• IIS 7.5 FTP Service crashes after installation of Advanced Logging 1.0 Module

  - by Jeremy

  I've recently been tasked with setting up two new productions servers for an ASP.Net application. The servers sit behind a F5 Load Balancer, which in turn forwards the end users IP address forward via the standard X_Forwarded_For HTTP Header. All of the reading that I have done suggests that I need to install the IIS Advanced Logging Module in order to take advantage of the X_Forwarded_For HTTP Header. Some quick background: Both of the web servers are Windows 2008 R2 Standard (x64), with IIS 7.5 installed and configured. The FTP Role has also been installed, configured and is operational. The Issue After installing the IIS Advanced Logging module via the Web Platform Installer, I noticed the following Error in the Event Viewer: The FTP Service encountered an error trying to read configuration data from file \?\C:\Windows\system32\inetsrv\config\applicationHost.config, line number 374. The error message is: Unrecognized element 'advancedLogging' Trying to connect over FTP to either of the web servers results in a 530. I've spent 2 hours scouring Google trying to find a solution, short of uninstalling the Advanced Logging Module. As far as I can tell, there is no way to turn off Advanced Logging on a site per site basis. Help would be appreciated.

• Adding new SPNs to existing service ids

  - by jmh

  We have a tomcat server using spring-security kerberos to authenticate users to the webpage against active directory. There are around 25 domain controllers. The site has two CNAME based DNS aliases. The site currently has one Service ID with SPNs registered for the DNS A record as well as each of the CNAMEs. While everything is working right now, I don't know how to reliably change this configuration without possible downtime. The reason is that clients cache kerberos tickets: http://www.juniper.net/techpubs/en_US/uac4.2/topics/concept/user-role-active-directory-about.html The 'kerbtray.exe' program is helpful for viewing and deleting Kerberos tickets on the endpoint. Old tickets must be purged from the endpoint if SPNs are updated or passwords are changed (assuming the endpoint still has a cached copy of the ticket from a prior SPNEGO request to the MAG Series device. During testing, you should purge tickets before each authentication request. Description of "klist" program used to inspect/delete cached tickets: http://technet.microsoft.com/en-us/library/hh134826.aspx So if each of the clients (users running windows) who connect to my web server have kerberos tickets that become invalid as soon as I update the SPNs or passwords, how do I ensure changes are seamless? Are there any operations that can be done safely? I can't just ask all of the users to install klist and delete their old tickets.

• Setting "Run WWW service in IIS 5.0 isolation mode" does not persist in IIS 6

  - by Saul Dolgin

  Our IIS server was recently patched with the latest Microsoft Security Updates and since then, I am unable to enable the "Run WWW service in IIS 5.0 isolation mode" setting. This setting was enabled prior to patching and somehow changed during the updates. I have tried both using the IIS Manager console and the adsutil.vbs approach to change it. Either way, after resetting IIS for the change to take effect, when I go to verify that the isolation mode setting is enabled (true) I find that is reverts back to being disabled (false). Now... The patches have already been rolled back, however the setting still does not persist when I enable it. While I am trying to research the patches that were applied to see if there is a known issue (or perhaps a change in this setting's behavior) I was hoping someone else might have come across the same problem. Any help towards a workaround would be greatly appreciated! >cscript adsutil.vbs set W3SVC/IIs5IsolationModeEnabled TRUE IIs5IsolationModeEnabled : (BOOLEAN) True >iisreset Attempting stop... Internet services successfully stopped Attempting start... Internet services successfully restarted >cscript adsutil.vbs get W3SVC/IIs5IsolationModeEnabled IIs5IsolationModeEnabled : (BOOLEAN) False

• DriveImage XML fails with a Windows Volume Shadow Service Error

  - by ssvarc

  I'm trying to image a SATA laptop hard drive, using DriveImageXML, that is attached to my computer via a USB adapter. I'm running Win7 Ultimate 64 bit. DriveXML is returning: Could not initialize Windows Volume Shadow Service (VSS). ERROR C:\Program Files (x86)\Runtime Software\Drivelmage XML\vss64.exe failed to start. ERROR TIMEOUT Make sure VSSVC.EXE is running in your task manager. Click Help for more information. VSSVC.EXE is running in Task Manager, as is VSS64.exe. Looking at the FAQ on the Runtime webpage this turned up: Please verify in Settings-Control Panel-Administrative Tools-Services that the following services are enabled: MS Software Shadow Copy Provider Volume Shadow Copy Also make sure you are able to stop and start these services. Possible reasons for VSS failures: For VSS to work, at least one volume in your computer must be NTFS. If you use only FAT drives, VSS will not function. The required NTFS volume does not need to be identical with the volume you want to image. You should make sure that VSSVC.EXE is running in your task manager. If the problems persist, registering "oleaut.dll" and "oleaut32.dll" using "regsvr32" might help. Both of those services are running and can be started and stopped without issue. Using "regsvr32" to register ""oleaut32.dll" returns successful, but "oleaut.dll" returns: The module "oleaut.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found. Some other information that might be relevant. Browsing to the drive is successful, but accessing certain folders returns an "access" error. Windows runs a permissions adder that adds the current user profile to the NFTS permissions. Could this be the cause of the issue? DriveImage XML is running as Administrator. Thoughts?

• systemd: enabling cherokee service as a `unit file`

  - by Calvin Cheng

  So I am learning how to use systemd to initialize my services automatically on server reboot. So of course, I first make sure I have systemd and some optional systemd related packages installed. pacman -S systemd initscripts-systemd Installation seems to go well and checking, I can see that systemd and its dependency libsystemd are installed. And the optional package initscripts-systemd is also installed:- [root@li280-195 ~]# pacman -Ss systemd extra/libsystemd 44-5 [installed] systemd client libraries extra/systemd 44-5 [installed] system and service manager extra/systemd-sysvcompat 2-2 sysvinit compat symlinks for systemd community/initscripts-systemd 20120412-1 [installed] Arch specific systemd initialization/bootup scripts for systemd community/systemd-arch-units 20120412-2 Arch specific Systemd unit files Next, I ensure that systemd is loaded up when my server reboots, via grub in grub's /boot/grub/menu.lst file like this:- kernel /boot/vmlinuz root=/dev/xvda ro init=/bin/systemd Rebooting my server to check, all loads up well and I can check that systemd is operational via:- systemctl list-unit-files However, I don't see my cherokee initialization script (which is simply created at /etc/rc.d/cherokee when I installed cherokee earlier via pacman -S cherokee) being listed as one of my unit files. So the question is, how do I do that? How do I put my cherokee initialization script under systemd's control?

• Autodiscover service seems to reply with User Principal Name instead of email address

  - by Jeff McJunkin

  After this latest round of Windows updates (on 1/11/11, in fact) my Exchange 2007 server of course rebooted. This may have had the side effect of making any changes I'd inadvertently made take effect. Since then, the Autodiscover service in Exchange 2007 from Outlook 2007 seems to reply with the User Principal Name ([email protected] instead of [email protected]). I'm specifically seeing this from within the "Test Email AutoConfiguration" tool in Outlook (the UPN appears in the first text box labeled "E-mail") and when creating a new profile in Outlook. If I disregard the UPN and instead fill in my email address, Autodiscover works as expected and I can connect without issue. I've confirmed using ADSI Edit that the SMTP email address is properly set for my users. I even went a bit crazy and set the UPN to the email address using ADSI Edit. I've re-installed the Client Access role on the server in question. Exchange server is Server 2008, 64-bit of course. Clients are mostly XP 32-bit, though the issue happens from a Windows 7 machine as well.

• Anti Virus Service does not run - Windows XP SP3 32bit Home

  - by Stefan Fassel

  I have a somewhat strange problem here. I am trying to run Anti Virus Software on my Windows XP Home 32bit System. After a serious crash I had to fall back to an outdated copy of my initial installation and had Windows install 5 years of updates. So far so good. After Intalling a new Anti Virus Software (Bitdefender 2012) everything seemed to be fine, initial scanning went fine and configuration was working. But after restarting the System the Virus Scanner was unable to start up again. Even the Configuration console of the AV Software did not start. I tried scanning the System for malware, but nothing was found. Then I tried a different AV Software (MS Security Essentials), but in the end it did fail to start too. I have tried to start the Service manually, but I seem to be missing the privilege to do so. I am logged in as a Non-"Administrator" User with Admin privileges (Not much choices there on a XP Home System). I cannot switch to Administrator account outside the protected mode. When running Windows in protected mode I am unable to start the AV Software because it does not run in protected mode. I am a bit at loss now...

• If I implement a web-service, how do I respond to POST requests with JSON?

  - by Vova Stajilov

  I have to make a rather complex system for my diploma work. Logically it will consist of the following components: Database Web-service Management with web interface Client iOS application that will consume web-service I decided to implement all the first three components under .NET. Firstly I will create a database depending on the information load - this is clear. But then I need a web-service that will return data in JSON format for iOS clients to consume - that's obvious and not that hard to implement. For this I will use WCF technology. Now I have a question, if I implement the web-service, how will I be able to respond to POST requests with JSON? It probably involves WCF JSON or something related? But I also need some web pages as admin part, so will this web-application be able to consume my centralized web-services as well or I should develop it separately? I just want my web service to act like a set of controllers. There is a related question here but this doesn't quite reflect my question.

• mshtml.dll latest version for Internet Explorer 8, Windows XP Service Pack 3

  - by AllSolutions

  Many applications in my system (Internet Explorer 8, Yahoo Messenger, Skype 10) are crashing and error details shows module name mshtml.dll. I checked the version of mshtml.dll in system32 folder. It is 8.0.6001.19170. My Internet Explorer version is 8.0.6001.18702. I am not concerned about crash of IE, because I generally use Firefox, but how do I solve the crashes in other applications, which are due to mshtml.dll? I have moved to Windows XP Service Pack 3 (32 bit). I have tried to update Internet Explorer 8 (from Tools-Windows Update), but again it crashes. I can not migrate to IE 9, as it requires Vista or Windows 7. I have applied Cumulative Security update for IE8, which has this file name: IE8-WindowsXP-KB2618444-x86-ENU.exe I could not get much info from Microsoft sites or Google. I do not want to use Automatic Updates feature of Windows. Can somebody give the download links for mshtml.dll and any associated files, which I can replace in system32 folder? Thanks.

• Firefox proxy authentication with Kerberos: one service ticket per connection (Linux)

  - by Dari

  I am trying to enable proxy authentication via Kerberos for Firefox. The setup is: Active Directory domain (for LDAP and Kerberos; this works and I can log in the computer and get Kerberos tickets without problems) Microsoft Windows witness machine (on which Firefox runs fine with no ticket problem) CentOS 6.3 system with Firefox (the tests were performed with both the 10.0.1 ESR found in the CentOS package repositories and the 15.0.1 downloaded from Mozilla's website) BlueCoat proxy with Kerberos authentication enabled For the moment, Firefox requests an element of a website, gets an HTTP error code of "407 Proxy Authentication Required" from the proxy, gets a ticket granting service (TGS) from the domain for the proxy and performs the request again while passing the ticket. The transaction runs fine. However, when more elements are requested (in parallel), Firefox requests one more ticket per proxy connection. And this takes many DNS queries, Kerberos interactions with domain controllers and costs a lot of time (for example, the home page of Adobe takes several minutes to load and at the end, I have about 30 valid Kerberos tickets). I am stuck on this since a while, and help would be greatly appreciated. Minor information: the CentOS operating system is virtualized with VMware Player 3.1.3, but I do not think this would be a game changer.

• Service Layer - how broad should it be, and should it be used also on the local application?

  - by BornToCode

  Background: I need to build a main application with some operations (CRUD and more) (-in winforms), I need to make another application which will re-use some of the functions of the main application (-in webforms). I understood that using service layer is the best approach here. If I understood correctly the service should be calling the function on the BL layer (correct me if I'm wrong) The dilemma: In my main winform UI - should I call the functions from the BL, or from the service? (please explain why) Should I create a service for every single function on the BL even if I need some of the functions only in one UI? for example - should I create services for all the CRUD operations, even though I need to re-use only update operation in the webform?

• Server Recovery from Denial of Service

  - by JMC

  I'm looking at a server that might be misconfigured to handle Denial of Service. The database was knocked offline after the attack, and was unable to restart itself after it failed to restart when the attack subsided. Details of the Attack: The Attacker either intentionally or unintentionally sent 1000's of search queries using the applications search query url within a couple of seconds. It looks like the server was overwhelmed and it caused the database to log this message: Server Specs: 1.5GB of dedicated memory Are there any obvious mis-configurations here that I'm missing? **mysql.log** 121118 20:28:54 mysqld_safe Number of processes running now: 0 121118 20:28:54 mysqld_safe mysqld restarted 121118 20:28:55 [Warning] option 'slow_query_log': boolean value '/var/log/mysqld.slow.log' wasn't recognized.

• Cocos2d: Adding a CCSequence to a CCArray

  I have a problem with an action performed by a sprite. I have one CCSequence in a CCArray and I have an scheduled method (is called every 5 seconds) that make the sprite run the action.

• Using .add() on the same widget more than once

  - by Dillon Gilmore

  I asked this question on Reddit and was directed here. http://www.reddit.com/r/Ubuntu/comments/vhadl/quickly_dynamic_ui/ Unfortunately I am having the same issue and the problems seems that you can only use .add() on a widget once. So here is my code, self.ui.labels = [] for titles in entries: label = Gtk.Label() self.ui.labels.append(label) self.ui.viewport1.add(self.ui.labels[-1]) self.ui.paned1.show_all() Now, for fun I decided "What would happen if I just manually did..." self.ui.viewport1.add(Gtk.Label()) self.ui.viewport1.add(Gtk.Button()) self.ui.viewport1.add(Gtk.Entry()) For my first code snippet I get this error, Gtk-CRITICAL **: gtk_viewport_add: assertion gtk_bin_get_child (bin) == NULL' failed The error happens an unknown amount of times because the list entries can vary in length, but for my second code snippet it happens exactly twice. This means that when I viewport1.add() it works the first time, but all adds after that receive the error above. So my question, is there a way in python to use .add() on the same widget more than once?

• Intermittent FTP login issues (Microsoft IIS FTP Service)

  - by JaggenSWE

  I've got a somewhat weird problem which I'm not sure how to troubleshoot. We have a FTP running on a Windows Server 2003 machine using the IIS FTP Service, this is for our clients and is configured with IP-restrictions. However, now ONE of the clients starts complaining that they can't log in to the server from time to time. This is just ONE of 10+ clients that have this issue, which makes me think it's a problem on their side. Just to be on the safe side I had a peek into the FTP logs and found something strange. Whenever succeed in loggin in this is what I can find in the logs: nnn.nnn.nnn.70, userxxx, 2012-06-11, 09:22:32, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 331, 0, [191747]USER, userxxx, -, nnn.nnn.nnn.70, userxxx, 2012-06-11, 09:22:32, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 230, 0, [191747]PASS, -, -, However, if the login fails I see the following events: nnn.nnn.nnn.70, userxxx, 2012-06-11, 09:16:33, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 331, 0, [191739]USER, userxxx, -, nnn.nnn.nnn.70, -, 2012-06-11, 09:16:33, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 530, 1326, [191739]PASS, -, -, When you look at the event where the clients sends the PASS in the successful login it seems to know that it is infact "userxxx" that is coupled to that PASS, but when it fails it seems to be lost since user in the PASS event is set to "-". Anyone have any ideas around this, any help would be appreciated. :) //JaggenSWE

• Crash due to removal of Elements like CCSprite from NSMutableArray

  So, here's how it goes. I am currently working on Cocos2d game, which consists of many Obstacles. One obstacle gets added on the screen at an interval of 10 seconds like this. ObstacleSprite* newObstacle = [ObstacleSprite spriteWithFile:@"Obstacle.png" rect:CGRectMake(0, 0, 20, 20)]; newObstacle.position = ccp(mainPlayer1.position.x,10); [self addChild:newObstacle]; [self.arrayForObstacles addObject:newObstacle]; Now, I insert these obstacles into the arrayForObstacles because I also want to keep checking whether the Obstacles and MainPlayer don't collide. I check it with the help of this function. - (void) checkCollisionWithObstacle { if(mainPlayer1.playerActive) { for(int i = 0; i < [self.arrayForObstacles count]; i++) { ObstacleSprite* newObstacle = [self.arrayForObstacles objectAtIndex:i]; if(newObstacle != nil) { if(CGRectIntersectsRect([mainPlayer1 boundingBox], [newObstacle boundingBox])) { mainPlayer1.livesLeft--; } } } } } THE ISSUE Problem is when I get to certain score, one of the Obstacles gets deleted. Removal of Obstacles works as in First In-First Out (FIFO) mode. So, to delete obstacles, I write the following method : - (void) keepUpdatingScore { //update new score mainPlayer1.score+=10; //remove obstacle when score increases by 5k if(mainPlayer1.score > 5000 && mainPlayer1.score > 0) { mainPlayer1.playerActive = NO; if([self.arrayForObstacles count] > 0) { CCLOG(@"count is %d",[self.arrayForObstacles count]); ObstacleSprite* newObstacle = [self.arrayForObstacles objectAtIndex:0]; [self.arrayForObstacles removeObjectAtIndex:0]; [self removeChild:newObstacle cleanup:YES]; CCLOG(@"count is %d",[self.arrayForObstacles count]); } } else { } } It crashes when score crosses 5000 mark! UPDATE Crash happens when it again goes to the method checkCollisionWithObstacle. This is the THREAD Look. THis is the line Which crashes.

• As a self-taught programmer, how do I get the academic foundation without attending school again?

  - by hal10001

  I've made a pretty good living as a self-taught programmer, but when I find that I discuss some low-level fundamental topics with my peers who have a CS degree, holes appear in my knowledge. I'm a big picture (architecture) guy, so for a long time this hasn't bothered me, but lately I've wondered if there is an approach I can take that will help me learn these fundamentals without going back to school? Are there books, websites or videos that you can recommend that would give me a ground-up perspective as opposed to a learn it as you need it mentality?

• Crash when using Cocos2d

  - by ipodfreak0313

  Sorry about the poor question title, it's just that this seems to big for a title. So here's the dirt: I am making a game (obviously) and I want the enemies to shoot (not necessarily at the player). I want the shoot method to be in the Enemies file, so as not to clutter up my HelloWorldLayer.m file even more. Here's what I'm using right now: HelloWorldLayer.m -(void)addEnemy:(BigAndStrongEnemy *)enemy { enemy = nil; if((arc4random() % 4) == 3) { enemy = [BigAndStrongEnemy enemy]; } else { enemy = [SmallAndFastEnemy enemy]; } if(buffDude.position.y > character.position.y || buffDude.position.y < (character.position.y + 10)) { } int rand = arc4random() % 320; if((arc4random() % 2 == 1)) { [enemy setPosition:ccp(0,rand)]; }else{ [enemy setPosition:ccp(480,rand)]; } [self animateEnemy:enemy]; [self addChild:enemy]; } -(void)animateEnemy:(BigAndStrongEnemy *)enemy2 { float randX = arc4random() % 480; float randY = arc4random() % 320; int rand = arc4random() % 320; CGPoint moveToPoint = CGPointMake(randX, (randY - rand)); [enemies addObject:enemy2]; action = [CCSequence actions: [CCMoveBy actionWithDuration:1 position:ccpMult(ccpNormalize(ccpSub(moveToPoint, enemy2.position)), 75)], [CCMoveBy actionWithDuration:3 position:ccp(buffDude.position.x,buffDude.position.y)], nil]; CCCallFuncO *a = [CCCallFuncO actionWithTarget:self selector:(@selector(shoot:)) object:enemy2]; CCSequence *s = [CCSequence actions:action,a, nil]; CCRepeatForever *repeat = [CCRepeatForever actionWithAction:s]; [enemy2 runAction:repeat]; } And here's the Shoot info from the Enemies class: Enemies.m: -(void)shoot:(id)sender { self = (BigAndStrongEnemy *)sender; [self shoot]; } -(void)spriteMoveFinished:(id)sender { CCSprite *b = (CCSprite *)sender; [self removeChild:b cleanup:YES]; } -(void)shoot { self = [CCSprite spriteWithFile:@"bigAndStrongEnemy.gif"]; CCSprite *b = [CCSprite spriteWithFile:@"bullet.gif"]; b.position = ccp(self.position.x,self.position.y); b.tag = 2; [self addChild:b]; [bullets addObject:b]; CGSize winSize = [[CCDirector sharedDirector] winSize]; CGPoint point = CGPointMake((winSize.width - (winSize.width - self.position.x)),0); [b runAction:[CCSequence actions: [CCMoveBy actionWithDuration:0.5 position:point], [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)], nil]]; } Every time the 3 seconds goes by, the app crashes, and goes to the breakpoint in the CCCallFuncO file. I haven't touched it, is the thing. I am completely confused. Any help is greatly appreciated.

• PST backup with Volume Shadow Copy Service

  - by NoMadMan

  I was asked to implement the task of backing up 35 PST files ranging from 800Mb to 2000Mb. Windows XP and Windows 2000 workstations are assigned to the users and we have a Windows 2000 domain controller we use to back up files on 3x 500Gb external hard drives. I found several methods from applications to scripts. Local or remote applications would be my last resort. I came across this script based on Volume Shadow Copy Service. CopyWithVss I wanted to know if there would be a problem if the path had spaces. Would mounting the destination path of each PST folder with a drive letter be more practical? My concern with mounting option is that i would eventually run out of letters since I have 35 and possibly more workstations to back up. Lastly, can someone give me an example of CopyWithVss if it were run on a production network? The script is a bit cryptic even after reading several times. Where in the script do I enter the source and the destination? I'm a Mac user so please excuse my ignorance with Windows platform.

• Running batch file through a service.

  - by wallz

  I'm trying to schedule a batch file to run through a third party application, however the output file doesn't get created in the directory. If I run the .BAT file from the command line, it works and the file gets created. Also using the Windows Schedule will also succeed. Basically, the 3rd party software will schedule the .BAT file and it shows success within the 3rd party user interface. The difference between running from the command prompt and the software, is that the software will use its Windows service to launch the batch. The 3rd party software will show success since it was able to successfully call the .BAT file to run, however it has no control of the other EXE's that's being called within the script. I'm able to run a simple .BAT file in the 3rd party software, for example a copy command. The .BAT I'm having problems with calls a compiled EXE which launches Excel to create a file to a location. The .bat file calls something.exe, which then calls Excel.exe: C:\something.exe -o D:\filename.xlsm C:\filename.xlsm refresh_pivot Do you think it's a permissions issue? I used Process Monitor to verify any Access Denied errors but everything seems to be working according to the trace. It worked on a non-64-bit OS, I'm currently using Win2008 64-bit.

• Dual DC Time Service

  - by poconnor

  I believe I'm having an issue with my Domain Controllers and Time Server. On my back up DC, I keep seeing a warning stating "The time service has stopped advertising as a time source because the local clock is not synchronized." Does this mean that my backup DC believes it's a Time Server? My PDC should be the time server and I have gone through setting up the PDC as the time server. I was not around for the original setup of the time server with the old PDC and Backup DC. But I believe the old PDC was the time server so I setup the new PDC as the new time server, when I decommissioned the old PDC. Is it possible that the Backup DC was setup as the time server and it still thinks it's suppose to be giving out time to everyone? Registry for PDC has NTP Registry for Backup has NT5D5 Results of w32tm /monitor Getting AD DC list for default domain... Analyzing:delayoffset from DC1.local..com Stratum: 4 delayoffset from DC1.local..com Stratum: 3 Warning: Reverse name resolution is best effort. It may not be correct since RefID field in time packets differs across NTP implementations and may not be using IP addresses.
