Unable to start application to connect to Access database

[CM Manager via DotNetMonster.com]

I am very frustrated due to this exception error I am receiving. I've tried
searching numerous user support groups, Microsoft Support Net, Google, etc.
and haven't found exactly my situation. Hopefully someone here can help.

I am just learning VB.NET and purchased the SAM's "Teach Yourself VB.NET
2003 in 21 days' book. I am trying to connect to an Access database I created
locally on my computer per Chapter 16. I originally had it on a network share
but have also tried accessing it on my C:\ drive. I've created an
OleDBConnection1 along with the OleDbDataAdapter1 and the DataSet11 per the
book's instructions. I dragged a data grid onto a blank form and in the
Properties window set its Datasource > DataSet11.Students which is the name
of my Access table (Students.mdb).

I am receiving an error message stating "An unhandled exception of type
'System.Security.SecurityException' occurred in DatabaseTests.exe

Additional information: Request failed" I've seen this probably has something
to do with my permissions which I can adjust in the Microsoft .NET Framework
Configuration utility, but I don't know what I'm looking for. Can someone
please assist with troubleshooting this issue? Let me know if you need any
additional information. Thank you!

By default ASP.NET runs under the ASPNET account.
Make sure this user account has read/write permissions to the MDB file.

Alternately you could use impersonation to have ASP.NET run under a
different account that has the necessary permissions.
Here's more info on impersonation:

You don't mention ASP.NET but I will assume this is the type of project you are working with since
you posted in this newsgroup.

See the following MS KB article:
