I need to change FlowControl Settings on 300 Servers. and this are a mixture of Dell r610; HP dl145 and IBM e326 servers and they all have dual Nics.

#Settings are subkeys under $key, I am trying to get all Nic cards set with *Flowcontrol = Auto Reg_SZ = 2147483648

$Key = "SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}", $true 

#Subkeys that have the Nic flow control Values below $Key. 0000
0001
0002
0003
0004
0005
0006
0007
0008
0009
0010
0011 Properties
 
I need to enumerate under $key and look for DriverDesc -eq to Broadcom*, hp*  after w/c I can run

$type = [Microsoft.Win32.RegistryHive]::LocalMachine
$regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($type, '$strcomputer')
$regKey = $regKey.OpenSubKey($key)
$strVal = $regkey.GetValueNames() | where {$_ -eq "*FlowControl"}

# if I was looking for specific subkey 006 or 007 under $key I can run this,
 
if ($strVal -ne $null) {
$regKey.SetValue('*FlowControl','2147483648','String')}

#problem is that the Nic Setting can be in any of this subkey so i really need to look for where the Nic Desc are and then do something like this against that subkey.

Foreach ($strvals in $strval)
$regKey.SetValue('*FlowControl','2147483648','String')}

I can't figure out the method to do like a reg query /s through  .NET Powershell Registry

If my explanation is confusing, please just let me know.
Thanks

I've called .Net Reg class, did functions, if and for loops allover in my script, then I found this!!
http://code.msdn.microsoft.com/PSRemoteRegistry

Only to find out that I can update this advance nic property change on all our 300 servers in a one line script!! hah! 

gc c:\powershell\host\server.txt | get-regvalue -hive localmachine -key "SYSTEM\CurrentControlSet\Control\Class\{4D36E9
72-E325-11CE-BFC1-08002bE10318}" -value *flowcontrol -ping -recurse | set-regstring -data 2147483648 –force

Just like what those Powershell Guru's said at Teched. " To those whose been fighting the use of powershell. It's not about why or how? Its when, if you work on any Microsoft system components, in whatever capacity you will use it!! NO CHOICE ITS EVERYWHERE!!"

Thanks for using the module edm365f31! Here's my version :) (remove -whatIf to apply changes):

$Key = "SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}"
Get-RegValue -Hive LocalMachine -Key $key -Recurse -Type String -Value *FlowControl | Where-Object {$_.Key -match -match '\\00[67]\\'} | Set-RegString -Data 2147483648 -WhatIf

If the *flowcontrol is missing I can just use new-regstring instead.

I was also told that its not a given that the Network Card will be in the 0006 or 0007 subkey(sometimes we also have add-on cards quad cards), with this bunch of servers it just so happen that most of them have dual nic cards.

What seems to be a better option is look first for the existing Value of the Nic Card in the subkeys and when its found, update *flowcontrol or if its missing create it.

Thanks for your help Shay.

Hi Shay I am trying to use these new registry cmdlets that you point to in the PowerGui Thread - http://powergui.org/thread.jspa?thr...start=105. They are just what I wanted and works well for local machines, however as soon as I try a remote machine I get the dreaded "cannot find the network path"


PS D:\powershell> Get-RegString -ComputerName "w002511552911" -Key "SOFTWARE\BroadSoft\BW Assistant\" -Hive LocalMachine -Value FriendlyVersion
Get-RegString : Exception calling "OpenRemoteBaseKey" with "2" argument(s): "The network path was not found.
"
At line:1 char:14
+ Get-RegString <<<<  -ComputerName "w002511552911" -Key "SOFTWARE\BroadSoft\BW Assistant\" -Hive LocalMachine -Value FriendlyVersion
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Get-RegString.

I have searched Google but still cant find an answer. I have run my powershell session with my elevated networked permissions. Any Ideas ? cheers Dene

Is the "Remote Registry" service running on the machine you are trying to connect to?
