Access a file from the network

[raghulvarma]

I have to access a XML file in the network and do the changes in the file and then save that file back.
The coding that I have used is
xdConfiguration = New XmlDocument
xdConfiguration .Load("\\XXX\YY YYY\forTest.xml ")
but when I try to load that particular file exception is thrown stating
Logon failure: unknown user name or bad password.
Note: The file I am accessing is been given full permission , I have also given impersonation but I am geting the above mentioned problem
How to solve this issue??
