Is there a way to set the UrlSegmentMaxLength value for Http.sys using appcmd/netsh or any other commandline utility?
I realize this is an old question, but in case someone stumbles upon this, here's PowerShell one-liner that either creates the key and sets the value or updates existing value.
if ((Get-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -ErrorAction SilentlyContinue) -eq $null) { New-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -Value 2048 -PropertyType DWord } else { Set-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -Value 2048 }
`
As for restarting, I found that this works well (no need to restart the server):
Stop-Service http -Force
Start-Service http
Start-Service IISADMIN
Start-Service W3SVC
I change this for my deployment in powershell
Set-ItemProperty -Path HKLM:\System\CurrentControlSet\Services\HTTP\Parameters -Name UrlSegmentMaxLength -Value 500
Restart-Service W3SVC -Force

I am wondering if there is way to use the Invoke-AzVMRunCommand to run a single command, rather than a powershell ps1 file?
As an example, I want to execute a single command... "C:\app\app.exe -c exit". Without the need to push a powershell commandlet to the system.
I am able to do this via the Azure Portal "RunPowerShellScript" and it works but would like to do it to multiple systems via the command line via Invoke-AzVMRunCommand. These systems do not share a command account that can be used.
According to Microsoft, here is the syntax...
Invoke-AzVMRunCommand -ResourceGroupName 'rgname' -VMName 'vmname' -CommandId 'RunPowerShellScript' -ScriptPath 'sample.ps1' -Parameter #{param1 = "var1"; param2 = "var2"}
I don't want to run a script, I merely want to be able to execute a command on the system. Is this possible?
There is no direct way of doing it. But, you can write a script block and generate a file from it and then run Invoke-AzVMRunCommand using that file and later on delete that file if required.
$Server = "server01"
[System.String]$ScriptBlock = {Get-Process}
$FileName = "RunScript.ps1"
Out-File -FilePath $FileName -InputObject $ScriptBlock -NoNewline
$vm = Get-AzVM -Name $Server
Invoke-AzVMRunCommand -ResourceGroupName $vm.ResourceGroupName -Name $Server -CommandId 'RunPowerShellScript' -ScriptPath $FileName
Remove-Item -Path $FileName -Force -ErrorAction SilentlyContinue
It's now possible to use the:
-ScriptString
... option, however you need to ensure that the Az version will support it.
Azure Pipelines as of 2022-07-21 don't support it:
"A parameter cannot be found that matches parameter name 'ScriptString'."
See the documentation:
https://learn.microsoft.com/en-us/powershell/module/az.compute/invoke-azvmruncommand?view=azps-8.1.0
So I am facing a situation when my project who is deployed on Azure cloud is getting high CPU most of the time it is 100% but after restarting the app, CPU usage goes to 10-15% for a few hours. I did try to use Kudu profiler but it did not help, most of the time it shows that some methods using 40% CPU when total CPU usage is 100%, but they are 2-3% when usage of CPU is low.
What a strange thing I noticed is some API controller methods if they don't get correct request BODY throws CGI/502 error, even though it should be throw Null reference exception because the method get the wrong body, the more interesting - to return CGI exception takes about > 2 min instead of 2sec as usually on my web service on local computer.
I went from S1 to S2 plan, same stuff, even though works a bit faster but azure insights show same 90-10% CPU usage.
First of all i would suggest you to write a code to get a crash dump of your server, you can refer this link for setting up .
Something like below would help you to write it in powershell.
$dumpFolder = "C:\crash-dumps"
if (!(Test-Path $dumpFolder)) {
mkdir $dumpFolder | Out-Null
}
$dumpKey = "HKLM:SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps"
if (!(Test-Path $dumpKey)) {
New-Item -Path $dumpKey | Out-Null
}
$dumpKey = "HKLM:SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\dotnet.exe"
New-Item -Path $dumpKey -Force | Out-Null
New-ItemProperty -Path $dumpKey -Name DumpFolder -Value $dumpFolder -PropertyType String -Force | Out-Null
New-ItemProperty -Path $dumpKey -Name DumpCount -Value 3 -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path $dumpKey -Name DumpType -Value 2 -PropertyType DWORD -Force | Out-Null
$dumpKey = "HKLM:SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\w3wp.exe"
New-Item -Path $dumpKey -Force | Out-Null
New-ItemProperty -Path $dumpKey -Name DumpFolder -Value $dumpFolder -PropertyType String -Force | Out-Null
New-ItemProperty -Path $dumpKey -Name DumpCount -Value 3 -PropertyType DWORD -Force | Out-Null
New-ItemProperty -Path $dumpKey -Name DumpType -Value 2 -PropertyType DWORD -Force | Out-Null
Based on the crash dumps we can easily understand what part is causing issue.
For the similar issue , you can track this request. Also try to degrade your application to V2.0.0 and see if it is still causing the CPU spikes. If yes then we need to look at your code as mentioned in the comments.
I am writing a Powershell script to add/remove/edit IP restrictions for websites using Powershell. So far I am able to add restrictions, however wondering the best way to edit an existing ip restriction.
Add
Add-WebConfiguration -Filter /system.webserver/security/ipsecurity -Value #{ipAddress=$ipAddress;subnetMask="255.255.255.255";allowed=$allowed} -Location $websiteName -PSPath "IIS:\"
Edit
I have tried various combinations of:
Set-WebConfiguration -Filter system.webServer/security/ipSecurity/add[#ipAddress='192.123.123.123'] -Name "ipAddress" -Value $ipAddress -Location $websiteName -PSPath "IIS:\"
Set-WebConfigurationProperty -Filter system.webServer/security/ipSecurity/add[#ipAddress='192.123.123.123'] -Value = #{ipAddress=$ipAddress;subnetMask="255.255.255.255";allowed=$allowed} -Location $websiteName -PSPath "IIS:\"
Is the best way essentially to clear all, and recreate each time?
I had the same problem and fixed it like this -
# Compose new entry
$value = #{allowed="true";ipAddress="192.168.0.1"}
# Add new entry to restrictions
Add-WebConfigurationProperty -Filter 'system.webServer/security/ipSecurity' -PSPath "IIS:\Sites\MySite\" -Location "MyService" -Name "." -Value $value -ErrorAction Stop
Automating some IIS stuff with Powershell. I needed to add an net.msmq binding using the approach listed here:
Why Powershell's New-WebBinding commandlet creates incorrect HostHeader?
Where I add using something like
New-ItemProperty -Path 'IIS:\Sites\Default Web Site' -Name Bindings -value #{protocol="net.msmq"; bindingInformation="server.domain.com"}
So now I need to automate removal of that binding (say the queue server changes). I have messed around with all the Collection cmdlets, and I cannot figure out a way to remove an item.
Get-ItemProperty -Path 'IIS\Sites\Default Web Site' -Name bindings
will return a collection. I can iterate through with ForEach, but I cannot seem to find the magic command to remove an item once I find it.
Any thoughts?
This worked for me:
$prop = (get-ItemProperty -Path 'IIS:\Sites\Default Web Site' -Name bindings).Collection | ? {$_.Protocol -ne "net.msmq"}
Set-ItemProperty "IIS:\sites\Default Web Site" -name bindings -value $prop
Remove-ItemProperty 'IIS:\Sites\DemoSite' -Name bindings -AtElement #{protocol="http";bindingInformation="*:80:DemoSite2"}
straight off the technet......
I hope someone can help, I am trying to enable enable "ASP.Net Impersonation" under the Authenticatuin section in IIS7, I have enabled other sections using the following command:
Set-WebConfigurationProperty `
-filter /system.WebServer/security/authentication/windowsAuthentication `
-name enabled `
-value true `
-location $SiteName
But I cannot find a similar command for setting up ASP.net Impersonation, I am guessing it has something to do with being ASP.net not IIS.
Any insight would be appreciated.
Try this:
Set-WebConfigurationProperty `
-Filter system.web/identity `
-Name impersonate `
-Value True `
-Location $SiteName
Use -PSPath instead of -Location.
Set-WebConfigurationProperty -filter /system.web/identity -name impersonate -value true -PSPath 'IIS:\Sites\Default Web Site\WebApp'
