While you are installing Exchange Server 5.5 on a Windows 2000-based member server, you receive the following error message after you enter the service account information:

Account information is bad.


The Exchange Server service account does not have the required permissions.


To resolve this problem, add the Exchange Server service account to the local Power Users group or local Administrators group on a member server. On a domain controller, add the account to the built-in Administrators group.


The minimum rights necessary for the Exchange Server service account on a member server are Power Users rights. However, if installation problems occur when you use the local Power Users group, add the Exchange Server service account to the local Administrators group. Also, if the local Power Users group is not available because of the type of installation that was performed, use the local Administrators group.
