Now, do I need a separated DHCP server(win2000ser) for SRST.I know I can configure DHCP services on SRST router. But my remote office have total over 200 endopint (incluning phones and PCs),only SRST router provide DHCP for phones and PCs , may the performance be a question?
Performance is going to depend on your router platform. Even with that being said, DHCP leases can be configured for a period of time. Extend your leases if you are worrying about performance.
