• Windows 7 login screen show only last user and "Other User" icons after profile problem.

  - by Mike Thompson

  I recently had a profile problem with my Windows 7 PC. My original profile in the registry had ".bak" appended to it and a new profile was created. I was unable to login with the new profile. I fixed this immediate problem by logging on in safe mode. This enabled me to restore my original profile. However, since that moment the login screen now operates differently. Instead of showing icons for all the users with accounts on the PC, it now only shows two icons. The first icon is the last user who logged on and the second icon always shows "Other User". I have tried several different solutions recommended by other people with similar problems, but none of them have fixed the problem. I think the person who started this thread has the same problem, but none of the proposed solutions helped him either. Any help much appreciated.

• Task bar remains visible with "Auto-hide the task bar" checked in Windows 7.

  - by Corey

  It's about time that I figure this out. I can say with a pretty high confidence that I have experienced this issue in all consumer versions of Windows since XP. I keep "Auto-hide the task bar" checked to maximize screen real estate. Every once in a while, the task bar will refuse to hide while individual windows will continue to act as if that option is checked (by falling under the task bar). For years, I have fixed this by rebooting. Of course, I cannot predict the timing or frequency of the problem, so the process becomes burdensome. I want to know how this can be fixed without rebooting. It has affected my on multiple machines using multiple versions of Windows, so I cannot be the only one who is bothered by it. Can anyone help me solve this?

• Why a SIGHUP signal to httpd kills the tomcat process?

  - by Geo

  I have a server with a tomcat process binding to port 80 and a httpd processes binding to port 5000. For some reason every time any process send a SIGHUP signal to httpd process my tomcat process disappears without error or anything. I fixed the issue on the server the following way, added an explicit ServerName directive in the httpd.conf and that fixed the issue. I still don't understand why the SIGHUP to httpd killed the tomcat process. NOTE 1: I replicated the kill signal with the following command: find out what the httpd pid is. cat /etc/httpd/run/httpd.pid 4056 then kill with a sighup signal kill -s SIGHUP 4056 NOTE 2: We troubleshoot the issue and find that logrotate running every morning at 4am was sending a SIGHUP signal to realease the logs to be able to rotate them, thus killing tomcat as well.

• Keyboard doesn't load in windows xp after Alureon infection

  - by alureonissue

  AVAST detected alureon in a number of system files including atapi.sys and kbdclass.sys iple I quarantined those files, and restarted my machine. After restarting, my keyboard and cdrom did not work (I assumed those drivers would be automatically replaced, but was apparently wrong.) I went into device manager, and checked for hardware changes, it fixed the cdrom (which works now) and looked as though it fixed the keyboard as well. It did not. After multiple reboots the keyboard is still not recognized. It works up until the XP login screen loads, after which it is completely unresponsive. Any advice would be appreciated. Thanks :)

• Calculating Cloud Service Costs [closed]

  - by capdragon

  Possible Duplicate: Can you help me with my capacity planning? I would like to scale a web application to the Cloud and wanted to know if anyone had any experience calculating costs and could tell me how I would go about that. I have NO experience with cloud services at all. Currently my production environment consists of two web servers and one database server. If the application continues on a linear growth path, eventually, I want to scale to the cloud to avoid any more long term commitments to extra hardware. I want to be able to create a similar environment I have now as a baseline. Have this as my fixed cost that I will always have. I also want to calculate my variable costs that will increase with more users or bandwidth. I don't have a preferred cloud vendor. Amazon, Rackspace, Terremark or any other is fine as long as understand how to calculate my fixed and variable costs.

• Forms authentication failed between web server and sql server

  - by Matt Bear

  I've actually found the solution, but I'm trying to understand why it failed, and why my solution fixed the problem. We have an application that uses forms authentication between a web server and sql server, web server runs server 2008, sql server runs 2008 r2, and sql server 2008. In august the sql server was patched with .net 3.5.1, the web server was untouched, and the forms authentication continued to work. 1 week ago we virtualized the web server onto our vSphere server because of failing hardware. Afterwards the form authentication failed with event code 4005, detail code 50201, The ticket supplied was invalid (on the sql server). In fact the sql server started generating Schannel errors and began blue screening 3-4 times a day. At this point I touched the sql server for the first time(ever), the errors were non specific, any reference to them I could find had to do with either zone alarm(which we don't run), or memory errors. So I applied service pack 1, which stopped the blue screening, but did not fix the forms authentication. At this point we had a work around, so we put it on the back burner while we completed another project, and I was able to get back on it last night. First thing was to adjust some code in the webconfig file on the sql server, nothing, next was regenerate and change out the machine key, still no change. Update the DNS servers, no change. Finally I went through and installed all windows updates, two reboots, (over RDP installed a network card driver which failed, and did not have my server room key, that was fun). After that, forms authentication was working again. And the sql server stopped generating as many errors, I've gotten two schannel errors since then. In short, forms authentication began failing when the web server was cloned onto a virtual machine, which caused the sql server to blue sceen? and forms authentication to fail. And could only be fixed by applying patches to the sql server?(I'm wishing I had patched the servers one at a time so I could know for sure which patch on which server fixed it). My question is why did it fail, and why did patching fix it? I hate fixing something without fully understanding the why and how.

• Multi-monitor aterm transparency

  - by Bryan Ward

  I have 3 monitors which I set the background with using xpmroot my-5760x1200bg.png I then setup aterm to use transparency by adding the following to my ~/.Xdefaults file. aterm*transparent:true aterm*shading:60 aterm*background:Black aterm*foreground:White aterm*scrollBar:true aterm*scrollBar_right:true aterm*transpscrollbar:true aterm*saveLines:32767 aterm*font:*-*-fixed-medium-r-normal--*-140-*-*-*-*-iso8859-1 aterm*boldFont:*-*-fixed-bold-r-normal--*-*-140-*-*-*-*-iso8859-1 I am getting transparency on my aterm windows, but the image that is coming through with the transparency isn't correct. On the left monitor things are fine, but the middle and right monitors both seem to use the leftmost 1920x1200 of the background image as what is behind the terminal window. It would be as if every screen had the same background as the monitor on the left. Is this something that can be configured to be correct, or is this a bug? I'm running Gentoo Linux with Xmonad.

• Excel 2007: Using a time to set XY chart axis scaling like in 2003

  - by CookieOfFortune

  In Excel 2003, when you created a XY chart using time as an axis, you could set the scaling of these axes by typing in the date. In Excel 2007, you have to use the decimal version of the time (eg. How many days since some arbitrary earlier date). I was wondering if there was a way to avoid having to make such a calculation? A developer posted on a blog that this issue would be fixed in a future release, but all versions of Excel 2007 I have tried have not resolved this issue. The relevant quote: Those of you familiar with this technique of converting time to a decimal may recall that Excel 2003 allowed you to enter a date and time like “1/1/07 11:00 AM” directly in the axis option min/max fields and Excel would calculate the appropriate decimal representation. This currently does not work in Excel 2007 but will be fixed in a subsequent release.

• catch-22 with apt-get

  - by Mark J Seger

  I'd recently installed a package and discovered my scp stopped working. After removing and installing some things I got it fixed but then I stated getting errors in apt-get about dpkg: error: configuration error: /etc/dpkg/dpkg.cfg.d/multiarch:1: unknown option 'foreign-architecture' so I commented it out and thought that fixed the problem until I discovered the chrome icon in my launcher turned into a ? and chrome no longer worked. I tried to reinstall it and got the apt-get error: "ambiguous package name 'libglib2.0-0' with more than one installed instance" if I try to remove libglib2 I get the error The following packages have unmet dependencies: iceape-browser : Depends: iceape but it is not going to be installed iceape-chatzilla : Depends: iceape (>= 2.7.11) but it is not going to be installed Depends: iceape (<= 2.7.11-1.1~) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. so then I tried to remove icape-browser and it complained about the 2 instances of libglinb2. in fact virtually any command I issue does the same thing so I don't know what I can do to untangle things.

• Do RAID controllers commonly have SATA drive brand compatibility issues?

  - by Jeff Atwood

  We've struggled with the RAID controller in our database server, a Lenovo ThinkServer RD120. It is a rebranded Adaptec that Lenovo / IBM dubs the ServeRAID 8k. We have patched this ServeRAID 8k up to the very latest and greatest: RAID bios version RAID backplane bios version Windows Server 2008 driver This RAID controller has had multiple critical BIOS updates even in the short 4 month time we've owned it, and the change history is just.. well, scary. We've tried both write-back and write-through strategies on the logical RAID drives. We still get intermittent I/O errors under heavy disk activity. They are not common, but serious when they happen, as they cause SQL Server 2008 I/O timeouts and sometimes failure of SQL connection pools. We were at the end of our rope troubleshooting this problem. Short of hardcore stuff like replacing the entire server, or replacing the RAID hardware, we were getting desperate. When I first got the server, I had a problem where drive bay #6 wasn't recognized. Switching out hard drives to a different brand, strangely, fixed this -- and updating the RAID BIOS (for the first of many times) fixed it permanently, so I was able to use the original "incompatible" drive in bay 6. On a hunch, I began to assume that the Western Digital SATA hard drives I chose were somehow incompatible with the ServeRAID 8k controller. Buying 6 new hard drives was one of the cheaper options on the table, so I went for 6 Hitachi (aka IBM, aka Lenovo) hard drives under the theory that an IBM/Lenovo RAID controller is more likely to work with the drives it's typically sold with. Looks like that hunch paid off -- we've been through three of our heaviest load days (mon,tue,wed) without a single I/O error of any kind. Prior to this we regularly had at least one I/O "event" in this time frame. It sure looks like switching brands of hard drive has fixed our intermittent RAID I/O problems! While I understand that IBM/Lenovo probably tests their RAID controller exclusively with their own brand of hard drives, I'm disturbed that a RAID controller would have such subtle I/O problems with particular brands of hard drives. So my question is, is this sort of SATA drive incompatibility common with RAID controllers? Are there some brands of drives that work better than others, or are "validated" against particular RAID controller? I had sort of assumed that all commodity SATA hard drives were alike and would work reasonably well in any given RAID controller (of sufficient quality).

• Can't bring NAT to work

  - by user31738

  Hello, I bought a D-link DIR-300 wireless router and i can't bring NAT to work, i have an ssh and http service i need to forward to the internet. My connection is as follows: I have an ADSL connection, i'm using a ADSL ethernet modem connected and working, it doesnt let me put it on bridge mode. I have my router connected to my adsl modem through ethernet, it gets its ip through DHCP (and i'ts always the same) I have a desktop computer running linux with apache and openssh configured and working, it has fixed ip. I configured the NAT in the modem forwarding port 22 from the router ip to the internet. In the router i setup NAT forwarding port 22 from the desktop computer fixed ip to out there. This setup already worked with a fonera i had before, can anyone help me with this or tell me what kind of tests do i need to do? How can i test if the router is forwarding ports correctly before the modem?

• Do all the network cards use the same frequency to send signals to wire?

  - by smwikipedia

  I am comparing my cable TV wire to my network wire. In a TV cable wire, different frequencies are used by different TV channels. And since a certain channel use a fixed frequency, I think the only left way to represent different signal is with the carrier wave's amplitude. But what about the network wire? For all the network cards with the same type, do they also use different frequencies to send signals just like TV cable? I vaguely remember that they use frequency adjustment to represent signals. So the frequency should not be a fixed one. So how did all the network cards that sharing the same medium differentiate their own signal from others?

• Cannot move Google Chrome tabs to different monitor in ubuntu

  - by Moses

  When I use Chrome in Windows, I can grab a tab and drag it over to my second monitor and it will automatically maximize. In ubuntu, when I try to do the same, the tab will snap back to my primary monitor and maximize there. There is a related bug report for Chromium that is labeled "fixed" here, but when I try using Chromium instead of Chrome, I get the same behavior (not what I called fixed). So far the only other thing I've tried is changing themes, resetting Chrome's settings to default and tested Chromium as I pointed out above. I've also tried installing Chrome from a live Linux disc, and the behavior is still the same. The issue does not occur with Firefox, but I need to use Chrome for work-related reasons, so simply switching isn't really an option personally (though it is a viable workaround). I'm using Chrome 30 and ubuntu 13.04. Does anyone have any solutions?

• How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

  - by David Siegel

  How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

• Blocked connections passing through firewall. What is wrong?

  - by Kiranu

  In our company we have a small business router (Cisco RV082) on which we are using its standard configuration (block all incoming traffic). We also have an SMTP relay configured (using WS2008R2) so that our internal applications can send email through google apps (which requires authentication). The thing is that the server was being used to send spam. We fixed the problem by only allowing the server to relay email from our internal IP address range (10.0.0.0/16). My concern is that there was a way by which external IPs connected to the network and that underlying problem has not been fixed, but I cannot imagine how these machines connected. Any thoughts?

• Howto maintain an EXT3 filesystem

  - by Reinoud van Santen

  Lately I had several servers which encountered a write error on an EXT3 filesystem and as a result of that remounted the filesystem read-only. Understandably on a production server this causes severe problems. On a reboot the filesystem where fixed but on large partitions this takes a lot of time. After the filesystem was fixed, correcting several errors, the server runs well again. What can I do to minimize the rate at which this happens? I can't seem to find much information on periodically checking the filesystem(s) on a running server. Is it possible to change the way in which EXT3 / the system handles write errors? What would be a sane solution. All servers which this is regarding to are running CentOS Linux 5.4 or 5.5.

• File property information (last write time and file size) in explorer out of date by hours over netw

  - by David L Morris

  An application is running on a windows XP prof machine picking up file from a network share from another windows machine. It detects that the file has been updated (by date and time or optionally file size) and reads it for any new data. Most of the time the last write time and file size, seems to be up to date. Occasionally, this information stops being updated, even though the file is growing (intermittently during the day) with appended content, so that the last write time and file size remain fixed at some arbitrary moment. This is visible in explorer, where it shows a fixed last write time on the reading machine. Just opening the file to edit it in notepad, immediately refreshes the file properties, and the other application picks up where it left of. The file location can't be changed, nor the location of the relevant applications. Any solutions to resolve this problem?

• Website visitors are still being redirected after "fixing" the damage from a conditional redirect website attack

  - by Shannon

  BACKGROUND A website of mine was recently the target of a conditional redirect attack. PHP code was added to my pages to redirect visitors. The .htaccess file was edited to redirect visitors. I've re-uploaded my website so the compromised PHP and .htaccess code have both been removed. My site is mostly handwritten php and static HTML content. I don't use page comments or any third party libraries. THE PROBLEM After removing the compromised php and htaccess files, visitors are still being re-directed. What could be the reason that visitors are still being redirected? Are there any tools to check where/how redirects are taking place so I can debug the problem? UPDATE - PROBLEM FIXED As suggested in the comments, I cleared my Firefox cache and that fixed the problem (for me anyway). Visitors with old cache data will obviously still be re-directed.

• Which built-in account is used for Anonymous Authentication in IIS 7?

  - by smwikipedia

  We know that Microsoft IIS 7.0 offer a slew of authentication methods such as Anonymous Authentication, Form Based Authentication, Digest Authentication, etc. I read from Professional IIS 7 published by Wrox that: When we use Anonymous Authentication, the end-user does not supply credentials, effectively mak- ing an anonymous request. IIS 7.0 impersonates a fixed user account when attempting to process the request (for example, to read the file off the hard disk). So, what is the fixed user account impersonated by IIS? Where can I see it? If I don't know what this account is, how could I assign proper permissions for the clients who are authenticated as anonymous users? Thanks.

• Can Ping but Cannot Telnet directly to SQL Server 2012 Cluster Nodes

  - by tresstylez

  We have a monitoring tool (Solarwinds Orion) that needs to connect to a 2-node failover SQL Server Cluster. For reasons outside of our control -- we cannot monitor the CLUSTER IP directly at this time, so we have fallen back to monitoring each cluster node IP directly. This is not working. Upon troubleshooting, we tried to test that the cluster node was listening on the proper (fixed) port by using telnet to the cluster node IP/port -- and the telnet failed. However, telnet'ing to the Cluster IP/Port was SUCCESSFUL! Each node has its own IP. Each node is listening on the identical FIXED port. Each node has Dynamic Ports disabled. Each node can be PINGED successfully from the monitoring tool. Windows Firewall is DISABLED. How can I troubleshoot why I cannot telnet to the listening port on the cluster nodes?
