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.

Draytek Router Firmware Damage – the router will die after reboot

Draytek Router Firmware Damage

If you have a DrayTek with Firmware Damage and a warning “the router will die after reboot” read on to learn how to resolve it.

 

I have been flashing some DrayTek routers after I received an advisory from DrayTek about new critical firmware updates.

The first few went as expected with minimal downtime until one, a DrayTek 2830, disconnected midway through the upload of the firmware.

The web page of the router came back with an error “session disconnect”.

When I reloaded the page and logged back in I got the message:

Warning: Firmware Damage!!!

You must upgrade FW immediately, or the router will die after reboot!

Event ID 1500 1501 application event log spwebapp

I have just been looking at a problem with IIS (OWA outlook web access and sharepoint http://companyweb were not responding) and remote access to the RDS server had stopped. The application event log was full of event ID 1500 and 1501 for the user spwebapp.

The Windows SBS 2011 is running Exchange/OWA and IIS and has the remote gateway configured to redirect to the RDS server.

I restarted the remote gateway service which fixed the remote access problem.

The next problem was OWA and Company web not responding. I restarted IIS by running the IISreset from an admin command prompt but this didn’t change anything.

Event Id 1500 and 1501

As you can see the event were happening frequently (about 20 a second). I have no idea when this started as the log was full and overwriting older events.

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
