Remote Safe Mode Reboot With VNC


This article will show you how to remotely reboot your networked Windows computers into safe mode using Bozteck VENM Remote Desktop Manager with the ability to remote control them while in safemode using VNC. 

As Systems Administrators, most of us have found ourselves walking into work on a Monday morning with users reporting a widespread malware outbreak.  This typically means physically visiting each PC, placing them into safe mode, then surgically removing whatever malware had infected their systems.

Bozteck VENM makes that tedious task a little easier on you by allowing you to reboot those computers into safemode from your own desktop and giving you remote control ability to the affected computers using VNC. 


  • Bozteck VENM 2015.11.25 or later
  • An account with Administrator access to the remote machines
  • Firewall must permit:
    • TCP 5900 – VNC
    • TCP 139  – Windows File Sharing
    • TCP 445 – Windows File Sharing
    • UDP 137 – Windows File Sharing
    • UDP 138 – Windows File Sharing

Background DNS Updates for VENM Console


Starting with version 2014.3.30, VNCScan will automatically crawl your groups and update the DNS to IP resolution for each computer.  In this process, it will also ping the new IP address to ensue that it is alive.  If it is alive, it will update the “Last Up” field in the list for that computer.

Starting with version 2014.4.6 released today, you can disable this functionality from the main program preferences.  You may wish to do so if you are not populating the Host Name field with true host names and only connecting to the computers by a manual IP address entry. 

We have also heard of problems with the background DNS updates if you are using Open DNS on your network and have NX Domain Redirection turned on.  We recommend that you disable this feature in Open DNS because it can cause other problems with other programs also but if you need to have it enabled, you will want to disable the background DNS updates in VNCScan

You can disable them from this screen in the main program preferences,



In addition to this new feature, VNCScan will also now perform daily backups of your VNCScan database file to the Data folder where the vncscan.mdb resides using the format.

What’s In Your Lab?


I am a strong believer that every IT Professional should have a personal lab environment where we test and learn about every possible scenario before we experience or deploy it in the real world.  Mine is a bit more elaborate than most people probably have in their home but if you are in this industry for the right reasons, you want the best that you can cobble together.


My lab is running Hyper-V 2012 r2 on a Dell R710 with dual XEON processors and 180GB of RAM.  I have two Synology iSCSI storage units attached through a Cisco gigabit switch with a VLAN for storage and another for the VM network.  While I do have a functional SCVMM 2012r2 server running on the network, I prefer to do my staging the “old skool” way – Copy a VHDX to the the “Virtual Disks” folder on the server, rename it, then create a new VM using that disk. 

I use my lab to test scenarios for upcoming deployments, to explore different ways that things break, or to debug software issues in my Bozteck VNCScan product.  It’s safe to say that something on the lab changes daily and that I am often in it more than I am in the live environments that I manage. 

To every budding new IT Professional who asks me for industry tips, this is always the first one that I passionately offer.  Build a lab.  Live in that lab.  Before you deploy anything in the real world, you should have already had at least a couple of run-throughs in your lab environment.

Starting Over …

My old blog was cluttered with a mixture of personal opinions, product reviews, and just plain rambling.  I would like to strictly focus this new blog upon the type of technology related topics that we like to cover in our IT Unwrapped podcast.

I have had a long gratifying career as an IT Professional and I never stop learning new things.  The Technology field is truly a career path where you can never get comfortable for very long with your current knowledge and skill set.  There is always something new to learn and an emerging technology to keep up on.  These changes and learning experiences are what I hope to bring to the reader of this blog.

I have an enduring hunger to learn and experience every aspect of technology.  I drive the non-techies around me crazy because I just live in this world where not many “normal” people can relate to.  I am sure that anyone who will come back time and again to read the posts here will understand that scenario intimately.

So, here we are with the opening blog entry with many more to come.
