File.Exists(path) returns false on webserver and true on localhost

[Alcar]

Hi,

I am using File.Exists(path) method to determine if a file exists. Locally it works perfectly, but when I deploy it (project-Copy) on the webserver, it doesn't.

string strPath = @&quot;\\<DFS Folder>\<Filename>&quot;;
if(File.Exists(strPath))
{
  // YUPPPIEEEE!
}
else
{
  // NOT A CHANCE!
}

given that both IIS have the same permissions, when I run the program lcally (debug mode) the method returns true, when I run it off the server it returns false.

I have also tried different tests:

path local webserver
-----------------------------------------------------------
\\<dfs servername>\<filename> true false
c:\temp\<filename> true true
o:\temp\<filename> true false
(where o: maps a folder in another server <> webserver)

After alot of research I decided to follow what Microsoft suggests:

FileIOPermission f2 = new FileIOPermission(FileIOPermissionAccess.Read, <path>);

But this didn't change a thing.... any ideas?
