Through March 2013, I’m running a set of IT and Web infrastructure masterclasses in Nottingham (in conjunction with PCM Projects), for people who don’t necessarily work in IT, but need to know (or would benefit from knowing) some of the basics.

The intended audience is small business owners or managers, where you may have to deal with IT contractors or staff and decide IT and web strategy, but you’re not comfortable that you know enough about it to make informed decisions. For example, there are an almost infinite number of ways to keep your business data accessible, secure, backed up, and away from prying eyes, but which way is best for you? How should you manage your website – should you pay someone else to design and host it, or bring it in-house? How should you handle email, on what sort of server? How should you plan for business growth? How do you protect your business from viruses, malware, spam, and hacking attempts?

These are the sort of questions that I will help you with – you don’t need any knowledge of IT or the web already, and because the groups are small – around 6 people – you’ll be able to ask questions and find out information specific to how your business operates.

You’ll then have enough knowledge to go to your suppliers or contractors, and ask the right questions, purchase the right services, at the right price.

There are four sessions, as below, and you can book yourself on them by visiting the eventbrite page for the events. Contact me for any further information.

 

Technically Speaking – 4 March

Topics to include: an overview of web/IT infrastructure and how it all fits together; an update on the current climate; domain names, analytics, and connections to social technology.

 

Email & Communication – 11 March

Topics to include: different service providers and set-ups (e.g., using hosted email, managing it in-house) and getting it all working for PCs and on mobile devices; good email practice, transferring data and keeping it secure.

 

Internet Security – 18 March

Topics to include: how to stay safe and keep trading; what are the threats – viruses, hack attacks, theft, loss of confidential or valuable data; keeping your business (and family) safe on the internet; and keeping your systems up to date and secure.

 

Data storage – 25 March

Topics to include: managing data storage and growth in your business; internal networks and cloud storage; back-ups; access controls, speed vs. reliability vs. cost.

First, run this command on a domain controller to extract the members of a security group:

net group "Security group name" >c:\groupmembership.csv

Then run this in an Exchange 2010 shell to extract the mailbox names from the database:

Get-Recipient -PropertySet ConsoleLargeSet  -ResultSize '9000' -SortBy DisplayName -RecipientType 'UserMailbox' -Filter '((Database -eq ''CN=DATABASENAME,CN=Databases,CN=Exchange Administrative Group (YOURADMINGROUP),CN=Administrative Groups,))' | Export-csv C:\userslist.csv

Then paste your names lists into excel in two columns, one named group membership, and one database users. Use the below formula in the third column to find the names that occur in both columns of data.

=VLOOKUP([first column entry,[Range E.G. A:A],1,FALSE)

The data coverage and bandwidth in Nottingham on Orange has been dismal for quite some time. I actually spoke to them last week about this, and they said that they’re aware of issues in Nottingham, as there are too few 3G masts, and one of them is faulty. They were rather hoping that things would improve once they merged the T-Mobile network into theirs (apparently around the 6th October), though as far as I can tell, it hasn’t.

The photo below shows two speed tests, run on iphones, with the same app, at the same time. The one on the left is on Vodafone, and the one on the right is on orange. You can see the Vodafone download speed is around 3Mbits/sec, which is comparable to ADSL. The Orange speed, on the other hand, is 0.24Mbits/sec; this is around just 6 times faster than a standard dial-up connection.
