Because server events and service objects are running in the context of a windows service, there are two things to consider when trying to accessing files on other systems from this code:

1) You don't have access to mapped drives.  If you want to access a remote share, access it using the full unc path, such as 192.168.0.10ShareFilename.txt  or fileserversharefilename.txt

2) You will need to provide security access to those shares to the user that the K2HostServer is running under.
