I downloaded the “Send Mail” VB10 sample from the Visual Basic 2010 Samples web pang and installed IIS (Internet Information Services 5.1) on my Windows XP Pro SP3 laptop. I was able to use the send mail sample instantly and went on to develop a more tailored program for sending mail. It all works great! However, when I take my laptop to different wifi network, with a different ISP (AT&T), something changes. My program still “seems” to work – it even gives me the “Mail Sent Successfully” message, but no mail makes it to it’s destination. Upon further investigation, I found that the outbound mail messages were accumulating in a folder called C:\Inetpub\mailroot\Queue.
What is causing this? Can I reconfigure something on IIS or within my VB10 program to make it work on AT&T? I have tried dozens of suggestions, but nothing has worked. I developed my program for the purpose of using it on the AT&T network – I need to have automated messages sent to me from that (AT&T) location. Can anybody help?
You need to setup IIS to forward the emails to your ISP so they can go out to the wide world.
Perhaps this KB article can help.

I have been facing some weird connection timeout issues in Visual Studio Code.
I am writing a simple web crawler to read a website using the requests and beautifulsoup4 packages in Python. I don't have any problem opening the URL in my web browsers (opens fine in Edge and Chrome), but when I say request.get(url), then the request always times out. Also, when I try to install some additional packages using pip, it always times out. But the corresponding PyPI page opens fine on my web browser.
The funny thing is - I am facing this issue only when I work out of my company's office. I don't have this issue at all when I am working from my home. There shouldn't be a system-wide firewall or a network firewall, because if there is, then the sites shouldn't be opening on my browsers too, right?
I went to VS Code Preferences and checked the settings there. There's no proxy set up. There is nothing specifically that would block network requests from inside VS Code. Here are some screenshots showing what VS Code Settings looks like.
I looked online and couldn't find much, since every question out there is regarding timeouts in SSH connections, which isn't relevant to me here. This official site here gives a bunch of URLs that need to be allowed by the firewall for VS Code to be able to connect to the network, but I don't know where to add them.
Is there something that I am missing? Any leads on how I can debug this issue? Or is it something that I'll have to take up with my company's network administrator?
TIA.
I am having really difficult time to cope up with the windows phone emulator.
My ultimate goal is to deploy my application and sniff http requests through fiddler.
I am on Visual Studio 2013 Update 4 on Windows 8.1
Problems which i face
Sometimes the emulator does not start at all and gets stuck "Window Phone OS is starting ".
Here first i get the message of "Attempting to modify switch settings" info dialog. I clicked on ok. Then i get Error dialog of "Windows Phone emulator is unable to connect to the windows phone operating system" "Object reference not set to an instance of an object "(Internal c# error). I click close and it gets stuck at "Windows Phone OS is starting".
if i get past this problem and my application gets deployed. I cannot connect to internet. Even a link in browser does not open.
Now for the rarest of rare times i am able to connect to internet. I am in no way able to sniff http request.
But sniffing is still my secondary problem, but my first issue is to get the emulator run and connect to internet.
Steps which i have performed to troubleshoot.
Hyper-V as a Windows feature is turned on.
My firewalls have been disabled.
I have removed the virtual machines and switch created by Hyper-V manager and let it be created through Visual Studio.
In network connections, disabled and enabled the vEthernet (Windows Phone emulator switch ).
Have also tried ipconfig/renew.
Have gone through lot of msdn posts, blogs, so questions but the behaviour of emulator is pretty inconsistent.
Is there any way i can get emulator logs/info ?
Any help to direct to me to any direction will be hugely appreciated.
UPDATE
only thing which is consistently working for me right now is disabling Hyper-V windows feature and then enabling it again.
Mind the expensive system restarts also. Then adding my user name to Hyper V admin group and then deploying the application.
So whenever i am changing my network i have to perform these steps. Definitely not sustainable
UPDATE 1
So now i have fiddler also acting as a man in the middle. Followed the steps here http://blogs.msdn.com/b/wsdevsol/archive/2013/06/05/configure-the-windows-phone-8-emulator-to-work-with-fiddler.aspx. Couple of thing to change here are the port number and to give the ip number instead of host name.
Also have fiddler always start first and then the emulator. Fiddler is able to sniff the requests happening in emulator. But my application http requests are not going through which is fine if i run without fiddler. I am currently looking into this.
Best Regards,
Saurav
Have you tried to run Visual Studio as Administrator? Sometimes, the user must have highest privileges to run Hyper-V.
Recently i installed Microsoft Visual Studio 2013 Preview Ultimate on Windows 7. Everything went smoothly except now i can't access www.microsoft.com and www.skype.com anymore. Tried latest IE10 and FireFox, both show blank page when accessing the above mentioned web sites. Firefox in its left bottom corner shows that it is waiting for ajax.aspnetcdn.com.
I'd really like not to reinstall OS on my machine, so i'd appreciate any idea how to fix this. For myself i tried to stop Firewall service and disable MS Security Essentials runtime protection, neither helped.
PS: I can access www.microsoft.com and www.skype.com from another machine in the same local network
UPDATE: i am using tfs.visulstudio.com as my TFS server and it opens fine if i am not signed in. But once i am trying to log in it opens blank, like browser is waiting for something (the same as for microsoft.com and skype.com). Something related to live ID?
Don't think this is the website to post this kind of question but try uninstalling VS2013 preview because you think that's causing the problem. Search in Google for people getting similar problem. I also don't think it is VS2013 because I can't think of anyway of how VS2013 would somehow disable you from going to a certain website. Make sure the sites weren't down at the time or if you're having something kind of Internet server issues.
skype is owned by microsoft, so you can't enter both microsoft pages. This could be related with some kind of ISP (Internet Service Provider) and not with VS2013, or you can try rebooting your router. Last thing i would do is traceroute both address and see where they fall.
I wanted to write this as a comment but I don't have enough reputation yet. Anyway, obviously trying to uninstall the program and trying again would be a good start as already mentioned, but you should also look inside your hosts file for any weird redirections some virus of malware might have set up. It's located at "C:\Windows\System32\drivers\etc" and you can open this inside notepad (might require notepad to be run as an administrator). Check to see if skype.com or microsoft.com are in there and are pointing to a different IP address. If they are you can just remove them and save the file (might require a restart to take effect). If still no luck you should try a livecd of a linux distro to make sure the problem is definitely inside your windows somewhere.
Let us know how it goes.
As part of my app, my users install a Window Service (msi file written in C#) that uploads data to me. These Windows servers are usually behind all kinds of firewalls etc. and run by IT staff so it's difficult to get in touch with anyone to debug.
What can I put inside my application that would make it easier to figure out things? I'm not looking to do anything that would be considered "shady" but here are some ideas I've thought:
Open log files that are relevant to me in a separate thread and stream it back up to the server
Setup some kind of reverse tunnel (not sure if there is a sane shell environment on Windows that I can connect to)
Any ideas or thoughts would be appreciated.
The author of the logging framework we use (the object guy's) has a service that might be useful for you.
You can debug .NET and native code through remote debugger with Visual Studio, see the post of John Robbins about it : http://www.wintellect.com/CS/blogs/jrobbins/archive/2010/06/15/vs-remote-debugging-across-workgroups-or-domains.aspx
Are there any tools available to monitor all current IIS requests on a server? I have some requests that are hanging, and I'd like to be able to identify which requests are hung, and then kill those specific requests, without affecting the rest of the requests, or the server itself.
I know that the IIS toolkit has a tool called "Requests Viewer" that does most of what I need, but it doesn't work on a 64 bit server.
Does anyone know of a tool that will do this?
Did you try the x64 Trace Diagnostics tools? I haven't run IIS Request Viewer before, but it certainly appears that it would work on x64....
Edit: Trace Diagnostics specifically calls out "Windows Server 2003 Service Pack 2 x64 Edition" as a supported OS. Perhaps you have some other issue? Are you sure you're on x64 (yeah - I know, it's an odd question, but sometimes you have to ask...it could be ia-64 (Itanium))
You might be able to install a proxy before IIS that logs the requests.
