  • Mouse receiver stopped working after pairing mouse to an unifying receiver

    - by mp19uy
    I bought this mouse, logitech m510, which came with a nano receiver (no-unifying). Yes I know, the mouse is supposed to come with a unifying receiver but I bought it knowing that it won't come on it's original package and it will come with a no-unifying receiver. When I received it, everything worked ok but, after connecting the mouse to another computer using an unifying receiver (that also worked ok, btw), then, when I tried to connect back the mouse to my computer using the no-unifying receiver, I couldn't connect it. I tried everything from removing the batteries and reinstalling the drivers to restarting the computer and trying in different computers, but I couldn't connect them. What I think it happened, is that in fact if you check the documentation of the logitech m510 it says that it works with unifying receivers only, and even more, there is the following article explaining it: http://logitech-en-amr.custhelp.com/app/answers/detail/a_id/18001/~/using-my-m510-with-a-different-usb-receiver So my theory is that the problem was connecting it to a unifying receiver, and now, isn't recognize by another receiver. The receiver (the no-unifying one) itself is recognized by windows, and if I connect the mouse using a unifying receiver, it works. I would like to know if there is any know solution for this or if I can try something else to see if I can solve this.

  • How to edit known_hosts when several hosts share the same IP and DNS name?

    - by Frédéric Grosshans
    I regularly ssh into a computer which is a dual-boot OS X / Linux computer. The two OS instance do not share the same host key, so they can be seen as two host sharing the same IP and DNS. Let's say the IP is 192.168.0.9, and the names are hostname and hostname.domainname As far as I understood, the solution to be able to connect to the two host is to add them both to the ~/.ssh/know_hosts file. However, it is easier said than done, because the file is hashed, and has probably several entries per host (192.168.0.9, hostname, hostname.domainname). As a consequence, I have the following warning Warning: the ECDSA host key for 'hostname' differs from the key for the IP address '192.168.0.9' Is there an easy way to edit the known_hosts file, while keeping the hashes. For example, how can I find the lines corresponding to a given hostame? How can I generate the hashes for some known hosts? The ideal solution would allow me to connect to seamlessly to this computer with ssh, no matter whether I call it 192.168.0.9, hostname or hostname.domainname, nor if it uses its Linux hostkey or its OSX hostkey. However, I still want to receive a warning if there is a real man-in-the middle attack, i.e. if another key than these two is used.

  • Possible boot conflict?

    - by Evan Kroske
    I was installing Ubuntu on a computer on which Windows XP was already installed. The computer has multiple hard drive bays, so I decided to remove the XP HDD and install Ubuntu on a blank HDD when it was the only HDD in the system. Unfortunately, if I now try to boot Ubuntu with the Windows XP drive in the second slot, nothing will boot. However, if Windows XP is in the first slot, it will boot fine. Can anybody explain why this happens? When I was checking out the BIOS to see if something was messed up, I discovered that when Ubuntu is in the first slot, the BIOS doesn't recognize any HDDs. However, if XP is in the first slot, the BIOS recognizes both drives. Any hypotheses about why this happens? Edit: Here's the setup. I have an old server with seven SCSI HDD slots. I have five identical 68 Gb SCSI drives, but I can keep only two plugged in. XP is still installed on the first drive, but I reinstalled Ubuntu on the second drive and had Grub overwrite the XP bootloader on the first drive. Now, the setup works fine, and I can use Grub to load either XP or Ubuntu. However, if I plug in another identical blank HDD in the third slot, the computer recognizes only the XP drive and doesn't boot. Grub starts to load, then gives me a "disk not found" error. Running ls from the grub rescue prompt only shows one drive with two partitions. I guess this is a BIOS problem, but I'd still like to know what triggers it. What about a blank drive could cause the BIOS to freak out?

  • Can I make my PC backup and then sleep on demand with WHS?

    - by Simon
    I really hate the way that WHS backs up at a particular time in the morning. First of all I don't EVER want my computer turning on when I am not there. EVER. I have a Core-i7 laptop which literally could burn the house down quite easily if it were to turn on in a bag. I also don't ever want my PC to sleep unless I tell it to. I don't have hibernation or sleep enabled and this is the only way that WHS will sleep after a backup is complete. I know that Windows 7 has the ability to disable waking up when on battery power but it doesn't seem to work on my laptop. These are the possibilities (with wake timers left as default): 'Wake this computer for backup' ON - it turns on in my bag if i forget to turn it off - and stays on when the backup is complete. 'Wake this computer for backup' OFF - it backs up in the morning, but I need to leave the machine on all night. I say 'Backup Now' and then it backs up immediately. I can turn it off when its done if I'm still awake, but then that backup appears as 'locked' in the console and not 'automatically managed'. What I'd really like to do is : Click 'Backup and Sleep' and then go to bed. It will backup immediately and then sleep the PC. This backup must be 'automatically managed' and not appear as a 'locked backup' in my console Show me a confirmation that everything was backed up successfully (or not) when I turn it on. Is there any way to achieve this?

  • Membership in two domains

    - by imagodei
    Hello! I would your suggestions for an effective solution for a person, who needs to access resources in two Windows domains and wants to use one computer. It's about our CEO, who has accepted a second position in another company. Accessing files and folders isn't big problem. The greatest challenge I see is that he wants to conveniently access Exchange accounts in both companies; he would like to send and receive mail in single Outlook if possible (two profiles?) There is also a challenge with calendars: he would like to have one calendar for all activities from both Exchange accounts. Creating a POP3 account for accessing second Exchange server is a last resort, because obviously there is a problem with scheduling meetings and other calendar related tasks. Forwarding and receiving all mail/tasks on primary Exchange server is inconvenient because simple replying to original sender is disabled; and also when manually changing the recepient, he will receive mail from the wrong address. We were considering Virtualisation, that is setting up an instance of virtual machine inside existing installation and then joining this virtual computer to a second domain. Then installing another MS Outlook. This would of course mean two different Outlook accounts, two different calendars, but would at least enable our CEO to access all information from a single laptop. Does anyone have any other idea? I know setting up two domains on a single computer is a no-go (without much hacking at least), but effective workarounds are appreciate. The thing I am looking here is high usage/efficiency/productivity, but also as elegant solution from the administration point of view. Thank you very much (if you managed to read this through, this is a good sign ^_^ )

  • Windows 7 Cable Connection Rehabilitation

    - by Giovanni De Gaetano
    I recently switched the operating system of my laptop from Windows XP to Windows 7. My web-connection is such that I need to identify everytime before connecting. Since there is no automatic identification request, while using Windows XP I was used to de-abilitate and rehabilitate the cable connection after every switching on. I successfully installed the web-connection on Windows 7, and later on I switched the computer off and on (simply because I had to sleep!). After restarting the computer, since there was no automatic identification request, I de-abilitate the cable connection. But this time I didn't find any way to rehabilitate it! Do you have any suggestions on how to solve the problem? My "Wired AutoConfiguration" has the startup type "Automatic", but it's not enough to restart automatically the cable connection! I tried to do some standard things like restart the computer, unplug and plug in again the cable, reinstall the web-connection from the scratch... But nothing worked! Thank you very much for your help!

  • Wiring my internet

    - by u8sand
    I have Verizon internet service and am currently using wifi. My router is in the basement and my desktop computer is 2 floors and on the other side of the house above it... Worst possible positioning but that's just how things worked out. My wireless currently is extremely unstable so I've decide to correct the problem by wiring my computer directly. The problem lies here: when redoing the room next to it (when the wall was open) we went ahead and wired some coaxial cable from our attic to our basement (with plenty of slack on both ends, don't ask me why we didn't go ahead and wire a CAT6 cable). The question is: Can I use the coaxial cable to bring me internet connection? Naturally the router (which needs to stay where it is) takes a coaxial cable input and has Ethernet outputs. So maybe I would have to take a ethernet cable, convert to coaxial-coaxial to my computer, convert back to ethernet. Is this even possible to convert from coaxial to ethernet? Or do I have to attempt to go ahead and fish a cat6 cable through my house. I cannot just split the signal because that would require two routers and two networks (which I don't believe would work with one cable-one ISP correct me if I'm wrong). Thanks

  • The USB mouse sticks in Windows 7 after automatic attempt to fix the boot

    - by chelder
    Avast Antivirus asked me to delete a probable virus and to restart to perform a checking. I had to stop the checking at the middle of the procedure as I needed the computer. It was imposible to turn off the computer pushing the power button (as it entered in suspension mode, no matter how long I kept pushed the power button). I removed the battery as the only way to restart the computer. Windows 7 said that there is a problem to iniziate Windows. Windows 7 tried to fix the problem without success. Windows 7 started after that though. Everything is OK but the USB mouse. The USB mouse sticks and freezes each couple of seconds more or less. The tactile mouse (PS2) works well. I googled for solutions but the posible solutions didn't work for me. What happened? How could I fix it without formatting and reinstalling everything? UPDATE: this is what I did: Change the mouse from one usb port to another Test another mouse Set the number of cores of the CPU manually with msconfig Power management: not disable usb ports Check hard disk errors

  • Arch Linux drops me on my school network

    - by Kravlin
    I'm running a Lenovo X61 which i carry around my college for getting on the internet at various points in the day. The network has always been finicky but recently it's gotten worse. I'll connect using iwconfig, get an ip from dhcpcd and log in using vpnc to their system. Sometimes I'll stay connected for hours but most of the time within 30 seconds my network traffic will drop to zero and i'll be unable to do anything. My computer still belives it's connected, however to try again i need to put my wireless interface down, put it back up and try again. It's gotten so bad that i've got a window on my computer pinging yahoo or google constantly in order to know if i'm still able to get online. I know other people who have used Arch Linux that don't have the same problems as well as people who use Ubuntu who haven't had any problems either. It seems like my computer is a special case. Does anyone have any suggestions on how to fix it? dmesg doesn't show anything out of the ordinary going on and i don't know where else to look for errors or other things to try. Edit: this doesn't happen on my home network. It's a problem that only happens at school.

  • How to figure out what VirtualBox did?

    - by AndrejaKo
    I'm trying to boot a custom made-in-ASM OS on my recent laptop. The OS is intended to be installed on a floppy and during make creates a bootable floppy. Since I don't have a floppy drive, I installed it on a virtual floppy. After that I used WinToFlash's create bootable MS-DOS USB drive option to transfer the floppy image to an USB flash drive. Then I tried to boot my computer from it but got only a repeating broken string on screen. After all that I made a virtual hard disk image form the flash drive using this tutorial and tried to boot a virtual machine from it. First time I got same problem as on real computer. I then used the reset option and next time and every time after that OS booted correctly. My question is: How do I figure out what exactly happened to the virtual machine between first and second boot? UPDATE I just created a new VM with default settings for windows XP and it has the same problem that I have on a real computer. I was unable to reproduce the procedure which made the first VM work correctly.

  • Boot sequence unlike reboot

    - by samgoody
    When I turn on the computer it acts very differently than when I reboot it. [WinXP Pro, Intel Core2 6600, 2.4GHZ, 2GB RAM, NVIDA GeForce] Boot: Monitor must be plugged into the motherboard or no image. Screen resolution 800x600. Changes to the resolution cause only the top half of the screen to be usable, and are lost when I shut down the computer. Desktop icons arranged in neat rows on left of desktop. Nothing of note in system tray In Device Manger - Display adapter: Intel(R) Q965/Q963 Express Chipset Family In Device Manger - Monitors, two monitors are listed Hibernate and standby work. Reboot: Monitor must be plugged into the graphics card or no image. Screen resolution - 1280x1024 Desktop icons arranged in the cute circle that I put them in. NVIDIA icon shows in system tray. In Device Manger - Display adapter: NVIDA GeForce 6200LE In Device Manger - Monitors, one monitor is listed Hibernate and standby do not work. When awakened after a hibernation it says: The system could not be restarted from its previous location because the restoration image is corrupt. Delete restoration data & proceed to system boot? Double reboot (inconsistent): Monitor must be plugged into the graphics card. Screen resolution - 1024x768 Odd icon shows in system tray whose tooltip says "Intel Graphics" For a while my morning ritual was to boot, wait, reboot using (alt+ctrl+del - ctrl+u - R), wait. Keeping the monitor plugged into the graphics card. But aside for the inefficiency of this method, I sometimes want to standby and can't. On the other hand, the computer is unusable when set to 800x600. Please help, anyone?

  • Debian, How to convert filesystem from ISO-8859-1 into UTF-8?

    - by Johan
    I have a old pc that is running Debian stable, that is in need of a upgrade. The problem is that it is using latin1 (ISO-8859-1) for everything, and since the rest of the world has moved to UTF-8 I plan to convert this computer as well. And for this question I will focus in on the files that are served with Samba, and some has some latin1 characters in the filenames (like åäö). Now my plan is to move all data of this old computer onto and a brand new one that is running Debian stable (but with UTF-8). Does anybody have a good idea? Thanks Johan Note: later I plan to use iconv to convert the content of some files with something like this: iconv --from-code=ISO-8859-1 --to-code=UTF-8 iso.txt > utf.txt However I don't know of a good way to convert the filesystem it self. Note: Normally I usaly just scp from one computer to the next, but then I end up with latin1 characters in the utf-8 filesystem... Update: Did a small test round with a hand full of files (with funny chars) in the filenames, and that seemed like it could work. convmv -r -f ISO-8859-1 -t UTF-8 * So it was only to execute with the --notest convmv -r -f ISO-8859-1 -t UTF-8 --notest * Nothing more to it.

  • Vista won't boot. BSOD: Page fault in nonpaged area

    - by user31576
    Here's the story: I let Windows Update do the updates it wanted to do, then rebooted the computer. The updating process was taking time so I went away. When I came back, my computer was rebooting. It got as far as the Windows logo with the laoding bar. BSOD'd. Rebooted. And I'm stuck in this loop ever since. Looked up on the net, the "Page fault in nonpaged area" seems to be linked to faulty RAM or drivers. So I ran a memory test, it found no error. When I try in safe mode (with promt) I can see a list of drivers being loaded, then I get the same BSOD. I tried to repair using the Vista DVD, it says "nothing to repair". I tried to restore to a previous state, it says "no restore point found". So, my guess is, it's got something to do with the drivers. How can I identify the one causing the BSOD? If you have any other leads, What can I do? By the way, I'm writing from this very computer, running a linux distro I installed after the BSOD loop started. So i guess it's not an hardware issue. I have backed up important data, and will format and reinstall Windows if I must. But I'd like to avoid that. Thanks in advance for any help you can give me.

  • Why does Outlook 2007 lose connection to Exchange when Windows 7 64-bit turns off display?

    - by Greg R.
    The problem: When Windows 7 puts the display to sleep, Outlook 2007 and also Microsoft Office Communicator 2005 lose the connection to the Exchange server. When I unlock the computer, Outlook is logged out of Exchange and prompts me for credentials (although usually I have to restart Outlook to get it to reconnect). The network connection is still active, e.g. other applications don't lose their connection to the network or Internet when Windows 7 puts the display to sleep. I'm using a Dell E5400 notebook running Windows 7 Enterprise 64-bit with Outlook 2007 connecting to a corporate Exchange server (not sure if it's Exchange 2007 or 2010). The Dell is typically docked and connected via DVI (through the dock) to two Dell monitors. The Power Options in Windows 7 are set as follows: Turn Off The Display: 15 minutes Put The Computer To Sleep: never Those are the "Plugged In" settings but the problematic behavior is the same when running on battery. When Windows 7 turns off the display, it automatically locks the computer. E.g., I have to re-enter my credentials to access the machine. This is per corporate policy. The equivalent set up on my previous Dell notebook running Windows XP SP3 did not result in this problem with Outlook 2007 or Office Communicator 2005 connecting the very same exchange server. The problem began when I switched to the new Dell E5400 with Windows 7.

  • Install and enforce a scheduled task across a Windows domain

    - by Ricket
    We have a small domain of about 70 Windows computers (XP and 7). We want to schedule a command (an update mechanism) to run on all computers periodically, and we want the task to run regardless of the computer's connection to our network (i.e. the task should run even on a laptop that isn't connected to our VPN). We have a Microsoft System Center Essentials 2010 server so that might come in handy. The options I see are these: Do it completely manually. Install the scheduled task by hand or remotely using psexec (and the at command?) for each computer in our network. Enforce that newly imaged computers should have this task installed on them before deployed to the employee, or the task should be in the image. High initial cost (having to do this for each of 70 computers) but building it into the image might work... But there is some maintenance in making sure the task is added to everything. And I fear that a year or two down the road, we will have forgotten about it or gotten sloppy or had new IT employees who miss this step and some computers won't have the task. Having one of our servers run a script that loops through all computers and psexec's the command on each computer in the network -- it would only run on running, connected computers, so this solution wouldn't work. I suspect SCE could do something like this too, but again this is not a good solution. Neither of these are ideal, and I'm certain there is a better way to do it -- right? What is the best way to accomplish this task?

  • Has anyone else experienced page fault crashes with Snow Leopard on MacBook Pro?

    - by BruceMartin
    I bought a Macbook Pro computer on Sept 3rd from MacMall. As I was using it to learn Snow Leopard (this is my first Mac, I am a long time Windows developer), it would crash every one or two hours. After calling Apple support, I dropped it off at the Apple store for diagnostic testing and repair. WhenI picked up the computer from Apple, they told me that it did not crash while they had it. They suspected a software problem, so they had done a fresh install of Snow Leopard for me. At home I went through the start up procedure with the newly installed Snow Leopard. Then I downloaded the iPhone SDK, and the computer crashed again while I was away waiting for the download to finish. I was using a USB mouse, which was the only device attached. No other software installed. I was presented with a dump that mentions terms like "panic", Kernel trap", and "page fault". Does anyone have any idea what this problem might be? I really can not use this MacBook under these circumstances.

  • Installing Numpy locally

    - by Néstor
    I posted this question originally on StackOverflow, but a user suggested I moved it here so here I go! I have an account in a remote computer without root permissions and I needed to install a local version of Python (the remote computer has a version of Python that is incompatible with some codes I have), Numpy and Scipy there. I've been trying to install numpy locally since yesterday, with no success. I successfully installed a local version of Python (2.7.3) in /home/myusername/.local/, so I access to this version of Python by doing /home/myusername/.local/bin/python. I tried two ways of installing Numpy: I downloaded the lastest stable version of Numpy from the official webpage, unpacked it, got into the unpacked folder and did: /home/myusername/.local/bin/python setup.py install --prefix=/home/myusername/.local. However, I get the following error, which is followed by a series of other errors (deriving from this one): gcc -pthread -shared build/temp.linux-x86_64-2.7/numpy/core/blasdot/_dotblas.o -L/usr/local/lib -Lbuild/temp.linux-x86_64-2.7 -lptf77blas -lptcblas -latlas -o build/lib.linux-x86_64-2.7/numpy/core/_dotblas.so /usr/bin/ld: /usr/local/lib/libptcblas.a(cblas_dptgemm.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC Not really knowing what this meant (except that the error apparently has to do with the LAPACK library), I just did the same command as above, but now putting LDFLAGS='-fPIC', as suggested by the error i.e., I did LDFLAGS="-fPIC" /home/myusername/.local/bin/python setup.py install --prefix=/home/myusername/.local. However, I got the same error (except that the prefix -fPIC was addeded after the gcc command above). I tried installing it using pip, i.e., doing /home/myusername/.local/bin/pip install numpy /after successfully instaling pip in my local path). However, I get the exact same error. I searched on the web, but none of the errors seemed to be similar to mine. My first guess is that this has to do with some piece of code that needs root permissions to be executed, or maybe with some problem with the version of the LAPACK libraries or with gcc (gcc version 4.1.2 is installed on the remote computer). Help, anyone?

  • What are the requirements for Windows Remote Assistance over Teredo?

    - by Jens
    I try to get the Windows 7 (or Vista) remote assistance feature to work, without using UPnP on the novices computer. After enabling Teredo on the expert's computer (that is in a corporate network, and therefore has teredo disabled by default), I tried to connect to the novice both using Easy Connect and the invitation file with no success. My triubleshooting included the following (so far). A connection to the novice from my home pc was successful, hinting at a misconfiguration on the experts side. Both computers have a "qualified" connection to the Teredo Server. Both computers have a valid Teredo IP, access to the Global_ PNRP cloud and can resolve names registered with PNRP on the other computer. The expert can resolve the PNRP Id automatically generated with an Easy Connect help request Both computers can ping the other's PNRP name. Both computers can ping the other's Teredo IP Address using ping -6 Now, I am a little stumped. I expected Remote Assistance to work at this point, since my corporate firewall has no Teredo filtering. What could RA cause not to work in this setting? Thanks in advance!

  • Everyone can access my Windows 7 Homegroup file shares - Even Windows XP computers.

    - by adriangrigore
    Hi, I have 3 computers in my network, two running Windows 7 and one running Windows XP. I've set up a homegroup on both Windows 7 computers. Also, all computers are in the same Workgroup. The problem is that one of the Windows 7 computers makes all shares accessible to the entire Workgroup instead of just sharing to the Homegroup as it should be. I created the file share in Windows 7 via right-click in the explorer, then click on "Share For" - "Homegroup (Read/Write)" (translated from German, so the actual wording may be different). Also, when I look at the file sharing properties of that folder, Windows Explorer informs me that Users must have a valid account and password for this Computer to access drive shares. Unfortunately this is not true. Being in the same Workgroup is enough to get access. Homegroup restrictions work as expected on my other Windows 7 computer. When trying to browse those shares from the XP computer, I get a dialog asking for a login and password. What might cause homegroup restrictions to fail and how can I fix this?

  • Best usage for a laptop being used as a desktop without removable batteries

    - by Senseful
    After reading the information on http://batteryuniversity.com, I realize that one of the best ways to permanently damage a lithium ion battery is to use the battery at a high temperature while it's fully charged. This is exactly what happens when you use the computer as if it were a desktop computer, since leaving it plugged in will keep the battery at 100% and using the computer will heat up the battery. This is why it's recommend to remove the battery from your laptop if you are using it is this scenario. My question is what would you do if the laptop doesn't have removable batteries (e.g. a MacBook Pro)? Should I use some kind of charge cycle such as: charge to 80%, unplug the power chord, use the laptop until it reaches 20%, then repeat the cycle by charging to 80% again? If so, which values should I use instead of 80% and 20%? (I think charging to 80% is better than 100% because of the damage that a hot battery at 100% can do, but I just made the figure 80% up, and I'm sure there's a better number to strive for which is backed by science.) I've read many of the articles on batteryuniversity.com, but couldn't find anything pertaining to this. Update: What about doing something like charge (or discharge) it to 50%, then plug it in and turn on settings which use the battery as much as possible (e.g. brightness all the way up, wi-fi on, etc.), in order to try to maintain the battery at 50% (i.e. the rate it is charging is the same as it is discharging). This will probably heat up the battery, but would make it so you don't need to constantly plug and unplug the laptop. The one bad thing is that you are taking up more charge cycles which would decrease the battery life, thus I'm not sure this is a good idea.

  • Windows 8 Pro Homegroup Not Allowing Access to Shared Files

    - by Jack Herr
    I have two pc's and a laptop. With all three running Windows 7, homegroup worked perfectly, with all computers able to access the files on the others exactly as one would expect. I installed Windows 8 Pro, which I downloaded recently from the MSDN website, on the laptop. From the info on the MSDN website, I believe the version downloaded is the official release version, not a release candidate. The install preserved all settings, apps, and files. I cannot connect to the homegroup from the laptop. Well, not exactly. I joined the homegroup during the install, and later left and rejoined, that was advertised as being offered by one of the pc's (not sure why that one was picked and not the other or both). This homegroup appears in my "computer" folder in the file explorer, offering files from that pc. But it excludes documents (only the music, pix, videos, and playlists folders on the one computer appear). I can actually access those files from the laptop. But the Homegroup folder, which actually shows all the computers by account and computer name and includes documents from both computers, does not open those folders when clicked. The computers listed by name in the Network folder give me a login that doesn't work. It asks for a username and password, no combinations of which work. Further, the following error message appears before the login is even attempted: "The system cannot contact a domain controller to service the authentication request. Please try again later." The two windows 7 pc's continue to share all files, including documents, seemlessly. I can also get to the laptop shared files, which I shared during setup, from either pc. Any ideas?

  • Ubuntu - No gnome-panels, no right-click, no internet, no hotkeys

    - by Darthfett
    Hey guys, I've been using Ubuntu (Maverick 10.10) on my desktop (ATI Radeon 5830) for about 3 weeks now, but all of a sudden I am unable to even use my computer. As soon as I start up, I see my desktop, with icons, but I don't see any gnome-panels, and I'm unable to get any options if I right-click. I can start programs by double clicking them. I also cannot get an internet connection. I've tried restarting gnome-panel by killing it, using Ctrl+Alt+5 to switch to a terminal (I don't have a shortcut to one on my desktop, and no hotkeys will work), but no luck. Restarting my computer has no effect upon this (I have to manually cut the power, since I don't know the terminal command). As far as I know, I have not made any changes, and I've never had any problems in the past. This started when I was playing Minecraft, but my internet crapped out, and no amount of re-trying the connection would work. I know it was my computer, as my brother's was working fine in the other room. Any clues as to what's going on? I'm more than willing to troubleshoot.

  • Self-connecting printers

    - by Martin Cerny
    Hello, I work as an administrator in a small company using XP Professional on all computers and two servers with Win 2003 Server. Recently a very unusual problam occured one of the computers keeps connecting to all the printers on the network it doesn't matter if it's an administrator or Domain User as soon as somebody logs in the commputer connects all the printers. The printers are either installed on local computers or on the server and shared. There is no log-on script connecting the printers, I install them manualy and none of the other computers shows such behaviour. We have a printer which is installed on two computers and both of them share it (I'm moving it to Server from a small PC which shared it up to now, but some computers still use the old connection), meaning this specific computer connects to one of the printer two times and it can't use either of the connections. How to prevent this self-connecting to all printers (none of the other computers has this problem). If I delte them from the "Printers" folder everything works fine untill I reconnect and the Folder is once again full of all the printers we have. I solved the smaller problem, computer is now capable of printing on all of the printers (it seems there have been some registry issues), after cleaning the registry and reinstalling the printer it seems to work just fine. But the second thing prevails, the computer connects to all the printers in the network (when I remove one/multiple it is reconnected right after the next log-in by any user).

  • Why we can change our IP address?

    - by iamstupid
    I across some websites that offer change of our IP addresses. It says, we can surf net anonymously, including changing our IP address and location. Most of the softwares are not free, so I have not try it out yet. But my question is, so, IP addresses will no longer be unique or valid for identify which computer were sending/request the information? I though only the ISP can determine our IP, so we can change our IP from some commercial softwares huh? Case: If I change my IP address, I go to a website which is supposed to be banned by my country, will the ISP let me pass the check and I will be able to browse the website which should be blocked? another question: From what I know, if we want to go to certain website, here is the flow: My Computer = ISP = Website = ISP = My computer I am not sure, if its the correct flow, but I am sure that, whichever website I want to visit, I need to go through my ISP, isnt it?. So if we change out IP, our ISP will record our new IP or the original(assigned-by-ISP) IP? Sorry for my bad English.
