I have read your post.
Please let us know out of the 20 computers in which you have the stated issue, how many computers run the Windows 2000 Operating system.
As an resolution to the existing problem, you can create a new McAfee policy in the McAfee Online security center console and disable the "Scan mapped network drives" option in that new policy and then add those 20 computers alone to this new policy and then try if the scan is not repeated in the schedule scans.
Please also answer the question of the operating systems on these 20 computers.
Thanks for your reply Pritish...
Looks like its a Windows 2000 issue - the machines that ignore the "don't scan mapped drives" setting are all running 2000 OS.
Shall I try creating a new policy for these PC's or is it simply an OS incompatibility?
I know its an old operating system, but these users run old bespoke legacy applications that run nicely on 2000.
what do you recommend?
I have read your reply.
Please be informed that McAfee has stopped support to all Windows 2000 operating systems. This is fully effective from the roll-out of the McAfee SaaS Endpoint protection v5.2.
That is the reason the software and the policy works well on the XP computers but does not apply/work on the computers with the Windows 2000 OS. This is mainly due to non-compatability.
Since Microsoft has stopped it's support to Windows 2000 OS, McAfee has also stopped it's products from supporting the OS. You need to upgrade from the Windows 2000 Operating system to get continued protection from McAfee products.
