Read/write files in shared drive from web application hosted on iis

Question

We have two server in same domain. On one server (SERVER1) we have folder "C:\\AppFiles\\Production\\Inbound" and shared AppFiles folder as a drive (AppFiles (O:)) to another server (SERVER2) and we are manually able to place files in shared drive (O:\\Production\\Inbound) on SERVER2. But we want to read/write files in shared drive (O:\\Production\\Inbound) from our mvc web application hosted on SERVER2.

We are getting below error in provided code when try to read/write in shared drive (O:\\Production\\

 public void Writefile()
 {
  System.IO.File.WriteAllText(Path.Combine(@"O:\Production\Inbound", "testlog.txt"), "test test, text");
 }

error:

Could not find a part of the path 'O:\\Production\\Inbound\\testlog.txt'.

Please suggest how i can read/write files in shared drive from application hosted on iis.

Answer 1

Mapped drives are not supported on IIS, rather you can use UNC paths. Try changing the path to the following:

\\SERVER1\C$\AppFiles\Production\Inbound

If both the servers are on the same network and you can access the above link from server 2, the it should work.
