Add user to Local Group Error

Guys,

I need help installing SQL Server 2005. I meet all of the pre-req's and setup seems to run normally until it starts installing the services and database engine. I receive the following error:

SQL Server Setup was unable add user NT AUTHORITY\NETWORK SERVICE to local group SQLSERVER2005DTSUser$server.

It repeats the error for for the other groups that are created with SQL install.

Am i missing something that's obvious? I couldn't find anything in the documentation or anywhere else.

Here are a couple of things to try:

1. Check the installation log files, located at %Program Files%\Microsoft SQL Server\90\Setup Bootstrap\LOG\Files for more details on the error.

2. Try to add the service manually to the local groups using the Computer Management Admin tool. Then re-run setup.
