There we go;

1) Run regedit- select file- connect network registry- enter the name of the remote computer & select check names.

2) Go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server-- fDenyTSConnections=1

3) Change the fDenyTSConnections value to 0

4) Then your session will be enable.

Enjoy………………..

Thick vs. Virtual Clients

 

I almost laugh at companies that think they can save all kinds of money with a virtualized their desktop. Most companies have little or no business reason for virtualizing their desktops; they just think it has a less TCO than supporting physical desktops. I really try to dig down to why customers are looking or piloting a virtual desktop environment. Is it centralized management of disks? Or is it flexibility of hot-desking with applications and the desktop state still running as a service? Is it for security so that data and applications never leave the data center? Or really, is it a shiny new toy for IS to figure out? I do believe there is a scenario for virtualized desktops. For instance I worked with a large bank who wants to keep their IP local to the US but have offshore developers manage the code and need access to virtual boxes for development and test. The scenarios for a valid virtual desktop is limited and most customers will be swayed away from virtual desktops when they are briefed on better ways to address their pain points of well managed desktop or moving to terminal server architecture. I asked most companies looking at a VDI methodology what kinds of clients were used to access the VDI desktops and without hesitation they said desktop PC’s. So when looping back to their original business case of moving to a VDI approach, they start to understand that virtualization sprawl is not necessarily a good thing because now they need to support double the desktops for their solution instead of using presentation virtualization for their desktops or applications which would meet their business needs and keep their supported desktops to a minimum.

 

Most companies when looking at a virtual desktop are still looking at sustaining the virtual desktop just like they did the physical desktop. So the effect of a virtual desktop is the extraction of the dependencies of the operating system from the hardware. This will give them the ability to dramatically reduce the amount of images they have to maintain and will allow for dynamic provisioning of images. Again, this is not a great argument, with Windows Vista and Windows 7; companies can maintain one image that is hardware independent and can be deployed to virtual or physical computers and have indexes that dictate the applications that get deployed to the target pc. Yes this is physical or virtual however, it starts to lead down the path of where the true focus in this argument should take place, and it’s about the applications not the operating system that companies run on.

 

The customers might see better availability by running the desktop in the data center because in my opinion, the data centers tend to maintain better SLA’s due to tighter change and control procedures but customers can also see improved physical desktop reliability numbers with better change and control procedures applied to the desktop PC’s. Customers looking at virtualizing the desktop have been looking at virtualizing the wrong area in the OSI layer; these customers need to really be looking at virtualizing the applications. Once they see how by virtualizing the applications can provide them greater application compatibility, agility and dynamic deployment of applications on thin-trim-thick clients they understand that they are looking in the wrong area of virtualization.

 

Total Cost of Ownership (TCO) and Desktop Virtualization. VMWare has a TCO tool that produces a very nice Excel spreadsheet that shows the TCO cost savings using VMWare for virtual desktops. This tool uses a a model of a typically managed desktop and compares it to a well managed virtual environment. It is interesting if you add the well managed desktop numbers into the spreadsheet, you get an almost identical cost for a well managed desk and depending on the workload, and a well managed thick desktop is cheaper than a VDI Light and Heavy Workload. It really comes down to how many clients can be on a single core. VMWare says that they can handle 50 users per core but customers are experiencing about 6-8 users per core where as a 64 bit terminal server documentation says it can handle about 150 user per core but in reality customers run approximately 100 users per core.

Thick vs. Thin Clients

 

First of all, thin client computers do not have a lower TCO and are not Greener than Windows laptops.

Companies can realize some cost savings in moving from thick to thin, in analyst studies say that the cost savings is around 8%. Let’s look at what 8% savings actually costs the business that implement a thin client architecture; poor video streaming, no audio upstream, limited peripherals, limited mobility, sporadic performance of shared computing architecture. Regarding the acquisition cost, the thin clients cost around ~$300US where a bottom of the line Windows PC cost ~$500. Also, many customers don’t like to discuss soft cost savings, when you remove the soft cost from the equation; a well managed rich desktop has a lower TCO than thin client architecture. When competing in a TCO discussion, the greatest savings a customer can realize is not moving platforms or architectures, but moving across an IT maturity model of best practices. 

Some competitors talk about how thin is more green than thick. This is also a lie. It’s true that the SunRay client only uses 4W of power, but they also use middleware servers that host about 40 – 50 clients per server. In a 1,000 user environment, the middleware servers pull about 18,000W of power. Most customers redirect the SunRay servers back to Windows Terminal server architecture anyway. So if the customer just used a Wyse devise which pulls about 4.5W of power going directly to a Windows Terminal server architecture saves 18,000W of power.  Windows GPO settings will only cost a company about $12 per PC (excluding monitor.)

TCS partners Microsoft for setting up virtualisation centre - Business News - News - MSN India
Mumbai: IT outsourcing firm Tata Consultancy Services has entered into an alliance with Microsoft India to launch a virtualisation Center of Excellence (CoE) in Chennai.

The Microsoft-TCS virtualisation CoE is a joint initiative by the companies to accelerate the adoption of virtualisation technology in India, TCS said in a filing to the Bombay Stock Exchange today.

"Virtualisation is one of the most disruptive technologies in the world today. Through our partnership...We will address this crucial market need and help customers lend the benefits of virtualisation technology," Microsoft India Managing Director Rajan Anandan said.

Virtualisation is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. This helps companies in cutting costs and optimising resources.

"We are always looking to enhance the services we provide to our customers. The Microsoft-TCS virtualisation CoE is an initiative aimed at enabling our customers rapidly realise the advantages of this technology," TCS Infrastructure Services, Vice President & Global Head PR Krishnan said.
