This version of System Recovery Options is not compatible with this version of windows

I was trying to repair a Windows Server 2008 R2 server and got a error  at the System Recovery Options screen when booting from the OS DVD.

This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disk that is compatible with this version of Windows

The error read “This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disk that is compatible with this version of Windows.”.

The problem was that I was using the correct recovery disk, so why was windows reporting this. In this case the error is misleading and really meant that it could not find the windows installation. This is because the drivers for the RAID controller card was not included with the windows recovery disk.

To fix this problem you first need your RAID controller drivers on a USB drive plugged into the server. You may need to download the drivers from the hardware vendor of you server / raid controller card if you do not have them already.

Then boot the server from the Operating System DVD and Select Repair your Computer. Continue reading

Windows 10 VPN before log in for domain users

How to create a VPN connection before logging in to Windows 10

I just thought I’d post a quick help guide for those struggling with remote sites that have no site-to-site VPN. For what ever reason the site has no VPN you can get new users logged into a domain.

The situation

I’ve been looking after a site that has remote users and due to the fact the remote office is shared with other companies, it is not possible to set up a site-to-site VPN. In the past we have setup new computers at head office, got the user to log-in and then ship the PC to site. Once on the remote site, they can log in and connect to the VPN to get access to the network shares. This is becoming more difficult as new users are starting at the remote location and need to log in for the first time from there. Continue reading

Exchange 2013 Uninstall Error – generating an offline address book

“This mailbox server is responsible for generating an offline address book”

I was trying to uninstall Microsoft Exchange 2013 after moving to Exchange 2016 but kept getting the error “This mailbox server is responsible for generating an offline address book” in the Readiness checks.

I ran ‘Get-Mailbox – Arbitration’ to verify all the mailboxes had been moved.

Nothing appeared to be pointing at the old server and I could not find any mailboxes on the server.

In the end I ran ADSIEdit and found under Configuration > services> Microsoft Exchange > First Organisation> Address List Container > Offline Address Lists that the Offline Address Book had a reference to the old server. Continue reading

Solved – Dell PowerEdge R430 and installing Windows 2016 from USB

Today I got a delivery of a new Dell PowerEdge R430 and needed to install Windows 2016 Standard on it.

I downloaded the ISO from Microsoft and created a bootable USB pen using the Windows 7 USB/DVD Download tool, but Dell’s LifeCycle controller refused to recognise the USB drive.

Dell, if you’re listening, please let us install from USB through the Lifecycle Controller !

The ISO was 5.47 Gb so would not burn to a standard DVD and I needed to deliver this server to my client the following day.

All the hard drives appeared to have plenty of space and the backup drives were new and also had plenty of space.

PCI Compliance failure due to Clickjacking threat

Recently I’ve come across a new PCI compliance failure “Web Application Potentially Vulnerable to Clickjacking”.

Clickjacking PCI compliance failure

What is Clickjacking ?

Clickjacking uses IFrames to basically put a tranparent layer over a website and therefore can hijack the clicks and keystrokes the user enters.  This is also known as a “UI redress attack” as it is changing the Users Interface.

This means users can be fooled into giving up usernames and passwords when they think they are logging into legitimate web sites, not realising there is a layer intercepting these details between them and the legitimate site. Continue reading

Security Metrics PCI Compliance Site Failed

One of the companys I work with take Credit Card payments and therefore want to be PCI compliant, and use security metrics to scan the network for compliance.

Lately they’ve been failing their online scan for a few reasons.

  1. Windows 2003 has been detected and that now unsupport
  2. TLS version 1.0 is still enabled
  3. SSL RC4 is still enabled.

Windows 2008 server Hyper-V host and corrupted windows install

I had a bit of a worrying time last week when a colleague upgraded an old (but live) Dell PowerEdge R310 server running Hyper-V with some new RAM.
He powered down the old server, upgraded the RAM and booted the server back up.
A few minutes later he was looking at the screen loading windows, when it failed. He put the DVD and tried to repair windows but when he got to the  System recovery window it didn’t show any installations of Windows.
He then looked to restore from backup to another server to get the Hyper-V clients running while we fix this server.

Yes, you know what’ coming here, the latest backup we had was over a year old. Our client had not swapped out the drives for that length of time and something had corrupted the one drive that was plugged in.  Windows Backup was reporting successful backups, but when you try to restore, you cannot see any dates to select from. An investigation for another day I think !
