SCHTASKS can't administer remote tasks

Question

I am trying to stop and then disable a remote task from a build script. The remote server is Server 2k8. The client running the script is Windows 7. Both machines are joined to the domain.

When I run schtasks /Change /S remoteServer /TN "theTask", I get an error ERROR: The specified task name "theTask" does not exist in the system. If I run this command locally, everything works. I've verified that the domain user account I am logged into on my computer has administrator privileges to the remote computer.

If I run schtasks /Query on the remote computer, I get a listing of all scheduled tasks. If I run the same command remotely with the /S switch, only two legacy tasks (Google update tasks) return.

My initial thought was that this could be a permissions error, but when I try to run schtasks using the /u switch, I get ERROR: The request is not supported, which makes no sense because both the client and server are running the modern version of windows scheduler. I'm very confused.

What do I need to do to allow schtasks remote access to ALL the tasks on a server?

Edit: schtasks seems to only be returning the list of "v1" style tasks.

Solution

Found it! Turn off windows firewall or enable the Remote Scheduled Tasks Management firewall exception.

copying a different version of the scheduled tasks executable wouldn't be considered best practice. This also doesn't answer the questions as to why a remote server fails to return the correct information when queried.

This did not work for me. Also, this does not explain why some tasks are returned and not others.

Specially port 135.
