MSExchange Lotus Notes connector

I installed the notes connector in my Exchange 5.5 server according to an article of the MS Technet. When I finish configuring the “Notes configuration utility” it returns a message error: “Cannot write or create file (file or disk is read only) (($VIMPeople))” and the event log records an event ID: 1, Source: MsExchangeCoCo an Description: ENS: 2001/10/01 05:26:37- LME-NOTES-DXANOTES(020b) 1 41104:Error opening Notes database ‘LNserver/LNdomain!!NAMES.NSF’

I already checked the file permissions on the names.nsf, and the user “connector” has the appropriate right: manager. The problem is that user lists between both servers can not be replicated.

Thank you in advance…
