BUG #: 57901 (SQLBUG_70)
After applying SQL Server 7.0 Service Pack 2, a user may receive the following error message when using the OPENROWSET Transact-SQL function:
This can occur even when Ad Hoc Query Access has been explicitly allowed for the OLE DB provider being used.
7415 - Ad hoc access to OLE DB provider '%ls' has been denied. You must access this provider through a linked server.
The OPENROWSET function will succeed most of the time, but the error may occur a small amount of the time. The registry value DisallowAdhocAccess may also have to be added, depending on how the clients are connecting to SQL Server; see the table in the "More Information" section of this article for additional information.
A change was made in SQL Server 7.0 Service Pack 2 as detailed in the following article in the Microsoft Knowledge Base:
256052This altered the security behavior of the OPENROWSET function depending on the registry value of DisallowAdhocAccess for each OLE DB provider.
