I don't really understand why they would refuse unless it is a shared IP, but if they really do then you can look at the option the article gives you. I doubt there's a DNS server admin out there that doesn't have a copy.

Mastering PowerShell's scripting logic, understanding how it's object and variable engine works and smartly deploying it on your network will have you wondering why you've gone so long without using it.

This guide will walk you through the basics of PowerShell, which is easy for entry-level IT professionals to learn, especially if you're already familiar with Window's Command Prompt. We'll cover how to use the basic tools and commands, how to manipulate files and folders, understanding objects, using variables and managing remote servers. As with most things in life, taking the time to learn and fully understand the basics will go a long way toward avoiding headaches and will help you grasp more advanced concepts as you dive deeper into the world of PowerShell commands.

The three concepts introduced in this section are fundamental to understanding the key concepts that form the basis of PowerShell. Newer versions of PowerShell introduce new features and "cmdlets" Microsoft's term for PowerShell commands — pronounced "command-lets" and are installed using the corresponding version of the Windows Management Framework WMF.

In some cases, several new features are dependent on the operating system in addition to the WMF version. The PowerShell console appears like the traditional command line, but with the full weight of PowerShell behind it.

Variable names, loops, tab completion, and piping are all available from the PowerShell console. For more in-depth use such as script building the PowerShell ISE offers tab completion, code highlighting, and Microsoft's Intellisense code completion capability to assist you in creating and testing your PowerShell code. The basis of PowerShell commands are cmdlets. Microsoft made several design strategies when designing PowerShell cmdlets.

First is the ability to easily infer cmdlet names, or at the very least make them easy to discover. PowerShell commands, or cmdlets, are also designed to be easy to use with standardized syntax, making them easy to use interactively from the command line or to create powerful scripts.

The verb portion of the cmdlet name indicates the action to be performed on the noun. Typically, cmdlets used to request information use the Get verb, as is the case with Get-Process or Get-Content. Commands used to modify something will usually begin with the verb Set, while those adding a new entity to something often begin with Add or New. In many cases these verb-noun combinations can be guessed or predicted because of the standard naming convention.

Standardized cmdlet naming isn't the only aspect of PowerShell designed to improve command line usability. Parameters commonly used throughout PowerShell also use standard names.

One example of this is the -ComputerName parameter, which allows a cmdlet to be executed against one or more remote computers. Likewise, -Credential is used to provide a credential object, containing a user's login credentials, to run the command as a specific user. When using PowerShell via the console, aliases can be used for both cmdlets and parameters to conserve keystrokes and shorten the overall length of a command an advantage which should not be overlooked when piping commands together.

Cmdlet aliases do not always use a standard naming convention, however they do often mirror traditional command line utilities. Parameter aliases can work in two ways: Regardless of your niche in the IT industry, chances are some part of your daily grind involves managing files and folders in some way. Whether it's moving folders to another location on a server, archiving log files, or looking for large files; almost every system administrator spends part of their day managing files and folders.

In cases where repetitive tasks are being repeated on multiple files, or the same set of tasks are run repeatedly, automation through PowerShell can be a real time saver. For those new to the game, dir would list the files and folders contained within the specified directory. Often when working with files, all we need to know is whether a file exists or a folder path is valid.

As you would expect, PowerShell is fully capable of performing standard file operations on numerous objects in a single pass. It's been said of scripts that they enable people to do stupid things extremely quickly. This allows you to require user interaction prior to the operation actually taking place. Often this is preferable to simply assuming everything is ready to go file backups complete, replication disabled, etc. The key to PowerShell, in addition to the standardized naming and other features, which make it intuitive, is that many of the cmdlets are object based.

By working with objects, PowerShell allows you to easily make changes to multiple items with a single line of code, make changes to a specific subset of items within thousands, or use these objects to collect data or perform actions on other related objects.

Objects, for those not familiar with the terminology, refers to items which contain multiple attributes or properties; such as strings of characters, lists of information, and numerical values.

Not only will Get-Member show you the properties of an object and the data types they contain, but it will provide you with the object type as well, which can in turn be used to find other cmdlets, which can accept an object type. PowerShell allows you to leverage cmdlets and objects through a technique known as piping. Using the pipe character , you can quickly and easily select objects and then perform an action on them. Often cmdlets with the same noun will be used when piping, but the technique is not limited to cmdlets with the same noun.

Using the object type returned using Get-Member, you can find other cmdlets which can be used to receive a piped command. There is a whole list of cmdlets in PowerShell used for performing heavy lifting with objects, specifically those with the Object noun.

Many of these cmdlets are among the most commonly used cmdlets, while others are used for more specialized tasks. The syntax used with Where-Object is worth noting and applies to some of the other object cmdlets as well.

The squiggly brackets are used to delineate a code block in PowerShell, and in this case indicate the condition being applied to the object in the pipeline. PowerShell comparison operators use hyphenated formatting, so -eq equals is used to find an exact match with the word "Stopped" in our example. For interactive use within the PowerShell console, using aliases can save time and effort. The Where-Object cmdlet makes use of the question mark? From a syntax perspective ForEach-Object is very similar to Where-Object, with both the script block and automatic variables being used with both cmdlets.

Where ForEach-Object excels is being able to perform tasks against each object instance that are too complex for simple piping. FullName to list the file security for the list of files. Also, the PowerShell 3. While filtering an object or performing an action on instances of an object are both common tasks, it's a good idea to avoid both Where-Object and ForEach-Object when possible.

Likewise, ForEach-Object performs an individual action on each instance of the piped object. When possible, objects should be piped directly to cmdlets which can perform the required action on the entire object, without having to enumerate each item within the object. System administrators make decisions daily regarding what maintenance tasks to perform on servers based on numerous criteria.

Automating repetitive administrative tasks with PowerShell frequently involves using logic to replicate this decision-making process. Several techniques can be used to achieve the desired results using comparisons, filters, and conditional logic. You won't get far in creating PowerShell scripts without performing conditional logic, which begins with comparing values. The ability to check if a user exists, if a file has been created, or if one computer is able to connect to another all require a comparison to a value.

The one big gotcha in PowerShell has to do with syntax: Several comparison operators are most commonly used with numerical values, although they have their place when working with dates or version numbers and other variable types as well. The following table contains the comparison operators most commonly used to compare numbers.

In cases where more than one condition must be met, parenthetical statements can be used in order to manage groups of conditions. The following example can be used to select processes related to various web browsers:. Many common PowerShell cmdlets return a long list of values which are of little use as a whole. The following example lists files in the current user's profile which have the archive bit set:.

PowerShell 4 allows you to use Where-Object using aliases such as? This example is functionally identical to the one above:. By setting first the criteria to be met, and then the action to be taken, IT pros can automate complex administrative actions.

The following example shows a simple if statement that tests for internet connectivity:. This differs from multiple if statements in that only the first condition met will be used. Else statements are placed at the end of an if statement to perform an action if none of the previous conditions are met.

Switch statements begin with the switch keyword followed by the expression to be evaluated. Each of these matches is followed by a scriptblock, which defines the actions to be taken when the condition is met. Using wildcards with switch statements gives you a more efficient method of performing conditional actions.

PowerShell is intuitive enough that entry-level or mid-tier admins can begin to learn the language, use cmdlets from the console, and even begin to write reasonably simple scripts. Once your PowerShell scripts begin to become more complex, you'll need to start working with aspects of PowerShell that will take you back to the programming classes you took in college. Variables in particular are essential for scripting, because they enable you to pass information between parts of your script.

You will remove your registrar's current name servers and replace them with the HostGator name servers from your welcome email. HostGator uses both LaunchPad and eNom as the registrar for domains. Both are managed through HostGator's domain control panel. These instructions are up-to-date as of the day we posted them however some registrars frequently change their website and may use different terms such as referring to your name servers as nameservers , so expect variations from the instructions provided.

For some advanced users, it may be desirable to use different name servers. This requires more maintenance, since it is not automatically updated like HostGator name servers are. For more details on how to do this, read the following article:. We cannot provide direct support in modifying the DNS records at your registrar.
