System admins and IT managers better take note of this. Microsoft is issuing stern warnings when migrating from the soon-to-be-unsupported Windows Server 2003 to Server 2012.

Additionally, the software giant has just discovered a new obstacle to migrations away from the dated operating system that it didn't know existed.

The issue manifests itself when users run Windows Server 2003 and Windows Server 2012 R2 domain controllers serving the same domain.

Some people who do so may also find thatthe Kerberos authentication protocol crashes as well, another source of guaranteed headaches.

When that happens, it becomes impossible for users to log in to servers, which isn't really going to help a migration effort.

Microsoft acknowledges the issue in a post titled “It turns out that weird things can happen when you mix Windows Server 2003 and Windows Server 2012 R2 domain controllers.”

That post adds that Microsoft is currently working on a fix, “but it’s going to take us some time to get it out to you.”

Just how much time it will take to create the fix isn't specified, however. The post admits the bug is a very big one, as running the two domain controllers in the same domain is just the kind of thing that can be necessary during a migration.

“We realize that upgrading an enterprise environment isn't easy, and much less so when your users start to have complex issues during your upgrade,” the post says.

The good news is that workarounds are possible, but those outlined in the post require a lot of working around to get when you need to go.

IT system admins and users experiencing the 'weird things' are advised to check with Microsoft for news about the hotfix when they become available.

A new microkernel that DARPA (The U.S. Defense Advanced Research Projects Agency) hopes to be bug free and used to protect drones from potential hacking will be released as open source tomorrow.

The formal-methods-based secure embedded L4 (seL4) microkernel was developed by Australian scientists at National ICT Australia (NICTA) and was part of DARPA's High-Assurance Cyber Military Systems program developed two years ago to stop hackers knocking unmanned drones out of the sky.

At the time, it was underlined as the most advanced and highly-assured member of the L4 microkernel family due to its utilization of formal methods that didn't impact performance.

A microkernel differs from monolithic kernels – such as the Linux and Windows kernels – by running as much code as possible – from drivers to system services – in user space, making the whole thing more modular and in theory, more stable.

Tuesday at noon Eastern Australian Standard Time (GMT +10), seL4's entire source code including proofs and additional code used to build trustworthy systems will be released under the GPL v2 licence.

Overall, a group of mathematicians from around the world and some aviation experts from the likes of Boeing and Rockwell-Collins joined a team of dedicated NICTA researchers on the project which involved the seL4 operating system designed to detect and stop hacking attempts dead in their tracks.

NICTA senior researcher June Andronick said the microkernel should be considered by anyone building critical systems such as pacemakers and technology-rich cars.

"If your software runs the seL4 kernel, you have a guarantee that if a fault happens in one part of the system, it cannot propagate to the rest of the OS and in particular the critical parts," Andronick said.

"We provide a formal mathematical proof that this seL4 kernel is correct and guarantees the isolation between components," she added.

NICTA demonstrated in a video how a drone which runs the platform could detect hacking attempts from ground stations that would normally cause the flight software to die and the aircraft to crash.

"What we are demonstrating here is that if one of the ground stations is malicious, and sends a command to the drone to stop the flight software, the commercially-available drone will accept the command, kill the software and just drop from the sky," Andronick said.

The researchers' demo drone would instead detect the intrusion attempt, flash its led lights and fly away. This could ensure that real drone missions could continue in the event of hacking attempts by combatants.

Andronick added that seL4 would come into play as the team added more functionality including navigation, autonomous flight and mission control components.

In depth information about seL4 was available on the NICTA website and within the paper Comprehensive Formal Verification of an OS Microkernel.

The IEEE (Institute of Electrical and Electronics Engineers) has launched a new study group in an effort to offer 25 Gbps Ethernet standardization a boost in speed.

But some might say-- ``Don't we already have Ethernet industry standards running at speeds higher than 25 Gbps?``

And the answer would be yes we do, but only as multiple links running in parallel. A 40 Gbps Ethernet connection is four 10 Gbps Ethernet serial links bundled together, and 100 Gbps Ethernet is ten links.

As switch vendor Plexxi notes, the 10x10 configuration that delivers 100 Gbps connections can be considered a placeholder, since the IEEE documentation for such speeds assumes 4 x 25 Gbps connections.

With hardware vendors already getting to work at the market-facing side of 25 Gbps Ethernet, the IEEE is now accelerating its own work on the standard.

In announcing the new study group, its chairman, Cisco's Mark Nowell said that its main focus will be on the MAC layer, adding that “the heavy lifting in developing and standardizing 25 Gbps Ethernet signalling technologies has been done as part of the development of 100 Gbps Ethernet. These technologies can be reused to enable a single-lane 25 Gbps Ethernet solution set for server interconnects for those future data centres.”

The MAC-layer standard will build on the physical layer specification, 802.3bj-2014, and the in-progress P802.3bm task force that's defining “4 x 25 Gbps operation for signal traces for chip-to-chip and chip-to-module applications, as well as for 25 Gbps operation over four parallel multi-mode fibres”, the IEEE says.

VMware has revealed some information on its AirWatch acquisition it did in January. AirWatch is a mobile device management system that integrates with the Instagram site.

The new system will integrate in VMware's end-user computing group, where it looks set to form a part of the system administration side of the equation.

VMware's CTO Colbert tells us a bit how this will work-- “Users should have a simple one click experience, without the need for entering usernames and passwords, or requiring a separate VPN connection to access internal resources. Also, we focus on a common set of functionalities and features that can apply consistently to all platforms – app management, content management and device management. Similarly, there should be common functions – like identity, network access control, and social – that should be integrated across our product set to ensure a consistent user experience across the whole suite.”

There's not much new there, except for the fact that AirWatch makes it possible for VMware to do all it says it wants to do for desktops on mobile devices as well.

However, the new vision is rather cleaner than the old. An intriguing addition is “content management”, which Colbert says will be delivered in the form of the AirWatch Secure Content Locker (SCL), a product he says “provides a strong enterprise file sync and share foundation”.

So strong, in fact, that “we will be deprecating Horizon Data and are looking to consolidate Horizon Data functionality into AirWatch SCL,” he added.

And SCL won't just be about a corporate Dropbox either, as Colbert feels “users should be able to create ad-hoc discussion groups based on a file or set of files. Users should also be able to see how often one of their files is being viewed and by whom.

That capability would help connect users in a new way and enhance productivity. Which is just what EMC's Syncplicity services says about its system.

Colbert doesn't mention when this integration will be delivered, however. But the CTO does say more will be revealed at VMworld on August 24th.

Huawei's goal in the desktop virtualization market also deals with network function virtualization for telcom companies, according to Huawei CTO for data centre solutions Ron Raffensperger.

But the question is, can the company really crack the desktop virtualization market? The Chinese networking maker was this year's only new entrant to Gartner's Magic Quadrant for x86 virtualisation, a position that the analyst firm said reflects strong growth in its home nation and other developing economies.

To be sure, Raffensperger does agree with that assessment, telling us that emerging markets are keen to move from PCs to lower-cost mobile devices. That opportunity to offer a desktop virtualisation option presents plenty of opportunities, and the fact that Huawei runs 100,000 desktops in that mode using its own software doesn't hurt when the time comes to demonstrate proof of concept.

Huawei's cloudy suite is called FusionSphere and is based on the open source Xen hypervisor, which Raffensperger said Huawei has modified extensively to make it more secure, scalable and reliable.

“It does not bear much resemblance to Xen,” he said. Huawei has tweaked the software heavily because the opportunity that got it interested in virtualization was wireless carriers' interest in network function virtualisation (NFV), the practice of putting more intelligence in the network core instead of in premises equipment.

Naturally, delivering NFV often means running virtual machines to drive subscribers' desired applications.

As wireless carriers typically have many customers, Huawei's move into the virtualization segment therefore needed more scale than it felt when Xen could deliver in an unaltered form.

Which is not to say that the company is interested only in VDI and wireless carriers-- as most of us know, Huawei is a lot more ambitious than that.
