• Extend Linux Desktop to another X Windows Display

  - by unknown (google)

  Hello, I am a long time Linux user of the Xinerama and other technologies for extending a desktop to multiple monitors. However when I travel with my laptop I miss the multi-monitor support I enjoy at home. Recently I acquired a second laptop for a low price. Both laptops are running Fedora (versions 10 and 11 respectively). I use Gnome as my primary desktop environment. I know about synergy. I use synergy all the time to control the screen of other Windows / Linux systems I use. I would like to know, can I sit both my primary and secondary laptops together and achieve a Xinerama-like extended desktop environment? Ideally I would like to start a GNOME session on my primary laptop. And then start a X-Windows Desktop on my secondary laptop and extend my primary laptop's desktop onto it. I would like to be able to move Windows from the primary desktop to the secondary laptop desktop. Would I need to use synergy to do this with some other bit of X-Windows technology? Or is there X-Windows technology that will do all this for me? I am familiar with X Windows ability to display applications remotely. I am also familiar with Nomachine's NoX.

• Outdoor WiFi Mesh Topology vs. Repeaters

  - by IronJaxor

  Here's the current configuration in our organization (which I believe is incorrect): We have a number of Cisco 1500 series AP's (22 in total), that are mounted outdoors to provide seamless WiFi coverage over a large area. Each AP however has its own physical ethernet connection back to the WLC (All the AP's are marked as Root AP's). They are all broadcasting the same SSID. We have tried to stagger the channel selection but because there are only three non-overlapping channels to choose from, and in some areas the density of AP's is quite high, there is multiple places of channel interference. With this configuration we experience 100-150 disconnects from clients every day. (Our clients are mobile so they move throughout the coverage area constantly). My idea is to switch the AP's to the same channel thereby forming a wireless mesh, use the built in functionality of the 1500 series to use 802.11a as the backhaul, designate one or two AP's as root AP's and wire them back to the WLC. Thereby forming a WiFi mesh, which if I'm not mistaken is the point of the 1500 series in the first place! I am however completely new at WiFi networks and wondering if I am simply mistaken in what I believe my proposed changes will enable, or if there is a better way to tackle the WiFi topology.

• Changing SkyDrive default location on Windows 8.1

  - by jmblack

  Update: This issue is due to the use of any non-local location for the SkyDrive folder. I've currently worked around this by using a local folder, but this has not resolved the original problem. I am trying to change the location where SkyDrive is located in Windows 8.1. This is the newly integrated SkyDrive, and not a downloadable client. There are a couple of similar questions on this site, but they pertain to Windows 8 and 8.1 Preview: Changing the SkyDrive default path in Windows 8.1 (Windows 8.1 Preview) How do I change the SkyDrive default folder in Windows (Windows 8) The SkyDrive folder is a system folder in 8.1, and like other system folders, has a Location tab in its properties that theoretically lets you change its location. I was able to do this with other system folders such as Downloads and Pictures, but there is an error when I try to change this for SkyDrive. Edit: The location that causes this error is a mapped network drive. The error does not occur when trying to move SkyDrive to another location on the same drive. There are no permission restrictions on the mapped network drive. Edit #2: This is the method I followed that produced the error: A screenshot of the error can be found here Has anyone else encountered this or have any information on this?

• In Windows 7 power management, is it possible to set different sleep settings for different SATA disks?

  - by Ben Voigt

  I'm having an issue with Windows 7 either freezing up or generating a BSOD coming out of sleep. I suspect that it is related to my boot/OS drive, an OCZ Vertex SE SSD, because numerous other Vertex users have reported sleep problems. Notably, if I put the computer to sleep, it almost always wakes correctly. If it goes to sleep after a timeout, it almost always BSODs. I disabled timed sleep and now it freezes when left unattended. My next step is to disable "Put hard disks to sleep after X minutes", but I'd like to change this setting only for the SSD and not for the rotating data disks, which I would like to spin down normally. Does anyone know a place to configure sleep on a per-disk basis? I don't need to set different timeouts on different disks (although that would be nice), simply setting "this disk sleeps" and "sleep is disabled for this disk" would be great. Additional system information: Windows 7 Ultimate x64, Core i5 - P55 chipset, Intel RST drivers are installed. One SSD, two rotating HDD, and a DVD-RW drive are all connected to the Intel SATA ports. I could potentially move some of these to my motherboard's other SATA controller if that would help.

• Network topology for both direct and routed traffic between two nodes

  - by IndigoFire

  Despite it's small size, this is the most difficult network design problem I've faced. There are three nodes in this network: PC running Windows XP with an internal WiFi adapter.Base station with both WiFi and a Wireless Modem (WiModem)Mobile device with both WiFi and WiModem The modem is a low-bandwidth but high-reliability connection. We'd like to use WiFi for high-bandwidth stuff like file transfers when the mobile is nearby, and the modem for control information. Here's the tricky part: we'd like the wifi traffic to go directly from the mobile to the PC, as rebroadcasting packets on the same WiFi channel takes up double the bandwidth. We can do that with a manual configuration by giving the both the PC and the base station two IP addresses for their WiFi interfaces: one on a subnet shared with the mobile, and one on their own subnet. The routes on the PC are set up so that any traffic going to the mobile via WiModem goes through the secondary IP address so that return traffic from the mobile also goes through the WiModem. Here's what that looks like: PC WiFi 1: 192.168.2.10/24 WiFi 2: 192.168.3.10/24 Default route: 192.168.2.1 Base Station WiFi 1: 192.168.2.1/24 WiFi 2: 192.168.3.1/24 WiModem: 192.168.4.1/24 Mobile WiFi: 192.168.3.20/24 WiModem: 192.168.4.20/24 We'd like to move to having the base station automatically configure the mobile and PC, as the manual setup is problematic when you start having multiple mobiles and PCs. This means that the PC can only have 1 IP address and needs to be treated as being pretty simple. Is it possible to have a setup driven by DHCP on the base station that is efficient with bandwidth?

• INSERT DELAYED on locked tables blocks PHP processes to continue

  - by sw0x2A

  Our webservers write some tracking information into a MySQL database (using INSERT DELAYED into MyISAM table). When a huge SELECT query is executed on this table or when it is locked for another reason, the webserver processes (with INSERT DELAYED) are waiting for the database and in some cases the MaxServer limit is reached in Apaches, so they will stop serving requests. We use INSERT DELAYED because The DELAYED option for the INSERT statement is a MySQL extension to standard SQL that is very useful if you have clients that cannot or need not wait for the INSERT to complete. This is a common situation when you use MySQL for logging and you also periodically run SELECT and UPDATE statements that take a long time to complete. Quote from MySQL documentation. I am wondering why the Apache processes are waiting for the INSERT DELAYED to finish. And what can I do to just send the data and forget about it. (Since this is logging data, I do not care if we lose some entries.) Even when the table is locked the PHP script should just go on and should not wait for an answer of MySQL. (We do not want to setup Master-slave for this table but we are thinking about move this data to some NoSQL database. But for now I would like to know why INSERT DELAYED is not working as expected.)

• How can I create a separate toolbar from the Task Bar?

  - by Iszi

  In Windows XP, you could separate toolbars from the Task Bar by dragging them to the desktop. They could then be left lying about anywhere on your screen or, my preferred option, docked to any side of the screen. I found this particularly useful to keep a handy list of common phone numbers quickly accessible. I'd create a new toolbar pointing to a custom folder, and put a bunch of dead shortcuts in the folder that had names and numbers as their file names. I'd then dock the toolbar to the left side, set it to auto-hide and always on top (options which could be set separate from the Task Bar as well) and it would be readily available no matter what else I was doing on my system. However, on my Windows 7 system, I seem unable to perform the crucial step of pulling the new toolbar off of the Task Bar. This is of course with the Task Bar "unlocked" so that I can move all my toolbars around. Is there something I'm missing here, or is this a feature that's been disabled in Windows 7? Is there any way to re-enable it, or otherwise achieve similar functionality? I'd rather be able to do this without additional software, if possible.

• Setting up Web server so it is easy to migrate

  - by Nyxynyx

  Hi I am about to move my site from a VPS to another host's dedicated server. One of my concern is about scaling the site in the future that involves a change of server. Now that I am starting the dedicated server from scratch with only the OS, this means that I need to install the web server stack, including Apache and its mods, PHP, MySQL, PostgreSQL, Tomcat, Solr and a few other softwares like ImageMagick and git. Question: Is there a way for me to setup this new dedicated server such that I can easily migrate the entire site, both the technology stack and the code to the a newer server (upgrade from this new dedicated server) easily without reinstalling and reconfiguring everything? The code for the website is being handled by git and github so thats not a problem. I'm more conerned about the rest of the software required. Side question: The current VPS uses CentOs with cpanel and it seems that many packages are outdated on yum and cpanel interfers with the installation of many packages. Which OS should I go with for the new server? Ubuntu?

• How to define nodes from a Hiera file in Puppet?

  - by Pigueiras

  I am using puppet and the puppet network device management module and I am trying to build my custom type. In the built-in type for the routers configuration, you can specify a list of nodes and then the configuration inside that node: node "c2950.domain.com" { Interface { duplex => auto, speed => auto } interface { "FastEthernet 0/1": description => "--> to end-user workstation", mode => access, native_vlan => 1000 # [...] More configuration } What I am trying to do, is to move the manifest declaration of the nodes and the configuration of my custom type to a Hiera file like this one: nodes: - node1 - node2 config_device: node1: custom_parameter: "whatever1" node2: custom_parameter: "whatever2" And then in the manifest iterate over the hiera file creating the nodes with the configuration of each node with something like (I am taking as reference this question in serverfault): class my_class { $nodes = hiera_array('nodes') define hash_extract() { $conf_hash = hiera_hash("config_device") $custom_paramter = $conf_hash[$name] ## TRICK lies in $name variable node $name { my_custom_device { $name: custom_parameter => $device_conf['custom_parameter'] } } } hash_extract{$pdu_names: } } } But for this solution I have two problems, I can not define a node inside a define and I can not parameterize a node name. So, is there any way to declare nodes from a Hiera file with their configuration inside?

• 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:---------".

• System randomly freezes yet mouse still moves, SSD out of reallocatable sectors, should I replace it?

  - by user784446

  This problem has lasted for the past 48 hours. The first time it happened, a program I was running stopped responding, so I tried to end it from task manager. The processes at first were listed fine until hovered upon. Eventually, despite the mouse still being able to move, after a few persisting clicks the mouse finally stopped moving. The screen went blank shortly thereafter. The second time it occurred, items on the screen stopped responding - hovering over the taskbar or such wouldn't elicit a response. Sound would still play however. Eventually, the mouse became unresponsive and the system restarted itself. I suspect that it may be a problem of my SSD drive. After looking through some Google search results, I downloaded HDTunePro to determine if there's a problem with the drive. Results returned a problem of reallocated sector count. An error scan also revealed 48 bad sectors. Also, an attempt to backup the contents of the most important areas of the drive returned a few explorer "Error: cannot read source from disk" errors. Should I ditch the drive and use another drive or is there anything that can be done to repair the drive? SSD: OCZ Petrol 64gb CPU: AMD Athlon II X4 640 RAM: Generic 3GB DDR2 Motherboard: Gigabyte MA74GM-S2H OS: Windows 7 Ultimate x64 Thanks!

• Xen or KVM? Please help me decide and implement the one which is better

  - by JohnAdams

  I have been doing research for implementing virtualization for a server running 3 guests - two linux based and one windows. After trying my hands on Xenserver, I am impressed with the architecture and wanted to use the opensource XEN, which is when I am hearing a lot more about KVM, about how good it is and it's the future etc. So, could anyone here please help me answer some of my queries, between KVM and XEN. Based on my requirement of three VMs on one server, which is better for performance - KVM or XEN, considering one the linux vm's will works a file-server, one as a mailserver and the third one a Windows server? Is KVM stable? What about upgrades.. What about XEN, I cannot find support for it Ubuntu? Are there any published benchmarks on both Xen and KVM? I cannot seem to find any. If I go with Xen, will it possible to move to KVM later or vice versa? In summary, I am looking for real answers on which one I should use.. Xen or KVM?

• Full Apache config migration

  - by Victor Rashkov

  I searched alot and didn't find an applicable answer. I have a working LAMP setup on Ubuntu machine and I have to migrate to a new server in a different country. The old server is 11.10, the new server is 12.04LTS. My problem is that I simply can not remember the steps I followed when I configured the current server which is not the basic LAMP install. It is Apache with FastCGI, SuEXEC, a GD library, worker MPM and all sitting on top of a mhddfs system. There are also other configs I've changed and I can not recall what they are. Because of the complexity of the setup, my attempts to migrate to the new server fail. I get permissions errors, cgi problems etc. Therefore my question is : Is there a sane way to simply tar a full backup of the current web server installation, including MySQL, Php amd the apache server with all configs, and then move it to the new machine? I shall be forever thankful on any advise. So far non of thise I found here gave me an answer. Thanks!

• Changing the modified date of a message in Exchange 2010

  - by jgoldschrafe

  My organization is in the middle of a process to move their Exchange 2010 messaging system from one archiving platform to another. As part of this process, we need to restore all archived messages back into users' email accounts, and then let the new system import them again. The problem is that when the messages are dumped back, the modified date on the message is set to the date it was restored, which trips up message archiving and basically means nobody will have anything archived for six months. So you don't have to ask: no, our archiving platform only uses the modified timestamp on the message and cannot be altered to temporarily use the sent or received timestamp instead to determine whether to archive it. We and others have asked for the feature, but it doesn't exist right now. What we're looking for is a method to go through the user's mailbox and alter the modified timestamp of each message (or preferably received more than X months ago) to the received date of the message. We also don't want to spend more on this tool per user than we're spending on the archiving solution in the first place. We've run across a few tools that are something ridiculous like $25 per user. I don't think we're even paying close to that for Exchange and the archiving solution put together. Whatever we settle on should function on a live mailbox with no downtime. Playing around with PST imports and hacky little things like that isn't going to work. We're fine with programming/scripting, if anyone knows the best way through PowerShell, COM automation or some other way to best handle this.

• Shortcut To Full Screen App In Lion

  - by omghai2u

  I postponed getting OSX Lion for as long as I possibly could. Now that I have it, I'm having lots of difficulties getting it to perform how I want. On Snow Leopard my typical setup for working was 4 spaces. I'd keep a Windows VM open on Space #4 full-screened, a Linux open on space #3, and I'd do other stuff on spaces #1 and #2. My keyboard shortcut allowed me to switch between my Windows work (Command + 4) to my Linux work (Command + 3) very quickly, and without the need for my hands to leave the keyboard (or effectively to even quit typing). Productivity was good. I see that on Lion a full-screened VM (and yes, they need to be full screened, Fusion's Unity won't cut it for what I need to do) is its own separate Desktop. I have set up 4 desktops and made my keyboard shortcuts to move between them Command + # just as before. But how do I get my full-screened VM to be one of those already existing desktops? Or, rather, how do I make a short-cut for the full-screened app?

• Display errors using VMWare Player and Remote Desktop on Windows XP

  - by Tim

  I've come up against a weird display issue that I can't seem to find any "fix" for. When I first boot up my computer, everything behaves normally. If I start to use VMWare Player and/or Remote Desktop, my desktop starts having some odd video issues. The frames for some windows aren't drawn at all, if I move windows around rapidly, the area under where the window used to be isn't cleared (still shows artifacts of the content of the window), etc. In some cases, the minimize / restore / maximize buttons aren't drawn (but are click-able if you can guess where they are). I've tried the usual stuff - current drivers all around, using a single monitor, etc.. none of it seems to have any bearing. If I try to disable hardware acceleration, it tends to crash the computer. As I said earlier, it's running Windows XP, dual monitors, an NVidia en8400GS video card, asus p7p55d motherboard. Not sure what other pertinent details are needed. I would appreciate any help or suggestions!

• Solaris 10: How to remove devices from a zpool with /usr currently mounted?

  - by cali-spc

  I use Solaris 10 on SPARC. I have /usr legacy mounted on a zpool 'usr-pool'. I now need to move some of the devices in usr-pool to another zpool which is running out of room. What is the safest way for me to do this? I already know that (since my zpool is not mirrored) I need to destroy and recreate the zpool. I know how to backup and restore a zfs snapshot. However... I'm stumped on how to unmount usr-pool without losing access to the commands I need on /usr to complete the backup/restore. Cursory research indicated that I should boot to OpenBoot (init 0) and then 'boot cdrom -s'. I did this but none of the zpools are accessible on that runlevel. I also read I could just copy /usr to another location, symlink /usr to that location, then do my backup/restore. Is that safe to do? I would appreciate some guidance. S.

• Cloning a failing disk (Win 7)

  - by daveh551

  I have a Windows 7 machine with several partitions on a 1.5T drive. Windows has been complaining about disk errors and imminent failure, so I have purchased a new 2TB drive. The failing disk has not completely failed, and, in fact, I was able to boot Windows from it (after a couple tries) and examine the SMART logs - the only RED item was 1 sector being reallocated. But when I try to Clone it to the new Drive using Acronis True Image Home (2010), True Image can see the drive, the partitions, and the contents, but when it goes to actually do the clone, it says "Failed to move. Make sure the destination disk is not smaller than the source disk, and that there are not errors on the disk" (or something like that). What are some other options for simply cloning the failing drive. I'd like to clone the entire disk, but am willing to do it partition by partition if necessary. Was this a known failing of the 2010 edition of ATI, or is it really something hosed in my system. Would upgrading to the 2012 edition be likely to work any better? (I'd download the trial and try it out, but if I remember right, the cloning operation is disabled in the trial version), and I don't have enough free disk space to make an entire image.) What are some other cloning software packages if ATI won't work? Note that I'm only looking to clone the disk, not make an image as a back up - I use Ghost for that, and can fall back to that if I have to. It looks to me like CloneZilla would do the job. Any recommendations? Thanks, and if this duplicates other questions, I apologize.

• LighTPD and PHP not working if outside of LightTPD folder

  - by Marco83

  I need to set up a simple web server with PHP on Windows XP that a number of different people will use for local testing. I'm using LightTPD 1.4.30-4-IPv6-Win32-SSL and PHP 5.2. So far I've created this folder structure: tools/ LightTPD/ htdocs/ PHP/ I set up PHP as CGI and the document root as server_root + "/htdocs". It works fine (well, it's slow but I don't want to bother with FastCGI for now :) ). My problem is when I try to put the htdocs outside of LightTPD folder, like this: htdocs/ tools/ LightTPD/ PHP/ I update the document root to server_root + "/../../htdocs" and while static HTML pages work fine, PHP pages stop working (they return a "No input file specified"). I literally just change the document root, I didn't change anything in the php.ini or anywhere else. Please also note that I left all doc_root, user_dir and cgi.force_redirect to the default values in php.ini, and it works when htdocs is inside LightTPD, but not when I move it ouside. Any idea of why it's breaking?? Here's my lightTPD.conf: server.modules = ( "mod_access", "mod_accesslog", "mod_alias", "mod_cgi", "mod_status", ) include "variables.conf" include "mimetype.conf" # THIS WORKS server.document-root = server_root + "/htdocs" # THIS DOESN'T #server.document-root = server_root + "/../../htdocs" server.upload-dirs = ( temp_dir ) index-file.names = ( "index.php", "index.pl", "index.cgi", "index.cml", "index.html", "index.htm", "default.htm" ) server.event-handler = "libev" url.access-deny = ( "~", ".inc" ) $HTTP["url"] =~ "\.pdf$" { server.range-requests = "disable" } static-file.exclude-extensions = ( ".php", ".pl", ".cgi" ) server.errorlog = server_root + "/logs/error.log" ######### Options that are good to be but not neccesary to be changed ####### dir-listing.activate = "enable" #### CGI module cgi.assign = ( ".php" => server_root + "/../PHP/php-cgi.exe" ) status.status-url = "/server-status" status.config-url = "/server-config"

• Puppet: is it ok to "force" certname when you expect to shuffle nodes around?

  - by Luke404

  We all know (good example on SF) that Puppet hostname detection could be... fun. At our company (and I guess we're not alone at this) we usually pre-configure servers at our offices and test them before bringing the gear to a remote datacenter and rack them. Of course the reverse dns will change when doing that, even if we don't change the actual hostname of the system. We're slowly drafting our puppet setup and I'd like to be sure those moves won't create problems. My idea is to explicitly configure the desired full FQDN of the system as certname in puppet.conf at server provision time (before the very first puppet run). My process would look something like this: basic o.s. installation basic network configuration, enough to reach the internet and resolve dns install puppet and set up certname start puppet and let him manage the whole configuration test, fix problems in config (via puppet), re-test, and so on... manually stop puppet set up new network configuration for the datacenter network move the machine to DC turn it on puppet should automatically start and keep on doing its job The process is supported by detecting the environment in puppet's manifests (eg. based on subnet, like they do at Wikimedia) and modify configuration as needed (eg. resolv.conf contents appropriate for each network). Each node's certname will never change for the whole system life cycle. Is there any problem with this approach? Could it be improved?

• How to resume XMPP groupchat window in Irssi (using bitlbee)?

  - by mcnesium

  I use Bitlbee to chat in XMPP-networks within my IRC-client Irssi. This works great so far, and recently I started using XMPP Multi User Chats as an alternative to IRC-channels. I set up a channel using chat add <account> <[email protected]> in the &bitlbee control window, set chan <room> set autojoin true and entered /join #room in the &bitlbee window to join that groupchat. It then appears as a unique Irssi window in the status bar. This seems to work ok too, but with one exception: Since I idle in the channels 24/7 my irssi has to cope with the every-night-24h-DSL-disconnection by the ISP. After it automatically reconnects, it does kind of rejoin that XMPP-groupchat, but the traffic of the groupchat does not go back to the unique irssi window, but keeps flooding &bitlbee with messages from root telling me about a Groupchat Message from unknown JID <jid>: <message> - which is the traffic of the groupchat. The unique groupchat window is gone after the reconnect, and I will again have to go /join #room in &bitlbee to get it back. Even worse, the window number is unused before I rejoin the groupchat, and if I get a query from any network, the window nests in that unused window spot, so I will first have to remove that query from the spot, and then move the rejoined groupchat to that window number. I want my groupchat window to resume after the reconnect just like every other IRC channel too. How can I get this done? Any ideas?

• How can I get write permission for the Web (Inetpub) directory on a new Win 7 machine?

  - by marcipollo

  I mirror my Web site on my laptop, and am trying to move the mirror site to a new laptop. I copied the files to the Inetpub directory, and can view them perfectly, but they are read-only (the check-mark is grey, not black), and I cannot change the permission. When I un-check the read-only attribute on the Inetpub directory, and click "apply" it displays a dialog box stating that I need administrative permission to change the attributes. (I am logged in as an administrator). When I click "continue," it pops up another dialog box saying access is denied to the attributes of the file: c:\inetpub\custerr\en-us\500-100.asp That dialog box has an "ignore" button, and if I click that, it appears to work through the directory tree setting the permissions. It leaves all of the files (leafs) set to "read-write," but the directories remain "read only." I am using 64-bit Windows 7. I stopped the IIS service while doing all of this. Might it have something to do with the fact that I copied the files from a different machine in the workgroup (my old laptop)?

• Plug-in device to front USB computer *sometimes* restarts

  - by Mark A. Nicolosi

  I've got a strange problem that very occasionally (maybe once a month) when I plug-in something to the front USB on my computer, the computer suddently restarts. This also happens when I touch the front USB ports sometimes. This has been going on for a few years and a lot of the components in my PC have changed. I thought it was my home wiring, but I moved last year and it still happened. I thought maybe it was the motherboard, but that was upgraded 9 months ago and it still happens. I thought it was my case, but I changed that recently and it still happens. I thought maybe it was my PSU, but I upgraded that yesterday and it still happens. I'm pretty sure this is an electro-static thing, but I thought that modern computers have protection against this sort of thing. Maybe I should move my case off the floor (carpet) and stop wearing songs all the time. Edit: Just to clarify this is a computer that I built. The components have been upgraded throughout the years and it's not much the same computer anymore. This doesn't happen very often, but it is annoying, because I don't know what the cause is. Anyone have any ideas?

• Exchange 2010 SP2 database size

  - by Chad

  I have a single Exchange 2010 sp2 environment with 3 DB stores. I am trying to reduce the sizes by moving the mailboxes to a spare DB and then deleting the empty database. I cleaned up the users mailboxes to reduce the sizes and set the retention periods to 1 day each and waited several days before moving mailboxes. The databases are backing up fine and clearing logs files but when I move the mailboxes I noticed they were taking a long time, even though some were less than 100MB. When I checked the new database size it seems like the orginal mailbox size might be moving (1GB instead of 100MB). Exchange is showing the expected smaller mailbox sizes when I run get-mailbox statistics against the DB. So if I have 5 mailboxes 100MB each it is showing like 3GB instead of around 500MB, and no whitespace. I keep waiting thinking mailby the retention period is not expired yet but it is much longer than 1 day already. I am setting them both to 0 today to see if that works. What am I missing to get the combined mailbox sizes to match the DB size minus whitespace?

• How to disable monitor auto detection in Windows 7?

  - by Jay Yother

  I am currently running Windows 7 Ultimate 64-bit with a dual monitor setup with an NVIDIA 7950 GT graphics card. One monitor is dedicated to this machine and the other monitor is connected to a DVI KVM switch. When I switch to my other computer, Windows 7 disables the monitor. However, when I switch back it does not re-enable the monitor. The only circumstance that automatically re-enables the second monitor is when I switch back after Windows has put the monitors into power save mode. I am continually having to bring up the NVIDIA control panel to have it re-enable the monitor. Under Windows XP I would just disable the NVIDIA service to prevent it from auto-detecting the monitor (which doesn't solve the problem under Win7), and in Vista there was a registry hack that would prevent this. It looks as though that has been removed in Windows 7. I have found similar questions posted on this site, but nothing that matches my problem exactly. The following link is the question that comes the closest, but does not provide a solution to the problem. http://superuser.com/questions/96683/how-to-fix-monitor-detection-on-windows-7 Is there a way in Windows 7 to disable monitor auto-detection? Update: I just added a second graphics card to my Windows 7 64-bit machine. I plugged one monitor into each graphics card. Now, when I use the KVM switch to switch back and forth it will re-enable the second monitor like it should. There are however, a few quirks with this. If I have a program maximized on the second monitor and it has focus, when I switch it will move to monitor 1. If I have a program maximized on the second monitor and it does not have focus, when I switch it will behave like it is minimized and when I bring it back up it will show up maximized on monitor 1. Definitely better than it was, but still looking for a way to disable the auto-detection.
