Polycom RealPresence Desktop – Windows QoS Registry Settings

Last week, I had to call Polycom support for two issues. One of which I mentioned in another post (Automatic Gain Control issue) and the other was because I wanted to find out why their user manual showed some QoS settings that my version did not have access to.

After waiting on hold for ten minutes, the first tech support person I reached was a little cocky, arrogant, smart ass of a prick who was less than helpful with either of my support requests. At one point, he literally told me “we can’t control Windows” (which brings up the question, “Well why in the fuck did Polycom even make software in the first place then?”) in regards to my AGC issue even after I told him that I had disabled all of the Windows settings that take control of the audio interface. He also said that you can set up QoS in Windows “somewhere in the network settings” (which turned out to be completely erroneous) without giving an ounce of help or direction.

Towards the end of our call, he was just trying to get me off the phone basically with an answer of “you’re fucked” to all my questions. At that point, I got pissed off and demanded to speak to somebody else. Finally, I got put on the phone with one of their product engineers and they actually addressed my issues. Long story short, the engineer ended up having to do a remote support session and did indeed acknowledge my AGC issue and gave me an explanation of why I couldn’t see the QoS settings mentioned in the manual. It turns out, those settings only show up if you use their provisioning server and they don’t even set the QoS settings in Windows like I needed.

Polycom RealPresence Desktop – Do Not Minimize to Taskbar Tray

While poking through the registry trying to find a way disable Automatic Gain Control (AGC) for Polycom RealPresence Desktop (version 3.3.0.50871) video conferencing software, I stumbled upon a different registry key that addresses another annoying problem and that is to keep RPD from minimizing itself to the taskbar. Low and behold, it doesn’t appear that there is a setting associated with this registry key inside the program to disable this functionality either.

As a side note, I did have to open a support request with Polycom over the AGC issue as it automatically takes over the audio recording interface even after disabling all of Windows control over the settings and it negatively impacts conference quality. Because the software automatically dials down the input level of the recording interface, the user then has to yell just to be heard, which only further possibly causes the input level to go down even more, without ever adjusting the audio level back up. Currently, there is no way to turn this off, so it will probably end up as a feature request for the next software release.

Server 2012 – Restrict Access to Specific Drives via Group Policy

If you’re familiar with Group Policy, there’s been an administrative template available since the Windows 2000 days to restrict access to the drives in File Explorer. The only problem with that template is that it only gives you the options to remove access to either all the drives or drives A, B, C, and D which is isn’t very flexible.

In search of a more granular option, I found this very helpful post here that explains exactly how to restrict access to specific drives using registry keys. Here I’m just going to copy the table and show you how to add a Group Policy Registry Preference to achieve the same thing.

Server 2012 – Remove Network Icon from File Explorer Navigation Pane via Group Policy

After much research, some poking around in the registry, and a little dumb luck, I’ve discovered a way to disable the Network icon from the left side of the File Explorer navigation pane on a PER USER basis using Group Policy Registry Preferences.

Basically, I borrowed the concept from other posts and made it work for the current user profile. One problem that I ran into trying to use the HKLM key was that I couldn’t update the key using the SYSTEM account via Group Policy and I didn’t want to manually edit registry permissions on a bunch of RDS Servers. On top of that, more importantly, I didn’t want to disable the Network icon for my administrator accounts too! So here’s what you need to do… Continue reading “Server 2012 – Remove Network Icon from File Explorer Navigation Pane via Group Policy”

Classic Shell – Registry Entries for Custom Windows 7 Style Start Menu

When applying the Classic Shell Group Policy Templates in Windows 2012 RDS, there is an option called “Menu items for the Windows 7 Style”. In order to customize the menu items, you first need to make changes to some user profile that is using Classic Shell and then go and retrieve the entries from the HKCU\Software\IvoSoft\ClassicStartMenu\Settings\MenuItems7 key in the Registry to know what to enter there. Even on the Classic Shell forums, they didn’t have it documented so here goes…

First, you should have a list of entries titled “Items(1-23).Command=” followed by the friendly name of the item.

Item1.Command=user_files

Following each one of those entires, you may or may not have an additional entry for each item titled “Items(1-23).Settings=” followed by one or more of the display options depending on how you want it displayed.

Item1.Settings=NOEXPAND

As of Classic Shell version 4.1, here is a list of the Command names and their descriptions:

admin - %AppData%\Microsoft\Windows\Start Menu\Programs\Administrative Tools

Batch Script – RDS Start Menu Application and Taskbar Shortcut Removal Tool

Customizing or locking down a new server for Remote Desktop Services in a Server 2012 environment can be quite a time consuming and daunting task. Countless hours will be spent setting up Group Policies, testing them, and deploying them. But far worse than that, you will waste massive amounts of time researching for jacked up ways to do simple things, such as unpinning items from the Taskbar and customizing the Start Screen.

In the past, I had already configured a company wide Group Policy for our old 2003 Terminal Server environment and it was simple and easy. No guesswork, no crazy workarounds, shit just worked. The Group Policies covered almost every scenario or task needed to lock down a server but unfortunately, that is not the case any more.

It seems Microsoft has made the process of doing pretty much anything ridiculous and overcomplicated. As a side rant, we (the world) desperetely need a good open source solution for a thin client type environment with something that mimicks Group Policy. I know I’m not the only person out there that would love to give Microsoft the old stink finger once and for all! I for one am tired of sitting and watching companies succumb to the endless money pit that is Microsoft licensing. Where you at Linux Devs?

Anyhow, I decided to write this script for a lot of shortcomings I’ve encountered along the way. One of which that I want to gripe about is that resorting to changing file permissions to remove shortcuts is just plain fucking retarded and redirecting all of the user’s start menus to a network share seemed like massive overkill to an already complicated scenario. On top of that, I had 6 separate Remote Desktop servers to fully setup and configure so I needed to streamline the process a bit. Suprisingly enough, my solution relies solely on batch scripting (and a little makeshift VB).

Enough chit chat, the script is extremely well documented so here are the highlights/features:

  • Removal of the Server Manager and PowerShell links in the Taskbar
  • Ability to backup the All User’s and Default User’s Programs directories to a zip file
  • Ability to copy the All Programs Start Menu shortcuts to a list of administrator or power user profile directories
  • Customized list of applications to remove from the Classic Shell Start Menu or the Windows Start Screen
  • Deleted Start Menu Program entries go into the active user’s Recycle Bin and can be restored if necessary
  • Remove System Tools, Accessories, Accessibility, Administrative Tools, Windows Store, PC Settings, Control Panel, Run, Command Prompt, and PowerShell shortcuts from Menus

:: RDS SERVER 2012 CUSTOM START MENU AND TASKBAR SHORTCUT REMOVAL
:: Author: Nathan Thomas
:: Date: 02/11/2015
::
:: This script should be ran on the RDS server after your server administrators have already
:: logged in at least once so that they get all the shortcuts they need (otherwise you will 
:: need to manually copy them later on) but before your end users log in for the first time.
:: In addition, it assumes you have not already made changes or any customizations to the
:: All User's or Default User's Start Menus profiles and that you have already installed all
:: of the applications that the server will be running. Please note that if you decide
:: to install software after you've ran the script, you will manually have to remove that
:: program from the All User's Start Menu folder and copy it to your administrator profiles

Batch Script – Sending Items to the Recycle Bin Without Calling Any Third-Party Applications

While writing another larger script, I wanted the ability to send folders or files to the Recycle Bin, which I found out you can’t do natively via the command line without using some third-party apps or PowerShell.

I also found that when looping through a list of files in a batch script, it makes it really difficult to delete folders versus files because you have to either use the “del” command for files or the “rmdir” command for folders. With no simple way to differentiate between the two without a bunch of extra code, I kept looking for an alternative solution.

Batch Script – Zip/Compress Files Without Calling Any Third-Party Applications

While writing another batch script the last several days, I found out that you cannot zip or compress files or folders natively from the command line without having additional third-party software or PowerShell. After a while of scouring the forums, I came up with this pure batch solution that uses VB script.

Basically, from this chunk of code in a single batch file, we can both generate the VB script, zip up whatever files we want, and then just delete the VB script when we’re done. Within the batch file, we can just call on the VB script using “CScript” and it works pretty much like any other function in any other programming language.

Batch Script – Get User’s SID One-Liner

While researching a way to try and send files to a user’s Recycle Bin from a batch script, I came across this one liner either at StackExchange or SuperUser forums somewhere. FYI, there is no way natively to send something to the trash without using a VB script or some third party utility. Yes you can physically move the files into the C:\$Recycle.Bin\<UsersSID> folder, but the files will not show up in Explorer and won’t be removed when you empty the trash that way.
