In Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2, IIS ran under a standard user account. This had the potential to cause issues: if that password expired you could lose your Web Services, an issue that was often difficult to diagnose. To help avoid the issue of expiring passwords, Skype for Business Server enables you to create a computer account (for a computer that doesn't actually exist) that can serve as the authentication principal for all the computers in a site that are running IIS. Because these accounts use the Kerberos authentication protocol, the accounts are referred to as Kerberos accounts and the new authentication process is known as Kerberos web authentication. This enables you to manage all your IIS servers by using a single account.

To run your servers under this new authentication principal, you must first create a computer account by using the New-CsKerberosAccount cmdlet; this account is then assigned to one or more sites. After the assignment has been made, the association between the account and the Skype for Business Server site is enabled by running the Enable-CsTopology cmdlet. Among other things, this creates the required service principal name (SPN) in Active Directory Domain Services. SPNs provide a way for client applications to locate a particular service.

After a new association has been made, the Set-CsKerberosAccountPassword cmdlet provides a way to modify the password assigned to the account and, equally important, update the password on every computer that uses the specified Kerberos test account for Kerberos web authentication.

In addition, the cmdlet can also use the ToComputer and FromComputer parameters to copy this configuration information from one computer to another.

Set-CsKerberosAccountPassword -UserAccount "litwareinc\kerberostest"

The command shown in Example 1 sets the password for the Kerberos account litwareinc\kerberostest.

Set-CsKerberosAccountPassword -FromComputer "atl-cs-001.litwareinc.com" -ToComputer "dublin-cs-001.litwareinc.com"

In Example 2, the Kerberos account password is copied from the computer atl-cs-001.litwareinc.com to the computer dublin-cs-001.litwareinc.com.

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutBuffer, -OutVariable, -PipelineVariable, -ProgressAction, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.

The Set-CsKerberosAccountPassword cmdlet does not return any objects or values. Instead, the cmdlet modifies existing instances of the Microsoft.Rtc.Management.WritableConfig.Settings.KerberosAccount.KerberosAccount object.
