• How do I fix error 1303 during TI Connect install?

  - by smoth190

  I recently purchased a TI-84 Plus graphing calculator, and I'm trying install the TI Connect software in order to connect the calculator to my computer via the USB cable. Unfortunately, I'm getting this error while trying to install the program: Error 1303. The installation has insufficient privileges to access this directory: E:\Data\Timothy\Documents\MyTIData. The installation cannot continue. Log on as administrator or contact your system administrator. However, my account is the only account on my PC, and it has administrative privileges. I've also tried running the installer with Run as Administrator, but with no luck. If I create the folder MyTIData manually, I receive this error: Error 1317. An error occurred while attempting to create the directory: E:\Data\Timothy\Documents\MyTIData I've reapplied the security settings to the E:\Data folder (and all its sub-directories) to Full for my account. I've also gone into Computer Management, and given SYSTEM full privileges for the entire disk. I've also logged out, logged back in, restarted, etc. but still, no luck. Now, I should mention that my Documents folder is not at the default location. I changed it due to my C: disk being a 90GB SSD, so I moved all my personal data onto the extra storage disk (which is ~1TB). I don't know if that is causing the issue, but it can't hurt throwing it out there. So why can't I install this program? Google'ing the problem brings up this error for various other installers (such as Visual Studio and Microsoft Office), but nothing for TI Connect. All the solutions are the same: Give the folder Full privileges...but I've already done this! I've also tried running the installer with and without the calculator plugged in, but it didn't change anything. In the prompt that contains the error, repeatedly clicking Retry or waiting a few moments before clicking Retry also produces no result.

• Looking for a small, portable, port-mirroring ethernet switch.

  - by user37244

  I recently had a mac go haywire, taking half a minute or more to get www.google.com loaded. Getting its owner to give up the machine for repair was like pulling teeth - they were insisting that it must be something to do with the network, since so much had changed with the local configuration at about the same time their box went haywire. I eventually set up a port mirror to a box that I could remote to so I could show that the mac was only irregularly getting packets onto the network. Demonstrating this faced an additional challenge: the latency of the remote desktop software I was using meant that I had to point to timestamps instead of just the moment the packet flashed up on the screen as my evidence. This particular user was the reason this was so challenging this time around, but I would like to have a box that I can cart from desk to desk to use wireshark on my laptop at any station where I need it. 3com, cisco, netgear, etc. (ad nauseum), all make switches that can be configured for port mirroring, but in my case, the smaller, the better. For the sake of my sanity, I'll probably end up running it off a battery anyway. If my laptop had two ethernet ports, this would be easy. So, whaddya recommand for a device that requires 0 configuration at each powerup (though I'm fine with poking at it for a while to set it up initially.) Small, light, and cheap enough to get it past purchasing? Thanks,

• Configure Apache + Passenger to serve static files from different directory

  - by Rory Fitzpatrick

  I'm trying to setup Apache and Passenger to serve a Rails app. However, I also need it to serve static files from a directory other than /public and give precedence to these static files over anything in the Rails app. The Rails app is in /home/user/apps/testapp and the static files in /home/user/public_html. For various reasons the static files cannot simply be moved to the Rails public folder. Also note that the root http://domain.com/ should be served by the index.html file in the public_html folder. Here is the config I'm using: <VirtualHost *:80> ServerName domain.com DocumentRoot /home/user/apps/testapp/public RewriteEngine On RewriteCond /home/user/public_html/%{REQUEST_FILENAME} -f RewriteCond /home/user/public_html/%{REQUEST_FILENAME} -d RewriteRule ^/(.*)$ /home/user/public_html/$1 [L] </VirtualHost> This serves the Rails application fine but gives 404 for any static content from public_html. I have also tried a configuration that uses DocumentRoot /home/user/public_html but this doesn't serve the Rails app at all, presumably because Passenger doesn't know to process the request. Interestingly, if I change the conditions to !-f and !-d and the rewrite rule to redirecto to another domain, it works as expected (e.g. http://domain.com/doesnt_exist gets redirected to http://otherdomain.com/doesnt_exist) How can I configure Apache to serve static files like this, but allow all other requests to continue to Passenger?

• Good process/software for organizing photos past/present

  - by Matthew

  So I have tons of photos taken all the time. I have a lot from years past that I never went through (meaning deleting duplicates, etc). I've got a new pc with windows 7, and I'm wondering what a good process is to organize those photos. They're in folders that have really no meaning (it used to be people would put them in a folder wherever, even the desktop or somewhere else, not just the My Pictures folder). I'm going to keep all pictures in the "My Pictures" folder from now on. I've used Picasa from g=Google, and it works great. Is this the recommended free software for this? What process do I use to move the old pictures over in to new "organized" folders? Lately in Picasa when I import off my camera card, I would just select something that names the folder after the date it was taken. Is this advised? Just give me ideas on how to stay organized with photos. Should I tag them also? Should I rename the file names? Keep in mind I have over 16,000 photos I'll have to go through, so it can't be anything to thorough.

• Process PHP files from a network share in a vmware virtual machine

  - by nhinkle

  As a testing environment, I have set up a vmware virtual machine running Windows Server 2008 R2. I have Apache and PHP installed (as part of the xampp package). I am doing the development outside of the VM, and so want Apache to serve PHP files from a VM shared folder (which appears as a network share in the VM). I have done this by creating an NTFS symbolic link in Apache's htdocs directory. I can access this directory from the browser, and plain-text files are readable. However, PHP fails to process files, instead returning the following error: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'C:/xampplite/htdocs/path/to/file.php' (include_path='.;C:\xampplite\php\PEAR') in Unknown on line 0 It appears to be a permissions issue — PHP doesn't seem to be allowed to read the file to process it. However, Apache has no problem opening files in the directory. I cannot figure out how to give PHP the necessary permissions to process the file. Does anybody know of a way to make this work, or else another solution for getting the files into the VM automatically while I develop on the host machine?

• How to configure Windows user accounts for ODBC network with NT authentication?

  - by Ian Mackinnon

  I'm trying to create a connection to an SQL Server database from the ODBC Data Source Administrator using "Windows NT authentication using the network login ID". Both server and client are running Windows XP. It appears that any account with administrator privileges can add the data source on the server*, though connection attempts from the client result in error messages that suggest it is trying to authenticate using a guest account. I found a Microsoft support page that says: For SQL Server...: connect using the impersonated user account. But it doesn't offer advice about how to do that. How do I impersonate a user account on the server? or (since it sounds like that would lead to an unfortuante squashing of privileges and loss of accountability): How do I give an account on the client privileges on the server database and then ensure the client attempts authentication with the privileged account and not with a guest account? I'm aware that I'm providing rather sparse information. This is because I'm in unfamiliar territory and don't know what's pertinent. I'll attempt to add any requested information as quickly as possible. *I'm planning on tightening privileges straight after I get it working as it stands.

• Does my Oracle DBA need root access?

  - by Dr I

  I'm currently discussing with my Oracle DBA Collegue that request a root access on our production servers. I'm not so hot to let him use the root access on our production servers. He is arguing that he need it to perform some operations like restarting the server and some other obscure arguments. The point is that I'm not agree with him because I've set him a Oracle user/group and a dba group where Oracle user belong. Everything is running smoothy and without any root permissions for now. I also think that all administrative tasks like scheduled server restart and so one need to be operated by the proper administrator (The Systems administrator on our case) to avoid any kind of issues related to a misunderstanding of the infrastructure interactions. So, I need the help of both, sysadmins and Oracle DBAs to lead me on the correct direction. If my collegue really need this rights I'll give him, but I'm just basically quite affraid of that because of security and integrity concerns. I know that my collegue is really good as a Oracle DBA and he know is work very well, but I also know that I've very few cases where a software and its admin really need root access. Once again, I'm not looking for pros/cons but rather an advice on the way that I should take to deal with this situation.

• How do you notice that the batteries of you wireless mouse are dying out?

  - by hkBattousai

  I have a Logitech M705 wireless mouse. I'm first time using a wireless mouse, so I don't have much experience with the hardware features and behavior. It is rated that it runs for 3 years with the same batteries. I think this "3 year" rating is calculated for a very low usage and activity; like 2 hours a day. I'm using it for about 12 hours a day, so I expect it to run out of batteries in a much shorter time in my case. I have been using it for about half a year. Recently (for the last two weeks), it started to make some peculiar behavior when clicking and drafging objects. - When I click something, it sometimes double click it. - When I drag something from one place to another (or selecting some text), it sometimes drops the object in the halfway (when selecting text, the text which had selected up to that time becomes unselected and it starts to select the rest of the text from that moment), but it goes on being in the "left-button-pressed" state. It is like, the pressed button switches to "unpressed" state for a moment, then returns back to the "pressed" state. When one of these faults occur, it occurs several times sequentially. There is no problem in pointer movement, scrolling or right-clicking. Since the batteries last for a very long time for this device, I don't expect it to stop working in an instance. I expect it to give these kind of syndromes of a time period. My question is; Is this how batteries run out for a wireless mouse? Or, is this another kind of hardware/software problem?

• Does a VPN requirement kill the concept of having a Web Application in the Cloud?

  - by Christian

  Recently I posted a question in SO, but so far I got no answers. I wonder if I'm asking the wrong question. This is the problem: We need to design an application which offers a public http web service, but at the same time it must consume some services through a VPN connection from other existing company. There is no other alternative but to use a VPN connection to access those services. We want to host our application in some cloud infrastructure like Heroku or Amazon EC2. But there is no direct way to access the VPN services of the other company from there. The solution I'm thinking, but I don't like is to have a different server to expose the services from that VPN. But this will require the setup of another server which I prefer to avoid. In the case this is the solution, can I use an Amazon EC2 instance to connect to a VPN? This is what I was thinking, is it correct? I don't have experience using VPNs, tunnels or those kind of networking stuff. I will really appreciate if you can propose me an alternative solution, or just give me a comment.

• Java website on Tomcat PHP website on Apache - how to get PHP web pages into Java web pages?

  - by Venkat

  We have a Java web application deployed on Tomcat. We also setup Apache and mod_proxy_ajp to route web requests (port 80/443) to Tomcat. We would like to deploy a PHP application on the same Apache server - probably under a subdirectory (/var/www/ourapp). Now we would like to access & display web pages from PHP application within web pages generated by Java application. Planning to implement Single Sign-on as well. Example: Web page from java has (JQuery Tabs) and we like to display the PHP web page within a tab while all other HTML comes from java application. Can you please give a overall picture of how to proceed about this? Mainly 1. how we should install/setup our PHP application on same Apache server which is used to route web requests to Tomcat? i.e. either setup sub domain or install in sub directory 2. How to bring PHP pages into present web pages (generated by java). Can we use AJAX requests or should go for Java PHP Bridge/ Querces such applications? Thank you for your time in advance. Regards.

• Printer spooler service stop running when sent print job

  - by Hanan N.

  Every time i am sending a print job to the printer, i am don't get any response from the printer, and at the printer job list at the status of the job, i see that there was an Error, but it don't give me any clue on what could be the problem. After some investigation i found that every time that i send the print job to the printer the printer spooler service stops to run, then after a second or two it start again (i think that this behavior is related to the printer spooler settings to rerun it self after it stops). Things that i have tried so far: Remove and Install again the Driver. After removing the driver, i have removed the unnecessary registry keys according to this article from Microsoft, these are: Rename all files and folders in: c:\windows\system32\spool\drivers\w32x86 Remove anything but Drivers Print and Processors: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environment\Windows NT x86 Remove anything in here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors but: BJ Language Monitor Local Port Microsoft Document Imaging Writer Monitor Microsoft Shared Fax Monitor Standard TCP/IP Port USB Monitor WSD Port Disconnect and Reconnect the Printer. Clean the computer from Viruses & Spywares. Currently i am stuck, i have no more things to try, if anybody know about any kind of solution please let me know about it. Since i am want to keep this post as general problem that relate to the printer spooler, and not just my particular problem, i didn't included inside the windows version & the printer model, they are (although i think that it isn't relate just for that particular model): Windows 7 32bit, HP Officejet 4500 G510g-m (connect to the computer via USB). Thanks.

• File Open/Save Dialog always 'Not Responding'

  - by Amanda

  I am aware that this question has been asked once, however the solution for them didn't work with me. Whenever I go to open/save a file in any program, the dialog does not come up, and the application goes to 'Not Responding'. This goes on for about a few minutes, and then stops, but still does not open the dialog. There have been a few occasions where the dialog has suddenly worked for a while, but then the problem comes back. I have tried many solutions given around the internet, I have cleaned it with CCleaner, disk defragged it, sorted the index. Nothing works. Is there anybody who has any idea what the problem is? This is Windows Vista. I'm not quite sure what kind of information you guys would need about my laptop, but I'll give you it if you need it. :) Solutions I have Tried: I have tried deleting the 'Shellicon' folder in the registry, which wasn't even in there. I have looked for mapped network drives lingering around, and I haven't come across any. I have tried rebuilding teh Widnows Search Indexes...no difference.

• Servers / ram for social network- how many?

  - by Marty

  I am launching my social network soon an looking into hosting. The question i am lost is: Do i need separate servers for web vs database vs image handling since there is photo sharing? Or does 1 server handle it all? Also is more ram better? If i get 50GB ram is that better than having 8 gb ram? EDIT: It is PHP codeignitor and MySQL for now. (switch to NoSQL DB later if demand calls fr it.) I will be using memcache also. Concept wise it is similar to yelp, so geographic based with lots of user content and image sharing + live feeds an privacy levels. User plan is open question. Without testing the demand for this i cant give a number. But the concept is unique, no one out there with the set of features i am releasing so it could grow. Ideally I want to plan for handling about 1-2 million views / month from launch. If it goes more than that then I will upgrade.

• Family server setup [closed]

  - by Manny

  Hi all, I really hope some of you can give me some direction. I have setup a linux server at home and through samba I can access files from different computers in my home. I would like to use this server as a file-server for my family (brothers, sisters and parents who all live in their own homes). I really like the way it is set up right now with user and permission controls, but I've read that it is bad idea to open up the samba port to the world. The requirements are simple: 1) it should be easy to access, by using standard web browsers or mounting the drive (shouldn't have to use any VPN setup or use putty etc) 2) should be somewhat secure. We just want to share family pictures instead of putting them on facebook or picasa or other web server, nothing top secret. Here is what I've looked into: 1)Webdav. It seems decent but seems like it windows7 doesn't like it very much, even with digest mode authentication. User controls and permissions are not as flexible as samba (or at least to my knowledge). I really like the user and group permissions in samba, but if I could live with webdav if it worked seamlessly with windows, it should just work shouldn't it? 2) I read somewhere to stay away from ftp as it is outdated and that there are newer and better internet file-server setups? Was that a reference to webdav? I am so confused, please help... Manny

• tmpreaper, --protect and a non-root user

  - by nsg

  Hi, I'm a little confused. I have a download directory that I want to remove all files older then 30 days with tmpreaper. Just one problem, the directory in question is a separate partition with a lost+found directory, of course I need to keep it so I added --protect 'lost+found', the problem is that tmpreaper outputs: error: chdir() to directory 'lost+found' (inode 11) failed: Permission denied (PID 30604) Back from recursing down `lost+found'. Entry matching `--protect' pattern skipped. `lost+found' I have tried with other pattern like lost* and so on... I'm running tmpreaper as a non-root user because there is no reason for superuser privileges because I own all files (except lost+found). Are I'm forced to run tmpreaper as root? Or are my shell-skills not as good as I thought? I guess the problem is: tmpreaper will chdir(2) into each of the directories you've specified for cleanup, and check for files matching the <shell_pattern> there. It then builds a list of them, and uses that to protect them from removal. Any thought and/or advice? Edit: The command I'm trying to run is something like $ /usr/sbin/tmpreaper -t --protect 'lost+found' 30d /mydir 1> /dev/null error: chdir() to directory `lost+found' (inode 11) failed: Permission denied Edit 2: I read the source code for tmpreaper-1.6.13 and found this if (safe_chdir (dirname)) exit(1); and if (chdir (dirname)) { message (LOG_ERROR, "chdir() to directory `%s' (inode %lu) failed: %s\n", dirname, (u_long) sb1.st_ino, strerror (errno)); return 1; } So it seems tmpreaper needs to be able to chdir in to all directories, ignored or not. I see two options left Run tmpreaper as root Move the download directory Find a alternative tool (tmpwatch?) I will give it some more research before i make a choice.

• Apache2: Limit simultaneous requests & throttle bandwidth per IP/client?

  - by xentek

  I want to limit simultaneous requests & throttle bandwidth per IP/Client on a single apache vhost. In other words, I want to ensure that this site, which hosts large media files, doesn't get hammered by someone trying to download everything all at once (just happened the other night). I'd like to limit the outgoing transfer speed overall for this site, as well as limit the number of connections a single IP can make to the server to a sane default (i.e. within normal browser limits for multiple requests so page loads aren't effected too much). Bonus points if I can actually scope it to file types (i.e. leave web files alone, but apply these rules to just the media files). We're running Ubuntu 9.04 on all the servers, and have two apache/php servers being load balanced via Round Robin by a squid proxy server. MySQL is running on its own box as well. We've got plenty of bandwidth to give them, so I don't really want overall caps, but just want to throttle the amount of memory/CPU it takes to serve this site. There other sites on these servers that we don't want to apply these rules too, just want to keep this one from hogging all the resources. Let me know if you need more info! Thanks in advance for your suggestions!

• How to set up daisy-chained routers for separate sub-nets?

  - by joe

  This question seems to be similar to others, but I'll take a shot anyway. A client recently switched ISPs from TDS to Comcast Business Class. Before the switch, they had 5 static IP addresses assigned. Now they'll have a single IP address that will change whenever Comcast decides to do so. The issue is that this internet connection will be shared among two companies, both having (and wanting to keep) their own private subnets. Because TDS was supplying multiple IP addresses to the one location, this allowed me to put each router on the switch. Now, with Comcast, they only get one IP address, meaning there has to be a main router before the subnet routers. Luckily, the cable modem has a built-in router, which I would like to connect to each company's router, and still have DHCP enabled on all accounts. Question: What do I need to do to the subnet routers to keep them separate from each other, but still allow internet access from the main router. I would love to say "I tried this", and give you links, but everything I find on the internet only mentions daisy-chaining routers with DCHP disabled.

• I can't get my PC to start up by a normal way.

  - by ssice

  I couldn't write a more accurate title. I am just unable to start the computer by pressing the Power On button. I checked the Power Supply and it seems to give good voltage values in every pin. And this is not a BIOS malfunction because of bad overclocking or anything that may come to your mind. And I will tell you why. It happens that EPS (or any ATX-based) power supply has the ability to be powered-on by the Motherboard by jumping the 13th pin of the 24-pin-ATX-connector to COM/GND. I did it, after pushing the power on button (without any visual response) and, pwhaa! The machine turned on. I was able to read (and even write, if I wanted) BIOS values and then start any OS installed. Machine starts, so it's not any kind of misconfiguration. It seems some hardware related. I am able to power the machine on only if I already pushed the power on button. Though pushing it without jumping the 13th pin to ground for a second does not power the machine. Of course, jumping the pin without pushing the power on button does not tell the motherboard anything, so the computer would not start up either. It's as if the logic that connects the power button with the 13th pin derivation to GND was unable to be activated. What can be the issue? How can I solve it? My configuration is as follows: CPU: AMD Phenom 9850 X4 Black Edition MB: ASUS Formula II AM2 RAM: 2x2GB Corsair Dominator 5-5-5-15 2T @ 1066MHz DDR2 Tested also with only 1 module GPU: 2x XFX nVIDIA GeForce 9600 GT XxX Alpha Dog Edition @ Core: 540Mhz [SLi] Power Supply: Xilence 700W (ATX 12V 2.3 / EPS 12V 2.92 compatible) PS: I know the machine is like 2 years old. I hardly use it now, but my parents do.

• linux routing issue

  - by Duc To

  Hi! I have 2 linksys routers which has linux running on it and using tomato firmware.. both has internet lines plugged on but only 1 acts as DHCP server (router 1) What I am having to achieve is that all packets goes to router 1 from internal IPs want to access internet will go out to that internet line but from 1 specific port, if router 1 detects packets from a specific source port (for ex: http port: 80), it will redirect that packet to router 2 and goes out to the internet from there.. I have found some documents which give solution that I will need a linux servers with 2 ethernet cards and then we plug both internet lines on that server and routing base on it but I do not want to do that because my boss does not want to have an extra work mantaining that server, besides, he says that the router itself already a linux one so why.. I tend to agree his points.. Can it be done or a seperate linux server acting as a router is a must? Thank you all in advance and really look forward in your replies.. I am newbie to linux network and it seems to be something out of my capacity to solve :( Your sincerely! Duc To

• How can something relevant to graphics completely kill a motherboard?

  - by leladax

  I was coding something in OpenGL and after a bug there was an 'OS slowed down' situation. After a few seconds the screen went blank and the laptop shutdown. Now not even a led turns on battery or not. It doesn't appear to be the AC or the battery since there was some battery when it died and when it's connected to the AC the laptop produces near the AC connection a very slight 'clicking' noise (very faint, one has to be very careful to notice it, I don't know if it was there forever tbh). I suspect the motherboard died, as in something from the point it gets AC or battery power and the point it actually feeds itself. But I can't figure out how that effect was produced by the OpenGL bug or graphics overheating. If the graphics died alone, it should at least give some indication that the laptop is barely alive, at least a led, a sound, anything, the laptop is instead completely dead (other than faint 'clicking' I mentioned). Does anyone have expert advice on this? I'm especially interested in any ideas connected to "graphics overheated/bugged ---- they killed motherboard". I have a very lengthy experience in that stuff as a hobbyist and it really puzzles me. It's not just a "AC died" situation I can easily google.

• How do I remove encryption from a VMware Workstation 7 image?

  - by Chad

  I successfully encrypted a VM image and confirmed it still runs. I then closed the VM and reopened it and confirmed the encryption password was valid and worked. However, now I want to un-encrypt the VM. When I choose that option, it asks for "your password". I assume this means the password I created when I encrypted it. It doesn't work. I can still open the VM with the password and run it. But, it refuses to remove the encryption using that password. Am I missing something? Is there a password that I don't know about? Some details: I created this image (using standalone converter; physical machine source) I converted it to ACE Converted back to a normal VM (un-ACE'd it) Encrypted it Cannot remove the encryption but can open it and run it As you can see... I am exploring the VMware features. Thanks for any guidance you can give.

• Client unable to access OWA website after temporarily changing SSL certificate on the server

  - by Lorenz Meyer

  I have the following issue: One client computer (Windows XP) cannot access the OWA website. All other client computers can (Except another one in the same remote office). How this happened: I temporarily changed the SSL certificate on the Exchange Server yesterday. After a few minutes, I reverted back, an now the same certificate that was installed for years is back again. During these few minutes, they were in OWA on this computer and got a certificate error. What exactly happens: Internet Explorer displays the error Internet Explorer cannot display the webpage, Firefox displays The connection was reset and Crome shows This webpage is not available. The connection to ... was interrupted. What I already did to try to get this working: Restart the client computer Restart the exchange server Deleted Internet Explorer browsing history In IE, Internet Options, tab Content, under Certificates deletes SSL cache Restored Internet Explorer to the default parameters I looked into certmgr.msc, but did not find a certificate related to the issue What could I do else to narrow down the origin of this problem (or better: resolve it) ? Can you give any advice ?

• How browsers handle multiple IPs

  - by Sandman4

  Can someone direct me to information on exact browsers behavior when browser gets multiple A records for a given hostname (say ip1 and ip2), and one of them is not accessible. I interested in EXACT details, like (but not limited to): Will browser get 2 IPs from OS, or it will get only one ? Which ip will browser try first (random or always the first one) ? Now, let's say browser started with the failed ip1 For how long will browser try ip1 ? If user hits "stop" while it waits for ip1, and then clicks refresh which IP will browser try ? What will happen when it times-out - will it start trying ip2 or give error ? (And if error, which ip will browser try when user clicks refresh). When user clicks refresh, will any browser attempt new DNS lookup ? Now let's assume browser tried working ip2 first. For the next page request, will browser still use ip2, or it may randomly switch ips ? For how long browsers keep IPs in their cache ? When browsers sends a new DNS request, and get SAME ips, will it CONTINUE to use the same known-to-be-working IP, or the process starts from scratch and it may try any of the two ? Of course it all may be browser dependent, and may also vary between versions and platforms, I'd be happy to have maximum of details. The purpose of this - I'm trying to understand what exactly users will experience when round-robin DNS based used and one of the hosts fails. Please, I'm NOT asking about how bad DNS load balancing is, and please refrain from answering "don't do it", "it's a bad idea", "you need heartbeat/proxy/BGP/whatever" and so on.

• How to host multiple FLEX applications in IIS7

  - by Devtron

  Hello, I manually deploy a FLEX application to my web server (IIS 7). There are two virtual directories, 1.) Default 2.) myFlexApp1. myFlexApp1 is where my working FLEX application resides. I now need to deploy a different FLEX application (let's call it myFlexApp2) to the same web server. I set up a virtual directory for [myFlexApp2] and it complains about the "bindings" using port 80, which is already used by [myFlexApp1]. I have tried to give them separate host names in their bindings properties. For example, myFlexApp1.mydomain.com and myFlexApp2.mydomain.com. I can never get [myFlexApp2] to show from an external browser. I was able to get only one or the other to display, but never could run both. Here is what I need: myFlexApp1.mydomain.com -- myFlexApp1 calendar.mydomain.com -- myFlexApp2 test.mydomain.com -- myFlexApp1 where test.mydomain.com is the default URL. Is this possible? What am I doing wrong? I even tried to edit the hosts file in [C:\Windows\System32\drivers\etc] but that didnt work either. How can I serve up two FLEX applications on IIS 7? It shouldn't be this hard!
