Convert the number "67,1219" to hexadecimal. Look for a matching value in winerror.h. If you don't find a matching value, try stripping away the top 16 bits to just be left with the bottom 16 bits. Convert to decimal and then again look in Winerror.h to find a match.

In general, if the current user has access the file share, you don't even need to use your NetworkConnection class. Simply use File.Copy() to copy into the file share. It's when the current user doesn't have access to the fileshare and you need to use a different set of credentials when you need to establish a network file connection.
