UPnP Broken - Does Not Detect All Devices
Feb 8, 2011
I have two Windows 7 computers, my Desktop, and my Laptop. I also have UPnP capable router, Xbox 360, and networked printer.
Everything used to work fine, but I just noticed the UPnP on my desktop seems broken. I changed my motherboard and CPU about a month ago on it, so I think that may have something to do with it.
My laptop is able to detect all devices fine, but my desktop can only detect my laptop. My laptop can stream music from my desktop, but no other devices can. I have tried completely turning off the firewall, so it isn't that. My desktop can see my Xbox in the network map, but doesn't list it in "Network"

I have an Iogear bluetooth dongle that until a couple of weeks ago was working fine. I use it to connect to a bluetooth keyboard. I went on a trip and took the keyboard with me, where I paired it with my iPad. When I came back, the bluetooth could no longer find the keyboard, or any other bluetooth device for that matter.I've gone through all of the usual troubleshooting steps, including making sure it is set to run automatically, making sure the device drivers are updated, removing and reinstalling the device drivers, making sure the bluetooth settings are correct as far as set to find devices etc. with no luck.It does appear to be working as far as the device goes. There is a blue light on the dongle that blinks when I click to find a bluetooth device. When I put the bluetooth on the computer into discover mode, my phone is able to find the bluetooth radio, but it cannot connect with it. All of this, and the fact that it worked fine before, leads me to believe it may be a problem with my computer. I ran antivirus software, and although it found a couple of malware programs, nothing changed.

My USB 3.0 ports aren't working. I have 2 USB 3.0 front ports that are hooked up to the motherboard and 2 addition USB 3.0 ports back ports pre-installed on the motherboard. None of the four can detect my USB 2.0 devices. The USB 2.0 ports works fine.

I recently updated my nVidia drivers to the latest and also my SiSandra Lite software (for quick access to accurate specs of my PC). After updating SiSandra Lite, I looked at the GPU section. As usual it loaded the primary monitor first where everything was fine. I then changed to look at my secondary and my primary monitor turned off and my desktop was shifted to my second.Now when I boot my computer, my primary comes on, but after the pre and post bios. Only when Grub comes on does something appear on my primary monitor, but it's very low resolution (compared to what it used to be). The windows 7 loading bar appears on my primary but before the logo can appear and glow, it swaps to my secondary monitor where it stays.
Windows 7 cannot detect my primary monitor trying both screen resolution detection and it's missing from the devices menu. Really confused about this whole business.I realise this may have been posted as a problem before. I did find little snippets of information about it but nothing sufficient.

I have 2 PC's setup with windows 7 x64 7600, one is my main PC and the other is my HTPC.
My HTPC is opening up UDP port 54838 via UPnP on startup, with out any applications starting.
This is a fresh install with no software other than iMon which is for the remote and VFD.
I have run tcpview and currport to see what is doing this, but they only show that the port is open and not what is associated with it. Have also run Sysinternals Autoruns, which lists everything that is running as a service or as a program, and I can see nothing suspicious !
I also have downloaded a free version of UPnP Explorer, but this only displays info on the physical router side of things.
I have searched the net and can find no mention of UDP port 54838 anywhere whatsoever, and have checked all of the port listing sites and none of them have any details of this port number, other than it is in the dynamic private range ... so it could be anything
I have tried to create a firewall rule to block it, but UPnP just creates another rule to enable it !
I know that the simple answer is to turn off UPnP, but I do actually use it for quite a few applications and devices so it would be a pain to do so as UPnP works really well with multiple devices that switch from wired to wireless mode and with dynamic IP's.
Has anyone got any ideas on a) what this port might be and b) if not, what else I can do to track it down ?
I don't want to get paranoid about it but I am security conscious enough to want to know what is making connections outside of my network with out my permission.

Just wondered if there's a way to open 2 ports via UPnP (specifically 113 and 3389) on startup, as my silly router refuses to give my computer the same IP every time. Yes, I know I could set my IP as static locally, however, I move my computer to various locations to "share" things?

My xbox has been connected as a media center extender to this computer and router combination for several months now. The router is a Buffalo WZR-HP-G300NH. Earlier this week the media center extender was having trouble playing back video. After a restart of the computer the extender was no longer connected.When I try to add a new extender I get the message "Cannot add extender". Microsoft says to enable upnp and multicast. Check. Reflashed firmware to dd-wrt. No luck. Flash back to buffalo firmware. No luck. Try an old Linksys WRT54GL I have lying around. No Luck.The event logger has this error: "Media Center Extender Setup failed as the Extender was detected on the network but the UPnP search for the Extender failed (timed out after 20000ms)." Event ID: 538 Now I've done everything I could find about enabling network discovery, allowing anything to access media and such. Network and sharing is set pretty much wide open. I've also tried switching between home and work networks.With that said, I decided to check and see what updates have been installed. It turns out that an update was applied on the day I started having problems. It says it cannot be uninstalled. Description of the Windows 7 and Windows Server 2008 R2 installation software feature update Note: I do not have system restore points. Small SSD and didn't take the time to figure out how to save them elsewhere.

I have been unable to connect to anything on my wired network, for about the last week. I don't remember making any changes however, I just became unable to connect.I having done a little troubleshooting.1. I can connect to the shares of my Windows Home Server if I use the IP address. The name does not resolve.2. Flushed DNS and restarting DNS server. Flushing DNS works on one client, to allow browsing by the name & restarting DNS works on the other. However neither works after a restart.3. Only my Wifi clients are experiencing this issue. My wired clients, desktops, PS3, Xbox 360, and Boxee can connect perfectly.This issue is not limited to my server. I can't connect to shares on my desktop, nor print to my wired printer.Some network background:I have DSL through CenturyLink and have a Linksys E2000 router.

I have a compaq cq56-115dx latop, and looking for some input on a problem I have. I attempted to upgrage my ram from 2 gb to 5gb. The 4 gb chip went in ok on the bottom slot, however, when placing second 1 gb chip, I accidentally broke the levers. Since it was now broken I decided, to see what would happen if I gently replaced cover, to hold chip in place, ad screwed cover on firmly. Turned on laptop, and all is working fine, including all 5 gb memory is available. My question is should I leave it the way it is, or should I have it fixed properly. FYI the cover over the chip is vented.

I was talking to some friends over skype when i needed to log out and my mic was fine there were no problems with it. i logged out and when i logged back in and called a friend up on skype he could not hear me talking the only thing he could hear was a loud static noise. i went to configure the settings but it said i tried everything and it would still make the noise. i tried plugging in a brand new mic that has never been used before i took it out of the packaging and plugged it in and still the same problem.

I recently tested windows 7, 6801 only because you cant get the beta in 64 bit yet. Anyway. I use 2 260 gtx and under windows 7 games play much better than in vista BUT they would only run properly when sli was disabled. SLI mode in windows 7 for me was totally broken. The computer would freeze and not recover. The only way was to reset the computer. I hope it is only a driver issue since they do not make graphics drivers for 7 yet but geeze that really sucks. Is anyone else using sli in 7? I used 64 bit.

So the SATA connector on my old 64GB SSD snapped off, now it's become a crap shoot just trying to get the bios to recognize it. I've already accepted I'll need to RMA this one, and even bought a bigger replacement for it.to the nature of my OS install I am a bit confused as to how I should go about reinstalling windows. I'd put the main OS files (and drivers) on the SSD, while storing the users folders and everything else on my larger HD. Now however I am left with just my windows 7 install disc, and a 1TB harddrive I know has my user folders on it.How should I go about installing it? Is there an easy way to simply use the already established folders and the like, instead of manually moving/deleting the old ones?

I was playing total war shogun 2 on windows 7. Diagonal lines started shooting out of the characters, square block patterns start flashing all over the place. The graphics got progressevley worse and worse so i took in. They tested the graphics card and it was fine so they restarted the computer and then windows crashed. They reinstalled windows 7 and i started putting everything back together.
I just put total war back on my computer and started playing and its started again. I restarted my computer and all that came back was a blinking undersscore. Luckily i shutdown and it started normally but the graphics are still messed up.

i have been attempting to open some .exe files but keep on getting the message 'not a vaild win32 application'. A scan with Super Anti spyware shows the following - System Broken File Association HKCR\.exe. I am assuming that something is wrong with the .exe link. I have checked the list of defaults and noticed that the .exe default was missing. I have also tried some fixes which appear to attempt to change the registry, but these have not worked. Do i need to manually change some registry content?

i moved into a new house last week and when i turned on my pc i noticed how there was a 3/4 inch black gap between where the screen displayed colour and the end of the screen. I have installed the newest graphics drivers on my sapphire radeon 4850HD but it doesn't seem to change.. There are no new important windows updates, which i thought it would've fixed it in the first place. anyone have any idea?

Intel G45 WDDM drivers are highly unstable and give consistant BSODs in media center. This includes the drivers that ship with Windows 7 RC (7100). Any ideas where/when we can get some more stable/better drivers?

i have 2 hard drives, one running xp, one running windows 7.
up until recently they have been working fine together, but i think i had/have a virus and it trashed my XP drive (crashes right after desktop loads) which is no worry to me.
my worry is every time i try to boot into windows 7, i recieve the "BOOTMGR IS MISSING - CNTRL ALT DLT TO RESTART" error.
i have tried a bunch of things like attempting to move the bootmgr file from the XP drive to the windows one, and trying to create the bootmgr on the Windows 7 drive, but no luck.
so my question is how can i get windows 7 to boot indepentantly from my messed up XP drive, casue the boot files are on the xp one.

I installed a retail version of W 7 on a Fujitsu which broke 6 months ago and cannot be restarted. Now I cannot activate the installation on my replacement computer and the support is less than useful, always referring back to an automated system. I transferred the HD from the old computer to the new but cannot see a way to uninstall the windows 7 from that disc. Trying help by telephone was impossible because of excruciating bad connection.

Wifes Dell with XP blew up mother board and corrupted boot files. Placed drive as slave in my machine. Drive works fine, can access all needed stuff, can't boot it. I can access Favorites, Address book files from Outlook express, photos. I copied all the important things also to a seperate folder on a My book USB drive. Can I install the My book to her new computer running 7 ultimate 32 bit and just drag and drop or copy to the favorites file while in the explorer pane? She was running IE7. Also how can I put all of her address book from Outlook Express into Outlook 2010?

Yesterday my friend needed me to test something for him in MySQL, a program I had installed a while back. When I tried to get in, it told me that I needed a root password. Since I forgot that, and I had no idea how to log in, I used Revo Uninstaller Pro to uninstall MySQL and delete all the leftover files and registry values that it left behind. I'm not sure if that is what caused it or something else that I can't remember, but since last night a lot of my computer services aren't working.For one thing, I can't log into MySQL.I can't install/uninstall any programs. - Solved.I have my Control Panel listed as a menu in my Start list, but when I highlight it, it shows the Control Panel as empty.I can't turn on my Windows Security CenterI can't access/turn on System Restore and clicking on 'Turn System Restore on or off' does nothing.I can't access System Information - Solved.or System Properties - Solved.In addition, I can't click the properties of any folder (If I try to right click My Computer and hit properties, nothing happens), my computers sound is not working, my taskbar shows my internet as offline even though its working and I can't open pictures - Solved.I also cannot run SFC / Scannow - Solved.or run Windows Update - Solved.I also feel like there might be something wrong with my graphics diver, because as I've been typing this post, my screen keeps flashing to my desktop - Solved.I cannot pull up my specs using the program 'Speccy' because it says Class Not Registered for everything. I've also lost the CD for my Windows 7 Ultimate, so I don't know if I could use that to fix it. - Solved.Edit 1: My video driver was in fact affected by it, as I can't watch any videos, and attempting to crashes my firefox plugin process.

Have owned a Palm Z 72 for about 5 years now and have loved it. The only problem I have ever had is an occasional freezing up which does not last long. Now though I am in serious trouble. The little pin inside where you plug in to charge it seems to have broken off and I have no way to charge it.I cannot hot sync anything to my computer because my desktop died and I purchased a laptop with Windows 7. There does not seem to be anything for Windows 7 for or at least I can't find it.I have bought a Palm Pre Plus phone and you would think I could get these 2 to talk to each other, but it's beyond me.
