CryptoWall 3.0 Ransomware – Ouch, It Hurts So Good…Get Out the Backup Tapes. You’ve Got Those Right?

Being the badass network admin that you are, you try to keep your servers up to date with all the latest Windows updates, you run antivirus on all your machines on your network and scan daily, you have made sure that none of your users have local admin rights to their machines so they can’t install any software, and so you think you are fairly well covered when it comes to viruses and spyware, well think again.

My company just got hit pretty hard with this new CryptoWall 3.0 virus. If you are unfamiliar with it, basically it encrypts any user accessible data on local and network shares that it has permissions to and holds it ransom for BitCoin payments.

VMware vSphere Client – Remove Cached Entries on Connection Screen

For a long time, I’ve just dealt with having a massively long list of old VM servers in my vSphere client but today I finally decided to take a minute to do something about it as it was just getting too ridiculous to navigate to find the servers I wanted to use. A quick scour of the web led me to the following registry key, all you need to do is edit the comma separated list, delete out the entries you no longer want, and be on your merry way.

HKCU\Software\VMware\VMware Infrastructure Client\Preferences\RecentConnections

Server 2012/Windows 8 – Complete File Explorer Icon/Shortcut/Folder Removal List

I thought I would share with you the master icon removal list for File Explorer that I’ve compiled from various sites. All of the articles I’ve come across tend to delete the icons for all user’s, but I’ve found that it is possible to delete some of them on a per user basis by creating the key structure in the HKCU section of the registry instead. You’ll just have to fiddle around with them if you want to try it.

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{CLSID}\ShellFolder

My biggest bitch by far about Server 2012 is that it doesn’t appear to even be a finished product in regards to Group Policy lockdown procedures. On almost every account, you have to hack the damn registry to get rid of unwanted items from File Explorer not to mention the god damned Ribbon UI which I’m going to do a whole nother post to rant and rave about and explain how to customize/remove icons from it. I’m not going to go into great detail here on how to add them through Group Policy Preferences or anything so if you need to know how to do that, check out some of my other articles where I explain how to do it.

Server 2012 – Set Proxy Server and Prevent Changes via Group Policy

Thanks to Microsoft, with the removal of the Internet Explorer Maintenance section in Group Policy since IE9, once again they’ve decided to make things more complicated and the end users have lost yet another important administrative tool required for many environments.

That being said, the only way to set and enforce proxy settings in Internet Explorer now requires hacking the registry, which I’m seeing as a disturbingly all too common trend when setting up an RDS server. Here are the keys to the kingdom:

User Configuration > Preferences > Windows Settings > Registry

UltraVNC – Password Not Set: How to Install as a System Service

Trying to get UltraVNC (version 1.2.0.5) to run as a system service is a pain in the ass if you don’t follow a specific set of steps during the setup process. It appears that if you check the box to install it as a service during the initial installation wizard, you will encounter the annoying “Password Not Set” error and nothing works. I also had issues with running the MSI installer rather than the EXE, so stick with the executable if you’re in a rush. I don’t have time at the moment to write up a giant all-encompassing post with accompanying pictures and what have you so here’s what you gotta’ to do:

Server 2012 – Creating Always Maximized Internet Explorer Desktop Shortcuts to Websites via Group Policy

One annoying thing that happens a lot in Windows is the odd window size in Internet Explorer when clicking on any URL type shortcut icon. Unfortunately, with the URL type shortcuts, there’s not really a way to guarantee how the window size will be positioned every time as most of the time it goes by your previous IE window’s state but we all know there are scenarios where that isn’t always the case.

Server 2012 – Set Internet Explorer Home/Start Page via Group Policy

If you want to set the user’s home page initially but then allow them to change it to whatever they want, on the Common tab in Group Policy Preferences, just make sure to check the box “Apply once and do not reapply” otherwise, any changes the user makes to their home page will be lost the next time they log in.

Server 2012 – Add a 32 Bit Internet Explorer Shortcut Icon on the Desktop via Group Policy

On an 2012 RDS Server, when running a software restriction policy, your 64 bit browser won’t work unless you specifically create a rule to allow it. In addition to that, on an RDS Server, there’s not really any advantage to using the 64 bit version of IE because almost all plugins were only built with 32 bit support.

That being said, at first I had some trouble creating a desktop icon for the 32 bit version of IE using Group Policy Prefences. Strangely enough, if I set the path in my shortcut to %PROGRAMFILES(x86)% it still brought up the 64 bit version of IE somehow, WTF?! Basically to figure this out, I just copied the shortcut properties of the IE icon on the Classic Shell Start Menu.

Foxit Reader 7.0 – Set as the Default PDF Viewer via Group Policy

When locking down your RDS Server, here are the registry keys needed to set Foxit Reader as the default PDF viewer per user via Group Policy Preferences to disable the annoying first run pop-up (technically, you can use just the last registry entry only and it will work but adding all of the keys is probably the safer approach):
