PART I:

SERVER & SECURITY

Process Explorer

• Sysinternals.com tool

● Extensive listing of

processes

● Can use in place of Task

Manager

• LOTS of features

● Individual performance

graphs for each process

● Search for

files, handles, named

pipes, etc

● Takes a little practice

Memory Issues

• Memtest86● Runs a thorough, stand-

alone memory test for x86 architecture RAM

● Can build a bootable CD from an ISO image

● Allow to test for at least one full pass of all 9 tests

● If errors occur, try reseating or re-ordering RAM. If they still occur, replace.

● While Vista & Server 2008 have their own memory diagnostic tool built in, this works well for older O/S’s.

● Like XP, you crazy XP hold outs!

Rename en masse

• WSName.exe● Easy to use tool to rename workstations, in Workgroups and in

Domains!

● Rename remote machines

● Use batch files or VBScript along with this tool to rename multiple machines or an entire network.

● Very handy for migrations. Vista aware, W7 soon.

oldCmp.exe

• An ancient JoeWare tool that remains useful today!

• Command-line AD tool used to identify and remove stale computer accounts.

• Computer accounts reported on or removed based on last DS access.

● HTML reports

● DHTML reports

● CSV reports

ShellRunAs

• Windows Vista and Server 2008 no longer natively have the Run as… context menu item!

● Replaced with the Run as Administrator item.

● An omission that happens because of UAC.

• Lacking this, no way to run processes under alternate credentials.

• Get it back with ShellRunAs.● GUI and command-line exposure

Diskeeper Disk Perf. Analyzer

• Intended to drive you to Diskeeper’s for-cost defragmentation tools

● …but good for finding disk-based performance bottlenecks.

• Target multiple systems or entire network.

• Results show perf. loss reports based on fragmentation.

IOmeter

• Designed to measure disk subsystem performance.

• With disk being a major bottleneck for many applications, provides an understanding of relative speed.

SafePasswd.com

• Generates

difficult to crack

passwords.

• For users and

administrators.

• Point your users

to this web site

when they

complain.

KeePass

• Highly secured (AES & Twofish) password tool.

• Stores passwords in encrypted format, requires master password to unlock the contents.

● Can use master password plus separate encryption key

• Copy/Paste toclipboard capabilitywith timed wipe

• Nifty passwordgeneration tools

• Hide & unhidepasswords

Completely Disable UAC

• UAC had great intentions, but let’s be honest – it is truly annoying.

● Not that I’m recommending you ever do this. But if you wanted to completely disable UAC, split tokens, virtualization, and all the other new security features…

• Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options | User Account Control

● User Account Control: Admin Approval Mode for the Built-in Administrator account (Disabled)

● User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode (Elevate without prompting)

● User Account Control: Detect application installations and prompt for elevation (Disabled)

● User Account Control: Only elevate executables that are signed and validated (Disabled)

● User Account Control: Run all administrators in Admin Approval Mode (Disabled)

● User Account Control: Switch to the secure desktop when prompting for elevation (Disabled)

● [This is under “other”] User Account Control: Only elevate UIAccess applications that are installed in secure locations (Disabled)

The RAID 1 Undo

• Personally, my favorite little “trick”

• Most server-class equipment includes hardware RAID● However, most admins are used to RAID 5 for its expandability

• Use “The RAID 1 Undo” immediately prior to major software changes, like patching. Here’s the trick:

● Just before the patch, yank one of the drives.

● If the patch goes well after the reboot, reseat the drive and let the RAID rebuild.

● If the patch doesn’t go well, then power down the machine, pull the now “bad” drive and drop in the “good” drive.

● Once the system restarts, reseat the “bad” drive and let the RAID rebuild.

SpecOps Gpupdate

• Tool that augments ADUC with additional right-click functionality for managing computers.

● Gpupdate

● Restart

● Shut Down

● Start (via WOL)

● Immediatelyinstall WSUSupdates

● Graphicalreporting

The PSTools

• SysInternals Suite of Tools● Should be an important component of any administrator’s quiver

● UNIX-like tools

• Psexec – Remote command execution

• Psfile – List files opened by remote systems

• Psgetsid – Get computer or user SID’s

• Psinfo – Get local or remote computer information

• Pslist – List local or remote running processes

• Psloggedon – Lists logged on users

• Psloglist – View local or remote Event Logs

• Pspasswd – Change local or remote passwords

• Psservice – Views/Modifies local or remote service config

• Psshutdown – Shutdown/Reboot local or remote machines

• Pssuspend – Suspend local or remote processes

Extremely

Useful!

PSExec

• Easily the most useful of all the PSTools

• Launch remote processes:

Psexec \\<ComputerName> iexplore.exe http://www.hampsterdance.com

• Start remote command shell:

Psexec \\<ComputerName> cmd

• Verify Terminal Server logged-on users:

Psexec \\<ComputerName> quser

Hyper-V Monitor Gadget

• Once Hyper-V is installed, it is challenging to determine the state of virtual machines from the server console

• This sidebar gadget shows virtual machines and their status

• Enables Turn Off | Shut Down | Save | Start functionality

• Can monitor multiple serversreport on status, and RDP.

• Install to your managementVista workstation.

PART II:

FILE & DISK

icacls

• Icacls > xcacls.vbs > xcacls > cacls

• Configuring perms at the command line is harder than you’d think.

• This is due to how Windows permissions themselves are now very complex.

• Icacls can configure DACLs, SACLs, and now Integrity Levels

• Must set permission on (OI)(CI) for object and container.

icacls

• Icacls C:\Shared /inheritance:r /grant:r “Domain

Users”:(OI)(CI)R /grant:r “File

Admins”:(OI)(CI)F

• Icacls C:\Shared\Finance /inheritance:r /grant:r

“Finance Users”:(OI)(CI)R /grant:r “File

Admins”:(OI)(CI)F

• Icacls C:\Shared\Finance\Budget /grant:r

“Budget Users”:(OI)(CI)M

• Icacls C:\Shared\Finance\Metrics /grant:r

“Metrics Users”:(OI)(CI)M

• Icacls C:\Shared\Marketing /inheritance:r

/grant:r “Finance Users”:(OI)(CI)R /grant:r “File

Admins”:(OI)(CI)F

• Icacls C:\Shared\Marketing\Product /grant:r

“Product Users”:(OI)(CI)M

• Icacls C:\Shared\Marketing\Restricted

/inheritance:r /grant:r “File Admins”:(OI)(CI)F

/grant:r “Restricted Users”:(OI)(CI)M

Visual Tool for ACL’s

• AccessEnum● Visual tool for seeing ACE’s in ACL’s

• Can also be used as a NFS or NAS device.

StarWind iSCSI SAN Software

• Windows-based iSCSI Target.

• Works with ESX and Hyper-V hosts

• Fully Windows Failover Clustering capable• (I like it better than OpenFiler…)

WinSCP

• Transferring files between UNIX/Linux and Windows machines is challenging from the command-line.

● Linux “smbclient” tool, but without all the command line nastiness.

• WinSCP is a graphical tool to do this.● Like FTP, but with security.

● Also supportsSFTP.

WinDirStat

• Graphical representation of file sizes across the disk.● Pac Man Rocks!

• Assists users/administrators with eliminating files.

• Odd looking at first, but the graphical view immediately draws the eye toproblem spots onthe disk drive.
