• HP Pavilion 500 series: customers

  I had a 500-300 t HP desktop computer and it was a lemon so I now have an HP Desktop 500qe.  Well, if you want a descent computer please do not buy a 500 series.  I've always bought HP products.  Printers and all make Hewlette Packard.  They are so slow and freeze shut down and all.  I would never buy another HP unless I came across a computer 5 stars for a 3 star price

  Thanks but no thanks. I am done with HP and do not want to deal with the issue more.

• Pavilion 500 series: printer does not complete the print job & error message

  Got a HP Deskjet 2542, but recently bought a new HP, Pavilion of the 500 series desktop computer.  When you try to print a document that is located at 3 pages, it will print the first page, and then part of the second page, then an error message appears.  Went to the HP troubleshooting & tried everything, but nothing seems to fix the situation.  Any ideas or suggestions?

  Hi @Themommy,

  I saw your post about the error message that appears when printing with your HP Deskjet 2542.

  I need a little more information to give you the best course of action.

  What is you receive the exact error message?

  Without this error message, I suggest trying a free tool called HP Print and Scan doctor to diagnose and troubleshoot printing problems. I recommend you to download and run the HP print and Scan Doctor, if she doesn't fix it automatically let me know what errors or messages that you receive.

  You can always try to uninstall the printer software and then by downloading new firmware for you printer. Click on this link to get the all-in-one HP Deskjet 2540 Printer series full feature software and drivers.

  Just note that you may not be able to download the software right now. If you click on the link above and you get this pop-up window, you may need to try the page later.

  

  Please let me know if these steps solved your problem, or you receive the exact error message.

  I look forward to hear from you!

  Thank you

• Proxy Web on ISA 500

  Hi all

  This may seem like a basic question, but I'm looking to set up the external "Web Proxy" feature in ISA 500. My main question is this web proxy can be an internal proxy which is the use of the word "external" refer to area WAN or it refers to 'external' to the device?

  Thank you

  Eoghan

  It refers to a Web Proxy which is 'External' of the device.  Please see the link below for more information on the configuration.

• Connecting two cisco ESW 500 series switches.

  Hi Experts,

  I have a basic knowledge of the network and need help.

  I have two switches cisco ESW 500 series and I want to connect with each other.

  Q1 # what type of cable should I use to connect these two CrossOver switches or fiber... What is the advantage of the use of fiber on CrossOver. ?

  Q2 # what are the ports marked in the image used to...?

  

  Hi tech spec.

  You can use copper or fiber. You can use directly through crossover is not necessary. Fiber is generally more reliable, can offer a higher flow and distances much longer if needed. You will need to buy SFP modules to connect the fiber switches, which is an added expense.

  The ports on the right are shared. If you plug a FPS in the far-right for the fiber port, then the port to the left of it becomes idle. Only port copper or SFP port can be used at the same time. In addition, these ports are usually used for the uplink to another switch or router.

  Please mark this thread as answer or reply if you have any additional questions.

• Protocols for switches 300 and 500 series

  These protocols are supported by the 300 and 500 series switches?

  • TCP
  • UDP/Unicast
  • UDP/Multicast
  • UPnP
  • RTCP
  • RTSP

  Thank you

  Dear Alejandro,

  If you mean the switch weather can pass through these protocols the answer is a definitive Yes. If you meant something can else you please describe what you mean?

  For example, THAT TCP is supported in a way that it can filter traffic based on the TCP port (layer feature 3 +), so can he do to UDP. Multicast is also managed through IGMP support. About RTCP and RTSP how / why would you use it?

  Thank you and best regards,

• Back on the cisco ASA 5500 series and PIX 500 series

  Hello

  I fund a site www http://www.searchsecurity.de/themenkanaele/plattformsicherheit/schwachstellenmanagement/allgemein/articles/106752/ (only in German). I have read that it is possible to make a denial of service on cisco PIX 500 series and series 5500 ASA, when the TTL value is enabled.

  How can I check that? or solve the problem?

  I thank you,

  Mary

  What version of the code you run the Pix or ASA. Refer to the "Products affected" section for more information on versions and the products concerned. This should point you in the right direction.

  Also, listed in the URL is bypasses and fixed Versions that you may want to check.

• Firefox seems to be ignoring DNS TTL and DNS resolved cache indefinitely

  Hello

  Since we started to serve our js and css by CloudFront a few weeks ago, we started to see a problem with Firefox, where these goods would not sometimes be charged.

  So far, the only way I could reproduce the problem has been to load our home page in the afternoon, without closing my browser and then refresh the page the next day morning. I know it's pretty extreme, but some customers reported this problem, which means that it happens in both real life scenarios. We have been able to reproduce it on Windows and OSX from our office in New York and Krakow, Poland.

  I used Firebug to track down this problem and it seems that Firefox is ignoring the TTL of DNS queries when looking for URLS and caches them almost indefinitely. Due to the constant rotation of the CloudFront servers, after enough time the cached IP address server unresponsive and all applications are abandoned (applications abandoned on the screenshots). That sounds like a plausible explanation? Has anyone have the same problem and has a solution for this?

  Screenshot taken: 2013 - 06-13 at 22:29:30 watch the page loaded with success, then one taken on 2013-06-14 at 09:33:30 watch tab firebug "Net" with all requests of the asset given up. Force-refresh the page several times allows, as shown in the screenshot of 09:34:03.

  • HP - printers - HP ENVY 4520 series - error 0 x 80240017

  I'm under 10 Windows Home Edition.

  I was wondering is their someway to hide this update in windows update Windows 10 feel free to explain.  I should also mention that I'm not comfortable to do stuff in the registry.

• No Audio output device is installed (Windows 10 64 bit, HP Pavilion 500 series)

  Model number: 500-007 a

  Operating system: 10 64-bit Windows

  Description of the problem: no sound.

  Hello

  I came from TenForums forum, hoping to find a solution to the problem of noise from my office.

  Status of the solution of the problem is at: http://www.tenforums.com/drivers-hardware/45369-no-audio-output-device-installed.html

  When I move my cursor on the audio icon on the corner at the bottom right of the screen, the message of the index says "no Audio output device is installed". By clicking on the audio icon so that windows are trying to solve the problem will not solve the problem.

  

  In Device Manager, I have 2 "High definition audio controller" that display a yellow "!" mark on them. Both controllers are on the devices tab of system.

  

  As you can see in the picture above, there is no tab "audio, video controller and game."

  How can I get my sound back?

  Thank you.

  You are the very welcome.

  What worries me is that your device manager does not have the IDT HD audio listed under sound video and game controllers Device Manager.

  Normally, when you install W10, the IDT HD audio device is in the list, and it just doesn't work.

  You can try reinstalling W10 and see what happens.

• Pavilion 500 series: Windows 10 does not recognize my HP Envy 5532 as a scanner

  Since upgradingg to Windows 10 my printer works, but I can't get the function of scan to post a link to the PC, can you provide any help with this.

  Sometimes I have the same printer. I fell on the same subject. The new driver, which is available at Hp seems to have solved the problem I had.  Here's what I just did.

  (1) uninstall the printer from the printers and devices.

  (2) download the following driver.

  http://support.HP.com/us-en/drivers/selfservice/HP-envy-5500-e-all-in-one-printer-series/5304881/model/5304882#Z7_3054ICK0KGTE30AQO5O3KA30R1

  3) double-click the downloaded installation file.

  (4) follow the prompts.  I chose a wireless installation.

  Once it is finished, you can type in scan in the search window. Choose and click Windows Fax and scan.

  Once you select the printer such as requested by the installation software as seen in the image, click Next.

  

  

  

  Use the HP Print Wizard to manage scanning. He wil have been installed by the HP printer installation software. Use the search box in Winfdows 10 to find or use the apps icon everything.

• HP Pavilion 500 series: updates Bios

  HI I was wondering tonight in my hp support center was a significant update of the Bios I was wondering if I could please get some advice on the question of whether it is a good idea to Bios if there is nothing wrong with the Bios in the first place.  Why should I update the Bios or should I not update the Bios for my hp Desktop.

  Thank you for your time and help

  In general, I agree with redshore.  I'm used to be of the opinion that if everything worked as planned, then leave it alone.  Since I use a HP ENVY laptop with Windows 8.1 one year, I noticed that the HP helper has done several updates that I probably have on my own, especially updates BIOS.  I don't know why there would be many updates to BIOS, so have to asuume engineers tried to fix a problem that had been reported.  As redshore, you always stand the risk of bricking the unit with BIOS update is bad and if you read the forums here, there seems to be more those happening.

  Some units now have a feature where a regime of BIOS recorvery is integrated, a good idea.  You might wise to explore your PC to see if the model you have this feature for a while where you might need.
