XADM: Exchange 2000 Setup Fails and Security Vulnerability (278523)

RESOLUTION

Before You Run Setup

To minimize the security risk that this account represents, manually create an account that uses the same name, EUSER_EXSTOREEVENT, before you run Setup, and give the account a password that meets the password complexity requirements of your company. During installation, Setup will detect that this account already exists and will not attempt to create it or change the password.

When You Install Exchange 2000 on a Member Server

Create the account as a disabled local user account. The following steps outline how to create an account in the local account database:

1. Start the Computer Management MMC snap-in by clicking Start, pointing to Programs, pointing to Administrative Tools, and then clicking Computer Management on the member server that Exchange 2000 will be installed on.
2. Expand the Local Users and Groups container, and then click the Users container.
3. On the Action menu, click New User.
4. In the New User dialog box, fill in the following information:

   Username: EUSER_EXSTOREEVENT
   Password: A password that meets you company's complexity policy

5. Click to select the Account is disabled check box, and then click Create.

When You Install Exchange 2000 on a Domain Controller

Create the EUSER_EXSTOREEVENT account in Active Directory, and then disable the account. The following steps outline how to create an account in Active Directory:

1. Start the Active Directory Users and Computers MMC snap-in by clicking Start, pointing to Programs, pointing to Administrative Tools, and then clicking Active Directory User and Computers on the domain controller for the domain in which Exchange 2000 will be installed.
2. Click the Users container.
3. On the Action menu, click New, and then click User.
4. In the New User dialog box, fill in the following information:

   Full Name: EUSER_EXSTOREEVENT
   User Logon Name: EUSER_EXSTOREEVENT

5. Click Next.
6. Provide a password that meets your company's password complexity policy, and then confirm it.
7. Click to select the Account is disabled check box.
8. Click Next, and then click Finish to create the specified account.

After Setup

Manual Procedure

After you complete Exchange 2000 Setup, Microsoft recommends that you delete this account to minimize the potential security risk that the well-known account represents. If you are using this account for other reasons, at a minimum, reset the account password to ensure the security of this account.

Tool to Automate Procedure

As an alternative to the manual process described above, you can obtain the following tool from the following link to automatically correct this security vulnerability: The following file is available for download from the Microsoft Download Center:
For additional information about how to download Microsoft Support files, click the following article number to view the article in the Microsoft Knowledge Base: Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help to prevent any unauthorized changes to the file.

• This tool requires the currently logged-on user to have either Administrator privileges to the local computer for member servers, or Domain Administrator privileges for domain controllers. This tool extracts itself into the C:\Temp folder. After it has been extracted, follow the directions outlined after the extraction is complete.
• For member servers: This tool searches the local account database, and deletes the account in question. Microsoft recommends that you run the utility from each member server on which Exchange 2000 has been installed.
• For a domain controller with Exchange 2000 installed: Run this utility on a domain controller. It deletes the account from Active Directory. In environments with multiple domain controllers, this account may continue to exist on other domain controllers until Active Directory replication has completed.

IMPORTANT: This tool only deletes the account in question. It does not prevent the original setup error from occurring. You must still follow the manual process of creating, and then disabling the account before you run Setup to avoid the setup error. After Setup is complete, you can manually delete this account or remove it using the tool provided.
