• QuickTimeInstaller causing me buckets of issues

  - by Chadworthington

  Today I saw this message: After it installed and I rebooted, I was getting the Blue Screen of Death every few clicks. So...to resolve, I restored to a Restore Point when all was working, 2 days ago. Then, QuickTime reappeared and tried to reinstall itself. Is this iTunes related? or might it be related to Windows Live Messenger? Any suggestions on how to stop this auto installation? Update: Rolling back to a previous Restore Point temporarily fixed the issue but the patch was automatically applied a second time. Then, I made the horrible mistake of uninstalling iTunes and this caused my previous old restore point to be wiped away because of a limited amount of space that I alloted to the Windows Restore functionality. I fear that I will be faced with many issues ahead... Please help

• External speakers no longer working

  - by Mark Robinson

  We have a Windows Vista laptop. On Monday we hooked it up to external speakers, as we always do, and they worked fine. On Tuesday, we did the same but then the speakers did not work. Weirdly, the laptop internal speaker does work. Nothing was changed between Monday and Tuesday. What happened and, more importantly, how can it be fixed? BTW we tested with other speakers (and cable) and that didn't help. So it seems like a laptop issue.

• Mirroring of Apps across servers

  - by user1038814

  We wish to host multiple apps across multiple servers. What we are looking for (ideally) is an existing solution which will work. For example, normally to do it we'd follow a route (for failover) like: App is installed on one server along with mysql database App is also installed on a second server. Rsync is used to mirror the files over to the second server and ensure consistency MySQL is installed with a Master-Slave setup. We use a service such as DNS Made Easy which has a DNS failover. If one server goes down it automatically routes traffic to the backup server We have done the above a few times and generally its fine. The issue I have here is that the above is for one app. What I would like to look at is how we can manage for multiple apps and if there is a layer (such as VMWare) that has complete mirroring built in at the OS level? For example how do web hosts currently do it when they ensure that more than one machine is running a bunch of hosted websites. If you were running hosting and you had 200 clients on a server you would want the same clients across 2 or more servers and want everything mirrored. Any advice would be much appreciated.

• Drobo Pro or SAN for backups

  - by PHLiGHT

  I have multiple offices and was thinking of using two Drobo Pros as a storage location for my backups, with one at each site being synced. It seems like on the surface its a cheap alternative to a SAN. Because it will just be used for storing backups I don't think that performance is as big of an issue. Related question. How do you sync your backups from your main location to a remote site. I am using Backup Exec and wondered if I should use a feature in the program or use something like Delta Copy.

• Windows freezes, showing a random color or pattern

  - by Manu

  I have a PC with windows 7, and I'm experiencing random freezes with increasing frequency. After some time (from 30 minutes to a few hours) the screen will shows a random color or pattern (vertical lines) and nothing works anymore, I need to reboot manually. I've checked the events log, but nothing is shown except for the unexpected reboot. I've tested the RAM with Memtest86+ 4.20, and the graphics card with FurMark 1.10.3, no errors have been found. I've updated the graphic drivers and openned the case to remove dust, but the issue is still there. Also, the problem doesn't seem to arise when I'm playing games fullscreen, but when I'm surfing the web, using itunes, or coding. My hardware is as follows : intel core i5 750 CPU, ATI Radeon HD 5670 graphics card, ASUSTeK P7P55D motherboard, two 2Gb KINGSTON DDR3 ram sticks, 2 SATA hard drives, a Netgear dongle for wifi.

• Cant Add Columns to a AD Task pad except for the top level of the domain

  - by Darktux

  We are working on Active Directory taskpads application for user management in our organization and facing stange issue. When we create a taskpad, and when we are at top level of the domain, i can click view - Add/Remove Columns and add "Pre Windows Name" (and lots of other properties) to the taskpad as columns, but when i just go 1 level down , i can only see "Operating System" and "Service Pack" ; why is it happening , isnt "Domain Admins" supposed to god access to all the things in AD domain , atleast of objects they own? It is important to have "Pre Windows 2000" Name as a column begause with out that our "Shell Command" task wont show up in taskpads, since its bound to parameter "Col<9" (which is pre qindows name). Please do let me know if any additions questions to clarify my problem.

• HTTP PHP Authentication and Android

  - by edc598

  I am working on a website for which I hope to have an application for as well. Because of this, I am creating PHP API's which will go into my Database and serve specific data based on the method/function called. I want to protect these API's from misuse however, and I plan on implementing Authentication Digest to do so. However one of the OS's I want to support is Android. And I know that a malicious user would be able to reverse engineer the Android app and figure out my authentication scheme. I am left wondering: 1. Is there a better way to protect these API's from misuse? 2. Is there a way to prevent a malicious user from reverse engineering the app and potentially seeing the source code for it, enabling them to see my authentication scheme? 3. If none of these are preventable, then is my only option to have a Username/Password cred specifically for the Android app, and when eventually hacked, change the creds and issue an update for the app? I apologize if this is not the place to post such a question. Still pretty new to StackOverflow. Thanks in advance for any insight, it would be quite helpful.

• Forbid links to open new tabs in Google Chrome

  - by Andrzej

  I'm looking for a solution to forbid links in Google Chrome to open new tabs (in most cases it is a target="_blank" issue). So, I want all links to open pages in currently active tab, not in new tab. I tried a wide range of addons (for ex. "Death to target=_blank") and greasemonkey scripts that are supposed to remove target=_blank attribute but none of them worked. It is extremally anoying when I want to switch between accounts in GMail or navigate from GMail to GDrive. I always get the new tab opened and I need to close last tab manually.

• Logs show lots of user attempts from unknown IP

  - by rodling

  I lost access to my instance which I host on AWS. Keypairing stopped to work. I detached a volume and attached it to a new instance and what I found in logs was a long list of Nov 6 20:15:32 domU-12-31-39-01-7E-8A sshd[4925]: Invalid user cyrus from 210.193.52.113 Nov 6 20:15:32 domU-12-31-39-01-7E-8A sshd[4925]: input_userauth_request: invalid user cyrus [preauth] Nov 6 20:15:33 domU-12-31-39-01-7E-8A sshd[4925]: Received disconnect from 210.193.52.113: 11: Bye Bye [preauth] Where "cyrus" is changed by hundreds if not thousands of common names and items. What could this be? Brute force attack or something else malicious? I traced IP to Singapore, and I have no connection to Singapore. May thought is that this was a DoS attack since I lost access and server seemed to stop working. Im not to versed on this, but ideas and solutions for this issue are welcome.

• Windows hiding other user's files?

  - by JoshJordan

  I had a hard drive whose windows installation (running Vista) became corrupt. I bought a new hard drive, installed Windows 7, and hooked up the old drive using an external enclosure. The Users folder on the old drive shows the users that existed on the machine, but it doesn't show any of the contents of them. I assume this is due to not having the permissions I need. I have "taken control" of the folders I'm interested in, but this didn't prompt me for the original owner's password as I expected, and I still can't see the file contents. I would guess that this is a fairly common issue, but I'm not sure what to Google here. How can I get access to files in that drive's User directory?

• Terminal runs svn commands very slowly, how can I speed this up?

  - by Paul

  Spending all day in terminal is beginning to get frustrating. We're working with large CakePHP projects, including a ton of schema files and complex controllers. Whenever I go into a project, and enter svn up, or svn ci my system chokes. It takes a good 15-30 seconds before it returns what revision number I'm on. I'm running OSX 10.6 on a Macbook Pro. Any reasoning behind this? Anyway I could fix this speed issue?

• Are there any 17-20 inch monitors that support displayport?

  - by WildJoe

  I've got dual monitors now (both 20 inch 1600x1200). After seeing the new eyefinity cards out there (and reading the CodingHorror post on three monitors) I've decided to get a third. It's time to upgrade my video card anyway. Since I don't already have a third monitor and will be buying one new, I figure it'd make sense to buy one that already had a DisplayPort interface so as to avoid the adapter issue. However, I can't seem to find any monitors on newegg that support this (it's not even an option in the power search, and a keyword search turned up only adapters and video cards). A quick google showed me several 30 inchers (like Dell's, but that's way too expensive, and I don't have that much room on my desk even if I had that money) and some 22 inch models. Again, I'm looking for a 17-20 inch with a DisplayPort interface built in. Any suggestions?

• Is 10% too much for autogrow on a 4 GB sql server DB?

  - by ntsue

  I am getting the following error: 2011-03-07 21:59:35.73 spid64 Autogrow of file 'MYDB_DATA' in database 'MYDB' was cancelled by user or timed out after 16078 milliseconds. Use ALTER DATABASE to set a smaller FILEGROWTH value for this file or to explicitly set a new file size. I did some research, and I found that for large databases you should set autogrow to a fixed size (MB), and not to a percentage. I feel like this database is not large and I may not be addressing the correct issue by changing this value. Does anyone have any opinions? Thank you! EDIT: I should have specified SQL Server 2008 RC2 running on Windows Server 2008

• Conflicts between 2 NICs

  - by funbi_grace

  Hi, I have an HP server (Windows server 2003) with 2 external NICs (couldn't get the builtin NIC to work). One is for an internal network of 4 PCs and the other is for part of an Internet-facing network. Many times a day, we have to disable the internal NIC in order to get the other NIC to see the network. I know this is happening on a server, but the issue is more related to the conflicts on the NICs. Any suggestions from the community on where to look for a solution?

• Help with Abstract Factory Pattern

  - by brazc0re

  I need help with a abstract factory pattern design. This question is a continuation of: Design help with parallel process I am really confused where I should be initializing all of the settings for each type of medium (ex: RS232, TCP/IP, etc). Attached is the drawing on how I am setting up the pattern: As shown, when a medium is created, each medium imposes a ICreateMedium interface. I would assume that the Create() method also create the proper object, such as SerialPort serialPort = new SerialPort("COM1", baud); however, TCPIPMedium would have an issue with the interface because it wouldn't need to initialize a serial port object. I know I am doing something majorly wrong here. I just can't figure it out and have been stuck for a while. What I also get confused on show the interface IMedium will get access to the communication object once it is created so it can write out the appropriate byte[] packet. Any guidance would be greatly appreciated. My main goal is to have the Communicator class spit a packet out without caring which type of medium is active.

• Is it possible to use two different ErrorDocuments for different paths of a website?

  - by tapwater

  this is my first question on stackexchange and it might be a bit confusing. I currently run PmWiki (sorry, you'll have to google it, new user can only have 2 hyperlinks) at mydomain.com/pmwiki. I have a 404 page and .htaccess set up in my site's document root for 404 pages regarding anything that doesn't have to do with my wiki. By default, PmWiki handles URLs a little confusingly so I had to use this in order to get it to look like mydomain.com/pmwiki/Namespace/Page I had to create a .htaccess in /pmwiki to remove parts of the URL. PmWiki also has a custom 404 (Site/PageNotFound) page that has stopped working, now my site uses the /404.htm page. I noticed this when trying to install this "recipe" to enable case-insensitive URLs. Currently the only way to access Site/PageNotFound is by actually linking to it, and, if you read how that recipe seems to function, this is an issue. Currently mydomain.com/pmwiki/blahblah and mydomain.com/pmwiki/legitimate_namespace_but_lowercase/legitimate_lowercase_page_name both direct to mydomain.com/404.htm. I have to admit I'm very confused, and I apologize if I was unclear in any of this, but I could definitely use some help. Thanks!

• It's the ethernet 10/100 in LAN transfer faster than USB 1.0?

  - by dag729

  I have an old laptop (PIII 800MHz, with 256 RAM) that I wish to use as my home server: it'll have to serve just two people, so I think that I'll be more than ok as for the RAM and the CPU. The issue is about data, because the internal hard disk is a 12GB, that is...ridicolous! I have more than 60GB of mixed storage and counting (images, videos and music) in an external usb hd. I could put the hd in my desktop pc just to serve the big files through ethernet or let it inside its usb box attached to the laptop. The question is: which of these solutions will be the fastest? USB 1.0 attached to the server (laptop) or internal hard disk serving files via 10/100 ethernet to the laptop on demand?

• Something keeps changing the default permissions of my settings.php file for a web site on Linux

  - by JrSysAdmin

  I keep changing the file permissions for the file /var/www/html/websitename/settings.php to 775 and within 15 minutes or so it automatically changes back 555. The owner of the file is "apache" and the group ownership is for our Linux Developers just like all of the other files which are not having this issue. Obviously there must be some sort of process running that is automatically changing the file permissions (apache maybe?) but I haven't been able to figure out. Any help would be greatly appreciated.

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Record Matching Software to Compare two tables and match on % Based

  - by Crazyd

  So I have some table with Name, Address, and Zip with no record data attached; and I have a table which has all the same, but has more information and I need a way to merge the tables when they don't match 100%. How do I match them up if they aren't Identical? I'm a newb @ SQL, but I know they won't match up for the most part and I can't be the only one with this issue. However software which will do this has proven to be difficult. Writing software to do this would even be worse than having to do it in the first place. I know I can do this in excel; kinda, but with the amount of records I have its proving to be difficult over a million.

• "The requested operation could not be completed due to a file system limitation" 3202

  - by user46529

  I backup SQL Server database and it fails BACKUP DATABASE dd TO DISK = '\backupServer\backups\dd.bak' WITH COMPRESSION, CHECKSUM, NOFORMAT, INIT , BlockSize = 65536 , BufferCount = 2200 , MaxTransferSize = 4194304 The backup size is 3TB and I have 6TB free space on bacup server. I am using backup parameters per SQLCAT whitepaper. Everything works ok when I backup to local HDD and it always fails when I backup to network share. After about 6 hours. Can't find why. Thank you. Yes. The backup over the network is fastest and saves me 3Tb of local disk space :) Thanks for pointing to the memory issue. I left 4Gb to OS and it worked!

• Get-Mailbox not returning all mailboxes

  - by rotard

  I am trying to set up an exchange mailbox backup job with Vembu Storegrid and StoreGrid is unable to list the mailboxes for the client. While I was troubleshooting the issue, I did notice another thing: running the Get-Mailbox command on the mail server as the backup user only shows the mailbox for that account, while running Get-Mailbox as my admin account returns a list of what appears to be all the mailboxes. My service account is a member of "Administrators", "Domain Admins", and "Domain Users". What additional permissions might be required to list all mailboxes in the system?

• ESX Firewall Command Troubles

  - by John

  Hi, I am working on creating some firewall rules to stop some of the SSH brute-force attacks that we have seen recently on our ESX server hosts. I have tried the following rules from the CLI to first block all SSH traffic and then allow the two ranges that I am interested in: esxcfg-firewall --ipruleAdd 0.0.0.0/0,22,tcp,REJECT,"Block_SSH" esxcfg-firewall --ipruleAdd 11.130.0.0/16,22,tcp,ACCEPT,"Allow_PUBLIC_SSH" esxcfg-firewall --ipruleAdd 10.130.0.0/16,22,tcp,ACCEPT,"Allow_PRIVATE_SSH" However, these rules are not working as intended. I know that if you do not enter the block rule first, then the allow rule will not be processed. We are now having the issue where the first entered allow rule is being ignored such that the block rule works and the last entered allow rule works. I was curious if anyone had any ideas on how I could allow a few different ranges of IP's with the esxcfg-firewall --ipruleAdd command? I am at a loss and am having a hard time locating examples or further documentation about this. Thanks in advance for your help with this.

• How to bridge two networks via VPN (IPsec)?

  - by polemon

  I'd like to do a Site-to-Site bridging with VPN (IPsec), how do I do that? On the local side, I have a DrayTec Vigor2910, it is supposed to be able to manage IPsec tunnels. Anyway, I need to have several VPN tunnels to various sites, but how exactly do I do that, If the only router I can configure, is the local one? As I understand it, I'd need some sort of VPN server or client, or whatever on the other side. In any event, please clarify that issue. Thanks.
