SQL 2012 :: Import XML File In Table

I want to import an XML file in an Table. The XML file is on an Other Network location than the Database server I’m connected to and I have access to this location with my windows Credential.

I connect from my local PC to the Database server “RS1” with my Windows Credentials.

There I run this script

CREATE TABLE XMLwithOpenXML
(
Id INT IDENTITY PRIMARY KEY,
XMLData XML,
LoadedDateTime DATETIME
)
INSERT INTO XMLwithOpenXML(XMLData, LoadedDateTime)
SELECT CONVERT(XML, BulkColumn) AS BulkColumn, GETDATE()
FROM OPENROWSET(BULK '<Networkname><MAP>Name_.xml', SINGLE_BLOB) AS x;

I Get the error:

Msg 4861, Level 16, State 1, Line 10
Cannot bulk load because the file "<Networkname><MAP>Name_.xml'" could not be opened. Operating system error code 5(Access is denied.).

(<Networkname><MAP>Name_.xml' is not the real name )

So it looks like the openrowset connects to the network location with other credentials.

Where I can find (and change) the credentials which is used to connect to the network location?

I found this article on MSDN (Security Considerations) but cannot find solution [URL] .....
