Restoring 2008 Database with Filestream - Process cannot access file error

I'm trying to restore a copy of a database that has a filestream and am getting the error below. I've tried with move option to specify a new path and left it with default path, neither worked. Did a trace with procmon, didn't see anything. FileStream1 is a new folder that the restore process creates. I've deleted the folder, tried it with a new name, re-took the backup from the source machine, restarted SQL, rebooted the machine, drive permissions are open. I've run out of ideas on how to debug further. Looking up the error online wasn't much help either. Msg 3634, Level 16, State 1, Line 1 The operating system returned the error '32(The process cannot access the file because it is being used by another process.)' while attempting 'OpenFile' on 'X:\Data\FileStream1\4ecb2e48-0eee-4c99-a3f0-f1e6c7f00b24\f2efe374-9481-4c1b-a7f2-dcdcee350807\0000001b-0000aaa6-00f6'.

Linked Server Error 7303 for Access 2003 Database

I am having difficulty creating a linked server to and Access 2003 database on my SQL 2005 server.  Whenever I create a linked server through the either the “New Linked Server” tool in the SQL Management Studio or using the sp_addlinkedserver method, receive and error indicating “Cannot initialize the data source object of the OLE DB provider…(Microsoft SQL Server Error: 7303)”.  Although my ultimate goal is to link to a secure Access 2003 database file, the current MDB file I am trying to link to is “unsecured”.  I have already verified that the SQL Service account has read and write access to the folder containing the MDB file as well as the temp directories on the SQL server (suggestions from other forums).  Is there any SQL Server configuration that I need to modify in order to use the Jet 4.0 linked server provider (Microsoft.Jet.OLEDB.4.0)?

Access web database Reports - "file not found" error


The reports section of my Access web databases aren't working - I keep getting a "file not found" error for every database I upload.  I even tested it with the Northwind Web Database sample from MS.  I could see the reports in Access 2010, so I successfully uploaded the template to my SharePoint 2010 Server, and when I clicked on the links to view the Reports - I got the same "file not found" error for this sample database.

Anyone seen this before?

Error in Uploading Files to Access 2010 Web Database Table with Data Macro


Hi All,


I've recently published an Access 2010 Web Database to the SharePoint 2010 farm in my organization and I'm having the strangest problem.

I have a table which includes an Attachment field. When trying to upload a file through the web I get the following error: "There was an error uploading your attachment to the server".

Now, this table has a "Before Change" Data Macro, which basically executes a simple LookUp of several parameters from another table and writes them back to the "master" table. When deleting this Data Macro, upload on the Web works fine.

The thing is that when working from the local Access file (connected to the SharePoint) and trying to change a field in the table, the following error is received: "The Microsoft Access database engine encountered an error whil

Insert Error not helpful



I am using VS2010

When I try to updated or insert a record in my User table I am getting an error that does not make sense to me and I cannot figure out what is wrong.

Also, when I try to insert a new record I get a validation error saying that the Id is required. However it is an identity field in the db so it should not be necessary to send it to the server.

Could you please shed some light?

Is it possible to to to have this settin

SQL and Outlook: Enable Database Access and Updates Through Exchange and Any E-mail Client


Using Microsoft technologies, you can insert, edit, query, and delete database entries using any e-mail client such as Hotmail, Outlook, Yahoo, or even WAP phone. While e-mail is certainly a powerful and widely used tool, it is usually not integrated with an application for performing any tasks other than sending reminders. The application scenario described here, an e-mail-based SQL update program, uses a simple data model; however, this solution will apply to any data model that you are working with. It will also eliminate the need for complex n-tier Internet applications and serves as a low maintenance solution for providing data access.
