Exchange 5.5 & Windows 2000

Hi all;
I’ve been trying to configure a Exchange Server in a remote site. When I tried to set up a new Dynamic RAS Connector, it won’t read the RAS Phone Book. It looks like it is trying to read the Dial Up Networking phonebook entries that used tobe in Windows NT, but like in Windows 2K the name is different it simply refuse to accept it. I’ve install Exchange 5.5 Service Pack 4, but didn’t help much. Thank you.
