In Systems Management Server (SMS) 2.0 Service Pack 2 (SP2) and later, administrators can set up the SMS Service account as a non-domain administrator in both Microsoft Windows NT 4.0-based and Microsoft Windows 2000-based domains. For details about using this configuration, including important warnings, read Chapter 4 - Creating Your SMS Security Strategy of the Systems Management Server 2.0 Administrator's Guide.
By default, SMS Setup requires the Service account to be a domain administrator and does not allow the installation to finish if you are using a non-domain administrator account. To install SMS by using a non-domain administrator Service account:
Create the SMS Service account.
Ensure that the SMS Service account is a local administrator of all potential site systems (site servers, Client Access Points, Logon Points, or Distribution Points). Beginning in SMS 2.0 Service Pack 5 (SP5), it is possible to administer logon points under the context of a normal user account.

Run Setup.exe with the /nodomainadmin switch (for example, setup.exe /nodomainadmin).
Setup.exe is located in the Smssetup\Bin\I386 folder on the CD-ROM. If you attempt to change the SMS Service Account account or password through SMS Setup (a site reset), you may receive the following error message:
Setup has detected that the service account Domain\Serviceacct is not in the Domain Admins group in domain Domain, do you want to add it to the Domain Admins group.
To work around this issue, change the SMS Service account user name and password in the SMS Administrator tool:
Locate the site whose SMS Service account you want to change.
Right-click the site, and then click Properties.
In the Site Properties dialog box, click the Accounts tab, and then click Set.
Type the SMS Service account information again.
Or, you can initiate a site reset by starting Setup.exe with the /nodomainadmin switch from a local drive or CD-ROM.
