title: Drive Info Not Returned Correctly When Run As A WCF Service
body: <p>I have a WCF service that returns the number of local drives reported on my local PC.</p>
  
  <p>I have the following drives:</p>
  
  <p>C: Local Disk
  D: DVD Drive
  X: Network Drive
  Y: Network Drive</p>
  
  <p>When I run the WCF service using the WCF test client I get the correct drive count of 4 drives.</p>
  
  <p>If I try to connect to the WCF service using Silverlight or VB.NET I only get 2 drives returned, the drives X: &amp; Y: (network drives) are missing.</p>
  
  <p>I have a sample of the code below, please can anyone help me with this problem?</p>
  
  <pre><code>Dim Info As DriveInfo
  
  Dim Count As Integer
  
  For Each Info In My.Computer.FileSystem.Drives
  
    Count = My.Computer.FileSystem.Drives.Count 
  
  Next Info
  </code></pre>
