PowerShell script for starting service and calling external script on remote machine.. I have most of the script written where it will start the w3svc service (which is what I need). Then I have added an extra elseif statement which will be used to call an external script for each machine listed in servers.txt. These may be powershell scripts or bat scripts.. All I am looking to do is look at servers.txt pull in the server name and then look at the name/location of the script residing on that server and run that script (on the remote server) with a start or stop command. I then am using a write-output in both operations to log exactly what has been done to a log file. Once I get this start script going then I need to use the same script to create a stop script which will use the same servers.txt to stop the w3svc service and run an external script with a stop argument.I am adding the code that I have already. I have tried to use WMI for this so I can leverage Powershell 3 but am not opposed to something different if it is cleaner. Also if there is anything that needs cleaning up in my current script I would appreciate the input.SVCStart.ps1# Setup trap to catch exceptionstrap [Exception]{write-error $("TRAPPED: " + $_.Exception.Message);}$start = $true#Assuming headers of "computername","operation","service" $computers = Import-CSV 'C:\scripts\servers.txt' foreach($computer in $computers){write-host $computer.computername $computer.service $computer.operation$objWMIService = Get-WmiObject -Class win32_service -computer $computer.computername -filter "name = '$($computer.service)'"if($computer.operation -eq "service"){if($objWMIService.state -ne "Running"){$objWMIService.StartService() | Out-Null;# Refresh the object instance $state = (Get-WmiObject Win32_Service -Filter "Name = '$($computer.service)'" -computer $computer.name).stateWrite-Output "$($computer.service) is ""$state"" on $($computer.name)" | Out-File C:\scripts\log.txt -append}}elseif($computer.operation -eq "script"){ $operation = [IO.File]::ReadAllText(".\external.ps1")Invoke-Expression $serviceWrite-Output "$($service.service) is ""$state"" on $($computer.name)" | Out-File C:\scripts\externallog.txt -append#As part of the ElseIF I have to call whatever script (may be different names) for each server listed under service. # As part of calling the EXTERNAL script I need to be able to give it a start of stop argument. # so this portion of the start script is going to be pulling from the third placement on server.txt under the header of service.#[the script will live on the remote server, this is where I want to use psremoting (or WMI If possible )to run the script *on* the remote server. } } Servers.txtcomputername,operation,service <--headersc1399,w3svc,c:\scripts\external.ps1 <--Server name, service, external script locationWn2k8srv,script,c:\scripts\dotwhatever.batXcutionDT,w3svc,c:\scripts\vstudio.ps1XcutionSRV,script,c:\scripts\getprocess.ps1Optional Information: Language (or Software): OtherAlready Tried: I have written most of the script but I cant figure out how to use invoke-expression to run the external script and add in a start argument..

hi please take a look at the assignment BrownVesseyNIBCOBigBang.pdfS2_2013_CIS8010_Assignment_3_Question Statement.pdf

This Needs to becompleted using Visual Studio Only! It can be downloaded for free here: http://www.microsoft.com/visualstudio/eng/downloads#d-2010-expressSTEP 1: Create a Multifile Project for the Composition Lab1. Add three classes to the project: a Filter class, a Capacitor class, and a Resistor class.2. You may use the Resistor class files from the Week 2 lab for this lab. 3. The Capacitor class should be modeled after the Resistor class for class members and operation. STEP 2: Filter-Class DefinitionThe Filter class should have, at a minimum, the following capabilities.a resistor-object data membera capacitor-object data membera cutoff frequency (in Hertz) of the RC filtermaximum and minimum cutoff frequencies, based on the maximum and minimum in-tolerance values of the capacitor and the resistor objecta filter type, either low pass or high passallow the user to enter new values for the filter, including6.1. resistor tolerance and nominal resistance; 6.2. capacitor tolerance and nominal capacitance; and 6.3. filter typeprovides the ability to write all capacitor, resistor, and filter data members to a formatted text file and allows the user to name the fileprovides the ability to read all capacitor, resistor, and filter data members from a formatted text file and allows the user to enter the file name and correctly handles a file-not-found errorSTEP 3: Test-Program OperationAll data-input and data-display operations (cin and cout) should be done in the function main() test program.The test program should instantiate at least one object of the class Filter.The user should enter values for all the data members of the Filter, Resistor, and Capacitor classes.The Filter class should then calculate and display the correct maximum and minimum cutoff frequencies.The test program should then display all Filter, Resistor, and Capacitor data members.Example Code: ( This example code is for all the file in the project it will be split over 7 diffent filess)#include <iostream>#include <string>using namespace std;class CResistor{private:double nominalValue;double tolerance;double minimumValue;double maximumValue;public:CResistor() {nominalValue = 100;tolerance    = 10;computeResistorLimits();}void computeResistorLimits() {minimumValue = nominalValue*(1-tolerance/100);maximumValue = nominalValue*(1+tolerance/100);}void enterResistor() {cout<<"Please enter value of resistance"<<endl;cin>>nominalValue;cout<<"Please enter tolerance of resistor (i.e. 10 for 10% tolerance)"<<endl;cin>>tolerance;computeResistorLimits();}void displayResistor() {cout<<minimumValue<<" Ohms <= R <= "<<maximumValue<<" Ohms"<<endl;}double getResistance(){return nominalValue;}};class CCapacitor{private:double nominalValue;double tolerance;double minimumValue;double maximumValue;public:CCapacitor() {nominalValue = 100;tolerance    = 10;computeCapacitorLimits();}void computeCapacitorLimits() {minimumValue = nominalValue*(1-tolerance/100);maximumValue = nominalValue*(1+tolerance/100);}void enterCapacitor() {cout<<"Please enter value of capacitance"<<endl;cin>>nominalValue;cout<<"Please enter tolerance of capacitor (i.e. 10 for 10% tolerance)"<<endl;cin>>tolerance;computeCapacitorLimits();}void displayCapacitor() {cout<<minimumValue<<" microFarads <= C <= "<<maximumValue<<" microFarads"<<endl;}double getCapacitance() {return nominalValue;}};class CRCFilter {private:CResistor  R;CCapacitor C;double cutoffFrequency;public:CRCFilter() {cutoffFrequency = 1/(2*3.1415*R.getResistance()*C.getCapacitance()*.000001);}void displayFilterParameters(){cout<<"The filter has:"<<endl;cout<<"R  = "<< R.getResistance() <<" Ohms"<<endl;cout<<"C  = "<< C.getCapacitance()<<" MicroFarads"<<endl;cout<<"Fc = "<<cutoffFrequency<<" Hz"<<endl;}};void main() {CRCFilter F1;F1.displayFilterParameters();
