Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003, Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.
To verify that the legacyExchangeDN attribute for the new administrative group already exists, follow these steps:

1.	Click Start, click Run, type Adsiedit.msc, and then click OK.
2.	Open the following item: CN=Administrative Groups,CN=Organization name,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain name,DC=com
3.	Compare the legacyExchangeDN attribute of the new administrative group with the legacyExchangeDN attributes of the existing administrative groups.

Note The Windows Support Tools include the Adsiedit.msc tool. The Windows Support Tools are located on the Microsoft Windows Server 2003 Setup CD.
