I've a .net 2.0 app.  One of the pages contains a treeview control that displays folders on the c: drive.  

The following code snippet shows how I populate the nodes of the treeview with the folders and files.  

When a document link is highlighted it shows the following code:
__doPostBack('ctl00$ContentPlaceHolder1$TreeView1','sC:*|*MainFolder*|*SubFolder*|*\\C:*|*MainFolder*|*SubFolder*|*SubSubFolder/\\C:*|*MainFolder*|*SubFolder*|*SubSubFolder/AnotherFolder/\\C:*|*MainFolder*|*SubFolder*|*SubSubFolder*|*AnotherFolder*|*doc.pdf')

On my local computer the documents open no problem, however on the server it has issues understanding this complex string of information to locate and open the file.  What can I do to correct this issue?

foreach (DirectoryInfo subFolder in subFolders)
            {
                TreeNode child = AddNodeAndDescendents(subFolder, node);
                child.Text = subFolder.Name + " - last modified on " + subFolder.LastWriteTime;
 
                foreach (FileInfo file in subFolder.GetFiles())
                {
 
                    int index = file.FullName.LastIndexOf("\\");
                    string strname = file.FullName.Substring(index + 1);
                    string[] name = strname.Split('.');
 
                    TreeNode tn = new TreeNode();
                    tn = new TreeNode(name[0], file.FullName);
 
                    tn.Text = "last modified on " + file.LastWriteTime + "<table style='border:0px; border-collapse:collapse;'><tr><td style='width:600px' nowrap> " + file.Name + " " + file.Length.ToString() + " bytes</td></tr></table>";
 
                    child.ChildNodes.Add(tn);
 
                }
 
                node.ChildNodes.Add(child);
            }

Frankly, I'm not sure of anything.  I've been working to resolve this problem for days now and can't figure it out.  Here's the latest:

Let me say that I've tried to resolve the issue with not using response.redirect (and any other suggested solutions out there that are similar) but this has not resolved the issue.

When a document link is clicked in the treeview control the document opens just fine if the app is run in VS2008 however when run through IIS I get the error mentioned in the subject line.  When running the app through VS2008 the docs open fine however the Output window does show the same error message.  

See my complete code below.
