Microsoft have recently announced a new edition to their Office suites: Office 365. While there isn’t a great deal of information available it looks set to combine the elements of the Microsoft Online Services suite (Exchange Online,  Sharepoint Online and Lync Online) with the desktop Office suite (at least the Enterprise level product has the desktop suite, the Small Business only has the browser based Office Web Apps) .

The pricing structure is a monthly subscription/rental, reflecting the online ‘cloud’ based nature of the Online Services applications. While we can see the benefit for those who are already using or planning to use Microsoft Online Services (essentially a free licence for Office Professional Plus per user whilst they are subscribed) at present we cannot see any major attraction for new customers.

Whilst we still have many unanswered questions about Office 365 (primarily regards deployment in terminal server environments) what’s evident is Microsoft are trying to entice more customers to embrace their Online Services ‘cloud’ based solutions.

If you have a load of Event ID 1023 for Perflib with the following Description:

Windows cannot load extensible counter DLL TermService, the first DWORD in data section is the Windows error code.

The fix is a simple
Start > Run > lodctr tslabels.ini

Or run that in a command line to check it’s run as expected. This fix took too much digging around the internet to find so here it is a little clearer.

Exchange 2010 has been available for a while now, here at Glo Networks we’ve been using it since the beta testing stage and we’ve found many of the new features to be great, both for administrators and users.

Now SP1 for Exchange 2010 is released today, and not only does it include all the roll-up updates and bug fixes released so far but it also includes some handy new features. Several of the features are to make administrating the Exchange server more efficient (some new features in the Management GUI) but there are a few that users will enjoy.

One big benefit of the SP is it includes the ability for user to share their calendars, from OWA (which has been improved again and looks very nice!), via HTML or iCal. This means when someone asks you when you’re free for a meeting you could simply send them a link to your calendar for them to compare with theirs. Just imagine: no more ‘I can do Friday’ ‘Well I can’t make Friday but how about Monday..’ type conversations!

Recently one of our customers has been playing with Hyper V, creating virtual machines for testing purposes. We have advised them in this and have guided them through using Hyper V, and it’s features and functions. One of the questions asked by the customer was about snapshots. ‘Why not use them for backups?’ they asked.

For anyone using Hyper V, Snapshots can be a very handy tool. Allowing the swift roll back of a VM to a previous state, they were intended to be used mainly for development and testing environments. They do have their uses for production environments too however, for example; if you wished to perform a potentially risky update on software installed on a virtual machine a quick snapshot before would allow you to do so safe in the knowledge you can revert to before the update simply by loading the snapshot.

One thing that snapshots should not be used for is a substitute for backups. Although they may on the surface seem ideal for this purpose there are a few reasons this is not recommended.

• They do not provide protection against problems that may occur on the host server (the one running Hyper-V), such as a hardware problems on the physical computer or a software-related issues in the operating system.
• Programs running in the virtual machine will not be aware of the snapshot and when rolling back they will not be able to adjust correctly. For example a Exchange server on a VM which has reverted to a snapshot would expect to have connections to the same clients as it did when the snapshot was created.
• The snapshot files (.avhd) will not work, or at least not you will easily be able to revert to them, once they have been moved from their original location. This means that copying them away from the host machine (as you may if you were planning to use them as a backup) will essentially make them useless.

Please note: Our method of backing up HyperV VM’s involves the use of volume shadow copy snapshots. These are not the same as HyperV snapshots! For more info please see the following:

We’ve found that a recent Microsoft Security Bulletin which affects quite a few operating systems, can, in some cases, wipe IIS SMTP Server settings. In our case this caused problems for the server faxing software, which needed the correct settings applying once again after this update.

The bulletin is MS10-024, follow the link to be taken to the Microsoft site with full details. If you are affected by the problem and need a hand to resolve please don’t hesitate to contact us here at Glo Networks
