Server 2008 - Remotely adding/removing users from Groups

runas /user:domain\username "psexec \\server net localgroup test domain\username {/add or /delete}"

Remotely installing SNMP on Server 2008

1. On one server, install SNMP 2008 (C:\ocsetup SNMP), configure the service and export HKLM\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ to C:\snmp.reg


2. Create a batch file that will a). import the key exported from step 1. b). delete the 1 value which needs to be removed to allow 'Any host' to connect to the SNMP service.
reg import C:\snmp\snmp.reg
reg delete HKLM\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\PermittedManagers /v 1 /f


3. Copy these files to all of the servers via this script (make sure to create the C:\computers.txt and populate):
Const ForReading = 1
Const OverwriteExisting = TRUE
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\computers.txt")
Do Until objFile.AtEndOfStream
    strComputer = objFile.ReadLine
    strRemoteFile = "\\" & strComputer & "\C$\snmp.reg"
    objFSO.CopyFile "C:\snmp\snmp.reg", strRemoteFile, OverwriteExisting
Loop


4. Use psexec to execute the snmp.bat on each server via:
C:\runas /user:domain\username "psexec \\server\ C:\snmp.bat"


5. Use snmpwalk from this page and run
snmpwalk -v 1 -c community-here 127.0.0.1

6. Remove all of the files using:
Const ForReading = 1
Const OverwriteExisting = TRUE
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\computers.txt")
Do Until objFile.AtEndOfStream
    strComputer = objFile.ReadLine
    strRemoteFile = "\\" & strComputer & "\C$\snmp.reg"
    objFSO.DeleteFile strRemoteFile
Loop


Steps 4 & 6 can be improved by getting the @file command with psexec, but since it's paired with runas it might be tricky to get that to work.
