Windows Server 2003 R2 Directory Connection Problem

Question

I am trying with this application to read a .jpg file on a remote Server Windows Server 2003 R2.

For this in a WebForm project occupy NetworkConnection

Intuitively I have given value to some parameters that are occupied but I have doubt with them

using (NetworkConnection nc = new NetworkConnection(localName, networkName, objnetCred))

localName = "F:" << I doubt where I can find this value in my network and which it would be its format

networkName = "servidor_99" << I doubt where I can find this value in my network and which it would be its format

objnetCred =

Domain "999.999.99.999" << I doubt where I can find this value in my network and which it would be its format

Password "xxxxxxxxxx"

UserName "usernamexxx"

var result = WNetAddConnection2(
            netResource,
            credentials.Password,
            credentials.UserName,
            flags);

netResource

Comment null

Display Type Share

LocalName "F:"

Provider null

RemoteName "servidor_99"

ResourceType Disk

Scope GlobalNetwork

Usage 0

credentials.Password "xxxxxxxxxx"

credentials.UserName "usernamexxx"

flags 1

With these values ​​I get the error:

The result value is equal to 67

The specified network name is not found

I would appreciate some guidance in this regard

Regards
