  • Laptop is super slow on network

    - by Gary
    So on our network we have a bunch of wireless macs and window Operating laptops, we have a network setup with 802.11g,b,n. All the laptops seem fine except one which is only getting speeds of 54Mb. I have changed the encryption from AES to TKIP and reset the connection, i have updated the drivers, tried plugging it into the LAN and still same slow speed. Apparently the laptop with the slow speed is fine on other networks. I don't know what to do, can anyone help me?

  • Why can't I create a Windows backup on my secondary disk?

    - by Brian Sullivan
    I've installed Windows 7 Ultimate on an SSD that I've added to the XPS desktop that I bought from Dell. I would like to use the built-in backup functionality to create incremental backups and store them on the large drive that came with the machine. I formatted the large drive and turned it into a Basic disk. However, when I try to set the backup location to the large internal disk (E:\) in the "Set up backup" wizard, a get a message saying, "A system image cannot be saved on a drive that your computer boots from or that Windows is installed on." Windows is not installed on that disk. I even deleted the OEM partition that was on the disk, and removed it completely from the boot order in the BIOS. Any clue why Windows is griping at me about this?

  • Jumbo Frames, ISCSI and ESXi

    - by vlannoob
    I have enabled Jumbo Frames (9000) in ESXi for all my vmNICs, vmKernels, vSwitches, iSCSI Bindings etc - basically anywhere in ESXi where it has an MTU settings I have put 9000 in it. The ports on the switches (Dell PowerConnects) are all set for Jumbo Frames. I have a Dell MD3200i with 2 controllers, each with 4 ports for iSCSI. Each of these ports is set to Jumbo Frames (9000) as well. So now the questions: Do I need to log into each Windows Server VM I am running and delve into the NIC properties and manually set it to Jumbo Frames in the NIC properties in the device Manager as well? Whats the best way of testing that Jumbo Frames are indeed working as intended?

  • Why such a dramatic difference in wireless router max. simultaneous connections?

    - by Jez
    Recently, I've needed to look into buying a wireless router for a mission-critical system at work that will need to support quite a few simultaneous connections (potentially a few hundred laptops). One thing I've noticed is that there seems to be a dramatic difference between the max. simultaneous connections different routers can support; see this page for example - anything from 32 to 35,000! Why is there this degree of difference? You'd have thought that if we know how to make routers that can handle thousands of connections, we wouldn't be making stuff that's limited to a pathetic 32 anymore. Is it a firmware thing? A hardware thing? Are low-end manufacturers purposely putting low arbitrary connection limits in so people can be "encouraged" to pay more for high-end routers?

  • Can someone implement LVM on an existing single-hard disk system ?

    - by jfmessier
    I am using SuSE Linux (10) and I am considering expanding the available disk, without resizing an existing partition (which is not easy to do on a VM). Instead, I want to create another virtual disk, and add it in a new LVM volume, which would include the existing disk, and this new one, in a seamless single mount point. We are using VMware vServer 4, under Lab Manager and Virtual Centre. Does SuSE support LVM in version 10 ? Thanks :-)

  • Intel Core 2 Duo E6600 versus AMD Athlon II X2 3GHZ

    - by Billy ONeal
    Hello :) I have an Intel Core 2 Duo E6600 (2.4GHZ) in my current desktop, and I have a newer machine with an AMD Athlon II X2 3.0GHZ. I'm wondering how the systems will perform in comparison to one another. I'd like to use the AMD because it's 45nm and uses less power, but I don't want to do so at a loss in perforamnce. Which should perform better? Billy3

  • What is the computer "doing" when it is running slow and task manager is not showing any CPU activity?

    - by Joakim Tall
    Typical example is when shutting down a memoryintensive application. It can take quite a while before the computer gets back up to speed. Is there some inherent cost in releasing memory? Or is it throttled by some kind of harddrive activity, and if so is there any good way to track that? I usually bring up task manager when a computer is running slow, and usually sorting by cpu activity can show what process is causing the problem, but sometimes there is no activity showing. And yes I "show processes from all users", I have been wondering this since the days win2k :)

  • sys.dm_exec_query_stats interaction with recompilation

    - by Sam Saffron
    We use sys.dm_exec_query_stats to track down slow queries and queries that are IO offenders. This works great, we get a lot of very insightful stats. It is clear this is not as accurate as running a profiler trace, as you have no idea when SQL Server will decide to chuck out a an execution plan. We have quite a few queries where the wrong execution plan is cached. For example queries like the following: SELECT TOP 30 a.Id FROM Posts a JOIN Posts q ON q.Id = a.ParentId JOIN PostTags pt ON q.Id = pt.PostId WHERE a.PostTypeId = 2 AND a.DeletionDate IS NULL AND a.CommunityOwnedDate IS NULL AND a.CreationDate @date AND LEN(a.Body) 300 AND pt.Tag = @tag AND a.Score 0 ORDER BY a.Score DESC The problem is that the ideal plan really depends on the date selected (screenshot of ideal plan): However if the wrong plan is cached, it totally chokes when the date range is big: (notice the big fat lines) To overcome this we were recommended to use either OPTION (OPTIMIZE FOR UNKNOWN) or OPTION (RECOMPILE) OPTIMIZE FOR UNKNOWN results in a slightly better plan, which is far from optimal. Executions are tracked in sys.dm_exec_query_stats. RECOMPILE results in the best plan being chosen, however no execution counts and stats are tracked in sys.dm_exec_query_stats. Is there another DMV we could use to track stats on queries with OPTION (RECOMPILE)? Is this behavior by-design? Is there another way we can for recompilation while keeping stats tracked in sys.dm_exec_query_stats? Note: the framework will always execute parameterized queries using sp_executesql

  • SQL Server Full Text Search resource consumption

    - by Sam Saffron
    When SQL Server builds a fulltext index computer resources are consumed (IO/Memory/CPU) Similarly when you perform full text searches, resources are consumed. How can I get a gauge over a 24 hour period of the exact amount of CPU and IO(reads/writes) that fulltext is responsible for, in relation to global SQL Server resource usage. Are there any perfmon counters, DMVs or profiler traces I can use to help answer this question?

  • Windows XP: Slow start menu 'All Programs' response

    - by user17381
    When I click start, and then 'All Programs' (or select a sub menu of all programs) I get a grey menu which does not respond for about 5 seconds - after this it is ok. Any idea what is causing the menu to behave sluggishly? What can be done to fix this? Thanks Info Requested System Specs : Core2 T5500 @1.66GHz, 2GB Ram Windows version: XP Professional SP2 Happens Every time I click the menu (not just first time), has gradually been getting worse. Nothing too unusual at startup: ComodoFirewall, AVG AV, Truecrypt (only for small volume). AV Software: AVG.

  • Recommended drive encryption solution

    - by Chris Driver
    Hello, I will soon be purchasing a number of laptops running Windows 7 for our mobile staff. Due to the nature of our business I will need drive encryption. Windows BitLocker seems the obvious choice, but it looks like I need to purchase either Windows 7 Enterprise or Ultimate editions to get it. Can anyone offer suggestions on the best course of action: a) Use BitLocker, bite the bullet and pay to upgrade to Enterprise/Ultimate b) Pay for another 3rd party drive encryption product that is cheaper (suggestions appreciated) c) Use a free drive encryption product such as TrueCrypt Ideally I am also interested in 'real world' experience from people who are using drive encryption software and any pitfalls to look out for. Many thanks in advance... UPDATE Decided to go with TrueCrypt for the following reasons: a) The product has a good track record b) I am not managing a large quantity of laptops so integration with Active Directory, Management consoles etc is not a huge benefit c) Although eks did make a good point about Evil Maid (EM) attacks, our data is not that desirable to consider it a major factor d) The cost (free) is a big plus but not the primary motivator The next problem I face is imaging (Acronis/Ghost/..) encrypted drives will not work unless I perform sector-by-sector imaging. That means an 80Gb encrypted partition creates an 80Gb image file :(

  • Removing orphan vmware images

    - by Brad Bruce
    I am trying to remove some VMWare images that were created by a machine that is no longer available. We do not plan to use VMWare and would like to clear up the space. I get a message Cannot delete [filename]... for all of the files in these directories. Can anyone tell me how to delete them (short of reformatting)? Thanks

  • Is it possible to FORMAT an external hard disk that has been encrypted using Storagecrypt?

    - by Pandian John
    Basically the big problem is that about 680 GB of data from my Seagate 2 TB Ext HD is lost because I was experimenting with a software called storagecrypt. I used it a few months ago and today I tried it again but i didn't know that the old password is already set in the hard disk when I pressed the encrypt button. I forgot the password which is disappointing. Not to mention that software uses 128 bit AES encryption so there is no way iam going to recover that data. My question is that is it possible to Format my Hard disk which has been encrypted? What i mean is that is it possible to completely wipe the data just like it is newly bought so that I can use my External Hard disk?( I tried to format by right click-- Format. But the size of the disk is shown as 1 MB. Answers would be very much appreciated. Thanks.

  • How dow I remove 1.000.000 WebsiteCache directories?

    - by harper
    I found that in a WebsiteCache directory more than 1.000.000 subdirectories has been created. I want to remove all these directories. My first approach was to use the command line tool: cd WebsiteCache rmdir /Q /S . This will remove all subdirectories except WebsiteCache itself, since it is the current working directory. I noticed after two hours that the directoriws starting with A-H have been removed. Why does rmdir removes the directories in alphabetical order? It must take additional effort to do this ordered. What is a fast way to deleted such an amount of directories?

  • CPU and HD degradation on sourced based Linux distribution

    - by danilo2
    I was wondering for a long time if source based Linux distributions, like Gentoo or Funtoo are "destroying" your system faster than binary ones (like Fedora or Debian). I'm talking about CPU and hard drive degradation. Of course, when you're updating your system, it has to compile everything from source, so it takes longer and your CPU is used at hard conditions (it is warmer and more loaded). Such systems compile hundreds of packages weekly, so does it really matter? Does such a system degrade faster than binary based ones?

  • Soundtest works, but no other sounds and windows starts very slowly

    - by Kristian Kari
    So suddenly all sounds on my computer stopped working expect the sound test works, but when I go to control panel and audio it says there's no audio device. And audio players and audio on website doesn't work either. and Also windows starts very slowly. I'm not sure if this helps but I'll tell what happened before this. I downloaded this program from a little shady website, I hesitated and for a good reason I guess cos the moment I finished downloading it, my antivir detected it as unwanted program and put it on quarantine. I thought everything was fine, but had some problems with program (won't go to details about it cos it's not really related to audio) so rebooted the computer and I was suprised that windows started really really slowly. It took like 5 mins to load the desktop such. After that I noticed the sounds were missing, I immediately deleted the program since I thought it was causing the problem. But it didn't change much. I tried to find the solution with no success and now I'm just scanning again my computer. I'd be thankful if anyone would be able to help me. I might have left a thing or ten things out, so feel free to ask. oh and I'm using windows xp

  • Why doesn't Windows XP show "Total Size" and "Free Space" for USB flash disks?

    - by Mehper C. Palavuzlar
    When I double click on My Computer, I can immediately see the Total size and Free space for internal and external HDDs, and inserted CD/DVD media, but in the same columns I cannot see these values for any USB flash drives. They are just empty. To see, I have to right click on USB drive letter, and select Properties. Is there a trick to make Windows XP display USB drive's Total size and Free space in My Computer window?

  • How to calculate required switch speed based on network usage?

    - by tobefound
    I have a 48 port HP Procurve Switch 2610 (J9088A) that can handle 13.0 million PPS (packets per second) and features wire speed switching capacity at 17.6Gbps. First off, what does that REALLY mean? Where do I start when trying to figure out if my office (with 70 employees) will be well setup with this switch? How to calculate through-put based on a user average load of X MB per day? 90% of the folks will only be sending email, access random websites, etc... the other 10% will be conducting heavier tasks like moving image files (10 MB) across network shares, constant external FTP streams through the switch to a server etc... Is this switch good enough?

  • RAID 6 that can read with least 1000 Mbit/s?

    - by Diblo Dk
    I purchased a Dell PERC 6/i which I expected to be able to read with 1000 Mbps. There is not much to do now, but there are some things I wanted knowledge about for another time. I have configured it with four 2 TByte drives and RAID 6. It have 256 MByt ram and transfer rate of 300 Mbps. The benchmark test showed: Min read rate: 136.3 Mbps Max read rate: 329,6 Mbps Avg read rate: 242,2 Mbps What could I had done to get at least 1000 Mbps? Is it normal for internal and external RAID controllers to have a lower transfer rate eg. 300 Mbps? (I did not noticed at the time that it was not 3 Gbps) How would a RAID 10 had performed compared to RAID 6 or 5? Would it have been better to use software RAID (Linux) with the internal 3 Gbps SATA controller? UPDATE: The drives is SATA III 6 Gbps. http://www.seagate.com/files/staticfiles/docs/pdf/datasheet/disc/desktop-hdd-data-sheet-ds1770-1-1212us.pdf (2TB)

  • Microsoft Mouse and Keyboard Center - Slow response for App-specific shortcuts

    - by Darrel Hoffman
    So a few months ago, I bought a new MS mouse, and was surprised that they'd discontinued Intellipoint in favor of this Microsoft Mouse and Keyboard Center. It seems to have the same functionality underneath all the bloat, but there's a very serious drawback - when I set up application-specific functions for the extra buttons on the mouse, they work, but sometimes with a very long delay, like up to a minute or more. For example, I often set up the left side button as an "Undo" in various programs for convenience. But sometimes, when I try to use that Undo button, nothing happens, so I'm forced to use the standard Ctrl-Z or whatever. But then, a minute or so later, it suddenly remembers that I hit that button a while back, and calls the Undo unexpectedly on something entirely different. It's infuriating. No modern computer function should be this slow. It's not the software or the computer itself, because doing an Undo via Ctrl-Z or the menu still works instantly. It's very definitely a side-effect of delayed response to the mouse button. Usually after it delays the first time, it'll work quickly after that, but if you haven't used a given shortcut in several minutes, it "forgets" again and you get another inexplicably long delay. Intellipoint never had this problem, but it's not supported any more, and not compatible with the newer mice. Has anyone else noticed slow-downs with MS M&K C and app-specific shortcuts? Any ideas how to get around this? I use these shortcuts extensively in my workflow and it's just entirely unacceptable to have such a long delay in what should be a pretty basic feature.

  • How do you passthrough native SATA drives to a guest on ESXi?

    - by John
    I have ESXi 4.0 running on an Intel DX58S0 Mothboardboard with an Intel Core i7 930 processor. VT-d is also enabled. I have three drives in the system, drive 0 is used for ESXi. Drive 1 and 2 contain data from an older machine and show up under the "Storage Adapters" section in configuration. I would like to allow a guest machine to access the data on these drives (as nativly as possible). I have enabled passthrough of the motherboard's built in SATA controller (Intel/Marvell 88SE6121 ). This controller shows up in my guest OS, but the guest shows no drives aside from the normal virtual drive. I have tried a Linux guest and Windows7. I have also configured the host machine to try IDE/RAID/ACHI modes for the SATA controller. Any ideas how I can configure one of my guests to get at the raw data on these drives?
