or a domain?

What is the service account for SQL Server? Does the service account have
Windows permission to impersonate you?
