Problems reading UNC paths from impersonated asp.net using vb

Basically, i'm trying to write a file to people's home directory using VB/ASP.NET

I run this code:
(note: M_Util.Debug_Write is a function that writes to a file I can tail/read)
Dim wi As WindowsIdentity = CType(User.Identity, WindowsIdentity)
M_Util.Debug_Write(wi.GetCurrent().Name)
M_Util.Debug_Write(System.Threading.Thread.CurrentPrincipal.Identity.Name)
Dim wic As WindowsImpersonationContext = wi.Impersonate()
M_Util.Debug_Write(wi.GetCurrent().Name)
M_Util.Debug_Write(System.Threading.Thread.CurrentPrincipal.Identity.Name)
M_Util.Debug_Write(Directory.Exists(Server.MapPath("/"))) 'Web server app root
M_Util.Debug_Write(Directory.Exists("C:\")) 'web server c
M_Util.Debug_Write(Directory.Exists("\\myfileserver\transit")) 'transit drive share
M_Util.Debug_Write(Directory.Exists("\\10.0.0.40\transit")) 'transit drive share (by ip)
M_Util.Debug_Write(Directory.Exists("\\10.0.0.40\transit\test")) 'transit drive folder (by ip)
M_Util.Debug_Write(Directory.Exists("\\mypc\c$")) 'my pc
M_Util.Debug_Write(Directory.Exists("\\10.0.0.51\c$"))'my pc (ip)
wic.Undo()
M_Util.Debug_Write(wi.GetCurrent().Name)
M_Util.Debug_Write(System.Threading.Thread.CurrentPrincipal.Identity.Name)

Open in new window

and it outputs this:
"NT AUTHORITY\NETWORK SERVICE"
"MYDOMAIN\myuser"
"MYDOMAIN\myuser"
"MYDOMAIN\myuser"
"True"
"True"
"False"
"False"
"False"
"False"
"False"
"NT AUTHORITY\NETWORK SERVICE"
"MYDOMAIN\myuser"

Open in new window

it's worth also noting that i've tried just writing to a text file in all those locations just in case it was the Directory.Exists command

No luck of course

Basically, the impersonation only works when using it on the webserver.
