Can't run vb.net application as administrator across network - vb.net

I have created a small application that auto elevates as administrator using the command:
requestedExecutionLevel level="highestAvailable" uiAccess="false"
This works fine if I run the application locally on the computer. However, if the computer tries to run my execuatable across the netork, it simply crashes on startup with a message "Do you want to send more information about the problem?" error. If I right click and run as administrator, my application will work and will prompt for admin credentials.
The folder I am running my application from (across the network) has full read/write permissions for 'everyone'.
My question is: Is there something I've missed? Why can I run my application locally and not get prompted but across the network crashes or requires admin?
Can anyone help explain what might be causing this issue?
UPDATE
I have checked my event viewer log and it shows the following:
Application: AutoUpdater.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Net.Sockets.SocketException

I don't understand why it is making reference to System.Net.Sockets?? But that is what seems to be crashing my app.

Make sure that the other computers attempting to run your application have the correct .Net framework versions installed. If users are able to open the executable, there shouldn't be any other issues with permission.
If you have verified the framework versions, see if there is anything in the error report that might point to a reason for the crash. A lot of times there may be something in there that can point you in the right direction.

.NET applications don't like to run from the intranet by default.
Try this:
Go to Control Panel -> Administrative Tools -> Microsoft .NET Framework 2.0 Configuration
Click Configure Code Access Security Policy link
Click Adjust Zone Security
Set the My Computer and Local Intranet to Full Trust
If this works, then it is a local security issue. If you need it scripted out, you can use the caspol exe that is in the framework. Sample
C:
cd %windir%\Microsoft.NET\Framework\v2.0.50727
CasPol.exe -pp off -m -ag 1. -URL Z:\folder\EXEName.exe FullTrust -n FriendlyNameOfEXE

VS2019 Cannot launch .NET Core ASP 2 web site and browse from another computer on the same network

I have been trying to browse a website run under IIS Express VS2019 from another computer on the same network. I see the following error.
Bad Request - Invalid Hostname
I found several discussions where people suggested adding bindings and I did try adding so many different bindings in applicationhost.config with specific hostname, IP, hostname+ip, wildcards. When I add any binding or modify the existing localhost binding VS 2019 start giving me the following error
Unable to connect to web server 'IIS Express'
I am running VS2019 as an admin. What else I am missing?
Here is what I discovered. I do not have admin privileges on my local PC. Our sysadmin had created a shortcut for me which launches VS2019 as an admin. However, the VS was still not run as elevated Admin privileges. Turns out, you need to be an admin, and you must right-click the VS2019 shortcut and choose Run As Administrator with a shield and say Yes to the warning. The shortcut wasn't doing none of that. Now my custom IIS Express bindings are picked up from applicationhost.config without any issue.

Windows could not start the Apache CouchDB service on Local Computer

I have installed CouchDB on my Windows machine but while starting the CouchDB service, I am getting a message like:
Windows could not start the Apache CouchDB service on Local Computer. The service did not return an error. This could be an internal Windows error or an internal service error. If the problem persists, please contact your system administrator.
As the service is not running, I am unable to access Fauxton too.
I am using Windows 7. CouchDB is 2.0.0. Port 5984 is not in use.
I don't think your question is a duplicate of https://stackoverflow.com/a/44107335/219187 because you are on Windows 7, and the problem described there is for Windows 10 with the creators update.
But maybe the solution fixes your problem as well? Here is the procedure:
Download the prelease build 2.2.4-101 from https://nssm.cc/download
Stop the CouchDB service through the Windows Services dialog (paused is not enough)
Overwrite nssm.exe in <CouchDbInstallDir>\bin with the one from the downloaded ZIP file (make sure you pick the right version 32 bit / 64 bit)
Start the CouchDB service
Issue it's happening since the last updates released by Microsoft. I'm not completely aware of what's causing it, but I think it's something related to CouchDB service not been able to start using Local Administrator rights.
However I've managed to start the service manually, by doing so:
Open Command Prompt - in the Search from the Start Menu or Task Bar type "cmd"
Run it as an Administrator - right click on the Command Prompt application and choose "Run as administrator" option /this is really IMPORTANT as it will allow the service to have administrator access/
Navigate to the folder where CouchDB is install - default path is "D:/CouchDB", but could be anywhere else; you have to find it
Go to the "bin" folder in there
Type "couchdb" as a command to start the service
You will see a message showing after this - "kernel-poll not supported; "K" parameter ignored"
If it adds some error messages after it or closes the whole terminal, you're making some things bad from this guide, so follow it strictly.
You can now open up the Fauxton application in the browser like normal from here - http://localhost:5984/_utils/
Keep in mind that you have to leave the cmd opened in order the service to be working as expected. As far as I saw no information was lost, so it's all good.
This is a temporary solution though, as we are waiting a relase from either Microsoft or Apache to solve the issue, or at least give us more explanation about it.
i just met the same problem.
the cause is space, you have to install CouchDB in a path without any space, even Program Files folder, because there is a space between Program and Files...

How can I publish an MVC 4 application on visual studio?

When I try to publish it I get the following error message:
Error 1 Web deployment task failed. (Could not connect to the remote computer ("..*.*"). On the remote computer, make sure that Web Deploy is installed and that the required process ("Web Management Service") is started. Learn more at: http://go.microsoft.com/fwlink/?LinkId=221672#ERROR_DESTINATION_NOT_REACHABLE.)
I dont understand why is it referring me to a remote computer, I've specified the destination URL as my own IP address. And I have web management service checked on windows features.
How do I solve this particular error?
Try to publish to the file system, if this works move the files into you wwwroot, normally c:\inetpub\www.
then go to start and run inetmgr to open iis configuration manager, if you see your folder there right click and convert to application, accept settings then right click / manage / browse and you should see your site or an IIS error that should be easy to debug.
I never use the deploy to IIS feature from VS as it's pants.
Good luck!

Configuring WCF in IIS7 & Windows 7

I am having a problem when I try to browse WCF service (.svc file) which is hosted in IIS7 & Windows7. It throws following error.
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
I tried to run ServiceModelReg, but it say I should have admin rights in order to run this, although I am admin on this machine.
Does any one know how to resolve this issue.
FInally....
I am able to resolve this issue.
I ran following two command and it solved the problem.
aspnet_regiis -i & ServiceModelReg -i
Even though I am admin on the machine, I need to run this 2 commands by right click and select 'Run as Admin'.
Your issued is answered here. Trying to be short:
When you start the command prompt, can
you right-click on the icon to open it
and select "Run as Administrator"? I
don't know exactly what's the logic
behind that, but on Vista there are
two kinds of administrative users, one
"normal" administrator and one
"elevated" administrator. I'd guess
the tool needs the second kind.
and second
Also, Why do you need to run
Servicemodelreg.exe on VIsta?
Officially this is not supported on
Vista. Instead you can go to WIndows
features menu throught Add remove
programs and enabled Http Activation
under .Net framework 3.0 feature.
This will enable everything you might
want to do via Servicemodelreg.exe.
Edit
And also here.
If you go into IIS Manager and double click on Handler Mappings do you have *.svc paths listed?
If they are missing this link may help http://msdn.microsoft.com/en-us/library/ms752252(v=vs.90).aspx

Stop IIS 7 Application Pool from build script

How can I stop and then restart an IIS 7 application pool from an MSBuild script running inside TeamCity. I want to deploy our nightly builds to an IIS server for out testers to view.
I have tried using appcmd like so:
appcmd stop apppool /apppool.name:MYAPP-POOL
... but I have run into elevation issues in Windows 2008 that so far have stopped me from being able to run that command from my TeamCity build process because Windows 2008 requires elevation in order to run appcmd.
If I do not stop the application pool before I copy my files to the web server my MSBuild script is unable to copy the files to the server.
Has anybody else seen and solved this issue when deploying web sites to IIS from TeamCity?
This article describes using an htm file named App_offline.htm to take a site offline. Once the IIS detectes this file in the root of a web application directory,
ASP.NET 2.0 will shut-down the application, unload the application
domain from the server, and stop processing any new incoming requests
for that application.
In App_offline-htm, you can put a user-friendly message indicating that the site is currently under maintainance.
Jason Lee shows the MSDeploy calls you need to use (plus much more about integrating these steps in your build scripts!).
MSDeploy
-verb:sync
-source:contentPath="[absolute_path]App_offline-Template.htm"
-dest:contentPath="name_of_site/App_offline.htm",computerName="copmuter_name",
username=user_with_administrative priviliges,password=passwort
After deployment you can remove the App_offline.htm file using the following call:
MSDeploy
-verb:delete
-dest:contentPath="name_of_site/App_offline.htm",computerName="computer_name",
username=user_with_administrative_priviliges,password=passwort
The msbuild community tasks includes an AppPoolController that appears to do what you want (though as noted it is dated and at present only supports IIS6.) An example:
<AppPoolController ApplicationPoolName="MyAppPool" Action="Restart" />
Note that you can also provide a username and password if necessary.
Edit: Just noticed that the MSBuild Extension Pack has an Iis7AppPool task that is probably more appropriate.
this is the fairly hackey workaround I ended up using:
1) Set up a limited-access account for your service to run as. Since I'm running a CruiseControl.NET service, I'll call my user 'ccnet'. He does NOT have admin rights.
2) Make a new local user account, and assign to the Administrators group (I'll call him 'iis_helper' for this example). Give him some password, and set it to never expire.
3) Change iis_helper's access permissions to NOT allow local login or remote desktop login, and anything else you might want to do to lock down this account.
4) Log in (either locally or through remote desktop) as your non-admin user, 'ccnet' in this example.
5) Open a command terminal, and use the 'runas' command to execute whatever it is that needs to be run escalated. Use the /savecred option. Specify your new administrative user.
runas /savecred /user:MYMACHINE\iis_helper "C:\Windows\System32\inetsrv\appcmd.exe"
The first time it will prompt you for 'iis_helper's password. After that, it will be stored thanks to the /savecred option (this is why we're running it once from a real command prompt, so we can enter the password once).
6) Assuming that command executed OK, you can now log out. I then logged back in as a local admin and turned off the 'ccnet' user for local interactive login, and remote desktop. The account is only used to run a service, but no real logins. This isnt a mandatory step.
7) Set up your service to run as your user account ('ccnet').
8) Configure whatever service is running (CruiseControl.NET in my case) to execute the 'runas' command instead of 'appcmd.exe' directly, the same as before:
replace:
"C:\Windows\System32\inetsrv\appcmd.exe" start site "My Super Site"
with:
runas /savecred /user:MYMACHINE\iis_helper "\"C:\Windows\System32\inetsrv\appcmd.exe\" start site \"My Super Site\""
The thing to note there is that the command should be in one set of quotes, with all the inner quotes escaped (slash-quote).
9) Test, call it a day, hit the local pub.
Edit: I apparently did #9 in the wrong order and had a few too many before testing...
This method also doesn't completely work. It does attempt to run as the administrative account, however it still runs as a non-escalated process under the administrative user, so still no admin permissions. I didn't initially catch the failure because the 'runas' command spawns a separate cmd window then closes right away, so I wasn't seeing the failure output.
Its starting to seem like the only real possibility might be writing a windows service that will run as admin, and its only purpose is to run appcmd.exe, then somehow call that service to start/stop IIS.
Isn't it great how UAC is there to secure things, but in actuality just unsecures more servers, because anything you want to do you have to do as admin, so its easier to just always run everything as admin and forget it?
You can try changing the Build Agent Service settings to log-on as a normal user account instead of SYSTEM (the default), this can be done from the services control panel (Start | Run | services.msc).
If it doesn't help, you can also try configuring the appcmd to always run elevated, refer to this document for details.
In case such option is not available for appcmd or it still doesn't work, you can disable UAC completely for this user.
Here you go. You can use this from CC.NET with NAnt or just with NAnt:
