How to programmatically discover mapped network drives on system and their server names?

Question

I\'m trying to find out how to programmatically (I\'m using C#) determine the name (or i.p.) of servers to which my workstation has current maps. In other words, at some po

I've found yet another way of doing this, which uses part of the technique sixlettervariables posted. I'd love some feedback about the pros and cons of the various techniques. For example, does mine have a downside, a scenario where it won't work, for instance?

[DllImport("mpr.dll")]
static extern uint WNetGetConnection(string lpLocalName, StringBuilder lpRemoteName, ref int lpnLength);

internal static bool IsLocalDrive(String driveName)
{
    bool isLocal = true;  // assume local until disproved

    // strip trailing backslashes from driveName
    driveName = driveName.Substring(0, 2);

    int length = 256; // to be on safe side 
    StringBuilder networkShare = new StringBuilder(length);
    uint status = WNetGetConnection(driveName, networkShare, ref length);

    // does a network share exist for this drive?
    if (networkShare.Length != 0)
    {
        // now networkShare contains a UNC path in format \\MachineName\ShareName
        // retrieve the MachineName portion
        String shareName = networkShare.ToString();
        string[] splitShares = shareName.Split('\\');
        // the 3rd array element now contains the machine name
        if (Environment.MachineName == splitShares[2])
            isLocal = true;
        else
            isLocal = false;
    }

    return isLocal;
}

This is called from this code:

DriveInfo[] drives = DriveInfo.GetDrives();
foreach (DriveInfo drive in drives)
{
    bool isLocal = IsLocalDrive(drive.Name);
    if (isLocal)
    {
         // do whatever
    }
}
