Answer 1

Confirm you can view the place you are looking to save to. Then update your code

String serverLocation = @"\\servername\";

if (File.Exists(serverLocation +@"Users\xxx\xxx.pdf"))
{
    MessageBox.Show("xx.", "xx");
}
else
{
    Directory.CreateDirectory(serverLocation +@"Users\xx);
    PdfWriter.GetInstance(pdfDosya, new FileStream(serverLocation +@"Users\xx\xx.pdf", FileMode.Create));
}

As mentioned in comments, when you use @ you do not need to escape your \\'s.

Answer 2

Probably, the only difference would be your authentication into the server before save any file.

The easiest way to do that, would be using "User Impersonation".

Install it in your application

https://www.nuget.org/packages/UserImpersonation/

Install-Package UserImpersonation -Version 1.0.0

A Quick example with "User Impersonation DLL"

using (UserImpersonation obj = new UserImpersonation("YourUserNameToAccessTheServer", "YourDomain", "UserPassword"))
{
   string YourDirectoryFullNameExample = "\\ServerName\\Folder1\\Folder2\\File.Pdf"
   if (File.Exists(YourDirectoryFullNameExample))
   {
      MessageBox.Show("xx.", "xx");
   }
   else
   {
      Directory.CreateDirectory(@"YourDirectoryFullNameExample);
      PdfWriter.GetInstance(pdfDosya, new FileStream(YourDirectoryFullNameExample, FileMode.Create));
   }
}
