Setting Web Site RequestFiltering/RequestLimits/MaximumAllowedContentLength

Ted Campbell — Tue, 09 Apr 2013 05:00:00 GMT

I am trying to set the Maximum Allowed Content Length for a web site under IIS 7.5 using Powershell 2 or 3. The only examples I have seen use appcmd ... This is easy to do with the IIS Manager UI by selecting the web site, double-clicking the 'Request Filtering' icon in the IIS section of the Features view and invoking the 'Edit Feature Settings' action. My need is to do this in a powershell script without relying on appcmd, if possible.

It seems that there should be a way to access and set this property but I have been unable to figure one or find one. Any help or advice is much appreciated.

Thanks.

Get Network Usage of a Particular Process

shreevardhan — Mon, 01 Apr 2013 05:00:00 GMT

Hi I want to get the network usage of a particular process (The bytes sent and Received) .Something which is there in Resource Monitor Under Network Activity.
I tried searching for a counter in get-counter but couldnt make it process specific.

can this be done using wmi or some performance counters?

Thanks

DComSessionOptions and CimSessionOptions in Workflow

stevlars — Thu, 07 Mar 2013 06:00:00 GMT

This question is a cross between WMI (via CIM) and Workflow. I hope I picked a reasonable forum.

My code looks for a specific service on a set of machines. I am able to get this to work using Get-WMIObject in a workflow as in the following:

workflow w1 {

param([string[]]$computerName)

foreach -parallel($computer in $computerName) {

Get-WmiObject -PSComputerName $computer -Class Win32_Service -filter "Name = 'Dhcp'" | Select -property Name, @{n="Computer";e={"$($_.SystemName)"}}

}

$computerList = @("Computer1"," Computer2"," Computer3")

W1 -computerName $computerList | Select-Object Name, Computer

I wanted to try using the CIM activities also and see if there is any performance difference. (I was suprised to see an indication for a small number of machines that the workflow seemed to perform faster than letting Get-WmiObject use its own job capabilities by passing in multiple computers.) I do need to fall back to DCOM being PowerShell is not on all the machines. This is what I came up with:

$computerList = @("Computer1"," Computer2"," Computer3")

$opt = New-CimSessionOption -Protocol DCOM

foreach ($computer in $computerList) {

$sd = New-CimSession -ComputerName $computer -SessionOption $opt

Get-CimInstance -CimSession $sd -ClassName Win32_Service -filter "Name = 'Dhcp'" | Select -property Name, @{n="Computer";e={"$($_.SystemName)"}}

}

That works fine also and uses the CIM cmdlets. Then I run into a problem making this a workflow. The following is my attempt:

workflow w2 {

param([string[]]$computerName)

$opt = New-CimSessionOption -Protocol DCOM

foreach ($computer in $computerName) {

$sd = New-CimSession -PSComputerName $computer -SessionOption $opt

Get-CimInstance -CimSession $sd -ClassName Win32_Service -filter "Name = 'Dhcp'" | Select -property Name, @{n="Computer";e={"$($_.SystemName)"}}

}

$computerList = @("Computer1"," Computer2"," Computer3")

w2 -computerName $computerList | Select-Object Name, Computer

That fails with:

Cannot convert value "Microsoft.Management.Infrastructure.Options.DComSessionOptions" to type "Microsoft.Management.Infrastructure.Options.CimSessionOptions". Error: "Cannot convert the "Microsoft.Management.Infrastructure.Options.DComSessionOptions" value of type "Deserialized.Microsoft.Management.Infrastructure.Options.DComSessionOptions" to type "Microsoft.Management.Infrastructure.Options.CimSessionOptions"."

+ CategoryInfo : InvalidArgument: (:) [], ParentContainsErrorRecordException

+ FullyQualifiedErrorId : InvalidCastConstructorException

+ PSComputerName : [localhost]

There is nothing in the help for New-CimSessionOption cmdlet that says anything about returning different types--hopefully the New-CimSessionOption activity would be the same. That may be the problem though. I looked at the types in MSDN and those two types do have a different set of properties (DcomSessionOptions has more).

Why would PowerShell need to convert the options when running in a workflow when it does not need to (or have a problem doing so) when not in a workflow?

Audit Script

AlexYoung — Wed, 20 Feb 2013 06:00:00 GMT

Hi,

I'm having problem with a script that is a simple WMI Inventory script that searches Active Directory for computer accounts and tests the connection and should go through checking wmi queries the problem is, i'm only getting the Computer Name, IP & MAC Address it's not going through the WMI queries.

Can anyone see anything incorrect.

PS v3 Has broken myscript in the WMI area

BhmJeep — Thu, 01 Nov 2012 05:00:00 GMT

Upgraded to V3 of PowerShell.

I have a script that runs on the first day of every month. One section of the script is gathering configs of our servers. Normally the output looks like this:

=======================

========================

With the appropriate settings pulled. Now it looks like this:

Can someone shed some light on what changed?

I have bitten off more than I can chew and can't see the forest for the trees...HELP!!!

Oseis — Tue, 21 Aug 2012 05:00:00 GMT

I have written the following script but each fix I do breaks 2 other things. For instance I am loading variable data to an .xlsx and it errored that the object was not a string. So I added .ToString method and it now says my passed variable ($computer) loaded using the Get-Content cmdlet is null!

Prior to using .ToString it went had no issues with the variable.

I am frustrated, stuck and out of time. Please help!

Oh yeah and the excel formulation broke as well.

How do I set the read/write WMI property SSLCertificateSHA1Hash?

clbarnett — Thu, 19 Jul 2012 05:00:00 GMT

I'm trying to programatically assign a certificate to an RDP-TCP connection object. If I run the following command:

get-wmiobject win32_tsgeneralsetting |`
get-member | where-object {$_.Name -match "SSL"} | format-list *

I get a result like this:
TypeName : System.Management.ManagementObject#root\cimv2\Win32_TSGeneralSetting
Name : SSLCertificateSHA1Hash
MemberType : Property
Definition : System.String SSLCertificateSHA1Hash {get;set;}

So, it looks like this is a read/write property. I can get the Hash of the certificate, but how do I actually *set* the SSLCertificateSHA1Hash property?

Basically, I'm trying to take a vbscript from here (http://blogs.msdn.com/b/rds/archive/2010/04/09/configuring-remote-desktop-certificates.aspx) and convert it to Powershell.

Re: How do I set the read/write WMI property SSLCertificateSHA1Hash?

clbarnett — Thu, 19 Jul 2012 05:00:00 GMT

Have you ever been in a situation where just the process of explaining the problem results in your own discovery of the solution? I did pipe it to get-member and the only methods aren't useful for picking the certificate. However, in the process of documenting what I had tried, I found my own mistake. I was doing the put() incorrectly. Heh.

This works:

$TSGeneralSetting = get-wmiobject win32_tsgeneralsetting

$Hash = "9090d0f754001cc304f012d05123e1fc6a1cc767"

$TSGeneralSetting.SSLCertificateSHA1Hash = $Hash

$TSGeneralSetting.put()

Extract list of computers then check for their DNS configuration....

Please can anyone help with my problem? I want to (quick and dirty) grab a list of active computers and retrieve their DNS server config.

I have this:

#Set date to compare

$CompareDate = Get-Date

$NumberDays=1

# Get the computers

$Comp = GET-QADCOMPUTER -SizeLimit 0 -IncludedProperties LastLogonTimeStamp | where { ($CompareDate-$_.LastLogonTimeStamp).Days -lt $NumberDays } | `

Sort-Object Name |

#Get the info

ForEach $comp

{$Name = gwmi win32_ComputerSystem |Select name | Out-File H:\test1 -append}

{$DNS = gwmi Win32_NetworkAdapterConfiguration |select DNSServerSearchOrder |Out-File H:\test1 -append}

But All I get is this:

ForEach-Object : Cannot convert 'System.Object[]' to the type 'System.Management.Automation.ScriptBlock' required by parameter 'Process'. Specified method is not supported.

At line:11 char:8

+ ForEach <<<< $comp

+ CategoryInfo : InvalidArgument: (:) [ForEach-Object], ParameterBindingException

+ FullyQualifiedErrorId : CannotConvertArgument,Microsoft.PowerShell.Commands.ForEachObjectCommand

What am I doing wrong? How can I get a list of computer names and their DNS servers?

Any help, greatly appreciated :)
