Hi Dieter,
RWW is the 'killer app' of SBS2003, I've heard rumours that ENTERPRISE
Network Admins SALIVATE over the possibility of stealing it from SBS space.
Your boss and you have XP workstations at work? Instead of turning them
off at night, leave them on. RWW will give you the ability to connect to
them securely from anywhere in the world (as long as certain ports are
accessible through whatever firewall you are behind).
RWW is actually a set of web pages, available from https://SBSname/remote
when internally connected to the network and https://FQDN/remote when coming
in from 'outside' the network. RWW allows you to read email stored on the
server, connect to XP desktops, connect to terminal servers on the network,
access the CompanyWeb, download a preconfigured VPN client, AND MORE.
Allowed users can observe Performace Reports, control the SBS itself, all
sorts of great stuff.
How does this negate the need for VPN?
Allowed users can establish a secure HTTPS connection to the server, then
take control of their XP workstation in the office through a process known
as RDP Proxy, 'Connect to My Computer at Work'. If you have a Terminal
Server on the network, and the user is correctly permissioned, you can also
'Connect to my Company's Application Server'. Many tasks which are slow or
unreliable over VPN (accessing a large database comes to mind) work quite
well over RDP Proxy, due to the fact that only screen updates move across
the 'external' connection, access to the database happens at local network
speed.
Ports required for RWW:
443 (HTTP SSL) Most remote systems should allow this.
and that's the complete list. If you allow it, incoming requests to port 80
(http://fqdn/remote) will automagically switch to HTTPS.
Additional ports which you may wish to access:
444 CompanyWeb https://fqdn:444 (can be problematic for remote firewall
systems. Not all remote firewalls [ISA included] will allow HTTPS on this
non-standard port). I'd rather, and it can be manually done,
https://fqdn/companyweb (ie. companyweb _appearing_ to be on the standard
HTTP SSL port, port 443)
4125 RDP Proxy. The RDP Proxy is enabled by RWW loading an ActiveX control
into IE. There is a distinct possibility that a remote system (say that in
the 'Business Center' of your hotel) will block the installation of such
controls. This is good, we don't want fully public (viri infested) PCs
accessing our network. However, if we are on a computer we can _reasonably_
trust (Say, Aunt Gladis' PC) we can work 'as if' in the office from
thousands of miles away.
1723 PPTP VPN (IF YOU MUST) I allow VPN into my LoungeAN because I feel I
have 'special needs', I use it on EXTREMELY rare occassions. (actually, I
can't remember a time in the last 6 mths, maybe I should disable it)
