Extending Windows 2003 Server System Drive Without Reboot

EXTENDING WIN2K3 OS DRIVE

We’re in the middle of a VMware migration from 3.5 to 4.  Some of the older VMs have small C drives, and since Microsoft loves to release tons of patches, they’re running out of space.

In the past you could shut the VM off, attach the OS drive as an extra HD to another VM, increase the space and then use diskpart to extend it.  With VM Hardware v.7, it’s much easier!

Grab the ExtPart tool from Dell here.

1) Edit the VM’s settings to increase the disk size

2) Copy ExtPart to the VM and double-click to extract.  Default path is C:\Dell\ExtPart\

3) Check the Partitions before:

4) From a command-prompt, change to the ExtPart directory

5) Run extpart.exe

6) Enter in the disk you want to extend in lower-case, i.e., c:

7) Specify in MB of the amount of space you want to ADD, not the final total

8) Check partitions after

9) That’s all!

*note:  your partition in “Disk Management” will look funny until you quit and re-open Disk Managment:

Setting Specific Target DFS Environment

Setting Specific Target DFS Environment 

You can set a specific DFS-Target to be active but it won’t stick past the next logon I believe.

By default, the users will connect to the target in their 'site'

If you want to set a specific target as 'Primary" for everyone in a site

1.    Open up the DFS Management utility

2.    Open the Namespace the folder and target you wish to modify is under

3.    Select the folder you wish to control the targets on

4.    Right click on the target you wish to set as active

5.    Select the Advanced tab

6.    Check the "Override referral ordering" checkbox

7.    Select "First among all targets"

Edits:

This will allow users to Failover to other targets when needed.

It's also smart to enable the "Clients fail back to preferred targets" so if a user does fail over, they will switch back to the primary target once its back up.

You can also 'hard' control the targets by enabling/disabling them as needed. This works good when performing maintenance.
