vSphere: Downgrading Guest ‘Hardware Version’

KB ID 0001458

Problem

I always assumed this was either not possible, (without using VMware converter,) or at least very difficult. I downgraded one of my test ESX boxes from 6.5 to 5.5 this week, and needed to lower the hardware versions on some of my VMs accordingly.

Solution

Connect to the host ESX server via SSH, then navigate to the VMFS volumes;

[box]cd /vmfs/volumes[/box]

Change directory so you are in the right ‘datastore’, locate the VMs folder, and change to that directory. You are looking for the VMs .vmx file, (shown below in green).

Edit the file using ‘vi’ and locate the virtualHW.version value, here it’s version 11 (ESX 6.0).

Here I’m changing it to version 10 (ESX 5.5).

Then remove the VM from the inventory, navigate to its .vmx file and select ‘Register VM‘.

Windows – Force into Safe Mode or”Cannot Boot into Safe Mode”

KB ID 0000521

Problem

With modern PC’s, the boot time is a LOT less than it used to be. There was a time when you would have a few seconds to press F8 when a Windows machine started and it would boot to “safe mode”. Now even with the reflexes of a fighter pilot, you are hard pushed to press the key before it says “Starting Windows”.

Solution

1. Boot Windows normally, and in the search/run box type msconfig, (or run from command line, whichever you prefer).

2. When msconfig opens select the boot tab > Select “Safe Boot” with the Minimal option selected > Apply OK > You will be asked to reboot.

3. The machine will now reboot into safe mode, when you have done what you need to do simply run msconfig again and Untick “Safe boot” >Apply > OK > Reboot.

Windows: How To Remove the ‘Shortcut Arrow’

KB ID 0000178 

Problem

Whenever I build a new machine, one of the first things I do, is open Regedit > Go to HKEY_CLASSES_ROOT > lnkfile and remove the “IsShortcut” Value, and voila! the annoying shortcut arrows are gone.

DONT DO THAT!

If you do, you will notice that you can no longer add shortcuts to the “Windows Explorer Favorites” (well you can but you can’t see them), also it disables (Grays Out) the Expand option for Favorites. It took me ages to find out that my registry hacking had caused the problem. so I put the registry key back again (restore it with this).

I even tried to use FxVisor to remove the shortcut arrows, and that didn’t work either.

Solution

1. Download this ZIP File.

2. Extract contents of the ZIP file to C:Icons

3. Navigate to C:Icons and run the RemoveArrow.reg file.

4. Accept the Warning.

5. Click OK.

6. Reboot – Arrows are gone.

Update 08/03/12 (Received Email form Steve Stroud)

Hi Pete,

Tried your method to remove the Shortcut Arrow from the desktop icons in Windows 8, using RemoveArrow.reg but how have a blank white document image on top of each icon, which look worse an the arrow! How do I change them Back. Looking forward to your reply. Regards Steve.

– Well I dont’t want to be the guy who breaks stuff! So I tested the procedure again an a fresh Windows 8 Box.

And it still worked fine, (that’s not helping Steve though), so to revert back simply run the following command (thats one line if it wraps), and reboot;

[box] reg delete “HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShell Icons” [/box]

Exchange – ‘The certificate status could not be determined because the revocation check failed.’

KB ID 0000484 

Problem

Seen on Exchange (with or without service packs) when you access the internet through a proxy server. Note: Exchange does NOT take its proxy settings from Internet Explorer.

Solution

1. To prove that the proxy is the problem drop to command line and issue the following command:

[box]netsh winhttp show proxy[/box]

 

If it says “Direct Access (no proxy server)” and you have a proxy server then that’s your problem.

2. Issue the following command:

[box]netsh winhttp set proxy proxy-server=”http={proxy IP}:{port};https={proxy ip}:{port}” bypass-list=”*.YourDomain.com”[/box]

3. Note: If at this point it all goes wrong (If you get it wrong, then the Exchange Management Console wont open! test it to make sure). To revert back to “no proxy”, issue the following command:

[box]netsh winhttp set proxy proxy-server=”http={proxy IP}:{port};https={proxy ip}:{port}” bypass-list=”*.YourDomain.com”[/box]

You only do this if it’s broken something!!

4. All being well your certificates should now display correctly.

Factory Reset Juniper SRX Firewall

KB ID 0001003 

Problem

If you manage to stuff up your firewall, or you have just done some testing and want to revert back to ‘as new’ here is how to do it.

Solution

1. Connect to the firewall either by console cable or via SSH, go to CLI mode then configuration mode.

[box] login: PeteL
Password: ************

— JUNOS 12.1X47-D10.4 built 2014-08-14 22:21:50 UTC

PeteL@Petes-SRX> cli

PeteL@Petes-SRX> configure
Entering configuration mode

[edit]
PeteL@Petes-SRX#

[/box]

2. Load factory defaults, at this point you cannot commit/save the configuration unless you set a password, so do that next.

[box]

[edit]
PeteL@Petes-SRX# set system root-authentication plain-text-password
New password: Password123
Retype new password: Pasword123

[edit]
PeteL@Petes-SRX#

[/box]

3. Save the changes then reboot.

[box] [edit]
PeteL@Petes-SRX# commit and-quit

commit complete
Exiting configuration mode

PeteL@Petes-SRX> request system reboot
Reboot the system ? [yes,no] (no) yes

Shutdown NOW!
[pid 1904]

PeteL@Petes-SRX>

*** FINAL System shutdown message from root@FW-01 ***

System going down IMMEDIATELY

[/box]

Reset To Factory Settings if the SRX is part of a Chassis Cluster (is in Failover mode)

1. If the firewall is part of the Chassis cluster then you need to the following before you can carry out the procedure above.

[box]

PeteL@Petes-SRX> set chassis cluster disable reboot

For cluster-ids greater than 15 and when deploying more than one
cluster in a single Layer 2 BROADCAST domain, it is mandatory that
fabric and control links are either connected back-to-back or
are connected on separate private VLANS.

{primary:node0}
PeteL@Petes-SRX>

*** FINAL System shutdown message from root@FWA ***

System going down IMMEDIATELY

[/box]

Completely Wipe the Juniper SRX

Alternatively you can also do the following.

[box]

root> request system zeroize
warning: System will be rebooted and may not boot without configuration
Erase all data, including configuration and log files? [yes,no] (no) yes

warning: zeroizing re0

root>

[/box]
