Internet Explorer Cannot Download a File on Server 2012 R2

So you have just set up a new Server 2012 (R2) server, and gone to download that fine you need for the next step, only to be shown a nasty message stating that you cannot do that, as file downloads have been disabled.

NoFileDownload

Well the good thing to know is that its an easy fix, simply open up “Internet Options” go to the “Security” tab, select the “Internet” zone and Select the “Custom level…” button

InternetOptions-SecurityTab-CustomLevel

This opens up a “Security Settings – Internet Zone” window. In the main section of the windows scroll down to where it says “Downloads”, and the the subsection of “File download” (as of this writing the setting is just above half way down the options list) and simply change it from “Disableto “Enable”. Click ok and drop back to the main screen and retry that download again

EnableDownloads

If you get a warning, as shown below, simply OK it and continue on

Have fun

EMCO Remote Shutdown

Remote Shutdown from EMCO Software is a great piece of software for helping to manage fleets of Windows Based PC’s in large environments, it uses Wake on LAN to start PC’s up at a certain time, certainly nothing fancy with that, however what else it can do is force log offs and shutdowns on a schedule as well. It does this through some clever use of facilities already built into Windows, but little used. I would certainly rate this software highly and recommend its use to anyone with large fleets to manage.

I have used it at several clients to manage their fleets to start up the PC’s before workers get there, and to shut them down after they leave, this is to stop people leaving them on from sheer forgetfulness (if it needs to be left on we can exclude the PC from shutdown for the required time, but people do need to tell us) and we use it as part of our environmental program to minimize power wastage. People if logged in and using the PC at the time the shutdown or log off instructions come in, can cancel it themselves (we do not want to stop people working now do we).

This has helped with several things, as we have a specified lunch period at each site, I shut down the PC’s 10 minutes after it has started, this is to allow updates to install, and restart the PC’s 5 minutes before people are due back at work. We have a much greater patch ratio now, than before this happened. The schedules at the sites are simply, start at 0800, shutdown at 1345, restart at 1455, shutdown some PC’s at 1610PM, shutdown all PC’s at 2000.

In addition to this when one of the clients had an environmental audit (they were chasing a 6 star environmental rating) the auditor was impressed with the technology and it aided in their gaining of their 6 star rating

All in all I am very impressed with the EMCO solution and highly recommend it

Internet Explorer & Other Multi-Tab Group Policy Settings

So visiting a client today and I noticed that the group policy settings for Internet Explorer were not applying correctly, some settings were aplying, some not. After looking at the settings and the RSoP, I decided to take a look at the XML generated for the GPO, and that’s when I saw it… disabled=1, hello. Now the question is where did it come from, I know the GPO is working in other respects, and checking the XML confirms this, so I re-generate the settings, 5 minutes work but still no resolution, its still stating that it is disabled.

What is a IT professional to do, woe is me… Looking further into the situation I came across something I had long forgotten, and filed under “I will never need that”. What was happening or rather not happening was  I was not enabling the fields, specifically in a multi-tabbed setting you will see a red dashed line or a red “No” symbol (the same red border and line that you see everywhere something is prohibited, no smoking sign for example). As shown below

stopped symbol   Dashed Line

To enable the settings you need to hit one or more keys depending on how you want to do it, these keys are as outlined below

F5 – Enable all items on the Page/Tab
F6 – Enable Currently Selected item on Page/Tab
F7 – Disable Currently Selected item on Page/Tab
F8 – Disable all items on the Page/Tab

Once you have enabled the items you will get either a solid green line or a green OK symbol as shown below

green line  go symbol

 Once this was done, I simply forced an update of group policy, and viola, everything worked as it should once more

Moral of this story, its the things you think you don’t need, that ultimately you will need

SafeDuino – Part 05: First Released Part Sketches

Further to my last post on the subject I have had a little time, or rather made a little time and created two boards for use in the movement of power and data from the EtherMega to where it’s needed. The first is a RJ12 connection so 4 data pins are possible, the second is a RJ45 connection so 6 possible data connections.

Both boards are double-sided, and have multiple power inputs/outputs and are designed in such a way as to be stackable either vertically, horizontally or both to allow a layer cake effect for these connections, there is a row of single header pins at the “back” for the board and you can mount either horizontal or vertical pins in it, or as I intend to do, pins at an approximately 45 degree angle, but we will see how that works.

As the boards use standard header pins for all instances it is possible to integrate them into your own circuits, however where possible I would recommend integrating the RJ12/RJ45 part directly just to eliminate un-neccicary connections and components.

Anyway eithout futher adu;

SafeDuino – Part 04: Further Afield – A Complete Redesign?

After having not had much time to work on this project in the past few months, with a major half-million dollar project going on at one of my clients, which was/is the implantation of a new computer system of my own design that will be serving them for the next 20 years or more (well the physical infrastructure will be, the PC’s wireless, network, servers etc won’t they are replaced on a 3 year cycle, again on my insistence) and with one of the suppliers delivering critical components in excess of week late it has pushed back the final deployment for a couple of months as now I can only do core works on weekends and after hours, I have not had much time for this project.

What I have been doing/contemplating is two things however, firstly is whether I need an LCD screen/buttons interface, and I have decided that I do need one, this has become evident so that I can set up the system “in place” when it is finally deployed.

The other thing I want to do is be able to deploy some sensors and control circuits remotely, including some in hard to access places, well ones that once they are in they will not be easily accessible. To this end I have come up with the idea of using network cable for limited power (5VDC for system power) and command and control signals, and where required I will use Flat-Flex Cables’ (FFC’s)  to get into those tight spots that I cannot otherwise support sensors in. 

 What this leaves me with is a system that is essentially divided into three distinct parts, the main controller (the Freeduino EtherMega) the distribution node which is connected to the EtherMega via network cable, and the sensors and control points are connected to the distribution nodes via CAT3 (telephone) cabling or via FFC’s (which are limited to 18″) where required.

This now leaves me of working out how to select which pins go to which distribution point via the network cabling, this I am still trying to solve, however jumper wires are looking like the best option at this point

SafeDuino – Part 03: The goalposts change

Ok, I admit it… feature creep has officially set in on this project.

After doing the basic designs and working out I needed the EtherMega (from Freetronics) for the SafeDuino project, and consequently purchased some (I say some as I keep changing the design) of the components I decided that it was a “waste” of a mega to only use the small number of I/O’s I needed (but more than I could get from an ethernet connected UNO), and this is where the feature creep began.

So, now what I have is more of an environmental monitor not only for the cabinet it was to maintain originally, but also for the room/building it is housed in, this will allow me to do differential monitoring for parts of the building vs the areas I am going to monitor/control individually.

So far I have determined, that beyond the original cabinet it was going to monitor, the following are going to be monitored;

  • The building itself, this is to allow for differential comparisons and fluctuations in temperature and humidity to see if the things I am putting in place to control humidity are in fact working
  • Two other cabinets, including one humidor, just because I can 😀
    • Turn on/off humidification/dehumidification equipment and fans to allow for circulation in the closed environments based upon readings
  • Possibility of wine/beer fridges
  • External temperature/humidity
  • Solar Radiation (for estimating solar panel power generation)
  • Background radiation, this is more of another because I can thing, being able to monitor radiation (Alpha, Beta, Gamma) in the background of the environment long-term will be useful in the future just to see the changes over time, I will be connecting it to one of the sensor networks that have popped up after the Fukushima accident
  • Internal and External light sensors, again to see how it affects temperature/humidity in the closed environments/building
  • Same goes for door/window openings

I am sure there is more to come, in fact I know there is, I have 40 odd pins to fill up :D.

In addition to these added features, I have decided to add some protection to the arduino itself through the use of optocouplers/optoisolators to isolate the external electronics from the device itself, where possible anyway, this will also take some of the current loading of the arduino board. So far I have confirmed that the 4N25 optocouplers work, and I have tested those which I have purchased to ensure they operate correctly.

I am still to get a few linear optocouplers for use the with the voltage divider to allow me to monitor the voltage in the battery system.

Considering ultimately that the EtherMega will be powered via POE (supplied by the switch, so a proper 801.11af regulator, which is being done to ensure monitoring will continue even if the batteries for the lights etc fail) there will be no load on the batteries apart from a few mA for sensors and alike for the most part, but I will be configuring the reed switches for example to be Normally Open (NO) so that there is no power going through them when they are not activated (apart from what is used by the resistors to keep a proper ground) I should be able to maintain this for a long period with just the batteries, and with a solar charger, I should be able to maintain this use of the system indefinitely.
