Commented Unassigned: computername\username Access denied [12373]

Hi,

Since version Release 2.5.17 I'm unable to schedule a task using "computername\username"
This worked in version Release 2.4.2

Example:
Computer is Lan
User is LanUser

Please note that it's a local admin account (not domain)
Trying to log in with Lan\LanUser fails with "Access is denied"

I think I have this addressed. I have posted code with the fix as an attached file for this issue. Will you please test and confirm?
