• netlogon errors

  - by rorr

  I have two instances of mssql 2005 and am using CA XOSoft replication. The master is a failover cluster and the replica is a standalone server. They are all running Server 2003 sp2 x64. Same patch levels on all servers. This setup has worked great for several months until we recently restricted the RPC ports on both nodes of the master(5000 - 6000 using rpccfg.exe). We have to implement egress filtering, thus the limiting of the ports. We began receiving login errors for sql windows authentication and NETLOGON Event ID: 5719: This computer was not able to set up a secure session with a domain controller in domain due to the following: Not enough storage is available to process this command. This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator. We also see group policies failing to update and cluster file shares go offline at the same time. The RPC ports were set back to default when we started seeing these problems and the servers rebooted, but the problems persist. The domain controllers are not showing any errors. Running dcdiag and netdiag shows everything is fine. We have noticed that the XOSoft service ws_rep.exe is using a lot of handles(8 - 9k), about the same number that sqlserver is using. As soon as xosoft replication is stopped the login errors cease and everything functions correctly. I have opened a ticket with CA for XOSoft, but I'm not sure that the problem is actually xosoft, but that it is the one bringing the problem to light. I'm looking for tips on debugging RPC problems. Specifically on limiting the ports and then reverting the changes.

• Wifi network undetectable on a Lenovo G470

  - by Rex

  I have a WPA2 secured network with a visible SSID at home that works perfectly fine with a Dell laptop,a HP netbook and sundry mobile phones. When I try connecting my sister's Lenovo G470, it refuses to detect the wifi network no matter what, but shows up the neighbors' networks. The Lenovo also works correctly at her office. Both laptops run Windows 7. Already tried/checked the following: Manually configure wifi network settings (copied over from the Dell) Ensure there is no MAC address filtering on the router. Ensure router DHCP server is not running out of addresses to assign (I have set it to allocate upto 10). Reboot laptop, router etc. Is this a known problem, and is there anything else one could try? Update - The problematic Lenovo uses Windows 7 Home Basic while the Dell that works uses Home Premium and the HP netbook uses Starter edition - if that makes any difference. Further update - It is able to connect if I reboot into safe mode with networking. However in 'normal' mode it shows up the network sporadically, and then says there was an error connecting to it. All the network parameters, password, encryption, etc etc are EXACTLY the same as they are on the Dell.

• Windows 7 and laptop overheating

  - by Nikola

  I am using ArchLinux 99% of my working time, and laptop has absolutely no heating problems. But when it comes to using Windows 7, laptop starts heating and one can clearly hear CPU fan working like crazy. I think it has something to do with CPU itself, because on Linux I can simply manipulate with CPU governors (eg. set it to ondemand), but I can't seem to find any similar software to do the same thing as if in Linux. Or, the heating might be caused because of two graphics cards or something? CPU-Z results http://valid.canardpc.com/show_oc.php?id=2310815 Any idea/solution regarding this issue?

• Does WebDAV even work on IIS 7? I say nay

  - by FlavorScape

  I've tried every configuration from the top 10 stack overflow and server fault results for WebDAV 405 on IIS (for verb PROPFIND and PUT). I'm running server 2008 SP2. Followed all the instructions here. I'm no stranger to configuring servers. This has gotten nowhere after 8 hours. Confirmed system.webserver in applicationhost.config: <add name="WebDAV" path="*" verb="PROPFIND,PROPPATCH,MKCOL,PUT,COPY,DELETE,MOVE,LOCK,UNLOCK" modules="WebDAVModule" resourceType="Unspecified" requireAccess="None" /> Port 443 with basic auth, same issue. Tried port 80 with windows auth. Broken. (405) Windows authentication. Check. Added authoring rules for default site and application. Check. Not the firewall. Check. added "Desktop Experience" role feature Tried HTTPS with Basic Authentication on port 443. Does not work. No other services are running like Sharepoint. Check. confirmed user has read/write NT level permissions for the folder/virtual dir tried net use * http://localhost /user:MYDOMAIN\me myPass get error 1920, if I don't authenticate I get error 67 confirmed I'm not applying filtering to WebDAV: <requestFiltering> <fileExtensions applyToWebDAV="false" /> <verbs applyToWebDAV="false" /> <hiddenSegments applyToWebDAV="false" /> 405 - HTTP verb used to access this page is not allowed.

• How can you invert the colors of a PDF?

  - by legr3c

  I need to invert all the colors of a PDF document (background, text, graphics, and images). I want it persistent in the file so the inverted viewing options, that some viewers offer, won't help. Rasterizing the document and using image manipulation software is also not an option. I read somewhere that this can be done with the Enfocus PitStop plugin for Acrobat. However I didn't see a corresponding command anywhere. Am I missing something? Then I read that the ARTS PDF Crackerjack plugin for Acrobat offers negative printing so I tried that, too. The option is there but it simply doesn't work. I have been searching for very long for a way to do this. It seems like a common enough task but I just can't find out how to do it. Are there maybe any virtual printer drivers or something of the sort that support negative printing? Can anyone help?

• How to black out second monitor when playing a full screen game?

  - by Gary

  I've got two monitors. When I play a full screen game in my primary monitor, the second monitor still shows the Windows desktop. How can I black out the second monitor so that it doesn't show anything at all? My graphics card is from ATI. I'm running Windows 7 in Boot Camp on an iMac. I don't know if this makes a difference, however, as any solution to my question will do, really. For instance, is there a tiny app that I could run to disable the second monitor for a while? I'd rather not have to open Windows display settings every time I run a game and disable the monitor that way, though.

• Word 2010 not printing body text on pages with images

  - by Oesor

  I've got a document exhibiting bizarre behavior -- when I print, the body text style is only displayed on pages without images. Headings, header and footer, and captions are printing on the page, along with any graphics such as border styles applied to the style, but the text itself doesn't print -- except for en dashes. The text is pretty basic -- a justified Calibri style. Images are their own style, a centered paragraph item. There's no floating image boxes or text boxes going on, everything's a paragraph style. It's not a print driver issue. I get identical behavior on both a HP and Brother laser printer. It's also not a paragraph-level style issue; I've inserted enough dummy text to move a printing paragraph on a page with no images to the next page, which has an image, and the paragraph does not print on the next page. Has anyone run into an issue like this and knows the solution?

• Black screen on Ubuntu 12.04

  - by user1648371

  I've just upgraded to Ubuntu 12.04 and I'm experiencing some problems. The first thing I noticed is that when I click the Workspace switcher all I get is a black screen (I can guess where the different workspaces are located and clicked on them, not a practical solution though). In addition when I lock the screen or suspend the laptop (a Vaio VPCEB4M1E) I get a shifted screen (I see the right most vertical stripe on the left size of the monitor and nothing about all the rest, to put it clearly I can see the gear that allows me to turn the pc off, etc, but not much more..) when I go to the additional driver menu I see the "ATI/AMD proprietary FGLRX graphics driver" are installed and the post-release update version is available. I don't know if the problem is driver related, so before doing anything I'd like to get some suggestions from you guys. Thanks you!

• Server 2008 R2 How to Change Windows 7 Basic Theme Color

  - by Wes Sayeed

  We're deploying thin clients connecting to a terminal server farm. The computers have high visibility to the public and I would like them to at least look presentable and not like something out of 1995. So I installed the Desktop Experience feature and enabled the Theme service. The server will not support Aero because it has no 3D graphics, but we can enable the Windows 7 Basic theme, which has the Aero look without the 3D effects. The problem with that theme is that you can select any window color you want, as long as it's baby boy blue. Is there a way to make those windows another color? The window color controls do nothing.

• How to change image to this color?

  - by askmoo

  I have this image And I need to change it to the color #D21108 (type of RED). Of course, I do not want to paint it to this color, but to change the color to #D21108 and its shades (like I do in Photoshop via Brush Colour Replacement). I have all info about this color, values of RGB, CMYK, Lab and HSV if you need them. Now, I guess I can easily change it via GIMP's menu "Colors". I tried options Color Balance, Hue-Saturation, Colorize, but I did not find a way to enter the starting color I need. I was closest to my aim via Hue-Saturation, but I could not get this red value, no matter what I tried. As I am not a graphics expert, please tell me how to accomplish this task. PS. What's the meaning of Lab and HSV in the color scheme? I know the meaning of RGB and CMYK.

• vector quality of svg and pdf

  - by Kasper

  I'm converting pdf files to svg as it is easier to use svg files on webpages. I first thought the quality of svg must be similar to pdf, as they are both vector graphics. However, now I look a little better on it, it seems that pdf is a bit superior: (https://dl.dropboxusercontent.com/u/58922976/Photos/1.png) I wonder if I could change this in some way. Is this because pdf vectors are just better quality ? Or is this because chrome renders svg in lower quality than adobe reader renders pdf ? Is this a setting in the svg file that I could change ? Here is the pdf file: https://dl.dropboxusercontent.com/u/58922976/syllabusLinAlg2012.59.pdf And here is the svg file: (https://dl.dropboxusercontent.com/u/58922976/syllabusLinAlg2012.59.svg) I've made this svg file in illustrator, and only chrome is able to use the embedded svg fonts. So firefox and internet explorer won't give the expected result.

• Why does 1080p through a VGA cable fit my HDTV but is oversized when through an HDMI cable?

  - by GraemeF

  I have put together a new PC with a XFX GeForce GTX 260 graphics card and have it connected to my HDTV. First, I used an old VGA cable with a DVI to VGA adapter and plugged it in to my HDTV's VGA port. Running at 1920x1080 it fit the screen perfectly. Now, to avoid running another cable across the room, I have connected it with a DVI to HDMI cable to my TV's HDMI port, and the desktop at 1920x1080 is cropped by the edge of the screen. I have "fixed" the cropping by using NVIDIA's "Adjust desktop size and position" tool, which created a screen resolution of 1814x1022 to fit the screen, but this is no longer the TV's native resolution and confuses some software (e.g. WoW). Why does VGA work as expected, but HDMI is scaled up? Can it be avoided?

• How do I make Linux recognize a new SATA /dev/sda drive I hot swapped in without rebooting?

• suggestions for firewall/router project using *BSD or Linux

  - by Adeodatus

  Hi All, I have a project in mind and I'd love to hear some ideas on some open source solutions with COTS hardware. I have a few 24 and/or 48 port managed layer2 switches with customers potentially on each port (though its usually about 20-30). Right now the switch has a bridged network and backhaul the traffic to our core to a centralized DHCP server. I need to move them to a NAT solution and, while doing this, I'd like to protect the customers on each port from the customer traffic on the other ports. I also need to be able to port forward from the public side of the firewall/nat box to specific hardware on the inside of the nat machine (easy enough, I know). My first thoughts are to build an appliance-like box (the fewer moving parts the better) that can do filtering and NAT with rfc1918 an address range being handed out via a DHCP server on the appliance. A caching DNS server on the appliance would be a plus since we backhaul everything to the core. I'd like to run FreeBSD but I'm open. Now, to try to limit the broadcast traffic thats visible I was thinking of doing each port on the switch as a different vlan and have the switch do trunking to the private NIC on the FreeBSD/appliance. I'd probably need to do some magic on the freebsd NIC to get this working but it should. We have the parts to build these systems. So, does this make sense? Are there any other solutions out there that we don't have to spend money on but can use our parts to create something? Are there any good distros that could do this already (monowall)?? I may or may not admin this solution so a secure web configuration and management tool would be a plus in the other admins' minds. Thoughts?

• Redirecting X output

  - by Adam Matan

  Hi, I have a small program that checks some elements of a web service. The program shows graphics output and displays commmand-line results as well. I have been trying to automate this program to run periodically on a server in my office. Problem is, It only works when I have X enabled - either directly on the server, or via ssh -X. Following Google, I have tried Xvfb, which gave me quite cryptic error message: Xvfb :1 -screen 0 1600x1200x32 Fatal server error: Server is already active for display 1 If this server is no longer running, remove /tmp/.X1-lock and start again. Any ideas how to run it? I'm actually looking for the X equivalent of &>/dev/null... Thanks in advance, Adam

• I install Ubuntu 13.10 and reboot and im on KDE desktop?

  - by jgamer578

  Hi I'm Jacob and I have no idea what's going on. I installed Ubuntu 13.10 today and was playing around with it for a while and dl'd a bunch of apps from software center and stuff. Eventually I installed steam and (finally) got it working. I downloaded TF2 and had some weird issue where the screen got so distorted to the point I could not play. So I dl'd a driver for my graphics card from the additional drivers app (or whatever it's called) and when it was done I restarted my computer (because it said to.) When the PC booted up it loaded the KDE desktop and I have no idea why. I had unity before I rebooted. Ubuntu 13.10 is the only OS installed on my PC, and I still have all the apps that I downloaded, but I kinda like unity (I started using Ubuntu after they switched to unity) and want it back. Thanks for reading and any help in advance, Jacob.

• Advice needed for a home network setup (hardware & software) to handle many clients and potentially heavy traffic

  - by posdef

  I have recently decided to re-structure the home network of our flatshare here. Here's a quick outline of the situation. I envision to have the following 4 devices connected to the router via cable: Xbox 360 IP phone Printer QNAP server (Web, File and Multimedia) We are three people living here, so on top of that there will be to 5-6 computers/mobile devices connecting as wireless clients. My goal is to be able to transfer files (when needed) between the computer and the Multimedia server, which I can reach via 360 and play on the TV. I also would like to keep a high level of security; right now I have the encryption on WPA2 and MAC filtering. I don't believe the web server will get heavy traffic, though I would like to have it responsive. Likewise, I don't have a habit of downloading via torrent etc, but I greatly appreciate my network being responsive and fast, especially when I am browsing or streaming high quality media. Now my questions are: is this setup feasible? smart? efficient? can this be improved somehow? my current router (D-Link DI624) and the previous one (DI-524) used to have spontaneous drops in network, which I find highly irritating. I don't believe in my router, especially now that it completely crashed when I was test-running the setup by transferring a large media file to server while xbox was playing music from the server, and two computers browsing the net. Do I need to get new hardware, if so, any recommendations for a reliable and fast router?

• Hyper-V performance comparisons vs physical client?

  - by rwmnau

  Are there any comparisons between Hyper-V client machines and their physical equivalent? I've looked around and can find 4000 articles about improving Hyper-V performance, but I can't find any that actually do a side-by-side comparison or give benchmarking numbers. Ideally, I'm interested in a comparison of CPU, memory, disk, and graphics performance between something like the following: Some powerful workstation (with plenty of RAM) with Windows 7 installed on it directly Same exact worksation with Hyper-V Server 2008 R2 (the bare Server role) and a full-screen Windows 7 client machine Virtual Server 2005 had performance that didn't compare at all with actual hardware, but with the advances in CPU and hardware-level virtualization, has performance improved significantly? How obvious would it be to a user of the two above scenarios that one of them was virtualized, and does anybody know of actual benchmarking of this type?

• Ho to make Histogram Normalize and Equalize in java using JAI library?

  - by Jay

  I m making App in java using Swing component and JAI library. I make histogram of black and white or gray scale image.Is this method of making histogram correct? iif it is correct then how can i do normalization and Equalization of histogram in my App in java using JAI library?my code is below. in my code i make BufferedImage object and then make and plot histogram of that image . enter code here import java.awt.Color; import java.awt.Graphics; import java.awt.image.BufferedImage; import java.io.IOException; import javax.media.jai.JAI; import javax.media.jai.PlanarImage; import javax.swing.*; public class FinalHistogram extends JPanel { static int[] bins = new int[256]; static int[] newBins = new int[256]; static int x1 = 0, y1 = 0; static PlanarImage image = JAI.create("fileload", "alp_finger.tiff"); static BufferedImage bi = image.getAsBufferedImage(); FinalHistogram(int[] pbins) { for (int i = 0; i < 256; i++) { bins[i] = pbins[i]; newBins[i] = 0; } repaint(); } @Override protected void paintComponent(Graphics g) { for (int i = 0; i < 256; i++) { g.drawLine(150 + i, 300, 150 + i, 300 - (bins[i] / 300)); if (i == 0 || i == 255) { String sr = new Integer((i)).toString(); g.drawString(sr, 150 + i, 305); } System.out.println("bin[" + i + "]===" + bins[i]); } } public static void main(String[] args) throws IOException { int[] sbins = new int[256]; int pixel = 0; int k = 0; for (int x = 0; x < bi.getWidth(); x++) { for (int y = 0; y < bi.getHeight(); y++) { pixel = bi.getRaster().getSample(x, y, 0); k = (int) (pixel / 256); sbins[k]++; //pixel = bi.getRGB(x, y) & 0x000000ff; //k=pixel; //int[] pixels = m_image.getRGB(0, 0, m_image.getWidth(), m_image.getHeight(), null, 0, m_image.getWidth()); //short currentValue = 0; //int red,green,blue; //for(int i = 0; i<pixels.length; i++){ //red = (pixels[i] >> 16) & 0x000000FF; //green = (pixels[i] >>8 ) & 0x000000FF; //blue = pixels[i] & 0x000000FF; //currentValue = (short)((red + green + blue) / 3); //Current value gives the average //Disregard the alpha //assert(currentValue >= 0 && currentValue <= 255); //Something is awfully wrong if this goes off... //m_histogramArray[currentValue] += 1; //Increment the specific value of the array //} } } JTabbedPane jtp = new JTabbedPane(); jtp.addTab("Histogram", new JScrollPane(new FinalHistogram(sbins))); JFrame frame = new JFrame(); frame.setSize(500, 500); frame.add(new JScrollPane(jtp)); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

• Windows Server 2003 R2 Standard: Locks MS Office files, but not Adobe .AI and .PSD files?

  - by Bruce Garlock

  We have some shares setup on a Windows 2003 R2 server, and the MS Office files people save behave properly: The first person to open the file gets read/write, and the second person to open the file while the first person still has the file open, gets a read-only version. This is not true for the graphics files, like Adobe Illustrator .AI files, and Photoshop .PSD files. Anyone who goes to open these files has full read/write, even if someone else is already working on the file! This has lead to numerous file corruption issues, as well as other lost work, since it always saves the last changes to the file. How do we get Windows to properly lock these files so when someone is working on a file, and someone else wants to open one, they get read-only access? Many thanks, Bruce

• Querying a CSV file

  - by sheepsimulator

  Does anyone know of a simple tool that will open up a CSV file and let you do basic, SQLesque queries on it? Like a graphical tool of sorts, one that is easy to use. I know I could write a small script to do an import of the CSV into a SQLite database, but since I imagine someone else thought of this before me, I just wanted to inquire if one existed. What's prompting this question is I am getting frustrated with Excel's limited filtering capabilities. Perhaps some other data visualization manipulation tool would provide similar functionality. Free or OSS is preferred, but I'm open to any suggestions. EDIT: I really would prefer some clear tutorials on how to do the below instead of just "make your sheet an ODBC entry" or "write programs using ODBC files", or more ideas on apps to use. Note: I cannot use MS Access. Yet another EDIT: I'm still open for solutions using SQLite. My platform is a semi-ancient Win2k laptop, with a P4 on it. It's quite slow, so a resource-light solution is ideal and would likely get the win.

• X locks up with konqueror on comics.com

  - by retracile

  If I browse to comics.com using konqueror under KDE on Fedora 11, X will, after a delay, lock up. The mouse will move, but no keyboard input is recognized, and the screen does not react to the mouse passing over objects on screen. I am able to ssh into the machine and issue shutdown -r now and have that work. The machine is a Dell XPS M1330 with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c), and Fedora 11 is fully updated. Visiting the same site in Firefox does not cause a lockup. I am booting with nomodeset since it won't boot into X otherwise. I tried the other two accel options: EXA (still locks up) and XAA (X won't start). Any suggestions on how I can debug this? bugzilla

• How can I get 32-bit Direct3D working on my 64-bit Windows 7 system?

  - by Daniel Stutzbach

  I recently upgraded a Dell Inspiron 6400 to Windows 7 Ultimate 64-bit. I have a 32-bit 3D application that refuses to run, giving an error of "Failed to initialise [sic] Direct3D device". The dxdiag tool tells me: DirectDraw Acceleration: Enabled Direct3D Acceleration: Not Available However, the 64-bit version of dxdiag tells me: DirectDraw Acceleration: Enabled Direct3D: Enabled I have installed and re-installed the latest graphics drivers, as well as the DirectX 9 redistributable, but it stills fails in the same way. dxdiag reports the chipset name as the "Mobile Intel(R) 945 Express Chipset Family" with the the Chip Type as "Intel(R) GMA 950". The main driver is igdumd64.dll, version 8.15.10.1930. How can I get 32-bit Direct3D working?
