• Why am I not able to create a backup plan for TFS?

  - by noocyte

  I am trying to create a backup plan using the TFS Power Tools but I keep running into this error message: I have checked that the account has Full Control on the share, I can edit, create and delete files there.

• Can't Connect SQL server - process being used by another process. Conflict with IIS?

  - by shinya

  I'm having problem connecting to MS SQL Server (2012 Express) after accessing a database through IIS (web site). I can access the data through web site no problem, but I can't access the data from any other programs (i.e SSMS) until I reboot the SQL server. It seems that the connection stays open even if I close a browser. Here is error message I'm getting Unable to open the physical file "C:---------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Unable to open the physical file "C:-------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Cannot open user default database. Login failed. Login failed for user 'Myserver\myname'. (.Net SqlClient Data Provider) Server Name: MYPC\SQLEXPRESS Error Number: 5120 Severity: 16 State: 101 Line Number: 65536 I follow the help link and it told me to move TCP before named pipes in the protocol order list. I tried it but it didn't help at all. What is the proper settings on SQL server or IIS in order to release process after closing a browser. How do I avoid getting this error? Thank you for your help

• Second monitor stopped being recognized by Windows

  - by Eric J.

  One of the developer PC's running Windows Vista Ultimate had the second monitor stop being recognized in Windows overnight. There were no hardware or driver changes at the time, though I have subsequently updated to the latest nVidia drivers (card is NVIDIA GeForce 210). The non-recognized monitor IS recognized during the boot sequence. In fact, only the "bad" one shows the POST or the Windows loading screen. At some point during Windows initialization after the loading screen disappears and before the logon screen appears, the active monitor switches. Any thoughts? UPDATE: When I open the Vista monitor properties window, I see my primary display and secondary display depicted. The primary one is portrayed as the regular blue box, but the secondary one is portrayed greyed-out. I have the option to "Extend desktop to this monitor", the only resolution is 800x600, and all of the advanced monitor properties are greyed out as well. If I opt to extend the desktop, the greyed-out box turns blue, when I then select Apply the screens flash as usual and I'm given the 15 second countdown to accept the new settings and when I do, everything returns to the previously broken state... secondary monitor is portrayed greyed-out again. At no point is the desktop shown on the secondary monitor.

• How to send from my Z88 to my PC

  - by Bevan

  I've got a Cambridge Z88 that I want to get working with my PC. Around 6 years ago - in 2004 - I made heavy use of my Z88 to do a whole bunch of writing on the train while commuting to and from work. The Z88 is solid state, lightweight and has a full size silent keyboard, so it works very well as a writing instrument. I still have the serial cable I soldered up back then and used successfully in 2004. It has these connections: Z88 9 pin ----- ------- 2 TxD ------> RxD 2 3 RxD <------ TxD 3 7 GND <-----> GND 5 4 RTS ------> CTS 8 5 CTS <-+ RTS 7 8 DCD <-+---- DTR 4 9 DTR ----+-> DCD 1 +-> DSR 6 Unfortunately, I haven't been able to find my notes from 2004 that describe how I got it to work back then. I've spent several hours trying to Google a result, but to no avail. I'm pretty sure the cable is fine - after all, it's what I used successfully six years ago, and I've checked it out with a multimeter - so I'm focusing on the PC end of things, which is where I'd like some assistance. Q1: In my recent attempts, I've been using both Hyperterminal (as built into Windows XP) and the command line (copy com2: con:), but with no success. What's a good (better!) serial communications application to use? Is there one that allows me to see as deep as the signalling that's occurring on the wire? Q2: If you have a Z88 that works correctly with your PC, what software do you use on the PC end, and what's the pinout of your cable? I'm pretty sure that the Z88 itself is working properly: When using the built in Import/Export tool to send a file, I see different behaviour when my serial cable is connected compared to disconnected. When disconnected, the transmission appears to work, with a progress meter counting up and then finishing; when connected, nothing happens 'cept a timeout if I wait long enough.

• Hung Java JVM failing to respond to kill -3

  - by Hans

  I have a Java VM that is hanging "randomly". I quote the randomly bit, because there is obviously a reason that the VM is hanging, but the hang does not occur periodically. We have the same software running in different customer environments and in those environments the JVM is not hanging. In the process of attempting to troubleshoot the hang the process exists with zero CPU utilization. I then attempt to execute kill -3 and the kill command hangs. No JVM Thread Dump is produced. I have spent time instrumenting the code to periodically log the thread stack traces hoping to catch the JVM in a state that would indicate where the issue lies, but so far this attempt has not born much fruit. Unfortunately I have not been able to reproduce this issue in my lab environment so I am limited by what can be done at the Customer site. The OS's in question are Red Hat Enterprise 5.4 and SUSE 10 running java version 1.6.0_05-b13 Has anyone had this problem? Any ideas on why kill -3 is failing to produce a Java Thread Dump? Thanks!

• Adobe Reader XI doesn't allow the editing of fields in a document after it's been edited?

  - by leeand00

  One of the users at our company has a *.pdf file she received from the state of Pennsylvania. The version of Adobe Reader she is using is Adobe Reader XI 11.0.3. She uses this pdf file to send in a report. Her workflow goes like this: She makes a copy of the file. She opens the file and the file displays in purple at the top: Please fill out the following form. You can save data typed into this form. Highlight Existing Fields She fills in the specifics by entering values into the form fields. A few weeks later she returns to the same pdf document and can no longer edit the fields, instead she gets the following message: "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document." She's also running Windows 7 and I've been told that the issue was once fixed by setting compatibility mode on Adobe Reader XI to Windows XP SP3.

• Recovering ZFS pool with errors on import.

  - by Sqeaky

  I have a machine that had some trouble with some bad RAM. After I diagnosed it and removed the offending stick of RAM, The ZFS pool in the machine was trying to access drives by using incorrect device names. I simply exported the pool and re-imported it to correct this. However I am now getting this error. The pool Storage no longer automatically mounts sqeaky@sqeaky-media-server:/$ sudo zpool status no pools available A regular import says its corrupt sqeaky@sqeaky-media-server:/$ sudo zpool import pool: Storage id: 13247750448079582452 state: UNAVAIL status: The pool is formatted using an older on-disk version. action: The pool cannot be imported due to damaged devices or data. config: Storage UNAVAIL insufficient replicas raidz1 UNAVAIL corrupted data 805066522130738790 ONLINE sdd3 ONLINE sda3 ONLINE sdc ONLINE A specific import says the vdev configuration is invalid sqeaky@sqeaky-media-server:/$ sudo zpool import Storage cannot import 'Storage': invalid vdev configuration I should have 4 devices in my ZFS pool: /dev/sda3 /dev/sdd3 /dev/sdc /dev/sdb I have no clue what 805066522130738790 is but I plan on investigating further. I am also trying to figure out how to use zdb to get more information about what the pool thinks is going on. For reference This was setup this way, because at the time this machine/pool was setup it needed certain Linux features and booting from ZFS wasn't yet supported in Linux. The partitions sda1 and sdd1 are in a raid 1 for the operating system and sdd2 and sda2 are in a raid1 for the swap. Any clue on how to recover this ZFS pool?

• Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

  - by Maxim Zaslavsky

  I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

• How can I use my cell phone to establish a dial-up networking connection?

  - by gWiz

  I am using Windows 7 and have a BlackBerry with T-Mobile (U.S.). I have paired the phone with my computer over Bluetooth, which automatically creates a serial port for it. I am able to open the port in PuTTY and successfully issue AT commands to the modem, including dialing. However, while using Windows to create and establish a Dial-Up Networking connection, I get an error dialog stating "Error 678. The remote computer did not respond." In my testing, I also tried setting up a connection to dial a number connected to a phone. When attempting to connect over this connection, the phone does ring but the very moment I answer the call, my computer displays the above error dialog. What must be done to successfully establish such a PPP connection? Some special AT initialization string perhaps? To clarify, I'm not referring to the well-described and popular technique known as "tethering," in which the remote host of the data link is the mobile service provider. I am interested specifically in establishing direct data links with remote hosts other than my mobile service provider. Think old-school landline connection to your friend's computer or BBS. Edit 1 As grawity pointed out in comments, the missing piece of the puzzle is the actual modulator that is compatible with v-series protocols, which I expected to be built into the cellphone. So far the best only software alternative I could find is this experimental project. Edit 2 Found this forum discussion today. The participants state that there is no old-school modem in the BlackBerry. Edit 3 When I place a call in PuTTY with ATD, immediately after the call is answered (and the callee is initiating the handshake) the cellphone returns OK. This is not the expected behavior for establishing a data connection. The phone should reciprocate the handshake, and upon success return CONNECT. (Alternatively it should return BUSY or NO CARRIER, but never simply OK.) Windows DUN must be interpreting this as the "Error 678" I was seeing.

• How to setup the Mac OS X Terminal so it's *just peachy*?

  - by kch

  Hi all, My Terminal is awesome, has every detail just right (for me anyway), and now I'm setting up a few new macs around here and I have no idea whatsoever how to get their terminals to a pretty state. My user account is rather old, has been migrated over many OS X releases and machines, so my Terminal setup has grown rather organically over the years. What I need is a recipe to start from scratch, so 1) I know what I've done, and 2) I can reproduce it anywhere. Things I'm looking for: Full UTF8 support. Setting LC_*, displaying characters correctly, accepting input… I hear this got much easier in 10.5, maybe it all works out of the box now? Setup of OS X-style keyboard text navigation (option-arrows, etc) How you particularly handle meta-key support? (other than ESC'ing your way around) Other things to help our n00bs get around in the shell, such as: List of useful default key bindings (^A, ^D, etc…) Mac-specific .profile, .inputrc goodness Mac-specific tools such as pbpaste & pbcopy, Open Terminal Here, etc If at all possible, a list of files to copy over to another machine that encompasses all the changes made to tune the Terminal. (dotrc files, plists, etc) And, well, anything else really. Just keep the scope on the Mac OS X Terminal application, rather than general unix setup and tools. I think a collection of incomplete answers would be a good start. Post one or two things you remember having done, we'll vote them up, and after a few days I'll try to compile it all into a summary answer.

• Windows freezes when watching videos

  - by cornerback84

  I have Acer laptop Aspire 5740 - 5780 with windows 7 Ultimate 32 bit. I am using Chrome. Windows is 1 year old, but it's not the first time this has happened. Windows freezes whenever I am watching videos on facebook/youtube or when using SopCast. I thought there was some faulty plugin, so I recently re-installed chrome but it happened again. No keys work, and the sound of whatever I am listening starts repeating like grrrr..drrrr. Its seems like the sound in very slow motion. One time I left it in this freeze state for 5 min and it recovered automatically. It usually does not happen when I am using windows media player. I had some codecs installed but I removed them to see if that fixes. So far, I have narrowed it down to youtube/footytube videos and sopcast. I have checked event logs but nothing special. Is there any way I can narrow down the problem or any suggestions on how to fix it. I'd like to add that it does not always happen. Sometimes windows goes days/weeks without freezing, and sometimes it take a min into video to freeze.

• How is the extra mSATA SSD disk used/configured in a Dell XPS laptop?

  - by Mark

  Some machines in the new XPS laptop range from Dell come with a regular, large (500GB+) HDD and an additional 32GB m-SATA SSD. The only detail I can find about this extra drive on the Dell site is this: Store your important files, multimedia and photos with XPS 15’s large hard drive options. To get instant access to your media, choose an optional mSATA solid-state drive (SSD) that can boot up to twice as fast as a regular hard drive and resumes in less than 1 second. I'd like to know more about how this extra drive is set up and used, specifically: Is anything installed on it (e.g. OS files or a boot loader) or is it just used as swap space? Is the m-SATA drive visible as a lettered drive in Windows? (I'd guess not if it's used for swap file only.) Is this unusual configuration likely to cause any problems later down the line - e.g. when upgrading to Windows 8? As usual, Dell's sales team haven't been able to help. If anyone's actually got a Dell machine with this or a similar hard drive set-up and can give a definitive answer rather than speculation I'll accept the answer.

• Dell laptop keyboard doesn't work

  - by Tam

  I'm trying to fix my in-laws laptop, it's a Dell Studio 1745 that's running Windows 7 64 bit. The problem is that most of the keys on the keyboard do not work. The function keys work and the caps lock and numpad keys work, but no other keys do. If I hit the F2 key enough times when starting up, I can get to the BIOS, but after that even the function keys stop working. If I let it go all the way to the Windows login screen, I can see that the caps lock and num lock work - little images on screen actually appear, but they don't toggle the state of the key, i.e.,capslock is always off, numlock is always off. Using the fn+function combo works, so changing the brightness, etc. works fine. I'm stumped. I've tried disconnecting power and battery and leaving it for an hour or so before starting up but that hasn't helped either. Also - this might be a red herring - the touchpad is failing as well, the MS Device Manager says that it's failing with status 10, "unable to start device"

• Apache load balancer with https real servers and client certificates

  - by Jack Scheible

  Our network requirements state that ALL network traffic must be encrypted. The network configuration looks like this: ------------ /-- https --> | server 1 | / ------------ |------------| |---------------|/ ------------ | Client | --- https --> | Load Balancer | ---- https --> | server 2 | |------------| |---------------|\ ------------ \ ------------ \-- https --> | server 3 | ------------ And it has to pass client certificates. I've got a config that can do load balancing with in-the-clear real servers: <VirtualHost *:8666> DocumentRoot "/usr/local/apache/ssl_html" ServerName vmbigip1 ServerAdmin [email protected] DirectoryIndex index.html <Proxy *> Order deny,allow Allow from all </Proxy> SSLEngine on SSLProxyEngine On SSLCertificateFile /usr/local/apache/conf/server.crt SSLCertificateKeyFile /usr/local/apache/conf/server.key <Proxy balancer://mycluster> BalancerMember http://1.2.3.1:80 BalancerMember http://1.2.3.2:80 # technically we aren't blocking anyone, but could here Order Deny,Allow Deny from none Allow from all # Load Balancer Settings # A simple Round Robin load balancer.

I get SSL negotiation errors. Even when I do get that to work, I will need to pass client certificates. Any help would be appreciated.

• Computer slow after installing 32GB RAM

  - by John Gilmore

  I'm currently running very large network simulations for my PhD research, for which I need lots of RAM. I have a Core i7 2600K processor with a Gigabyte GA-Z68AP-D3 motherboard, running Windows 7 professional 64bit. I bought the system with 8GB (2x4GB) DDR3 1600 MHz Corsair Vengeance RAM and the system ran like a dream. I'm planning to upscale my simulations so I removed the 2x4GB RAM and installed 4x8GB DDR 1600 MHz Corsair Vengeance RAM. When I rebooted the system, boot time was much longer than usual (10 mins just to get to login screen). After logging in, the whole system was unresponsive. I tried playing some games (Bioshock 2), but it was unplayable. I've not had this problem before and I have an ATI Radeon HD 5850 graphics card, so that's not the problem. The only thing that's changed is the RAM. I've looked through the specifications of Windows, my motherboard and my CPU and they all state that 32GB of RAM is supported. Does anyone have an idea of what's going on? Any help would be greatly appreciated.

• Restrict Computer or Users from Internet but allow access to intranet and Windows Update / ePO?

  - by MoSiAc

  So this may be impossible but I've been asked to try and find something about it. So far nothing I have found is possible. I need to restrict specific machines or user accounts from regular Internet access but let them have access to the intranet portion of our network. I do not have Active Directory control, nor does anyone at my local workplace (corporate control in a different state). I have tried going through IPsec and doing this per local machine, but that system seems to have been removed from the images that are installed on these machines so that is out. So far the only other option I can think of is assigning the machines a specific ip address and removing their gateway access. This would probably work but the machines need to be able to receive updates that are being pushed to them through ePO and LanDesk. I would really like to do this on the user level because then if I need to do tech work to the machine and need internet access I can get to it but a "special" user could login and not be able to get into anything.

• Securing NTP: which method to use?

  - by Harry

  Can someone good at NTP configuration please share which method is the best/easiest to implement a secure, tamper-proof version of NTP? Here are some difficulties... I don't have the luxury of having my own stratum 0 time source, so must rely on external time servers. Should I read up on the AutoKey method or should I try to go the MD5 route? Based on what I know about symmetric cryptography, it seems that the MD5 method relies on a pre-agreed set of keys (symmetric cryptography) between the client and the server, and, so, is prone to man-in-the-middle attack. AutoKey, on the other hand, does not appear to work behind a NAT or a masquerading host. Is this still true, by the way? (This reference link is dated 2004, so I'm not sure what is the state of art today.) 4.1 Are public AutoKey-talking time servers available? I browsed through the NTP book by David Mills. The book looks excellent in a way (coming from the NTP creator after all), but the information therein is also overwhelming. I just need to first configure a secure version of NTP and then may be later worry about its architectural and engineering underpinnings. Can someone please wade me through these drowning NTP waters? Don't necessarily need a working config from you, just info on which NTP mode/config to try and may be also a public time server that supports that mode/config. Many thanks, /HS

• iCloud backup merges or overwrites?

  - by Joe McMahon

  The following happened today (it was six AM my time, so yeah, I was dumb and dropped stitches in this process): A friend had a problem with her iPhone and needed to reset it. Unfortunately she did the reset while connected to iTunes and the restore process kicked in. In my sleepy state, I told her to go ahead. She did, and restored the most recent local (iTunes) backup (from July last year - she doesn't back up often, as she has an Air which is pretty full). During setup on the phone, she was prompted to merge data with the iCloud copy, and did so. There was no "restore from iCloud" prompt. Obviously I should have made sure she was disconnected from iTunes before she did the reset, or had her set it up as a new device and then restored from iCloud, but water under the bridge now. (Side question: could I have had her disconnect and then restart the phone again and avoid this whole process?) The question is: was the "merge" that happened in this process a true merge, or a replace? Her passwords for Mail were wrong, since they were the old ones from the old backup. If she does the wipe data and restore from iCloud, will she get her old SMSes and calendar entries back? Or did the merge decide that the phone, despite it being "old" was right and therefore the SMSes, calendar entries, etc. were discarded? As a recovery option, I have a 4-day-old iTunes backup here from ~/Library/Application Support/MobileSync/Backup, but she and the phone are 3000 miles away, and it's 8GB, so I can't easily restore it for her. I do have the option of encrypting it and mailing it on a data stick if the iCloud backup is now toast. Should she try the wipe and restore from the cloud (after backing up locally), or should I just get the more-recent backup in the mail? My goal is to get everything (especially the SMSes) back to the most recent version possible.

• What's throttling the database?

  - by Troels Arvin

  Hardware: Intel x86_64 with 192GB of RAM. OS: CentOS 5.4 x86_64. DBMS: DB2 v. 9.7.1 64 bit. During certain special workloads (e.g. parallel REORGs/RUNSTATs), I've seen the server transporting 450MB/s with 25000IO/s (yes, there is probably some storage system caching happening here) while all CPU cores were happily working in an even mix of usermode/wait. And disk benchmark tools can also bring some very satisfying bandwith and IO/s numbers to the table. On the other hand, we also have another scenario: A single rather complex query with at least one large table scan. db2's "list applications" reports that the query is Executing (not locked). IO: At most 10MB/s, 500 IO/s; CPU: two cores in 99.9% wait state, all other cores 100% idle. The tables which the query reads from have been altered to have LOCKSIZE=TABLE, so I would think that lock list work is zero. What's going on in such a situation? What tools/snapshots/... can I use to gain better insight in such a case?

• nVidia performance with newer X and newer driver abysmal with Compiz

  - by Nakedible

  I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem. EDIT: In the end, nothing really worked, and I got really annoyed with the state of compiz and its support in Debian. Many nVidia driver revisions have passed and I am using Gnome 3 now, so I am accepting the best answers to this question even though the issue was not resolved.

• TFS 2010 Subfolder Permissions

  - by gmcalab

  I am a TFSAdmin and when I have a TFS project in which a subfolder needs specific permissions to deny some users. So, I right click on the folder in question hit Properties, and click the Security tab. There I select the Windows User or Group radio, then click Add. I put in the AD User that I want specific permissions for and hit Check Names. That resolves, so I click OK. Next, I select the permissions to Allow or Deny below in the Permissions for list. I hit OK. The permission are honored by TFS, this user no longer has PendChange permissions and I was expecting. The odd thing is, I was expecting to be able to go back into the Security tab and see that User in the list of Users and Groups and see the current state. But the list is always empty. Not sure why, but the permissions are definitely being honored, I can re-add the user with different permissions and those are also honored. Any ideas why the current users are not showing up in the Users and Groups list under the Security tab for a folder's properties? I also used the tf permission $\... to see if there were any permissions but it always returns There are no permissions set for this item (Inherit: Yes)

• Install multiport module on iptables

  - by tarteauxfraises

  I'am trying to install "fail2ban" on Cubidebian, a Debian port for Cubieboard (A raspberry like board). The following rule failed due to "-m multiport --dports ssh" options (It works, when i run manually the command without multiple options). $ iptables -I INPUT -p tcp -m multiport --dports ssh -j fail2ban-ssh" iptables: No chain/target/match by that name. When i make a cat on "/proc/net/ip_tables_matches", i see that multiport module is not loaded: $ cat /proc/net/ip_tables_matches u32 time string statistic state owner pkttype mac limit helper connmark mark ah icmp socket socket quota2 policy length iprange ttl hashlimit ecn udplite udp tcp The result of iptables -L -n -v command : $ iptables -L -n -v Chain INPUT (policy ACCEPT 6 packets, 456 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 3 packets, 396 bytes) pkts bytes target prot opt in out source destination Chain fail2ban-apache (0 references) pkts bytes target prot opt in out source destination 0 0 RETURN all -- * * 0.0.0.0/0 0.0.0.0/0 Chain fail2ban-ssh (0 references) pkts bytes target prot opt in out source destination 0 0 RETURN all -- * * 0.0.0.0/0 0.0.0.0/0 What can i do to compile or to enable the multiport module?

• Enable bitlocker an save key to share

  - by user273694

  I have searched all over the web but cannot find a complete answer to this: How to enable Bitlocker on a laptop with TPM, and store a file with the Bitlocker recovery key and TPM password by USING THE manage-bde command line tool. The file should be the same as when created in the Bitlocker manager UI. I DO NOT want to save to AD. The same question was asked here but was not answered correctly. The goal is to write a script to be used with an endpoint manager. I have tried the following: manage-bde -on C: Works fine, but does not create or save a key. manage-bde -on C: -rk C:\myfolder\ and manage-bde -on C: -RecoveryKey C:\myfolder\ -rp The output from the last two methods state that a key has been saved to c:\myfolder and so on, but that is not the case. It also says that I have to: Save the password in a secure location Insert a USB flash drive with an external key file into the computer. Restart and run hardware test type "manage-bde -status" to check if the hardware test succeeded After a restart, I get an error saying that Bitlocker could not be enabled because the bitlocker startup key or recovery kpassword cannot be found on the USB device.... C: was not encrypted. Why am I asked to insert a USB?? I simply want to encrypt the hard drive and save the recovery information to a file automatically. Is that too much to ask? Help please!
