Any Ideas?

I have the report server(RS) on one machine and the report manager(RM) on another.  Both machines are part of a domain and the services are run by a domain services account.  On the report server machine I can access the report server and it works. I can also navigate to the report manager url and it works as well.  From the report manager machine I can access both the report server and the report manager once I turn of the IE Enhanced Security. The report manager using both localhost and the fqdn. I have created a report in BIDS and published it and can view it in from both the report manager server and report server fine. I can also access the report server from a client computer which is a part of the domain.  The issue is when I try to access the report manager from a client computer it will give me "The request failed with HTTP status 401: Unauthorized."   I am using windows authentication, I have made sure impersonate="true" is in the config file properly. <RSWindowsNTLM /> is the only authentication I have: 

<Authentication>
      <AuthenticationTypes>
             <RSWindowsNTLM />
      </AuthenticationTypes>
      <EnableAuthPersistence>true</EnableAuthPersistence>
</Authentication>


The connection to the database is with a special SQL account dedicated to reporting services with ownership to the tables it created and public rights. 

I have no idea why I can't access report manager from a client computer, it has to be something simple I am missing?!?  Any help will be greatly appreciated.

Thanks!
