SBS 2000: "You Must Be Logged in as the Built-in Administrator" Error Message During Upgrade (303440)

RESOLUTION

1. Verify that you are logged on as Administrator. You must be logged on as the built-in domain Administrator for SBS 2000 Setup to complete successfully. If the Administrator account has been renamed, you must rename the account back to Administrator (with a capital 'A'). Once the upgrade has completed, you can safely rename the Administrator account. If you have renamed the Administrator account, rename the account:
   1. Click Start, point to Programs, and then click Administrative Tools (Common).
   2. Click User Manager for Domains, and then click the Administrator account.
   3. Right-click Administrator, and then click Rename.
   4. Rename the account to Administrator (with an uppercase "A").
2. Verify that the Administrator account is actually the built-in Administrator account and not a user account that has been named Administrator and been added to the Domain Administrators and Administrators group. To do so, view the Administrator account properties:
   1. Click Start, point to Programs, and then click Administrative Tools (Common).
   2. Click User Manager for Domains.
   3. Double-click the Administrator account.
   4. The built-in Administrator account is the account that was created as "Administrator" when your server was originally installed. If you have since renamed the Administrator account to something else, you need to name it back to "Administrator." If you are not sure which account really is the built-in Administrator account, you can determine which one it is by trying to disable the account in User Manager for Domains. When you attempt to disable the original built-in Administrator account, you will receive the following error message:
      The following error occurred changing the properties of the user [user name]:
      
      Cannot perform this operation on built-in accounts.
      When you receive the preceding error message, you will have correctly identified the built-in Administrator account.
3. Verify that the Administrator account is a member of the following groups:
   • Domain Administrators
   • Administrators
   • Domain Users
4. Restart the SBS 2000 upgrade, and then test to determine if the issue is resolved. If it is, skip the remaining steps. If it is not, continue to the next step.
5. Change the Administrator's password to a null (blank) password:
   1. Start the SBS 4.5 console, click the Tasks tab, and then click Manage Users.
   2. On the left side of the console, click the Administrator account, and then click change password.
   3. When the Change Password Wizard starts, click Next, click I want to specify the password for Administrator, and then click Next.
   4. Leave the Password and Confirm Password boxes blank. Click Administrator is not allowed to change the password, and then click Next.
   5. Click Finish to set the password.
      
      WARNING: Do not use User Manager for Domains to change the Administrator's password. Use of the Change Password Wizard updates the password in several different locations, including service account settings and the Exchange Service Account password. If you have already reset the Administrator's password, or you are unable to change the password by using the Change Password Wizard, you must use the procedure that is described in the following Microsoft Knowledge Base Article:

      After the upgrade to SBS 2000 is complete, be sure to assign the Administrator account a strong password. Test to determine if the issue is resolved. If it is, skip the remaining steps. If it is not, continue to the next step.
6. Modify the Setup.sdb file:
   1. Copy the \Bkoffice folder from the root of the SBS 2000 CD-ROM disk 1 to a partition on the SBS-based computer.
   2. Remove the Read Only attribute from the Setup.sdb file in the Bkoffice folder on your hard disk. The Setup.sdb file is located in the \Bkoffice\i386 folder.
   3. Place a semi-colon (;) in front of the following line in the Suite Requirements section of the Setup.sdb file, for example:

      ;bosreqs.dll, GFN_CID AdminCheck

   4. Double-click the Setup.exe file in the copied folder to start Setup.
