connection sql server

[Guest]

I have an app using mdb file as front end and SQL server as back end.
It suddenly gets following message

"Could not excute the query could not find linked table [Microsoft][ODBC SQL
serverdriver] [SQL server] invalide object name dbo.MyTable (#208)
[Microsoft][ODBC SQL serverdriver] [SQL server] statements could not prepared
(#8180)"

It was working fine.
I am able to connect read table using adp file which menas server is
accessable.
It was working which means the object name exists.

It seems the connect broken suddenly.

Any suggestions?

Thanks millions,

I think that my database chnage owner by itself. I am not database owner
anymore.
Are there any operation can chnage the owner of the database?
Are there any way to reset the owner roghts of database?
