Annoying “This page contains both secure and nonsecure items” warning and how to get rid off it?

January 20, 2011 Leave a comment

Warning

Just a quick and short post about this warning and what are possible solutions to get rid of it. So the warning happens sometimes when you setup SSL for example on Windows Sharepoint Services (WSS) site. After that, anytime you open the site,  or navigate back and forth this warning pop-out.

Cause

This happens because some of links on your site point to http instead to https. So if you have some links, pictures or something else that is having http in link you have that warning. Also, what I personally experienced is that this error happened because of using specific Windows Sharepoint Services theme (Basic theme).

How to solve the problem?

Change Sharepoint theme. Go to Site actions> Site settings > Look and feel > Site theme  and change theme to default.

Check if anything (links, pics…) on your site is still using http links. Change those to https or start using relative path instead of absolute. Absolute link is –> http://example.com/img.jpg  and relative (in Sharepoint)  is –> _layouts/images/  or //http://www.example.com/img.jpg

Change browser settings:

          1. Tools > Internet options
          2. Security tab > Custom level
          3. Scroll down to “Display mixed content” and select Enable
          4. Click Yes on  Security warning pop-up
              Hope that solves your problem.

    Microsoft Assessment and Planning Toolkit (MAP) 5.5 RTM / Final Release

    January 17, 2011 1 comment

    Microsoft Assesment and Planning toolkit

    Microsoft Assessment and Planning Toolkit  5.5 is available and can be downloaded from Microsoft site. It is really great, and free tool from Microsoft.

    It is a powerful inventory, assessment and reporting tool that can securely assess IT environments for various platform migrations and virtualization without the use of any software agents.

    Ok, for which scenarios can this tool be useful?

    In many, many, many scenarios. Let’s see:

    Agentless inventory -  tool collects system resources and device information  from computers in your environment. Tool doesn’t require installation of any kind of agent on computers. MAP uses technologies already available such as WMI, Remote Registry Service, Active Directory Domain Services and Computer Browser service.

    Compatibility and readiness analysis – it performs analysis of hardware and device compatibility for Windows 7,  Windows Server 2008 R2, SQL Server 2008 R2 and Microsoft Office 2010. It also provides database and web application readiness for Windows Azure and SQL Azure.

    Virtualization consolidation recommendation – MAP analyses servers which you plan to virtualize (P2V) and compare those results with results it collected from potential Hyper-V hosts. Based on those comparison and analysis it identifies right candidates for virtualization and suggests placing of virtual machines on physical servers.

    And what’s new in version 5.5?

    • Windows Azure platform assessment for easier migration to the cloud
    • Heterogeneous database discovery for accelerated migration to SQL Server
    • Microsoft Internet Explorer migration assessment for migration to Windows 7 compatible versions
    • Enhanced server consolidation capabilities help save time and effort when creating virtualization assessments and proposals

    To conclude MAP is free, very useful tool which has many great functions, and just some of them were described here. For more information see Technet.

    Internet Explorer 6 on Windows 7 (IE6 + Windows 7)

    January 13, 2011 1 comment

     

    Internet Explorer 6 with Windows 7

    Yes Internet Explorer 6 is still used worldwide!

    Actually  I was writing about similar topic (IE6 on Windows 7 using XP mode) once before because a lot of enterprises today are running their line-of-business (LOB) web applications on Internet Explorer 6. In other words those applications can’t run or they do not behave normally on Internet Explorer 8. Also we all know that migrating on Windows 7 causes that you can’t use Internet Explorer 6 anymore. Of course you can use XP mode or Microsoft Enterprise Desktop Virtualization (MED-V), but what if you don’t have the possibility to use virtualization technologies. Anyway obviously, compatibility issues of line of business applications with new Internet Explorer 8 (or 9 when it RTM’s) is a major showstopper for many companies today. 

    According to Gartner Research, IE6 compatibility problems will cause 1-in-5 organizations to take longer than expected or spend more than they budgeted for their Windows 7 migration projects. Problem is that approximately 40 percent of the Web applications used by companies still running IE6 won’t work on IE8 – the browser bundled with Windows 7

    Ok so what’s the solution?

    Luckily there is one great add-on to IE 8 which allows you to run complete IE6 engine inside IE8 tab. In that way you can easily without any fear migrate to Windows 7, migrate to new Internet Explorer and still use your older LOB web applications. Company that developed that product is called Browsium,  and product is called UniBrows. As they say Unibrows is:

     

    an innovative new product that removes a key impediment to enterprise upgrades by enabling millions of IE6-based line-of-business web applications to run unmodified on Windows 7 or on IE8 on Windows XP (and IE9 when it is released). UniBrows is an IE add-on that runs the complete IE6 rendering engine and web-application platform inside an IE8 tab. UniBrows is not virtualization, does not run a separate instance of IE, and does not change the default browser or normal browsing behavior.  By installing UniBrows on client PCs running Windows 7 or Windows XP with IE8, organizations can upgrade their OS and browser platforms organization-wide immediately and then rewrite or replace legacy applications on an independent schedule.

    So key characteristics to remember here are:

    • UniBrows allows you to run your IE6 LOB web applications normally on IE8 and IE9  when it will be released.
    • UniBrows is simple to deploy
    • It does not require any changing in applications or in your current IE8 browser.
    • It can be configured (with Group Policy) to automatically know which web sites to           open with UniBrows add-on.

    What is Private Cloud a.k.a Private Cloud for beginners

    December 21, 2010 Leave a comment

    What is private cloud

    These days you can find tons of information on Internet regarding Private Cloud. What is it, how it can be used, how can you benefit from it – all those scenarios and hundreds more are explained everywhere. My intention is not to detaily describe Private Cloud or Cloud Computing. My intention is to describe private cloud as easy as it gets, preferably with „real“ world comparison. Also, keep in mind that there are a few Private Cloud „offerings“, and that herby I’m talking about IAAS – Infrastructure as a Service.

    Ok first what does that (IAAS) mean? Let’s analyze those two words; infrastructure and service. In IT world infrastructure is actually combination of following resources: memory, CPU, storage, networking,operating system etc.. Ok now we have also a service which can be defined as „ providing something to someone“. So it’s clear that IAAS is actually  a model where someone provides infrastructure services to someone else. Keyword here is someone, because if this someone is public company providing services to some other company – then this can be „normal Public Cloud“. On the other hand if for example one company provides infrastructure as a service to departments in that same company – then that can be called „Private Cloud“.

    If we compare that to some plastic real world example it could be something like Rent a Car model. Smiješak So, in the world there are a lot of Rent a Car companies in which you decide to go if you’d like some services [a Car]. You also decide that this particular car needs to have some amount of horse power, CCM, needs to have 4WD etc. Then you pay for all that and you get that car as a service, exactly as you wanted, and fast too. That could be compared to Public Cloud because some public company „host“ services (e.g. car) for you or your company. On the other hand, your company can have maybe dozen cars available for you and for other employees to use. You then explain  why you need a car, when you need it and what kind of car you need. Your company provides you with that car so in that case you’d also get car as a service, but now this service is private.

    Ok, now after that comparison, let’s see how can that Private IAAS Cloud be achieved in IT world. Of course, here virtualization (among other stuff) comes in place. Why? Well because of some main characteristics of cloud (whether public or private) :

    • Scalability
    • Automatism
    • Elasticity

    In other words, when you or your department need Windows Server 2008 R2 with 4 GB of RAM, 2 CPU’s, 100 GB disk and Active Directory Services role installed, you need that fast and without much intervention (you don’t want to configure everything by yourself). In other other words, if you’d need that same Windows Server 2008 R2, and if it can only be served to you in a physical manner (a.k.a real metal physical server), you would  probably not get it in that same automatic, fast and „elastic“ way.

    So yeah, that’s about it in high level and without mentioning actual technologies used for building private cloud solution. My way of demystified Private Cloud and IAAS.

     

    P.S. In some of my future post I will cover actual Microsoft Private Cloud Offerings and technologies included – so stay tuned.

        For past couple of months I didn’t write any blog post. And why is that, some of you might ask. Well, I was very busy with my business and personal life. I was involved in many many projects so I really didn’t have much time to write. Anyway now I’m back with plan to write more often and of course with more quality. Also, from now on I will not write only on Microsoft Virtualization but also on some other Microsoft technologies which are in my area of expertise. So stay tuned, and I will try to offer you some quality and perhaps entertaining posts.
