Problem connecting to database - "already opened exclusively by another user, or you need permission

[Tom Wild]

Hi

I am trying to connect to an Access database from a WebPage in VB.Net but
when I try to open the connection I get the following error:

The Microsoft Jet database engine cannot open the file
'C:\Test03\Test03.mdb'. It is already opened exclusively by another user, or
you need permission to view its data

My connection string is as follows:

Provider=Microsoft.Jet.OLEDB.4.0;Password="";User ID=Admin;Data
Source=C:\Test03\Test03.mdb;Mode=Share Deny None;Extended Properties="";Jet
OLEDB:System database="";Jet OLEDB:Registry Path="";Jet OLEDBatabase
Password="";Jet OLEDB:Engine Type=5;Jet OLEDBatabase Locking Mode=1;Jet
OLEDB:Global Partial Bulk Ops=2;Jet OLEDB:Global Bulk Transactions=1;Jet
OLEDB:New Database Password="";Jet OLEDB:Create System Database=False;Jet
OLEDB:Encrypt Database=False;Jet OLEDBon't Copy Locale on
Compact=False;Jet OLEDB:Compact Without Replica Repair=False;Jet
OLEDB:SFP=False

Can anyone suggest what I am doing wrong?
