If an error is displayed saying there is a Logon failure then it is possible that the user trying to connect
to the share does not have the correct permissions.
To check permissions, on the MyCalls server, right click on the MyCalls folder in C:\Program
Files\NEC Infrontia and then Sharing and Security.
On the security tab, make sure the user or group that is accessing the share has the Read and
Execute permission to the share.
