  • Why does my computer slow down so much when attaching Bluetooth dongle?

    - by Jeff Yates
    I have a Bluetooth dongle and I plugged it into my work laptop (a Dell Latitude D830). Windows detects the Generic Bluetooth USB or similar and then proceeds to go incredibly slow with a process, avp.exe¹, taking 50% CPU. The System Idle process is getting most of the other 50% CPU and the avp.exe process is only at Normal priority. The machine doesn't seem to recover, so I had to turn the power off and reboot. Now, I haven't installed the drivers yet for the device, which I am doing now and I expect it to resolve the problem, so I am not asking how to fix this. I would rather know why Windows goes so slow in the first place. What is it trying to do and failing at so badly that it barely crawls? ¹ Part of Kaspersky Internet Security suite

  • Recycle remote IIS app pool from the command line?

    - by Ken
    Is it possible to recycle an IIS7 app pool from the command line, on a different machine? I've found APPCMD (appcmd recycle apppool my-app-pool), but it only operates on the host it's run on, AFAICT. I heard a rumor there might be a way to do it with Powershell, but I know nothing about that, and I'm apparently not very good at googling for it. I'm using Vista / Server 2008, if that matters. EDIT: I found something called WinRM that somebody claims is able to run APPCMD itself, but I'm not sure exactly how, yet.

  • Can computer crashes and reboots mean weak power supply?

    - by TomA
    Recently I replaced the videocard in my PC for a newer, faster one. All games work perfectly but I get random system crashes and reboots. This happens even when the system is almost idle (browsing, playing music). It never happened with the old card. All drivers are up-to-date. Is it possible that the power supply is not powerful enough for the new card?

  • Are newly installed fonts in an email going to be displayed properly on another computer?

    - by Mehper C. Palavuzlar
    I have downloaded and installed a new font family (Gentium) on my machine. I want to use this font in some of my email correspondences. When I compose an email in Outlook 2007 with these fonts and send it to someone, is he going to be able to display it properly (I mean, with the same fonts, just the same as I can see the email)? I'm assuming the addressee doesn't have this font family installed on his machine. Does it matter if the addressee uses Outlook or a web-based email?

  • Is computer's DRAM size not as important once we get a Solid State Drive?

    - by Jian Lin
    I am thinking of getting a Dell X11 netbook, and it can go up to 8GB of DRAM, together with a 256GB Solid State Drive. So in that case, it can handle quite a bit of Virtual PC running Linux, and Win XP, etc. But is the 8GB of RAM not so important any more. Won't 2GB or 4GB be quite good if a Solid State Hard drive is used? I think the most worried thing is that the memory is not enough and the less often used data is swapped to the pagefile on hard disk and it will become really slow, but with SDD drive, the problem is a lot less of a concerned? Is there a comparison as to, if DRAM speed is n, then SDD drive speed is how many n and hard disk speed is how many n just as a ball park comparison?

  • Set up a proxy on a remote Linux server?

    - by Isaac Waller
    In order to watch Hulu and other sites which are not available in my region (Canada). I would like to set up my own proxy server in the USA on a Linode for my Macbook running Mac OS X. On my Macbook, I would like to set up the proxy server in the OS, instead of the browser so all apps use it. I believe Mac OS X supports HTTP and SOCKS proxies. What type of proxy should I use, and what server software should I use on the Linux machine?

  • How to get two seperate remote domain controllers with same IP to work?

    - by Mr. Mister
    Hi, I have a VPN setup between multiple locations. Between each location and the central point (me), is a trust between our domain controllers. It all works great.. A new location wants to join, but their AD controller is using an IP address that is already in use by another AD in a separate location. Neither locations can change their IP addresses, but apparently there is a NAT rule that could be used to allow communication between each AD controller? The central site has a Cisco 5510 firewall which could perform the NAT, but I am unsure of the logic behind the NAT rule. Is anyone able to explain or help out? Thanks.

  • How to prevent remote hosts from delivering mail to Postfix with spoofed From header?

    - by Hongli Lai
    I have a host, let's call it foo.com, on which I'm running Postfix on Debian. Postfix is currently configured to do these things: All mail with @foo.com as recipient is handled by this Postfix server. It forwards all such mail to my Gmail account. The firewall thus allows port 25. All mail with another domain as recipient is rejected. SPF records have been set up for the foo.com domain, saying that foo.com is the sole origin of all mail from @foo.com. Applications running on foo.com can connect to localhost:25 to deliver mail, with [email protected] as sender. However I recently noticed that some spammers are able to send spam to me while passing the SPF checks. Upon further inspection, it looks like they connect to my Postfix server and then say HELO bar.com MAIL FROM:<[email protected]> <---- this! RCPT TO:<[email protected]> DATA From: "Buy Viagra" <[email protected]> <--- and this! ... How do I prevent this? I only want applications running on localhost to be able to say MAIL FROM:<[email protected]>. Here's my current config (main.cf): https://gist.github.com/1283647

  • Can I build or test a computer without a case?

    - by jasondavis
    I am in the process of building a really nice new PC right now. It's going to have a nice Lian Li case with the internals powder coated black and all the wires will be sleeved. So my problem is I am getting parts in a couple days but my case will not be completed for about a month because it is on back order plus time to powder coat it. I am purchasing many of m y parts from newegg.com and they claim you must return any dead parts within 30 days or the invoice for there warranty to replace bad parts. So is it possible for me to set up the PC without a case just to test that the main parts are working correctly within the timeframe I am allowed? If this is possible, how do I deal with turning the system on/off without a powere button? Or is therer one on a motherboard? Thanks for any tips/advice

  • How do I use an SSH public key from a remote machine?

    - by kubi
    Setup The public keys are set up on a Macbook. I can do a passwordless push to github and a server (iMac) on the local network. The Problem I know the keys are partially setup correctly, because I everything works if I'm sitting at the Macbook. What doesn't work is when I SSH into the Macbook remotely and attempt to push to github or to the iMac server. I'm prompted to input my SSH key passphrase. What am I missing to enable pushing to github from the Macbook while logged in remotely from the iMac?

  • sshfs too slow while remote editing on Eclipse and other IDEs, what options to use to make it faster. *Not* for mac users

    - by Fullmooninu
    I've been looking into this problem, and it is common. But since there is a package for Mac with the same name, the solution for Mac users is hiding the solution for Linux users and our default sshfs. This the best I got so far, from what actually works on Linux. sshfs user@host:remoteDir localDir -o Ciphers=arcfour -oauto_cache,reconnect,no_readahead note: this question was not appropriate for stackoverflow, dunno why: http://stackoverflow.com/questions/25365487/sshfs-too-slow-what-options-to-use-to-make-it-faster-not-for-mac-users

  • My computer is listed twice in the Network view; network shares are not accessible

    - by romkyns
    I have a couple of network shares set up on my Win7 machine. They've been in constant use, from that same machine on which they're set up. One morning they just randomly stopped working: When I went looking for what was wrong, I noticed that I also had my PC listed twice in the Network view in Explorer: "Sirius" is the name of the PC on which these screenshots were taken. I may have installed some windows updates around the time this happened. I have since tried rebooting and installing all the latest updates, to no avail. I've also removed the share in question and re-added it, making sure I give all rights to everyone. I'm an administrator on this machine, but I can't access the administrative shares (\\SIRIUS\c$) either, with the same message. I can access \\localhost\AcronisImages and \\localhost\c$, and I can ping sirius. Any ideas?

  • My internet drops and will only reconnect if I troubleshoot it or restart my computer.

    - by Paul
    My internet loses its connection and at the same time, and my speaker seems broken if that happens and my mouse will not be smooth as it was before it happens. It already happened before and I didnt mind it. But now, it's happening literally all the time. After startup, my connection seems okay but after some few minutes, even without me doing something, my laptop will just lose its connection. It says that it is not connected and connections are available, but if I check if there are connections where I can connect it shows nothing. Even if, there is actually a wi-fi connection where my phone and other laptops connect. They dont seem to have problem with it. Just my laptop. After that happens, I usually restart my laptop but I discovered that troubleshooting it would somehow repair the problem, but not all the time. It says that restarting my wireless adapter do the job. Are there any long term fix? I mean that could last long or totally erase the problem? I have Atheros AR5B97 Wireless Network Adapter and Microsoft Virtual WiFi Miniport Adapter, both enabled. On the services, I have Wired AutoConfig and WLAN AutoConfig on Automatic. Aspire 4750, Windows 7 (x86)
