I need to add reserver IPs for a few network devices on our network.
In the juniper router it there is a section to reserve IP's. But if I check the reserve button and add the ip address with the mac address and click on OK. Will it disable DHCP?

Im going to attach a screenshot of the Page Where you reserve IP'sPage where you set reserved IP's

Experts, please advise!

We need to install WES7 (Windows Embedded Standard 7) for a POS environment on an HP Thin Client.

We have four HP Thin Client t520 models, pre-loaded with the HP Thin Pro operating system.

We have just been informed by our third party POS support that we will need WES7 for other hard/software compatibility purposes.

Thus, the device does not have WES7 pre-loaded.

Now, we need to backtrack and get these units loaded with WES7 -- which is proving to be a hurdle.

I've downloaded a trial version of WES7 x86 (matching the hardware specs for the Thin Client) and am encountering an error regarding drivers needed to begin the installation process. We are able to boot the .iso and get to the standard Windows installation page but soon encounter an error regarding drivers. There's no specification of which driver is prohibiting the install from proceeding.

Is it possible to install WES7 on an HP Thin Client hardware. As you can tell, we are new to this "Thin Client" environment and hardware. Microsoft doesn't clearly answer how to get this WES7 onto said devices without ordering WES7 pre-loaded/OEM.

Thank you.

How can I reset a Dell R610 BIOS back to its default settings?

I have gone into the BIOS but so far haven't seen any options on how to do this.

How can this be done?

A customer has started having a recent issue with his Dell PowerEdge R610 server.

While the server is running the POST is displays the messages shown in the screenshot about several DIMMs being disabled.

This server used to have 24 GB of RAM and now only 8 GB of RAM is recognized within the Server 2012 R2 OS.

I have gone into the BIOS and haven't yet been able to find a way of setting the BIOS back to its default settings.

I have also looked at the RAM and other configurations within the BIOS and haven't yet been able to find any settings or configurations that look like they could change these settings.

This server is already running the latest BIOS version and when the Dell update is run all other updates have also been installed.

This issue started occurring around 2 weeks ago and since then the customer has tried to fix this issue by updating the BIOS to the most current version which hasn't fixed this issue.

This server is out of warranty otherwise I would call Dell.

What can be done to fix this issue so that the full 24GB of RAM will once again be recognized by this server?

Greetings,

I have a few Symbol MC92N0 devices running Windows Embedded 6.5.  Is it possible to join them to a domain?  If so, instructions would be appreciated.  It looks like I need MDM 2008SP1 (and with it Microsoft System Center).  Is that correct?

My goal is to get a computer and user certificate on the devices so they can communicate over my WPA2-Enterprise wireless network, which requires both.  I have almost no experience with Windows Embedded.  Any pointers appreciated.

I'm tired of half-stepping my office server. I suppose you could consider what I do with the hardware a hobby but I also run my business out of my home and it  very much relies  on the VMs and data stored within.
I tried to upgrade my host without doing my diligence with the research. Now I'm paying for it and everything is running in limp-mode on the backup server (at least I have one of those) until I get t he new board.

My wife is going to make the new board my Christmas gift so as soon I complete this post I'm going to box all of this up, send it back and pace the floors until that day. Very exciting stuff!!!!
Phillip suggested a couple of boards and that may very well be the one to go with but I would like to give you experts more detail about the environment so that we know we are getting the correct board for the job.

 So here is the criteria I would like to see on it:
The existing board is ATX but I can see studs in rack-mount case for larger

Real raid onboard with bbu

Dual processor and maybe (but probably not) LGA1150 slots. I have this new  (1) Xeon 3.4.
If LGA1150 not a good option then we can just get 2 new processors

Lots of DDR3. The existing server has 32G of server memory

Gigabit NICs. 10 Gb/s would not do me any good beyond my switch anyway.

Also the existing case has a cheap backplane with individual SATA and Molex connectors for the power.

Hi,

I found some rams in my old box. Are those ddr3?

In order to use Sense Hat https://www.raspberrypi.org/products/sense-hat/ under Python 3, I tried to run "sudo pip-3.2 install pillow" because that was what I was told when I tried to run "sudo apt-get install sense-hat" (http://pythonhosted.org/sense-hat/). However, below error happened. Does any one know how to solve this problem? Thanks!

...If I2C was disabled prior to this installation, a reboot is required.
To work under Python 3, the Sense HAT library requires pillow.
This can be installed by running 'sudo pip-3.2 install pillow'.

I'm tinkering with the idea of developing in Java for an embedded system.

The system has a somewhat primitive LCD screen, with black and white pixels, 180x160 pixels.

How does one interface Java with a specific hardware screen?

What sort of "screen" class would I make, so I can interface this with Java?

Are there any examples?

(and then of course I'll also made an LCD screen emulator class which somehow displays on a regular computer screen.)

I am having an issue with an HP Pavilion 20-3013w all-in-one pc.   The hard drive went bad and I can't get it to recognise the replacement.   It keeps saying Error: no boot disk detected or drive failure  The original drive was a 500gig and the new drive is a 2TB drive.   The 2TB drive is brand new out of the box.  In order to get by the message that is displayed I have to move some jumpers on the system board to clear the bios.   Once the bios is cleared it will let me press ESC or F10 to get into the bios screen to disable secure boot.

Any suggestions?

Thanks.

In Outlook 2013 when I reply to an email that has come in as text only my signature line shows up as text only on my reply. It basically disables the links for email address and website address on my signature . How can i make it so no matter what the source email is formatted as that my signature line links will always be active?

Thanks

I just bought a new GUSTT brand wallet (on Amazon) which blocks RFID. I have a few new credit cards which have the chip in them and had high hopes.

So I was excited to test it out since I have an MBTA Charlie Card and fully expected the wireless access to fail as I waved the wallet in front of the receiver. But the gate opened, like it used to with my leather wallet. So is this a valid test? Should the Charlie Card's signal have been blocked. Here's the technology used in the Charlie Card.

Does this mean it's a "wallet failure"?

I am rather bummed (pun intended).

Thanks.
