title: Can't import dump from mapped net drive using data pump
body: <p>I'm trying to import few users from .dmp file from a net drive. Unofrtunately it seems that I lack some rights to do so since I get</p>
  
  <pre><code>ORA-39001: invalid argument value
  ORA-39000: bad dump file specification
  ORA-31640: unable to open dump file "\\net\drive\directory\placeholder\my_dump.dmp" for read
  ORA-27041: unable to open file
  OSD-04002: unable to open file
  O/S-Error: (OS 5) Access is denied.
  </code></pre>
  
  <p>I'm not sure why, because I can both access that directory, and for example save a txt file there.</p>
  
  <p>Directory is saved on database as '\net\drive\directory\placeholder'. Log file has other directory specified (not on net drive).</p>
  
  <p>Is there any workaround to import this dump without actually moving it to local drive? Dump is really big, and I don't have space for it (not even close) and neither can I (probably) change my rights on this mapped drive.</p>
  
  <p>Also I can't really make dump smaller.</p>
  
  <p>On one site I've found this advice - " Remember, your OS user ID may not be the ID that is running a submitted RMAN job, in an operating system, UNIX, Linux or Windows."
  The solution was to "</p>
  
  <pre><code>In the ControlPanel services:  
  Right click on service
  Select ?properties?
  Select ?logon?
  Change the default user ID to an Oracle user with Windows administrator privileges"
  </code></pre>
  
  <p>But I'm not sure what changing this would actually do to server/database, and I'm working on client's server so I don't want to act rashly. I also don't want to reset database or server itself.</p>
  
  <p>Any help with what should I do? </p>
