Cannot find file Exception with FileStream, opens in Explorer

I have the following code:

FileStream file = new FileStream(@"\\srv\dscan$\001\unknown\2012-04\0011200001001700_001.pdf", System.IO.FileMode.Open);

It always throws a FileNotFoundException. The strange thing is that if I paste the exact same path above into Windows Explorer, the file can be found and opened perfectly OK.

What can be causing this? Is there a special way of handling file streams on shared network drives?

What Darin Dimitrov says.

The user account that you are logged in under in Windows seems to have the sufficient permissions or maybe you have entered a username and password before which you marked as 'remember'.

When running your code it probably does under minimal rights (UAC) or maybe you are creating a Windows Service, which runs under a different account all together.

Problem could also be related to the dollar sign, which indicates that you are trying to reach a hidden share. I don't know if that is a problem in itself, but could have impact on your (in)sufficient rights.

C# treats a path differently from a windows explorer. And one more thing, if you check those posts: Reading File From Network Location

you will find that you need some more work on the configurations.

What can be causing this?

The account under which is executing the process containing this code doesn't have sufficient permissions to read from this location.
