Created page with "C:\app\watchAuth0LDAPConn.ps1 ``` $url = "127.0.0.1:49948" $sleep = 3 Write-Output "Starting $url connection watcher." while($true){ try { $R = Invoke-WebRequest $..."

New page

C:\app\watchAuth0LDAPConn.ps1
```
$url = "127.0.0.1:49948"
$sleep = 3
Write-Output "Starting $url connection watcher."
while($true){
try {
$R = Invoke-WebRequest $url
}
catch {
$_.Exception.Message
Write-Output "URL $url is unresponsive. Restarting Auth0LDAP service."
}
Start-Sleep -s $sleep
}

# New-Service -Name "Auth0LDAPAppHealthWatcher" -BinaryPathName C:\app\checkTcpPort.ps1
# start-service Auth0LDAPAppHealthWatcher
```

Use nssm.exe to create service
```
$Binary = (Get-Command Powershell).Source
$Arguments = '-ExecutionPolicy Bypass -NoProfile -File "C:\app\watchAuth0LDAPConn.ps1"'
.\nssm.exe install watchAuth0LDAPConn $Binary $Arguments
```

```
start-service watchAuth0LDAPConn
get-service watchAuth0LDAPConn
```

you may be able to use sc.exe but I had issues with New-Service command
