Dropbox – a cloud storage

Dropbox is a file hosting service operated by Dropbox, Inc that offers cloud storage, file synchronization, and client software.Dropbox provides client software for Microsoft Windows, Mac OS X, Linux, Android, iOS, BlackBerry OS and web browsers, as well as unofficial ports to Symbian, Windows Phone, and MeeGo.Both the Dropbox server and desktop client software are primarily written in Python.he Dropbox client enables users to drop any file into a designated folder that is then synchronized with Dropbox’s Internet service and to any other of the user’s computers and devices with the Dropbox client. Users may also upload files manually through a web browser.Dropbox client supports synchronization and sharing along with personal storage. It supports revision history, so files deleted from the Dropbox folder may be recovered from any of the synced computers.Dropbox supports multi-user version control, enabling several users to edit and re-post files without overwriting versions.The version history is by default kept for 30 days, with an unlimited version called “Pack-Rat” available for purchase.Dropbox uses Amazon’s S3 storage system to store the files.It also uses SSL transfers for synchronization and stores the data via AES-256 encryption, though this is done with Dropbox’s own encryption keys, and not the users.

Check RD License information

To check license information please open RD Licensing Manager (licmgr.exe). If you do not have a RD Licensing server then you need to install the RD Licensing Role Service using Server Manager and then use RD Licensing Manager to Activate it and install your purchased RDS CALs.

For Per Device RDS CALs you can see which devices have been issued licenses, when they expire, installed licenses, etc. For Per User RDS CALs you must right-click on the server name and choose Create Report–Per User CAL Usage, create the report, in the left pane select the server name and then Reports, then finally right-click on the Report you just created in the right pane and choose Save As to save it as a .csv file. You can open the csv file in Notepad to view issued Per User CALs, total, expiration dates, etc.

Please verify that you have Specified your RD Licensing server in RD Session Host Configuration (tsconfig.msc) and that you have set your Licensing mode to match the type of purchased RDS CALs that you have.

Chrome VS IE

Many of us have asked the question ,which is a good browser?
Answering to this questian is little confuse because it depend on its own OS (safari will good performance in apple system).Each browser has strengths and weaknesses.In 2008 google come with chrome. Now 75 crore users are using it.Chrome is the top browser and 36 percent of the global browser market share compairing 31 percent IE and firefox 21 Percent.

There are some blogs compairing difeerent browsers.

What is SVCHOST?

You will notice that most ports are held by one of the many instances of svchost.exe. Most Windows services are not full executables, merely DLLs. These DLLs must be loaded by a host executable like SVCHOST. This saves system resources at the expense of security. To determine which services are running under a specific instance of SVCHOST, open a command prompt and enter:

tasklist /svc

Svchost usually runs as one of three special users: SYSTEM, LOCAL SERVICE, or NETWORK SERVICE. Unfortunately, even the system administrator does not have sufficient rights to kill SVCHOST when it runs as one of these three users.

Active Directory Logical and Physical Components

Active directory introduced in windows 2000 operating system(little old stuff).
Active Directory can be considered to have both a logical and physical structure, and there is no correlation between the two. The logical parts of Active Directory include forests, trees, domains, OUs and global catalogs. Each element of the logical structure of Active Directory is defined below:

Domain – a domain in Windows 2000 is very similar to a domain is Windows NT. It is still a logical group of users and computers that share the characteristics of centralized security and administration. A domain is still a boundary for security – this means that an administrator of a domain is an administrator for only that domain, and no others, by default. A domain is also a boundary for replication – all domain controllers that are part of the same domain must replicate with one another. Domains in the same forest automatically have trust relationships configured.

Tree – a tree is a collection of Active Directory domains that share a contiguous namespace. In this configuration, domains fall into a parent-child relationship, which the child domain taking on the name of the parent.

Forest – a forest is the largest unit in Active Directory and is a collection of trees that share a common Schema, the definition of objects that can be created. In a forest all trees are connected by transitive two-way trust relationships, thus allowing users in any tree access to resources in another for which they have been given appropriate permissions and rights. By default the first domain created in a forest is referred to as the root domain. Amongst other things, this is where the Schema is stored by default.
There are two types of active directory forest :-
I) Single Forest
2) Multiple forest

Organizational Unit – An organizational unit (OU) is a container object that helps to organize objects for the purpose of administration or group policy application. An OU exists within a domain and can only contain objects from that domain. OU can be nested, which allows for more flexibility in terms of administration. Different methods for designing OU structures exist including according to administration (most common), geography, or organizational structure. One popular use of OUs is to delegate administrative authority – this allows you to give a user a degree of administrative control over just the OU, and not the entire domain.

Global Catalogs – Global Catalogs are listings of every object that exists within an Active Directory forest. By default, a domain controller only contains information about objects in that domain. A Global Catalog server is a domain controller that contains information about every object (though not every attribute for each) stored in the entire forest. This facilitates and speeds up the search for information in Active Directory. By default only the first domain controller created in a forest has a copy of the global catalog – others much be designated manually.

The physical structure of Active Directory helps to manage the communication between servers with respect to the directory. The two physical elements of Active Directory are domain controllers and sites. Each is described below.

Domain Controllers – domain controllers are Windows 2000 Server-based systems that store the Active Directory database. Every Windows 2000 domain controller has a writable copy of the directory. This is different that in NT 4, where only the PDC had this capability. Domain controllers in the same domain contain replicas of the directory that must be synchronized periodically.

Site – a site is a concept that did not exist in an NT directory service structure. In Active Directory, sites are groups of IP subnets that are connected at high speed. Although the definition of ‘high speed’ is open, it is generally considered to be subnets that are connected at LAN speeds (say 10 Mb) or higher. The purpose of defining sites in Active Directory is to control network traffic relating to directory synchronization, as well as to help ensure that users connect to local resources. For example, domain controllers located in the same site replicate with one another on a 5-minute change notification interval similar to in NT 4. However, replication between domain controllers in different sites can be scheduled according to your needs. This allows a much greater degree of flexibility that in NT 4. For example, you could set things up such that replication between sites could only happen between midnight and 6am – thus ensuring that replication traffic would not interfere with normal data transfer during business hours. Sites also help ensure that users avoid accessing resources over the WAN by having client systems access servers (such as domain controllers) that are in the same physical site first.

what is wrong with the installation of Windows patches MSRT taking time

The Microsoft Malicious Software Removal Tool is an anti-malware utility

that checks computers running Windows 8, Windows 7, Windows Vista, Windows

XP, Windows 2000, Windows Server 2012, Windows Server 2008, and Windows

Server 2003 for infections by specific, prevalent malicious software—

including Blaster, Sasser, and Mydoom—and helps remove malware and any

other infections found.

When the detection and malware removal process is complete, the tool

displays a report describing the outcome, including which, if any, malware

was detected and removed

how to run manuaaly
You can run MSRT manually at any time. In Windows XP, use Start -> Run ->

mrt.exe. You can even get away with just “mrt” in the Run box. In Vista,

type “mrt” into the search box (yes, it’s “mrt” not “msrt”). It seems to

do a lot of processing before displaying the initial window, expect a

delay of 5 to 10 seconds.

full scan :can take a few hours and may keep the processor busy.It scan

fixed and removable drives except mapped network drives.
