You're saying that you have user settings that you want to apply to users only when they logon to certain computers? Sounds difficult, eh? It's not difficult at all. It sounds like a job for loopback group policy processing!
Assume the following:
[Domain] mydomain.com.org.net.local
|
|--[OU] Special Computers
| |
| |-- [Computer] COMPUTER 1
| |
| |-- [Computer] COMPUTER 2
| ...
|
|--[OU] User Accounts
|
|--[User] Bob
|
|--[User] Alice
...
You would like to apply a user setting (such as running a logon script, or applying other types of GPO user settings) for all users who logon to computers in the "Special Computers" OU. When they logon to computers located in other OUs, though, you do not want these special settings to apply.
Create and link a GPO to the "Special Computers" OU. Specify in that GPO all the user-related settings you want to apply.
("But wait, Evan! The user's account objects aren't in the 'Special Computers' OU!" Yes. I know that. Stay w/ me here. Most AD admins I've met don't understand loopback policy processing and get scared. I've seen horrible hacks like creating secondary user accounts for users to logon with when using "special computers", etc... >shudder<)
In the GPO you created, go into the COMPUTER "Administrative Templates", "System", "Group Policy", and locate the setting "User Group Policy loopback processing mode". Enable this setting. In the "Mode" box, choose "Replace" if you want all the user's "normal" group policy settings to be ignored and only the user policy settings in this new GPO to apply. Choose "Merge" if you want the user settings in the GPO to apply after all their normal user settings have applied.
My opinion is that this is a lot cleaner than "hacks" involving "If computer == blah" in logon scripts.
My advice to you would be to do what you're doing with a Group Policy Preference (GPP)registry settings, rather than with a logon script. It will apply one time, leaving default settings in the users' registry, but the user will be able to change the settings freely in the future without having them "smashed" each time they logon.
If these are Windows Server 2008 machines, like your tag says, then there's really no excuse not to use GPP registry settings. Have a look at the articles below for some more details. This is a really nice feature of W2K8, and something you should be taking advantage of.

It was actually lack of memory, as it turns out. Restarting the server and freeing up 16Gb again, allowed it to be run after all. No issues with user permissions. No issues with user credentials. It was just a weird memory problem (I noticed something was up when I couldn't start SQL Configuration Manager or successfully install any Updates through Windows Update).
I'm guessing that Task Scheduler didn't have permission to take back RAM, whereas the admin user running the .bat by hand, did.
Can of worms: Opened. *sob*

I've never seen this particular issue, but you can sort out file associations with Group Policy Preferences. Either:
or
Computer config gives you full configuration options similar to manually changing it in Folder Options on the machine. User config just gives you an "Execute" option which you can set as default.
Computer config would be the preferred - just go onto a working machine and duplicate the settings. I think this would work for you, but you'll need to experiment:
Alternatively, as @uSlackr, run it as a batch script and call the VBS. Though that's more a workaround rather than a fix in my opinion.
