How long should my server last?

Network DiagramIt is the time of year that most small business owners are revising their plans for the upcoming year.  Technology equipment and software are key elements of that plan.  

 A common question we receive is: How long should my server last and at what point should I seriously consider replacing it?

 Onsite Logic recommends planning for a 4-5 year upgrade cycle for most small business owners.

 The traditional rule of thumb is to expect 5-7 years for the life of the server hardware.

 But the age of the equipment is not the only factor to consider:

  1. If using the server is core to your business, are you losing efficiency because of the slowness of older equipment?  We are installing servers this week with a minimum of 8GB of memory and have put in systems with 24 and 32 GB of memory and higher (not drive space, memory)
  2. How well has the server been maintained?  Has someone, at least once a month, taken care of issues as they arise, even ones that may not be visible to users but that are logging errors in the event logs?  Is it patched up-to-date monthly?  Have regular maintenance items, such as disk maintenance, clearing temp folders, blowing out the systems, happened regularly?
  3. How stable is the power to the building?  Are you using a voltage regulator?  Does your UPS kick in more than once per year?
  4. Are there any problems, noises or errors?
  5. How confident are you in your backup?  Do you know where all of your CD’s, license keys and account passwords are?

 In a single server environment, you have to get serious about considering replacing the server before it breaks.  In other words, waiting until the server has problems to begin thinking about replacing it is not a wise strategy (some would argue it isn’t really a strategy at all).  While we can walk into a number of stores and pick up a replacement desktop or laptop; that is not true for servers.  If it crashes and the only option is ordering a new one, you are, at best, going to be down for a week.

 Since 1996, Microsoft has come out with a new Server Operating System approximately every 4 years.  Onsite Logic recommends planning based on server upgrades or replacements on a 4-5 year cycle, but that plan should also include regular maintenance of the investment.  There are a number of ways to redeploy the old server so that it continues to add value in non-business-critical areas.

How to check if an email address exists without sending an email

Returned Email

When an email message bounces back there is always the question: is it us? is it them? is it just a typo?  You may receive a bounce-back email, but trying to decypher can be akin to translating ancient greek.

Here is a quick & simple check to get to the heart of the problem

To check if user entered email mailbox.does.not.exist@reddit.com really exists go through the following in command prompt. Click start and on the run line type in the characters CMD to get to a command prompt (looks like an old DOS screen).

First - Find mail exchanger of reddit.com (after each line press the enter key):

COMMAND:
nslookup
set q=mx
reddit.com
RESPONSE:
reddit.com      MX preference = 10, mail exchanger = mail.reddit.com
mail.reddit.com internet address = 208.96.53.70

Second - Connect to mail server mail.reddit.com

COMMAND:
telnet inbound.onsitelogic.com.netsolmail.net 25
RESPONSE:
220 mail.reddit.com ESMTP Postfix NO UCE NO UEMA  C=US L=CA Unsolicated electronic mail advertisements strictly prohibited, subject to fine under CA law CBPC 17538.45.  This electronic mail service provider’s equipment is located in the State of California.  See http://www.reddit.com/static/inbound-email-policy.html for more information.

COMMAND:
helo hi
RESPONSE:
250 mail.reddit.com

COMMAND:
mail from: <youremail@yourcompany.com>
RESPONSE:
250 2.1.0 Ok

COMMAND:
rcpt to: <mailbox.does.not.exist@reddit.com>
RESPONSE:
550 5.1.1 <mailbox.does.not.exist@reddit.com>: Recipient address rejected: User unknown in local recipient table

COMMAND:
quit
RESPONSE:
221 2.0.0 Bye

NOTES:

1) the 550 response indicates that the email address is not valid and you have caught a valid but wrong email address. This code can be on the server and called on AJAX when user tabs out of the email field.  The entire check will take less than 2 seconds to run and you can make sure that the email is correct.
2) If email was present the server will respond with a 250 instead of 550
3) There are certain servers with a CATCH ALL email and this means all email address are accepted as valid on their servers (RARE but some servers do have this setting).
4) Please do not use this method to continuously to check for availability of gmail / yahoo / msn accounts etc as this may cause your IP to be added to a blacklist.

Microsoft Office Licensing: How many times can I install Office?

A question we often hear is how many computers can I install with my Microsoft Office license.  Here is the official word from the Microsoft website:

How many licenses /installations do Office Product Key Cards allow?

Each Product Key Card allows one user to activate one Office 2010 suite on one preloaded PC.

How many licenses /installations are allowed with the traditional Office discs version?

The number of installations will vary depending on the Office suite purchased. The disc version of Office Home and Student 2010 allows a user to install one copy of the software on up to three PCs in a single household for non-commercial use. (Office Home and Student 2010 cannot be used for any commercial, non-profit or revenue generating activity or by any governmental organization.) The disc version of Office Home and Business 2010 and Office Professional 2010 allows one user to install one copy on one PC and a second copy on his/her portable device such as a laptop.

Can I install an Office Product Key Card on more than one PC?

No. The Office Product Key Card can only be installed on one PC. If you ever need to reinstall Office you can do so on the same PC on which Office was originally installed.

While disc versions may be a little bit more expensive they provide a great deal more flexibility.  You can replace a computer and move the license and it gives you rights to install it on up to two machines at the same time.

Demystifying cloud computing for consumers

USA Today published a good overview of cloud computing, focusing on Amazon, Microsoft and Google.  This article is directed to consumers and does not have a small business perspective, but it does provide a good overview of some of the current buzz.

Google Apps v. Office 365 Feature Showdown: Which Should You Use?

This article from LifeHacker provides a good review of some of the key features and differences between Office 365 and Google Apps.  It does not provide much information focused on Small Business use – more of a high level overview comparison/contrast.

Microsoft Office 365: Installed

Office 365 LogoThe installation of Office 365 is significantly more complicated than installing Google Apps, or for that matter installing Microsoft Office.  The product is a combination of an online account with its various settings and permission requirements and then the installation of Microsoft Lync and the an installation of an Office communicator program and the setup of Outlook.  The instructions provided say to click here and download this, but they leave out about a dozen other steps and numerous questions and log-ons and reboots required.

The key benefit of Office 365 is that it is a full, hosted Microsoft Exchange Server offering priced at $6 per user per month.  For many business with fewer than 10 or even 25 employees, this puts having full Exchange at a very reasonable monthly price.  Compared to Pop3 mail (which is what is included in most webhosting packages), Exchange is a client/server program.  Your email, calendar and task list data resides on the server and various devices such as PC’s, web apps or your cell phone access the data.  The key benefit of this is all devices view the same data, so there isn’t any “out-of-synch” data issues.   Also, because your entire company would have all of its data on the server you can easily share and view calendar information, share contacts, etc. 

Office 365 (P1) has some limitations compared to other hosted Exchange plans offered by other companies.  For instance Office 365 (P1) – which is the Small Business Offering, does not include an Outlook license.  You can either use webmail only or purchase Outlook separately or as part of Microsoft Office.  Most of the other hosted Exchange packages on the market include an Outlook license and software download.

The beta version of Office 365 we are participating in is (P1), the offering for Professionals and Small Businesses.  Like all things Microsoft, there are numerous flavors available, most of them aimed at the Enterprise market.  We’ll discuss more about the flavors and versions in our next post.

Windows 7 is four to five times less vulnerable to malware infections than is Windows XP

Those are the findings of Microsoft’s latest Security Intelligence Report (PDFhttp://i.i.com.com/cnwk.1d/i/tim/2011/05/16/windows-infection-rate.png), which detailed in depth the state of software vulnerabilities, exploits, security breaches, and malware in 2010.

Overall, the study found that infection rates for newer Microsoft operating systems with the latest service packs are consistently lower than those for older OSes, giving Windows 7 and Windows Server 2008 R2 the highest marks for security.

Looking at the number of reported infections per 1,000 computers, Microsoft found that Windows 7 64-bit had the lowest number at 2.5, while the 32-bit version had 3.8.

Windows XP with SP3 came in with 15.9 infections per 1,000, while XP with SP2 had the highest number at 19.3. Breaking down the numbers, Microsoft’s stats mean that Windows 7 is around four to five times more secure than XP.

Windows Vista’s infection rate was considerably lower than that for XP but still turned out to be double that for Windows 7.

Drilling down further, the 64-bit versions of Windows 7 and Windows Vista are less infection-prone than are their 32-bit counterparts, which Microsoft attributes to a couple of factors.

First, the 64-bit versions of both systems may appeal to more tech-savvy users, presumably ones that would better know how to secure their computers. But second, Windows 64-bit offers a feature called Kernel Patch Protection, which protects the Windows kernel from unauthorized changes.

Analyzing server-based operating systems, Windows Server 2003, which offers both 32-bit and 64-bit editions, had 5.8 infections per 1,000. Windows Server 2008 R2, which comes only in a 64-bit flavor, had 3.6 infections.

Security holes in applications versus those in operating systems or Web browsers accounted for most of the vulnerabilities last year, according to Microsoft. However, the total number of holes found in applications fell 22.2 percent from 2009. But exploits that take advantage of Java vulnerabilities rose dramatically in last year’s third quarter, surpassing every other category, the report noted.

Google Cloud Connect and Google Documents

Google Cloud ConnectWe signed up for the beta of Microsoft Office 365 and Google Cloud Connect.  Microsoft, because of demand after the launch of their public beta, is backlogged and a week and a half later we still don’t have the information from Microsoft to begin using the service.

Signing up for Google Documents and Cloud Connect was simple and painless.  Google Documents is integrated into every Google/gMail account.  If you don’t have a Google account you can sign up for free.  Google Documents provides 7.5 GB of free online storage of files.  Interestingly, though, the storage limit does not include documents, spreadsheets, etc., that are created in Google Documents.  As on online, free offering it is clearly not as robust as the Microsoft Office Suite.  But if you just need a basic word processor or spreadsheet functionality, it works. 

We signed in with our gmail account and immediately had access to be able to store and share documents, spreadsheets, etc, stored on Google servers.  We then downloaded Google Cloud Connect which is an add-in to Microsoft Office that makes posting files to the cloud as simple as clicking a button in the toolbar of MS Word or Excel. 

Accessing the files is equally easy.  Simply sign-in with your Google account and there is a drop-down for documents.  You also have the ability from inside Google Documents to upload entire folders to the cloud.

The key benefit of Google Cloud Connect is in sharing and collaboration.  You create a document in MS Word, click the “Sync” button in the Cloud Connect toolbar and your document is stored in the cloud.  You can either log onto the Google website or simply click the link provided in the Cloud Connect toolbar to view the document in the cloud.  There is a share button and you can select or enter email addresses to share the document with, providing them with either view only or view and edit permissions.  The shared document shows up as an email to them and also is immediately in their Google Documents screen.  All changes and revisions are automatically tracked and synchronized.

While incredibly simple, there are some challenges, particularly in fonts/layout and editing.  Google Docs stores the Word document as a Microsoft Word file (.docx file) but it displays it on the screen as a Google Docs file.  As a result, the onscreen view converts the fonts to one of the 19 fonts that comprise Google Documents.  On one of our documents, it also changed the custom margins to standard Google Docs margins.  As a result, our 3 page document displayed as 5 pages and special fonts were converted to Arial.  Furthermore, because this is an onscreen display of a MS Word Document, you cannot edit it like you would a document created in Google Documents.  To edit the uploaded MS Word document you click a button to download and open the document in Microsoft Office on your local computer.    Once the file is downloaded into MS Word, all of the complex layout features such as fonts, margins, tables, etc. are still there and work correctly. 

In summary – First impressions of Google Cloud Connect and Google Documents for Small Businesses:

  • Easy to set up
  • Simple to sign-into
  • Easy to upload
  • Quick
  • Integrates well with MS Office
  • Sharing and Collaboration is a breeze
  • Online viewing and editing is not yet seamless

Cloud Collaboration

 

Everyone is abuzz about “the cloud”.  At its heart, cloud computing is little more than the ability to store and run files and programs that are hosted on someone else’s server – basically what all webhosting is.  The advancement is the advent of new tools, cheap or free storage and more robust applications that make this tried-and-true technology more integrated and more accessible for small businesses.

We will be testing and posting information on two big players, Google and Microsoft, specifically focused on the area of “cloud collaboration.”  Specifically, we believe this is an area of cloud computing that holds the most value for small businesses: the ability to store, exchange and jointly work on documents, spreadsheets, correspondence and calendars in a secure environment on the internet.  We’ll look at how easy it is to setup, use and share various forms of small business documents and communication using the platforms offered by these industry giants.  We’ll also compare costs and functionality.

Why do they make viruses? – Part 1

Computer by Trash CanAs we are cleaning up after a virus infection we are often asked, why does anyone do this? There are a number of different reasons, almost all of them related to money. We’ll explore the first in this post: credit card scams.

A current wave of viruses masquerade themselves as antivirus programs, reporting to you that your computer has been infected. As the pop-ups build and take over your system it provides a link to a website where for $39.99 you can download a program that will remove all of the problems.

Of course, this is all a scam. Your computer is infected, but not by the things it is reporting, it is infected with a Rogue Antivirus virus. One of their primary goals is to get your credit card information to, first, collect the purchase you authorize and then to use your credit card for other uses. Plus, the supposed removal tool is nothing more than more viruses.

Online purchasing from legitimate stores is very safe and secure, however, you should only give your credit card to sites and stores you seek out, not those that come to you asking for it, particularly when it is related to viruses and security.
