How i can export and distribute setting; network.automatic-ntlm-auth.trusted-uris" to all computers in the network (With Folder Rederiction enabled)?

Question

Hi,
We are about to enable SSO in our environment. As a result, I need to modify the value for user_pref("network.automatic-ntlm-auth.trusted-uris", "my domain");>>prefs.js.
I created a simple .bat file to make the necessary mod and add the line to pref.js. When I run the file it outputs the prefs.js to the same location, not the Mozilla AppData folder. We are a Win7 environment with folder redirection enabled. Therefore, our user's Mozilla AppData folder is located at \\my domain\dfs\XenDesktop\Profiles\username\AppData\Mozilla\Firefox\Profiles\default (random default profile name). My question is what is the best course of action to add this pref. to all PC user's pref.js file? keep in mind the pref.js is located on the hidden network path I included above. I apologize if my question is not easy to understand.

cor-el, thanks for you reply.
Yesterday, prior to my post, I did try the mozilla.cfg method. I read your reply to another FF user's, similar question. Here are my complete steps.
1. created a txt file with the following info: defaultPref("network.automatic-ntlm-auth.trusted-uris", "ngs.org"); // set new default value
2. saved the file as mozilla.cfg
3. dropped the file in C:\Program Files (x86)\Mozilla Firefox
4. Created local-settings.js with the following info:
pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift
5. dropped the file in C:\Program Files (x86)\Mozilla Firefox\defaults\pref
When I launch Firefox the network.automatic-ntlm-auth.trusted-uris should say ngs.org, but the value is still blank.
Any help is greatly appreciated.
