Why Media Center interfere with the master of local network discovery?

At home, I have a mixed network of 5 win7, XP 3, xbox, pills and devices multimedia TV.

The network relies on a specific working group name (that all windows computers use) not homegroup.

This works well until my Win7 computer that is configured as a DVR with media center becomes the 'master' for LANs to discover.  Then only the Win7 computers on my local network.  All the XP computers disappear.

Why is this and how do I solve this problem?

It feels like the 'master' for local networks is chosen randomly.

Why Media Center interfere?

Can I stop this interference or inhibit the computer to be ever "master local network media center?"

I use a free app called lanscan to give me a list of computers available in each perspective of computers.  When the broken state this app fails to list anything except on the Media Center computer.  Lanscan also shows the computer hosting the network discovery.

Thanks in advance.

I have over 30 years of experience with computers but my network is just enough to get me in trouble (and keep changing the rules)

  • Xbox 360 and Windows Media Center interfere with the operation of the Vista computer.

    Since the implementation of an Xbox 360 for the family to use, turning power switch and return to the dashboard caused Windows Media Center on the laptop family to turn on automatically, which, in some cases, interrupts programs and blocks computer. Sometimes the computer will be same turns on automatically when the XBox is turned on.

    I've done everything I can think of to stop the problem, including 'disconnect' XBox WMC in the "Uninstall" the XBox and the XBox settings in the settings of WMC. I do not anticipate using WMC in the near future, I just want to stop this crazy to happen.

    Thanks in advance for any help and please ask if you need more information on my problem.

    Hello ebduhamel,

    1. what type of connection you have between the computer and the Xbox, it's a cable or a wireless connection?

    2. is it to wake up the computer from standby or everything just stops?

    I suggest you try the steps below and check if you have the same problem.

    This could be possible only if media sharing is enabled on your computer.

    I suggest that you turn off media sharing and make sure you always have the same question:

    a. click the arrow below the Library tab, and then click media sharing.

    b. turn off media to find that others share and share my media to check boxes, and then click OK.

    By clicking OK, you confirm that you want to turn off sharing for yourself. You will also be asked if you want to turn off sharing for everyone who uses this computer. Note that if you let one of the selected check boxes, some sharing services may continue to run in the background.

    c. When you are prompted to turn off sharing for everyone who uses the computer, follow these steps:

    I have an HP dv6000t. He came with Yuan EC680 ExpressCard analog TV

    but after downgrading to XP MCE 2005. XP MCE 2005 was the ORIGINAL OS
    on the system (bought in November 2006). I've updated the drivers for the TWO

    address this problem. Any suggestion on how to solve this problem would be greatly
    appreciated. What HP had try me, including Sofpaq fixes are not
    address my problem. It does not give the error "IR hardware not detected".
    overnight, it correctly detects the signal from my digital cable box.
    The main problem could partly be the we FINALLY converted to digital television
    signal and I always try to use the analog tuner ExpressCard? Once again
    any help is greatly appreciated.

    I found this fix on another site.  We're supposed to plug the IR cable to the TV box at the back of the first port on the remote sensor Windows Media (the ' antenna' of the Windows Media Center remote control) and then to put the tip of the probe of the IR cable to the cable TV box distance near the sensor on the cable box (it can be seen by a light in the glass) and then complete the configuration of the channels in Windows Media.  The problem is, it does not work unless there is also something connected to Port 2 of the medial distance sensor Windows as well (a head set will do).  With the sensor box IR cable company cable plugged into the first port in the back of the remote Windows Media sensor and headphones plugged into Port 2 of the remote sensor, Windows Media, and the end of the probe of the sensor cable box IR cable near the cable box remote sensor box, Window Media channel setup "found" the cable of the IR sensor and allow me to complete the installation.  I could not bind the Windows Media remote sensor with the remote for the cable box, but said that I managed.  I use the remote cable box to change channels and have box IR cable connected on the decoder cable TV and put the cable box IR receiver cable on top of my desk.

    Original title: when setting up Windows Media Center, I get the error message: "IR hardware not detected".

    I have an internal TV Tuner that has been installed by HP, when I bought recently a "computer build-your-own." (According to the control panel Device Manager, my tuner is a Win TV HVR 1290, made by Hauppauge). The computer came with Windows 7. While installing Windows Media Center, after setting up the TV Signal (on channel 3) I am able to see a video thumbnail on my computer screen. I am also able to change the channel using my remote control U-Verse (not the Windows remote control supplied with the computer). So far so good! I then hit next and get the following message: "Windows Media Center cannot detect the IR control cables, which are necessary to control the set-top box. Fixing parts IR that supports the IR control cables and then try again. IR HARDWARE NOT FOUND ".  After you receive this message, the installation procedure is completed. I called HP that support intalled the tuner. They had not the slightest idea what to do. I then called Hauppage customer (manufacturer of TV Tuner). They said that I need to plug one end of the IR Blaster cable that shipped with the computer in a slot in the back of my computer (they told me which slot). They said so to run the IR all the way cable to my cable box and the other end of the cable to my cable box of band. They said it was necessary to be able to use my Microsoft Remote to instruct the box to change channels (cable IR stuck on the box). I told her that I did not use the Microsoft Remote, I could change the channel with my U-verse remote (that I preferred to use anyway). He said that it took the cable on the band decoder in order to remove the error message and the installation of Windows Media Center. I then called U-Verse technical adapter who informed me of their set-top boxes (made by Cisco Systems) do not have the ability to receive signals IR IR Blaster cable (or any othe IR signal source). Microsoft is apparently not understand how U-Verse set-top boxes are designed to work and sells a product incompatible remote control/IR. My question is this: How do I set up Windows Media Center, in order to avoid getting the error message "IR hardware not detected" when you install Windows Media Center and just use the remote control of the U-Verse that I prefer to use in the first place. Once understand you this point, please send the information to HP, At & T U-Verse and others. Thank you.

    Hi, I had the time of IR not detected in Windows 7 Ultimate with a TV wonder 650 card and a box of digital adapter from Verizon for my PC... Go on the road to installation and after the Media Center channel search, choose manual configuration. Choose the aerial signal (I aso picked after this analog) l. After he sought more, he finds no channels.  Do not be afraid. Just accept it and go to the main settings page in the Mediacenter. If I remember correctly, then select TV Guide. Choose Add channel. I added the channel 3.

    Since my Verizon box has no IR for the computer, I added the channel 3 for the media Center and I change the channels with my Verizon remote. All my stations in the Verizon box go to Channel 3.

    The story here is so, for some reason any Windows detects that only my box channel signal TV and you must manually configure the media center on the air, then go to settings and add the channel you want in the guide.

    Why the guide TV control which channel you can tune is beyond me, but the scanner locks all channels, it does not detect. they must be added manually in the guide.

    My TV works and looks okay now.

    It actually works!

    the only problem is that it is not in HD

    Can I use Vista Media Center to record only TV etc...

    Vista recognize the Remote Setup Box, but it is not able to change the channels of the Remote Microsoft.

    On this page: http://mythtv.org/wiki/MCE_Remote I have the 3rd remote from left to right.

    I contacted PACE (the author of the configuration box) with the following response:
    ". The DC - 50 X uses a new remote protocol called XMP. Check to see if it can emit IR codes using the XMP Protocol.
    "If you use Microsoft remote issue codes using the XMP Protocol, it will not work with the DC 50 x
    "

    Anyone know if Microsoft Remote is able to use the XMP?

    Someone knows how the Media Center as the configuration box to change the channel?
    It looks like, it uses IR (due to the extra step of IR with the configuration box).

    If you have a WMC working with the DC50X, what is your Setup, what version of the distance, whats is your hardware configuration?

  • Win 7 Media center must rebuild the library whenever he starts.

    I have a frustrating problem with Media Center in Windows 7.  He is a dedicated Media PC that is used primarily for music.  Whenever I have run media center and select the music option, remember all the information of the library for each category.  Since it loads in album it takes 5 to 10 min. to get information (albums, works of art, etc.). Then when I go to the Genre, he goes through the same process.  This is repeated whenever I select a new category.

    As long as the PC is on and information process was done once for each category, it works better.  Once the PC is turned off and restarted it must go through this process again.

    I used Media Center in XP for years and once he has sought and collected built the library is easy to use.  When the PC is started again click MC select music and all loads of information in a few seconds.  It seems that MC in win 7 is a step backward, unless there is something I am doing wrong.

    I downloaded the drivers for my sound card. display and motherboard.  All files are stored on the PC.  I had the problem on three separate PCs.  Although two of them, I went back to XP.  Before going back on the third, I want to see if there is something I can do wrong.

    I suggest that you try to reset the media library of WMP. Note firstly reset the library will make you lose all play counts and ratings too. Then, follow these steps:

    -Restart the PC.
    -Click Start, type services.msc in the search field and press ENTER. In Services, locate the Windows Media Player Network Sharing Service . If its status is started , double-click the service, and then click stop .
    -Click Start, type %LOCALAPPDATA%\Microsoft in the search field and press ENTER. This folder opens in Windows Explorer.
    -In this folder, rename the folder Media Player as Old Media Player . If you do not see the folder, then it is probably hidden. Set Explorer to view the hidden files and folders and show protected system files.
    -Launch WMP, your library will have been reset and will be rebuilt. Check if the problem persists. Tim Baets

  • Cannot get remote windows media center to change the channel on Cisco DTA50! Help!

    During the TV signal together towards the top there is no option for "Cisco".  Then I select "Unlisted" and setting up tells me there is nothing that can be done and leave the whole upward. Media Center will learn the remote control IR codes because it does not pick up the DTA remote this process.   I was finally able to get a "tv signal" implemented by choosing comcast, although this isn't my cable tv company, , but still the wmc remote will not change channels on the DTA cisco. The wmc remote works fine and changes channels in the real of windows media center, but because the string must be changed on the real DTA there on some channel I entered on the DTA remote. Since I use record TV WMC, indicates on the guide, it's impossible, unless I can get the DISTANCE WMC, put in place to change the DTA channels!

    I need help!

    I was finally able to set up the remote after tweaking autour with IR receiver. I have even connected infrared diffuser!

  • VMware Player (VMware Workstation?) Interfere with the connection of the browser

    I looked for this in order to make the version of the-what? -VMware Player or VMware Workstation I, and in order to find the right users Guide or manual.

    But this isn't my problem entirely.

    My problem is that I was using my HTTP (browser) client and it has been noticed that I could not connect to certain websites (e.g., http://www.gnu.org/).  I can do that at home, through my wireless router (configured for IP) static on the local network.  Then I go to work where I use the ethernet connection (not getting any IP by DHCP!... configured for a static IP address on the WAN).  I call tech info, that says they can connect.  I think it's because I'm using OpenDNS instead of the name of University servers, and then I enter the "Network Sharing Center' and see 'several networks' and THREE Local (ethernet) connections.

    After that think "WTF?" and think that 2 local connections and 3 are screwing things up, I disable all local connections and re-enable the connection with the hardware ethernet card.  Who has NOT solved the problem of my failed to connect to the web site, that is

    http://grub4dos.sourceforge.NET/

    The service

    http://GSiteCrawler.com/tools/server-status.aspx

    reports the HTTP 200 response code very quickly.  I use this service to see if the info tech group workplace blocks a web site.

    However, I want to learn more about virtual network maps created by the VMware Player (desktop?).  I ran the "vmnetcfg.exe" interface and in the Summary tab, see:

    Virtual network

    Activated

    VMnet8 (NAT)

    192.168.219.0

    Activated

    The guide I want to read should explain what are these local ethernet adapters and they can interfere with the operation of the host outside of the virtual machine.

    Thank you

    Welcome to the forums!

    The guide: http://pubs.vmware.com/ws7_ace26/ws_user/ws_net.html#989125

    Where is your problem to browse occur? In comments or host?

    VMnet0 is the virtual bridged network. He connected the virtual NETWORK adapter of your guests who are bridge transparently to your physical network device.

    VMnet1 is the network invited only, a virtual, where the host and the guests are members of. You see a VMnet1 NIC on the host, because it's the virtual card that the host uses to connect to VMnet1.

    VMnet8 is the NAT network. It connects to each stack TCP/IP Protocol on the host computer. Therefore the guest may use any communication device that uses TCP/IP. Th egust is hidden behind the NAT device. This means that all packets leaving the host, coming from the prompt appear to come from the host. VMnet8 virtual card is one that connects to the host on VMnet8 virtual network to enable external communication for the customer.

  • How a microwave oven interferes with the WIFI signal?

    MICRO-WIFI INTERFERENCE

    Please explain THAT HOW A MICROWAVE actually INTERFERES with the laptop WIFI signal...  How to turn off the oven microwave takes the PC adapter, for example?  When the microwave oven is off and don't use it, should also be disconnected? In the equipped cafes in WIFI, are microwave ovens, degrading the quality of the signal?

    I thank very you much for your comments.
    Joe

    This is caused by the fact that both microwave and most wifi routers operate at a frequency of 2.4 Ghz, there is a setting on some wifi routers that allow you to operate at 5 GHz, but this frequency moves not by walls well, insofar as they interfere, the microwave should not disseminate its frequency outside the oven microwave and most of the routers wifi broadcast in all the directions, radio waves can bounce off the walls and envelope the room and other areas as well, this isn't a line of site, so unless you have your computer very close to the microwave you should not receive any interference at all. or course, if you stick the router inside the microwave.

    Hope this helps,
