• Should I buy more RAM for my computer or a better CPU?

  - by Reijer The Coder

  I have recently bought a new laptop, an ASUS N56VJ-S4149H. I bought it to use it in all possible ways I could want, so that would be gaming downloading and streaming movies browsing the web and programming software. So far it has been running great but one thing annoys me a little bit. I frequently play Mount&Blade: Warband, it's a great game and you should check it out. Everything runs smoothly but only when I turn down the 'Texture Detail'. Otherwise it will lag a lot and I can't really play. Now my question is: Is this a problem of not enough RAM? At first I was really sure it was but after thinking about for a while I'm not anymore. My computer only has 4 Gigabytes of RAM and there is still a slot open. So will it improve when I buy another 8 Gigabytes? EDIT: It has an Nvidia GeForce GT 635M inside. and an Intel Core i5 3230M CPU with 2,6 GHz. Help and answers are really appreciated. Thanks to all.

• IIS Web Farm Framework servers are automatically set to "unavailable" even when they are healthy... And they never return to the available state!

  - by JohannesH

  I have 2 web farm configurations, one with 2 member servers and one with 3 member servers. I have health monitoring set up on both farms and the monitoring tool reports all servers as being healthy. However after a while all the servers are marked as being "Unavailable" and "Healthy" in the "Monitoring and Management" screen (in the "Servers" screen they are all listed with "Yes" in the "Ready for Load Balancing" column). Viewing the event log on both the web farm controller or any of farm servers doesn't reveal anything interesting. there are no warnings or errors in the period where the servers became unavailable. There are a couple of informational events about the worker process getting shut down due to inactivity but I don't hope this is the cause since that would mean that the farms will die during the night when the load is low. Am I missing something? EDIT: Btw, I think its very odd that the application pool shuts down on the servers since the health monitoring system is polling an aspx page on each server. Shouldn't that keep them going? EDIT2: Now I've also experienced this problem with the RTW version of Web Farm Framework 2.

• Multi-partition USB stick

  - by nightcracker

  In my freelance job as "the dude that fixes your computer" I have an extremely handy tool, a bootable USB stick with Ubuntu LiveCD that allows me to recover and investigate in a known, working environment. Now, I want to reformat this USB stick and reinstall with Casper-RW persistance. I did this a few times before with a FAT-formatted USB stick. It was a horror. The USB drive corrupted constantly, by people accidently removing the USB stick, the computer not properly shutting down, ETC. Now what I want to create a multi-partition USB stick so I can put Ubuntu on a ext partition, but still be able to store some Windows stuff in it, by having a secondary FAT partition. However I read somewhere that Windows will only check the first partition on USB sticks, giving a problem with the first bootable linux partition. Is this possible on some way? EDIT Perhaps it wasn't clear what the problem is. The problem is that I read somewhere that Windows will only recognize the first partition on a USB stick. But I want two partitions, a ext partition and a FAT partition. No issues so far, but in order to be bootable the ext partition must be the first one!

• Application Screen Repainting Issues

  - by Jeff Sheldon

  I have this issue lately at work. It drives be nuts, and I finally stopped to ask this question. It's quite often that an application I've been running just randomly fails to repaint itself for a while, usually in the editor screen. I most often see this occurring with Expression Web, Visual Studio 2008/2010 and SQL Server Management studio. These applications are what I work in the most, so I'm not surprised to mostly see it here. But I was curious if anyone else had a solution for this. I've tried: Reboots. The screen shot below is about 10 minutes after a reboot. New Video Drivers. This machine is running a Nvidia Quadro NVS 290 video card with the latest drivers. Closing other applications, this is the only thing running right now. As far as hardware, this machine has Dual Quad-Core Xeon 2.83ghz Processors, with 10 gigs of memory, running Windows XP SP3 64bit. Any help would be great. JNK EDIT: Per comments from deleted (wrong) answer: I'm running dual monitors. Set it to single display, still occurred. Rebooted, and tried it again, and it still occurred. Switched it back to dual screen. My resolution is only 1400x900 on each.

• Concurrent users with Quickbooks?

  - by airietis

  I work in a company with 3 people who regularly use the same Quickbooks file. However, they work remotely on different networks. I need to implement a solution that allows all three of us to access Quickbooks at the same time remotely (and each make changes at the same time). We have a spare desktop PC that can be utilized as a server. So, my question is: what is the cheapest and most hassle-free solution to solving this problem? I've considered using application cloud hosting, however, it is very expensive ($40 per user a month) and we are on a tight budget. Is it possible to install Quickbooks on my own server, and have them connect to it remotely? If so, what is the best way to accomplish this? Remote desktop protocol? Or is there a built in feature for this with Quickbooks Premier 2013? EDIT: As MDMarra mentioned, I am looking for a solution that offers true simultaneous access. Will using a dedicated server and having users connect to a VPN be a viable solution?

• RewriteRule causes POST data to get dumped before I can access it

  - by MatthewMcGovern

  I'm currently setting up my own 'webserver' (a Ubuntu Server on some old hardware) so I can have a mess around with PHP and get some experience managing a server. I'm using my own little MVC framework and I've hit a snag... In order for all requests to make it through the dispatcher, I am using: <Directory /var/www/> RewriteEngine On RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|bmp|gif|css|js)$ [NC] RewriteRule . HomeProjects/index.php [L] </Directory> Which works great. I read on Stackoverflow to change the [L] to [P] to preserve post data. However, this causes every page to return: Not Found The requested URL <url> was not found on this server. So after some more searching, I found, "Note that you need to enable the proxy module, and the proxy_http_module in the config files for this to work." The problem is, I have no idea how to do this and everything I google has people using examples with virtual hosts and I don't know how to 'translate' that into something useful for my setup. I'm accessing my webserver via my public IP and forwarding traffic on port 80 to the web server (like I'm pretending I have a domain/server). How can I get this enabled/get post data working again? Edit: When I use the following, the server never responds and the page loads indefinately? LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so <Directory /var/www/> RewriteEngine On RewriteCond %{HTTP_REFERER} !^http://(.+\.)?82\.6\.150\.51/ [NC] RewriteRule .*\.(jpe?g|gif|bmp|png|jpg)$ /no-hotlink.png [L] RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|bmp|gif|css|js)$ [NC] RewriteRule .

• Our clients site is redirecting to a pill scammy site [closed]

  - by Alex Demchak

  Possible Duplicate: My server's been hacked EMERGENCY We've usually host our clients site, but we aren't hosting this one. The website itself (weddle-funeral.com) works just fine. if you load google and search for weddle funeral stayton oregon - and click that link, the site links to a scammy pill site. I went through the site and there were some php files in the wordpress plugins that got quarantined by my antivirus. I removed ALL non essential files, and uploaded fresh versions of all the plugins, but it's STILL redirecting from google. I tried logging in to the cpanel (on a virtual private server), and the cpanel flashed a red warning screen The site's security certificate is not trusted! You attempted to reach XXXXX.com, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You should not proceed, especially if you have never seen this warning before for this site. (Keep in mind, that's for the HOSTING accounts CPanel) Is there something in the SERVER probably that's causing the redirect? EDIT: .htaccess file contents # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress

• Many clients on a wireless AP for UDP broadcast packets

  - by distorteddisco

  I asked this question on StackOverflow and was directed over here, so I'd appreciate any advice. I'm deploying a smartphone application as part of a live music performance that depends on receiving UDP broadcast packets from a wireless access point. I'm guessing that between 20 and 50 clients will be connected at any one time. I'm aware that a maximum of 20 clients per access point is advised, but as the UDP broadcast packets are ground through the LAN, how would I be able to link multiple APs together? I'm looking for recommendations on a suitable AP for this. The actual data transmission rates are very low - only a few kB/s - as I'm just sending small messages to the smartphone apps, and there will be no WAN internet connection. I tried it with a few connected peers on an adhoc wireless connection without any problems, but ran into dropped packet issues on an old WRT54G running ddwrt, though it's in pretty rough shape. What's the best way to do this? I suppose I could limit concurrent wireless connections to 20 clients... but more would be nice. EDIT: I should also say that it's purely one-way communication; the smartphone application is only receiving broadcast packets, not sending anything.

• Are there any benchmarks showing difference between hardware virtualisation enabled/disabled?

  - by Wil

  I have a 13" sub-laptop/large-netbook, it has an AMD Athlon Neo X2 L335, and I chose this one because it supports hardware virtualisation. In the end, I hardly do any virtualisation on it, however, when I do... it is fast. To my shock, I went in to the BIOS and saw that virtualisation was disabled! I turned this on and, I see no speed difference.... or at least none that I can tell. I do not have time to do a full set of benchmarks - and I run quite a bit of software on the host, so it wouldn't be scientific. I have searched quite a few places and I just can not find any benchmarks showing the difference of virtualisation bit enabled/disabled on the same hardware. Does anyone have any benchmarks they have seen that they can share? In addition, I know there was an uproar a while ago as Sony disable the hardware virtualisation on some models and only offer it in their higher models as a premium feature, however, apart from forcing an up-sell, are there any benefits to having it disabled e.g. battery/heat? I just can't find any information and can't work out why it would be disabled by default. Edit--- To add, The only thing I can find is that without it, you can not perform x64 virtualisation as fast. This is the only down side I can find. However, if this is the only difference, then I am still interested in the second part of the question - why offer the option to disable it?

• Server redirect

  - by Tyy

  I have asp.net app XYZ which requires SSL. I am supposed to work with IIS that has only one Web Site - DefaultWebSite - containing multiple apps and virtual directories (3rd party). So, my app is located at domain.com/XYZ. I have to meet these conditions: 1.) requesting DefaultWebSite (domain.com) will run my app. It could redirect to ../XYZ, but I would rather not to. If it has to be done this way, requesting DefaultWebSite or my app over both HTTP and HTTPS will always ends up with redirecting to https://domain.com/XYZ 2.) I can't touch any other apps or virtual directories, can't create additional Web Site, can't set DefaultWebSite to require SSL, ... EDIT: 3.) transmitted data (GET or POST) must be preserved I tried to: set Web Site root directory to my app, but it this caused other apps to crash because of my Web.config (not sure why). set up HTTP redirect on DefaultWebSite to https://domain.com/XYZ. This seems to work correctly, but this doesn't work if user requests my app directly (redirected to domain.com/XYZ/XYZ, or redirect loop). set up Default Document, but this seems to work only if it is located in the Web Site root directory. I know I could write simple .aspx with Response.Redirect, but... is there any better solution? Am I missing something?

• Linux as a gateway (no NAT)

  - by Hugo

  I'm trying to configure a linux server as a gateway/router, but I can't get it to work, and all information I've managed to find is NAT-related. I have a public IP block for the gateway and devices behind it, so I want the gateway to simply route packets to the internet - again: no NATing! I've managed to get the gateway to access the internet successfully (that was just a matter of configuring the IP and GW), and the computers behind it can communicate with it. [EDIT: more info] This is actually an IPv6 block (2800:40:403::0/48) (but I've found that most utilities and instructions can be easily adapted from IPv4 to IPv6 with little hastle). The server has too ports: wan: 2800:40:403::1/48 lan: 2800:40:403::3/48 One of the computers behind it is connected to it via a switch; 2800:40:403::7/48 The wan interface on the server can ping6 www.google.com without issues. The lan interface on the server and the client can mutually ping each other without issues (as well as SSH, etc). I've tried setting the server as a default gateway for the client, with no luck: client # route -A inet6 add default gw 2800:40:403::3 dev eth1 server # cat /proc/sys/net/ipv6/conf/all/forwarding 1 I don't want any filtering/firewalling/etc, just plain routing. Thanks.

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• What's the safest way to kick off a root-level process via cgi on an Apache server?

  - by MartyMacGyver

  The problem: I have a script that runs periodically via a cron job as root, but I want to give people a way to kick it off asynchronously too, via a webpage. (The script will be written to ensure it doesn't run overlapping instances or such.) I don't need the users to log in or have an account, they simply click a button and if the script is ready to be run it'll run. The users may select arguments for the script (heavily filtered as inputs) but for simplicity we'll say they just have the button to choose to press. As a simple test, I've created a Python script in cgi-bin. chown-ing it to root:root and then applying "chmod ug+" to it didn't have the desired results: it still thinks it has the effective group of the web server account... from what I can tell this isn't allowed. I read that wrapping it with a compiled cgi program would do the job, so I created a C wrapper that calls my script (its permissions restored to normal) and gave the executable the root permissions and setuid bit. That worked... the script ran as if root ran it. My main question is, is this normal (the need for the binary wrapper to get the job done) and is this the secure way to do this? It's not world-facing but still, I'd like to learn best practices. More broadly, I often wonder why a compiled binary is more "trusted" than a script in practice? I'd think you'd trust a file that was human-readable over a cryptic binaryy. If an attacker can edit a file then you're already in trouble, more so if it's one you can't easily examine. In short, I'd expect it to be the other way 'round on that basis. Your thoughts?

• PassEnv does not find ENV variables

  - by quodlibetor

  I've got this /etc/profile.d/myfile.sh: export MYVAR=myval I also have a PassEnv MYVAR line in a <virtualhost> section of an apache conf dir. That lets me do things like: $ echo $MYVAR myval $ python >>> import os; os.getenv('MYVAR') 'myval' $ sudo echo $MYVAR myval $ sudo -i root# echo $MYVAR myval But then, despite that being the case I get: root# /sbin/service httpd restart /sbin/service httpd restart Stopping httpd: [ OK ] Starting httpd: [Mon Oct 22 14:44:02 2012] [warn] PassEnv variable MYVAR was undefined [ OK ] And all of my attempts to access MYVAR from within my wsgi scripts just don't work. Thoughts? Am I doing something obviously wrong? EDIT for more detail I've got a swarm of computers/VMs and a swarm of developers working on a swarm of projects. I need a simple central place to keep environment information, the most common is the "environment" (dev/stage/prod). The scheme that we've got (modifying *.wsgi programmatically) is turning out to be more fragile than we'd like. The main options that I see are: put things in the shell environment put things in other config files Getting things into the shell environment is the best, because we won't need to write yet more duplicated "what is my environment" code.

• Working with different PHP version at the same time, php_value extension_dir not working?

  - by Gremo

  I need both PHP 5.4.7 and 5.3.17 running on Windows 7 x64 with Apache 2.2.23. This is my virtual host configuration: <VirtualHost *:80> DocumentRoot "C:/WAMP/Apache/htdocs/php54" ServerName php54.local PHPIniDir "C:/WAMP/PHP54" LoadModule php5_module "C:/WAMP/PHP54/php5apache2_2.dll" php_value extension_dir "C:/WAMP/PHP54/ext" <Directory "C:/WAMP/Apache/htdocs/php54"> Order allow,deny Allow from all </Directory> </VirtualHost> The PHPIniDir and LoadModule directives work fine and using phpinfo() inside my script prints the right PHP version. But I need to load extensions, and this is where it fails. php_value extension_dir should be C:/WAMP/PHP54/ext but it's (default one) C:/php. What I'm missing here? EDIT: Of course I can set this value directly in C:/WAMP/PHP54/php.ini, but I prefer passing it using vhost configuration: ; Directory in which the loadable extensions (modules) reside. ; http://php.net/extension-dir ; extension_dir = "./" ; On windows: extension_dir = "C:/WAMP/PHP54/ext"

• How do I connect to and factory reset a Catalyst 3560 Switch?

  - by Josh

  My company just bought another company. In their server room they had some older hardware, which I would like to repurpose. One of these is a Cisco Switch: C3560G-48TS-S. I found some instructions about this switch here but this is not a guide for a beginner. I have no idea how to connect to this thing to begin running the commands. It says Configure the PC terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. But I can't find anything on how to do this (assuming with telnet?) or even what program to use. I also don't know how to find the IP address of the device to connect to it. My research also says once I get in there, I need to run clear config all Is this the right command? Also, what if I can't get the username and password for these devices? Is there some way to factory reset (my only experience is with devices that have a hardware reset button) EDIT: I should note that when I push the button on the front the three lights blink, which according to the documentation indicated the switch is configured and "not available for express setup"

• Almost All Logical Volumes Disappeared - Recovery?

  - by Alex

  We had a hard disc crash of one of two hard discs in a software raid with a LVM on top. The server is running Citrix xenserver. On the hard disk which is still intact, the volume group gets detected well, but only one LV is left. (some hashes replaced by "x") # lvdisplay --- Logical volume --- LV Name /dev/VG_XenStorage-x-x-x-x-408b91acdcae/MGT VG Name VG_XenStorage-x-x-x-x-408b91acdcae LV UUID x-x-x-x-x-x-vQmZ6C LV Write Access read/write LV Status available # open 0 LV Size 4.00 MiB Current LE 1 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 root@rescue ~ # vgdisplay --- Volume group --- VG Name VG_XenStorage-x-x-x-x-408b91acdcae System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 698.62 GiB PE Size 4.00 MiB Total PE 178848 Alloc PE / Size 1 / 4.00 MiB Free PE / Size 178847 / 698.62 GiB VG UUID x-x-x-x-x-x-53w0kL I could understand if a full physical volume is lost - but why only the logical volumes? Is there any explanation for this? Is there any way to recover the logical volumes? EDIT We are here in a rescue system. The problem is that the whole server does not boot (GRUB error 22) What we are trying to do is to access the root filesystem. But everything was in the LVM. We have only this: (parted) print Model: ATA SAMSUNG HD753LJ (scsi) Disk /dev/sdb: 750GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 750GB 750GB primary boot, lvm And this 750GB LVM volume is exactly what we see on top.

• Why is my rsync so slow?

  - by iblue

  My Laptop and my workstation are both connected to a Gigabit Switch. Both are running Linux. But when I copy files with rsync, it performs badly. I get about 22 MB/s.

• disable specific PCI device at boot

  - by Rhymoid

  I've just reinstalled Debian on my Sony VAIO laptop, and my dmesg and virtual consoles all get spammed with the same messages over and over again. [ 59.662381] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 59.901732] usb 1-1.2: new high-speed USB device number 91 using ehci_hcd [ 59.917940] hub 1-1:1.0: unable to enumerate USB device on port 2 [ 60.157256] usb 1-1.2: new high-speed USB device number 92 using ehci_hcd I believe these messages are coming from an internally connected USB device, most likely the webcam (since that's the only thing that doesn't work). The only way I can seem to have it shut up (without killing my actually useful USB ports) is to disable one of the USB host controllers: # echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci_hcd/unbind This also takes down my Bluetooth interface, but I'm fine with that. I would like this setting to persist, so that I can painlessly use my virtual console again in case I need it. I want my operating system (Debian amd64) to never wake it up, but I don't know how to do this. I've tried to blacklist the module alias for the PCI device, but it seems to be ignored: $ cat /sys/bus/pci/devices/0000\:00\:1a.0/modalias pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 $ cat /etc/modprobe.d/blacklist blacklist pci:v00008086d00003B3Csv0000104Dsd00009071bc0Csc03i20 How do I ensure that this specific PCI device is never automatically activated, without disabling its driver altogether? -edit- The module was renamed recently, now the following works from userland: echo "0000:00:1a.0" > /sys/bus/pci/drivers/ehci-pci/unbind Still, I'm looking for a way to stop the kernel from binding that device in the first place.

• How do you permanently disable the 'This Connection is Untrusted' page on Firefox

  - by TheIronChef9

  I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

• How can I optimize my ajax calls to deliver at 60ms.

  - by Quintin Par

  I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

• Run 3 monitors on two different video cards?

  - by hullot

  Can I run 3 monitors on two different video cards? I have an ATI and Nvidia brand card. The ATI has 2 HDMI connections. They both work. Both cards are also picked up in Windows, one being the ATI and the other one as the Nvidia, but it says VGA Controller, although the card only takes 2 DVi. So, one DVI cable goes into that Nvidia card. 3 Monitors, but only 2 the HDMI ones from the ATI pick up, not the third one which is connected to the Nvidia via DVI. How can I run three monitors then? I suppose I can't install both drivers, so I'm unsure what to do. Is this possible? I just want the Nvidia card to power the third screen, no gaming on it, nothing. Also the ATI is picked up as primary card as well, so no hurdle there. EDIT: Hm, just installed the Nvidia drivers and it picked up the third screen no problem. Hope there aren't any major conflicts. Will post this as an answer as correct when I'm able. Can't as a new user.

• Windows 7: Dual Monitor Issue

  - by sdoca

  I have a Dell laptop with a docking station and two external monitors hooked up. I'm running Windows 7 64 bit. Originally, the two monitors were the same - Dell 1908FP. I have replaced one of them with an HP LA2405. I have set the HP 24" (1920 x 1200 connected via DVI port) as montior 1 and extended to use the Dell 19" (12080 x 1024 connected via VGA port) as monitor 2. I have set my power plan so that when the laptop is plugged in, it will turn the monitors off after 10 minutes, but it will not put my laptop to sleep. However, now that I have the HP monitor, when I unlock my laptop and the monitors come back on, all my windows are resized and shifted to the top left corner of the HP monitor as if they had been resized for display on the smaller Dell monitor. A co-worker has the exact same laptop and monitor configuration but doesn't experience this issue, so I figure there's some configuration that's different but we can't find it. I haven't been able to find any mention of a similar problem doing an internet search, but I'm not really sure what terms to use in my search. Anybody have any suggestions as to what may be causing the issue? OS setting? Monitor setting? EDIT: My laptop is using the Intel Graphics and Media Control Panel/drivers.

• How is it possible to list all folders that a particular user/group has permissions on?

  - by Lord Torgamus

  Is it possible to list all folders/files that a given group has explicit permissions on, for a machine running Windows Server 2003? If so, how? It would be nice to see inherited permissions as well, but I could do with just explicit permissions. A little background: I'm trying to update groups/permissions on a test server. One of the groups, Devs, wasn't implemented correctly when it was created, and my goal is to remove it from the system. It has been replaced by LeadDevelopers, which has permissions on many — but naturally not all — of the same folders. I want to make sure that I don't accidentally orphan any folders or cause any other issues when I remove Devs. It did have some admin-level permissions. EDIT: The answers so far — at least *cacls and AccessEnum — provide a way to find out which groups/users have permissions on known directories/files. I actually want the reverse of this behavior: I know the group, and I'm looking for the directories/files for which the group has permissions. Also, as I noted in a comment, the Devs group is not itself a member of any other group.

• Did Adobe Photoshop just killed my Graphics Card for good?

  - by user6004

  I was working with Adobe Photoshop, just some regular work, when I came to edit a PSD file and change the text of some layer, when all of a sudden the PC froze. No mouse, screen is frozen, keyboard strokes aren't getting me anything, no Task Manager, nada. So I rebooted my PC, and then something quite terrifying appeared before my eyes. It was not the Checkdisk utility that was launched, that made me terrified (by the way, that reboot damaged the partition table of an external HDD that was connected at the time to my PC, but that's another story). It was the screen itself. Please have a look. So after Checkdisk finished and Windows loaded, I noticed that the resolution was not right. Instead of 1440x900 which I had set, it was 1280x1024. When I went to change it back, I had no option to change back to my old resolution, and has only 3 other general resolution properties, as if my Video Card (GeForce 8800 GTS btw) was not recognized. And what do you know, in the Device Manager it appeared with an exclamation mark. Inside the hardware, it said this: Windows has stopped this device because it has reported problems. (Code 43) Uninstalling the drivers, downloading the newest drivers from NVIDIA and installing them did not work. It always comes back to this. So, do you have any advice before I go out and buy a new graphics card? I thought this was the only option left, but maybe the experts at Super User can help me out. By the way, the dotted screen appears after every reboot, and I see the dots when the ASUS Motherboard screen shows up at boot. Thanks in advance.
