I am trying to copy a file to a network drive.  I can do it on the
domain controller/web server but not from a client.  Here is the code:

   Dim impersonationContext As
System.Security.Principal.WindowsImpersonationContext
   Dim currentWindowsIdentity As System.Security.Principal.WindowsIdentity
   currentWindowsIdentity =
CType(User.Identity,System.Security.Principal.WindowsIdentity)
   impersonationContext = currentWindowsIdentity.Impersonate()
   dim Temp as string="TestFile"
   File.Copy("\\MyServer\Template.doc", "\\MyServer\" & Temp &".doc")

   impersonationContext.Undo()

I get the error "System.IO.FileNotFoundException: Could not find file
\\Server\File..." when running it from the [authenticated] client
browser.   I searched everywhere on the web and MSDN on this error but found
nothing.  The error it occurs on the file copy statement The file.copy
statement is trying to copy a file on a different server than the web
server.

Any help is appreciated.
