See sample below. Note that although no NS prefix is defined on your sample
XML, I define "ns1" as local prefix for the NS. The prefix (or local name)
does not matter, but the NS the prefix stands for. That's why you would need
to modify your program, if the NS would change in the future.

I've read the documentation on XmlNamespaceManager, but I can't figure out
how to implement in my code. Could you please show me an example?

SelectSingleNode when working with XML documents that use namespaces. For
more information see the online help for XmlNamespaceManager.
(2) xmlns is not a normal attribute, it defines a namespace. If the
namespace changes, it normaly means that the semantics of the XML might
have changed. In your expample <Config> and <site> ar bound to the (default)
namespace "http://www.mysite.com/Transfer/". If this changes to something
other, then you would also need to change your code, where you add the
namespace to the XmlNamespaceManager.
