Windows server system service overview and network port requirements

As security becomes ever more paramount and network administrators implement extra layers of security, including client PCs running personal firewall products, systems administrators and support staff need to know which ports and protocols Microsoft operating systems and programs require for network connectivity in a segmented network.

Microsoft have addressed this with Microsoft knowledge base article 832017, which details the essential network ports, protocols and services that are used by Microsoft client and server operating systems, server-based programs and their subcomponents in the Microsoft Windows server system.

To blog, or not to blog…

Self publication on the Internet has existed in various forms for many years, initially via newsgroups and then through the world wide web; however it is the rise of (we)blogging that has taken this to new levels, as software provides two key features:

  • Automatic page generation (using blog engines such as Blogger, TypePad or .Text).
  • Syndication, allowing aggregators to republish content and readers to keep track through online or offline blog clients.

In his recent article, harness the power of blogs, which appeared in IT Week, Tim Anderson comments that:

    “[Companies] have picked up the potential of the medium, and use it to their advantage, encouraging staff to blog. This does not come so easily to companies that have a culture of secrecy. But frankly, maintaining secrecy in the blog era is nearly impossible.”

At Conchango, many of our consultants have maintained their own blogs for some time now. Recognising the potential in the technology, company-sponsored blogging has recently been launched via the Conchango blogging community and blogging is encouraged, as noted last month by Scalefree in why professional service firms should blog. As far back as June 2003, in another IT Week column, Ken Young reported on why blogging is good for business and to quote part of the article:

    “Just like the use of instant messaging, personal publishing through weblogs is likely to get an icy reception in most firms concerned about security and ‘need-to-know’ issues. But smart companies will see that the advantages far outweigh the negatives. They will recognise that weblogging is a new form of knowledge management that has a vital time-based ingredients making it easy to see what another person is currently working on or discussing. If you need encouragement, bear in mind that weblogs are now a common feature in search results on Google”.

Blogging is big. That’s why so many of the major search engines now have a blogging presence – Google owns Blogger, Bloglines has been bought by Ask Jeeves and Microsoft (MSN Search) recently launched MSN Spaces.

But there is a dark side too – as Thomas Lee notes in his recent post on the dangers of blogging, some people may find it difficult to know what can and cannot be said without getting fired, leading to some bloggers being “dooced“. Blogger are even posting advice on how not to get fired because of your blog.

One example of an unlucky blogger is Ellen Simonetti (aka Queen of Sky), who was sacked for posting “inappropriate” pictures to her blog, diary of a flight attendant. From the pictures that I have seen, it appears that her employer took issue with the fact that she was wearing her company uniform and was on board one of their aeroplanes at the time that the pictures were taken. It seems to me (and remember that my blog entries are based on personal opinions and do not not necessarily reflect the views of my employer) that whilst invoking a disciplinary process may have been seen by her employers as necessary, firing her was complete overkill, especially as CNN reports that the same (cash-strapped) airline is now investing in sexier uniforms.

Quoting Anderson’s January comment in IT Week again:

    “Firms are just getting to grips with email privacy and appropriate use policies. Such policies should now be extended to blogs, before more people lose their jobs for breaching non-existent guidelines.”
    “It is also wise to consider the PR impact of sackings and litigation and of acknowledging problems and trying to fix them. The bottom line is that blogs work best for firms with nothing to hide. That means they help to drive up standards, which has to be good news.”

Luckily, my employer does have such a policy (and I have been conscious to follow it whilst writing this post on the pros and cons of blogging). For anyone thinking of instigating such a policy, Ray Ozzie’s Weblog has some useful advice and if you are thinking about starting out with a blog, check out digital diaries: the art of blogging.

IBM Rescue and Recovery with Rapid Restore

One of the technologies that I’ve been working with recently is IBM’s Rescue and Recovery with Rapid Restore. Another of IBM’s ThinkVantage technologies, this is provided free of charge with an IBM PC (and can be licensed for other OEM’s PC models).

In essence, Rescue and Recovery writes a backup of the entire PC hard disk to either a hidden partition on the local hard drive, a second hard disk, recordable media, network drive, or to a USB device. The first backup is a base image, then subsequent backups are differential. Backups can be scheduled and up to 31 backups can be stored before overwriting. In a recovery scenario, the process is simply booting from a rescue CD, which is easily generated and is not machine specific, or pressing the Access IBM button on selected IBM PCs, then selecting the backup to use and the file(s) to be recovered. Individual files, or the entire system, may be recovered, even preserving selected data and logon credentials written since the last backup.

All configuration settings are stored in an easily edited text file with full product documentation including customisation available in PDF format.

PCs with airbags – no joke!

IBM’s ThinkPad range of notebook PCs have always had some useful (and unusual) features in the detail (collectively dubbed as ThinkVantage technologies). For example, the ThinkPad T40 which I was using a few days back had a reading light built into the top of the screen to illuminate the keyboard whilst working in the dark.

We’re all used to cars with airbags to protect the occupants in an impact, but IBM have added an airbag to selected notebook PC models (I kid you not!). Known as active protection system, the feature adds an integrated motion sensor that continuously monitors movement of the notebook to temporarily stop the hard disk if necessary, helping to avoid data loss.

Like an airbag’s sensor, the active protection system can detect sudden changes in motion and park the disk read/write heads within 500ms – helping to prevent head or disk damage (as hard disks are most susceptible to damage whilst active). Once stabilised, the heads return to the normal position and continue working as usual. The technology is even adjustable for environments where vibrations are normal (e.g. on a train).

The email dash

Last week, I wrote a post about technology’s role in the demise of the English language and I was interested to read about the “correct” spelling of e-mail in this week’s IT Week. It seems that by popular usage today, email is 10 times more common than e-mail. As IT Week points out, the grammatically correct version (e’mail) is unlikely to catch on. Interestingly, Answers.com notes that email is the common spelling but has elected to continue the use of e-mail as it is easier to read.
