How To Create A Service In Windows 2008 R2

In this article you will learn the basics of managed service accounts in Windows Server 2008 R2.

Here'southward the situation: Y'all are called into consult for a client, and in examining their Information technology infrastructure you notice no organization as to how service accounts are deployed. For instance, some line-of-business (LOB) applications are using the domain Administrator equally their service account identity, while others use the Local Service or Network Service identity.

Recently, the customer began associating application services with defended domain user service accounts. All the same, because domain password policy forces countersign changes every 60 days, the manual reassignment of service business relationship passwords created organizational headaches for the IT back up staff.

How can you resolve this mess of a real-globe situation?

Introducing Managed Service Accounts ^

In Windows Server 2008 R2, nosotros finally have a solution to the problem of reconciling service accounts with Agile Directory password policy: the Managed Service Account, or MSA.

When yous ascertain an MSA, you leave the account's countersign to Windows. Thus, MSAs interoperate only fine with your organizational password policies. When it comes time to change the MSA countersign, Windows takes intendance of that for you lot, automatically generating a password that meets any complexity requirements you may have mandated.

As wonderful and user-friendly as MSAs are (and they are, trust me), nosotros need to always proceed in mind the IT security principle of to the lowest degree privilege. In other words, we must be careful not to assign permissions, either explicitly or implicitly, to the MSA account that are beyond the required admission scope of that business relationship.

Creating Managed Service Accounts ^

We apply Windows PowerShell ii.0 to create and manage MSAs. From an elevated command prompt, type powershell to enter the Windows PowerShell surround.

Next, type import-module activedirectory to load the Active Directory PowerShell cmdlet library.

We use the new-adserviceaccount cmdlet to define a new MSA. For example, the post-obit argument creates an MSA named testmsa and enables the account for employ:

PS>new-adserviceaccount –Name testmsa –Enabled $truthful

To verify that the MSA has been created and is "set for action," so to speak, run the get-adserviceaccount cmdlet. Sample output from this cmdlet is shown in Figure ane:

The get-adserviceaccount cmdlet

NOTE: Windows appends a dollar sign ($) to the MSA account name. Therefore, an MSA named testmsa appears in the computer's SAM or Active Directory as testmsa$.

We tin can likewise fetch MSA properties from Active Directory Users and Computers. Open up the tool, click View > Avant-garde Features to display advanced features, and expand the Managed Service Accounts container. This is shown in Figure two:

Using Managed Service Accounts ^

Once they are defined, we tin associate MSAs with applications and services by using any of the traditional methods with which you are familiar.

For instance, you can open the Service Command Managing director, double-click a service, and navigate to the Log On tab to scan Active Directory for an MSA. This procedure is shown in Figure 3:

Assigning an MSA to a service

Notation: Exist sure to leave the Password and Ostend countersign fields empty. Recall, we are delegating account countersign management to Windows.

Once y'all apply the change, you will see a Services message box informing you that the designated MSA has been granted the Log On as a Service user right. This message box is shown in Effigy 4:

Taking the next step ^

From Windows PowerShell, yous tin can issue the statement get-command –noun *adserv* to retrieve a list of all MSA-related cmdlets.

You tin then run help <cmdname> to obtain online help concerning syntax and usage concerning that specific cmdlet.

Conclusion ^

If you lot are similar me, and then yous notice that the Managed Service Account capability of Windows Server 2008 R2 is an administrative godsend. Windows PowerShell is increasingly becoming a "must have" skill fix for Windows administrators; delight see my 4sysops blog posts on the subject area if you'd like a full general introduction to Windows PowerShell.
