10GB network not performing as expected.

Hi, I am looking for help as to how I can effectively test that my 10GB network is giving me 10GB

I have a blade chassis with 2x M8024-K 10GB switches installed.

I then have BCM57810 10GB adapters in each blade. The backplane on my chassis is 1.1 which is for 10GB support.

When I run tamosoft between the 2 blades I get around 1850Mbps down and 1150Mbps up. Running the same test on a 1GB connection on the blades I get 617Mbps down and 462Mbps up.

So the 1GB network seems to give what I would expect, whereas the 10GB (20GB effectively) is only running at 20% or 10% if you take the team into consideration.

I have updated all firmware and hardware on both the blades and switches.

I thought maybe TamoSoft isn't designed to test 10GB effectively, so I set up Iperf3

have put iperf3 on both machines and I am running iperf3 -s on the server and iperf3 - c xxx.xxx.xxx.xxx -w 1020k -P 4 and its returning the results below, I tweaked the amount of streams and the window size, these seem to be the best results I could get. Is this what I should expect or should I be able to get more? The connection I am testing in theory should be 20GB as its 2x10GB in a team.

Cannot get desktop to boot.

Dell computer will not boot. I have run the F-12 diagnostics and when it hit about 45% of hard drive test it stopped with this error. 0f00:133c No suitable media present. I have tried to run in safe mode, pulled off all hardware but monitor, mouse and keyboard. Still will not boot. I have restore points going back to the start and none work. It seems the hard drive is bad. I need to or hoped to pull the documents off and just re-image but when I sled this to my other laptop, it sees the drive but says no media present? Any way to pull the data or know for sure it is the hard drive? I have run and exhausted all testing that I am aware of.

This is to find out about 100+ Windows Servers in our production. All these servers were joined Windows AD domain. We wanted to know on each individual server, what is the Windows Server version installed, CPU core and some other hardware information.

Do we need to have the administrative privileges? How about if we don't have the privilege? Would powershell manage to do the job?

Thanks in advance.

Refurbished cell phone

I need a new battery for my Samsung S6 Active and it is going to cost me $70 dollars plus postage to send it into Samsung for repair because it has the water seal and none of the local repair centers will touch it. I am thinking of getting a Samsung S7 Active because I don’t think the S8 is worth the price. I am thinking of getting a Refurbished which I have found for $245 or a new one for $474 both unlocked. I can get a one year warranty on Refurbished one for $54. Anyone had any experience with Refurbished cell phones? Do you think it is worth the extra $230 for a new phone?

Hi Experts,

I'm going to do a site visit to one of my clients this Friday afternoon to troubleshoot speed issues (mostly Internet-related) on a recently purchased and installed Windows 10 Pro box, as well as a Windows 7 Pro box. I've checked them both remotely and have been unable to resolve the issues.

I *think* the problem with the Windows 10 box is DNS related, but the only difference between it and the rest of the office machines, is that DNS settings are obtained automatically by the Windows 10 machine, while the rest of the office workstations have been configured with static IP and DNS settings (by me) some time ago.

I tried changing the DNS configuration to static settings remotely and ended up being booted out with the machine no longer able to connect to the Internet, then had the embarrassment of having to talk one of the employees through changing them back to automatic, so a site visit is now inevitable.

Both are hard-wired to the network with CAT6 cabling, both have SSD drives and ample RAM. The Windows 7 box is identical to more than a dozen other workstations in the office.

Anyone struck this before when Automatic IP configurations are being used to connect to a server, vs static IPs?

The office recently underwent an entire rewire from CAT5 to CAT6E and all Routers and Switches are GB in speed. I intend to check the cabling for both machines, but I doubt that will be the problem.

What else would you recommend checking into with such a …

Can anyone advise why an old IDE internal hard drive (Seagate ST380020A) won't mount on Windows 10 using an USB enclosure?

Thinking it might be the jumper settings, page 25 here: https://www.seagate.com/files/support/disc/manuals/ata/u6pmrevb.pdf

Currently no jumper (slave setting) and it just crashes Windows file explorer.

Any help much appreciated.

Video Capture connections

I want to capture old video and have the hardware and software to do it. However I cant get it to work.
The capture device consists of four cables and USB connector. The four cables: , one yellow (marked video) , one white (audio left), one red (audio right) and a fourth cable with a black circular female input (marked S-Video) . I am able to attach the red, yellow and white connections to my VCR without any difficulty. However the VCR socket (S-Video) for the fourth cable is female. So I am unable to attach the Video capture cable which is also female.
My question, does that fourth cable have to be attached to make it work. If so can I get an adapter. I ATTACH TWO PHOTOS TO EXPLAIN

i have a DELL XPS 8700 desktop and have a decent video card in it now. I have upgraded it to 32GB RAM and it has been a great computer. I love this desktop and I am running windows 10 pro with all the latest updates installed. I have 2 new monitors that use what they call Thunderbolt 3, this port looks like a USB -C port. The monitors work great on the macbook pro, and the other Dell XPS laptops that have a TB3 port.

However, I am wanting to buy a video card that will support these monitors with a TB3 cable (LG Monitor). I don't do anything like gaming, mostly just word documents, visual studio and visual studio code. Is there a video card I can buy and install that will give me a TB3 port for the new LG monitors?

Thanks in advance

Connecting my WiFi Xerox 6022 Laser Jet (Macbook)

My printer stopped working, and before I realized the router was blinking, I deleted the Printer.

Now I have reconnected it with the WPS button, but I can not find how to add the printer to my MacBook, so I can use it.

What am I missing?

I need to help someone get a laptop. The ones I am looking at have a small SSD and a much larger HDD. How can I configure the system so the user isn’t filling up the SSD with data or programs? Is there anyway to force everything except the OS to go to the HDD with little or no user interaction?

Security Badge (HID) Card won't work

Security Badge (HID) Card won't work. We are having an unusual issue with HID enable security card. We have been using a fob (dongle) for many years and we are now changing it to the card that we print pictures on it. With the new card, it works after activated but it won't respond after two or times of time! It acted as the card is not there. it is not like the card has wrong permission. The card simply won't do anything. no beep no led indicate. We thought the printer that prints the pictures on the card, but it wasn't. it worked before print it and after print it. What could that be?

I just bought an Acer netbook/tablet, and it is a dandy computer.

HOWEVER, whenever I turn it on, up pops an "End of Service" Notification, informing me that Acer Portal Services will be discontinued on 2018/09/30. I am writing this on 2018/10/11.

I click on the link on the Acer service page " For more information, please check our FAQ" and it takes me to a mostly blank page except for the short column in Japanese. Or Chinese. Or Whatever.

The online support seems to be filled with stuff dating as far back as 2002 and nothing seems applicable to this situation.

Customer service by phone didn't work because the service agent's accent made her words pretty much incomprehensible (and I have a degree in speech, which usually comes in very handy in situations like this; not so here!) After waiting an excessively long time to be transferred to another agent, I gave up and hung up.

I'm not a super-tech guy, so I'm hesitant about going into directories and deleting files that give the impression they MIGHT be related.

SO, experts,,,,,anybody know how to remove this already expired worthless notice?

Great tip for Surface Pro users Brandon, thanks for sharing it.

I often leave my (now old) iPad2 plugged in 24/7 next to my bed because I use it to listen to Audio Books that I buy from Audible and think something like that would be a top idea for that too. I'm surprised that IOS and Android developers haven't thought of including a feature like that for their devices. Wonder where I could make such a suggestion? Would make the various battery saving apps available all but obsolete.
