  • PowerShell - Finding all of users' group memberships and kicking it out of them

    - by NirPes
    as title says, I have to find all the groups that the user is a member of, and deleting its membership from all of them. I've tried this: get-adgroup -filter * | where {(Get-ADGroupMember $_ | foreach {$_.PrimarySmtpAdress}) -contains "[email protected]"} but it doesnt return anything (although THERE ARE some items that have to be returned) as for the deletion I found no way to do it, could someone give me an example of a code that does this? Im talking about security groups.

  • Can I clone my hard drive to an external and boot from the clone?

    - by willbuntu
    First thing: I am not asking what software I'm supposed to use. I already know the answer: Ghost (proprietary), Clonezilla, and dd (if I'm careful). What I really want to know is if it is possible to (essentially) bit-for-bit clone my entire installation (OS, installed software, activation(s), etc.) to an external USB hard-drive, and then boot off of that (if I need to, I know how to edit BIOS settings and use Plop boot manager), and work with it day-to-day as if there was virtually no difference from using my internal HDD now. Again, I'm not asking how to install Windows to an external (because I know I'd need to do some special workaround), I'm asking if I can clone everything and boot off of it. In case you're wondering why I'm going to this trouble: I'm using a Lenovo Essentials laptop that has an unmodifiable partition table (due to recovery crap), and has all 4 of its partitions spoken for (3 primary, one extended, cannot change the extended). Anyway, my thought is that if I can clone everything and boot off of it when I need to, and just have a Linux distro on the internal HDD, then that could work.

  • Remote Desktop from Linux to Computer that Requires Network Level Authentication

    - by Kyle Brandt
    Is there a way to use rdesktop or another Linux client to connect to a server that requires Network Level Authentication? From Windows Server 2008 R2 -- Control Panel -- System And Security -- System -- Allow Remote Access there is an option that says "Allow connections only from computers running Remote Desktop with Network Level Authentication". So with this enabled I can con not connect from Linux. I can connect from XP but you need SP3 and I had to edit a couple of things in the registry for it to work.

  • Is Ubuntu a viable replacement of Windows XP for small enterprise environments?

    - by Alex. S.
    Hi all, I'm a newbie systems administrator, so any advice would be great. I would like to setup ubuntu 8.04 lts in a small office of consulting in management (around 50 workstations) instead of Windows XP. I would install MS Office 2007 via WINE (*). It would be a fresh installation, so the migration would be less of a pain. The new setup would also include a small server as document repository and a backup server by now. Later, I would install another goodies like a IM server, a document management solution, and whatnot collaborative tool. What do you advice in this scenario? Do you think is viable? Should I try to convince my managers this is a good idea? I consider myself as a fair experienced user in both systems, and I'm the only guy in charge of everything. I need to cut costs down, and I think that antivirus and antimalware software are a waste of money and time. Is this good idea?, or should I resign and try to lock down the Windows systems and install AV software? Is there anything else in this setup I'm not foreseeing? (*) The only catch in my test machine until now had been that Office SmartArt doesn't work properly, the rest of Office 2007 may seem ok.

  • Centos repository packages vs latest developer release

    - by fran
    I have started to run a personal server using CentOS and I have noticed that many packages that are available to install from repository are old compared with the latest release from the developer. I know that installing packages from repository is very easy and I guess that the supplied versions are stable and prepared to work without any trouble, but I still find odd having so much software that lags behind the current version. It's my first time with linux and I don't know what is the "normal" thing, should I stick to whatever version the repository supplies, or try to get the latest from the developer? To be more precisely, the repository supplies the apache httpd web server with version 2.2, I wanted to update to 2.4, so I started removing apache and its dependencies packages that come with centos to use the latest ones, but when I was about to remove pcre v6 to replace it with v8, i found out that 132 installed packages depend on it and probably it is not a good idea to remove it, so that made me think twice about getting the latest software instead of using the packages supplied by the official repositories. Should I leave things as they are instead of going on an upgrade rampage? Thanks

  • SQL Server database on an external hard disk drive

    - by Achilles
    Due to some security problems, My boss has asked me to store all sensitive data in external/removable storages like USB stick or external HDD and this specially includes the MDF/NDF/LDF files of SQL Server 2008 we're running. I've been reading for these last three days with no luck to find a solution. Is there any solution at all? Has ever anybody done such thing?

  • I need to preserve a tape using symantec backup exec. I'm aving trouble doing so

    - by MrVimes
    Please forgive me if this is the wrong stack exchange site. Please suggest which one I should post this to if it is. There's an automatic tape machine running in a remote location, with software (symantec backup exec 11d) Recently one of the servers being backed up had problems with its raid controller, so one of the drives has become invisible. I need to preserve the last good backup of that drive so I am trying to replace the tape with the most recent backup of that drive on it with one of the scratch tapes (blank tapes) present in the machine. I've tried the following... Associate the blank media with the media set in question (Wednesday) For the existing media (the tape with the data I want to keep) I click 'move to vault' and move it to the offline vault. I associate it with something other than 'Wednesday' (a media set called 'keep data infinitely...') I then do an inventory on that slot. The above steps I'm led to believe are supposed to put the fresh tape in the slot that had the tape I want to keep in it. But it just keeps showing up as containing the tape I want to keep after the inventory. (after refreshing the device tree) I am a complete newbie with this software. Can you tell me what I'm doing wrong, and/or tell me how to acheive my desired goal Edit: Just want to point out that I did try to get help directly from symantec with this, but having jumped through countless hoops to create an account and create a support ticket my progress was halted by requiring something called a 'tecnical contact id' at the final step with no explanation of what it is or how to get one.

  • Best way to segment traffic, Vlan or subnet

    - by thebird
    We have a medium sized network of around 200 nodes and are currently in the process of replacing old daisy chained switches with stack-able or chassis style switches. Right now our network is broken up via subnet; production, management, IP, etc each on a separate subnet. Does anyone have an opinion on whether creating Vlan's instead of subnets would be more beneficial? Our general goal is to prevent bottlenecks, separate traffic for security, and to manage traffic with more ease.

  • Can I limit remote desktop to a particular network card?

    - by Jack Mills
    I have two routers/internet connections connected to my PC. One is a slower connection with a fixed IP that I use for business, the other is a faster connection I use for day to day surfing. I have to use the fixed IP connection to log onto certain servers (due to security) to work but I'm finding that often my PC will try to use my other internet connection to connect which will get rejected (as it doesn't have the fixed IP). Can I limit remote desktop to use a particular network card to get around this problem. Note: I'm running Windows 7

  • Win7 Hangs During App Install/Upgrade/Uninstall

    - by JadeMason
    I have a custom built PC that intermittently hangs when installing, uninstalling, or upgrading applications. Technical Specs ASUS P5E w/ WiFi Motherboard Intel Core2 Quad Q6600 Processor 4x 2GB G.Skill DDR2 800 SDRAM ASUS EAH2900XT / Radeon HD 2900XT 512MB Video Card Under normal operation the machine runs reliably, even under heavy load, such as video transcoding. The temperature never gets anywhere near where I would worry about it. However, the machine regularly hangs (complete lockup, no response to keyboard or mouse, no activity on-screen) when either installing a new application, uninstalling an existing application, or applying patches to existing applications or the OS. This is extremely frustrating as this machine is primarily used as a HTPC. Several apps are configured for automatic updates, and these updates sometimes cause the machine to lockup while we are watching content on the PC. In previously investigating this issue, I found one likely problem could be my Logitech Webcam. The Logitech software has a bug that leaves an entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\SessionManager\PendingFileRenameOperations Which references the Temp directory. My registry contained this error, so I uninstalled the webcam software and deleted this registry key value. Unfortunately, the machine will still intermittently hang. I've noticed that the hangs always happen when an install/upgrade/uninstall requires elevated privileges (presumably to modify the registry). I can typically get at least one install/upgrade/uninstall to complete after a reboot, but after that it is a game of russian roulette to see if the operation will succeed or hang the machine. The event log is not helpful, as log messages end at the time of the hang, with no record of a warning or error. My only recourse when the machine hangs in this way is to perform a hard reset/power cycle. Any tips on how to further debug this issue are greatly appreciated.

  • How to handle many daily emails from cron efficiently?

    - by drumfire
    With each new server comes at least one more daily crontab email. The FreeBSD servers even send two: a daily and a security run output. Thanks to my obsession with virtualisation the number of emails I need to read (and then often discard without further action) is becoming too much. What ways are there to manage / automate this process? Can emails be replaced by something that is web based? Surely some of you must have found creative ways for this.

  • How to combine AWS and dedicated external servers?

    - by rfw21
    I have an extensive network of servers all currently hosted on AWS EC2. For reasons of cost I plan to gradually migrate to dedicated servers where possible. So: How can I best combine AWS and non-AWS servers in my network? Ideally, I should be able to assign internal IP addresses to the external servers, include them in AWS security groups and ensure that all private traffic between my AWS servers and external servers is secure.

  • FTP Server upload and filesystem questions

    - by Alex
    I'm a photographer who mainly does event photography. A while ago I bought myself a Nikon WT-4 wireless transmitter, a small device which connects via USB to my Nikon D700 DSLR, and then establishes a WiFi connection to an existing WLAN. It can then upload any pictures I take via FTP to an FTP server somewhere in the network. On my laptop I then have a piece of software which will check a given folder on the disk regularly, this software is smart enough to look at the modified file timestamp, if this timestamp is less than 10 seconds ago, it will not attempt to import the folder and skip the file in this iteration of the import scan. The problem I've discovered seems to be inherent to the FTP protocol, as I have the same problem with Windows 7 built in IIS server, as I do with FileZilla FTP server. When the transmitter starts to upload a file, the FTP server will create a small 300-500 KB file with the correct filename on the disk, but then do nothing with the file until it has completely received the file via FTP. So it seems to create this small dummy file, and then buffer the remainder of the FTP upload until it's finished, and then dump the rest of the file into the dummy file making it the correct size. Problem is, these uploads take about 15-30 seconds depending on reception, but since the folder watch tool will already try to import any file older than 10 seconds, it will always try to import the small dummy files which obviously fails as they're not copmlete yet. Is there any way to 'disable' this behaviour? Ideally I would like my file only to show up once it's been completely uploaded. Or perhaps someone knows another FTP server application (it has to run on win7) which does not show this behaviour?

  • Photoshop CS5 performance over network drive (cifs)

    - by grub
    Hello Everyone I did install a QNAP NAS TS410 for a customer (professional photographer) with 3 Hitachi Deskstar 7200rpm 2TB disk configured as RAID5. The NAS and the workstations are connected over a Gigabit network. He and his co-worker are accessing the photos (about 1TB of photos) over a mapped network drive from their windows machines (Windows XP - 32bit and Windows 7 Ultimate - 32bit). Both are using Photoshop CS5 to edit the photos. The problem is that to save a edited photo takes a really long time, it takes about 3 times as long to save a photo as to open it. After some tests I can exclude the network, the NAS and the windows machines as source of the issue. I think the problem is the Photoshop software and its handling of the network drives. Officially network drives are not supported by Adobe. I do not have any experience with the Adobe products, especially with Adobe Photoshop CS5. What are your recommendation to solve the performance issue? Should my customer copy the photos to the local drive, edit them and upload them again to the network drive or is Adobe Drive or Adobe Version Cue the answer? One requirement is that the photos need to be accessible / editable from both computers even when one of them is offline. Adobe Version Cue needs a dedicated service running to be usable, so this solution is not possible as far as I understand the Cue software. Thank you for your input to this issue and have a nice day :-) Greetings grub
