I need to get a list of the subnets from a 2003 dhcp server. Not dump the scope, just an output of the subnets them shelves and nothing else.

Download the DHCP module form microsoft
http://gallery.technet.microsoft.com/scriptcenter/05b1d766-25a6-45cd-a0f1-8741ff6c04ec

and save it as .psm1


$DHCPmodule = 'your path to the dhcp.psm1 file'
$DHCPServer = "name of the dhcp server"
Import-Module $DHCPmodule
$ScopeAddresses = Get-DHCPScope -Server $DHCPServer
foreach ($ScopeAddress in $ScopeAddresses)
{
Get-DHCPscope -Server $DHCPServer -Scope $ScopeAddress.Address| select-object @{N="Scope Name";E={$ScopeAddress.Name}},IPranges
}

From command line, I believe this will do it.  You can redirect the output to a text file.

NETSH DHCP SERVER SCOPE DUMP

NETSH DHCP SERVER SCOPE DUMP > scopes.txt

Netsh is built in to all DHCP servers 2003 and newer.  You don't have to download anything.

Here is a complete reference.

aa-denver: quick question, does it need to be running within the DHCP server?

I create the file Microsoft.DHCP.PowerShell.Admin.psm1, with the code from MS.

I put the files on my E:\, created and ran my new dhcplist.psm1 file in powershell, but on a workstation, not on the dhcp server itself.

Here is my file:

$DHCPmodule = e:\Microsoft.DHCP.PowerShell.Admin.psm1
$DHCPServer = "dhcp01sj"
Import-Module $DHCPmodule
$ScopeAddresses = Get-DHCPScope -Server $DHCPServer
foreach ($ScopeAddress in $ScopeAddresses)
{
Get-DHCPscope -Server $DHCPServer -Scope $ScopeAddress.Address| select-object @{N="Scope Name";E={$ScopeAddress.Name}},IPranges
}

And I get this error when running it:

Program 'dhcplist.psm1' failed to execute: No application is associated with the specified file for this operation
At line:1 char:16
+ .\dhcplist.psm1 <<<< .
At line:1 char:1

the script should be named as dhcplist.ps1 not psm1

psm1 is considered as module.

and yes you don't need to do anything on the dhcp server at all.

place the ' in front and the back of the path.

$DHCPmodule = 'E:\Microsoft.DHCP.PowerShell.Admin.psm1'

I see alot of these now. Also, where does this script output to? Can I get it dumped to a file?

Exception calling "Add" with "2" argument(s): "Item has already been added. Key

yes, by the way do you have powersehll 3.0?

$DHCPmodule = "E:\Microsoft.DHCP.PowerShell.Admin.psm1"
$DHCPServer = "dhcp01sj"
$Outpath = "your.csv"
Import-Module $DHCPmodule
$ScopeAddresses = Get-DHCPScope -Server $DHCPServer
foreach ($ScopeAddress in $ScopeAddresses)
{
Get-DHCPscope -Server $DHCPServer -Scope $ScopeAddress.Address| select-object @{N="Scope Name";E={$ScopeAddress.Name}},IPranges | export-csv $outpath -append
}

It has been tested and working in version 3

Try to go to the URL again and you should see copy code at the upper of the module

I think you missed some code when you are copying it

I copied it again by clicking the copy code and pasted it into the psm1 files. Looks to all be thee, just like before.

Still the same error messages.

That's weird

Try to useFQDN on your dhcp server
