New issue using RDC - SBS2k3

Microsoft Windows

For some reason I cannot login remotely to my server using the RDC and the IP
adderess of the routers static IP.

2 nics on the sbs2k6 server
Re-ran the connect to internbet and routing and remote access wizards.
Looked at the open ports on the router again.

Mail is hosted on our server at mail.companyname.com
Where else whould I look at?
Is it normal if using the server as a DHCP, why in ipconfig /all does it say
DHCP "No"?

Greg
depends on how you are attempting to use RDP.

RDP direct to the server requires port 3389 forwarded from the router to
server. Most SBSers do not require this, preferring method 2.
RDP through RWW requires port 4125 forwarded from the router to the SBS. As
well as the ability for administrators to connect to the server this allows
ordinary users to connect to workstations.

All SBS clients should get IP settings via DHCP from SBS, the SBS itself
does not use DHCP to get its address (hence, DHCP=No).
I have both 3389 and 4125 forwarded on the router, that hasn't changed. The
error that comes up when conencting RDC says "Computer can't connect to
remote computer".

It looks like I have everything correct, as it was working fine in the past.
Any other suggestions?

Greg
OK, can you use RDP in RWW to a workstation and if so can you from that
workstation connect via RDP to the server?

The ability to connect RDP via RWW to a workstation would prove that port
forwarding and the RDP proxy are working.
The ability to RDP from the workstation to the server would confirm that RDP
on the server is available.

Another reason for 'Cannot connect..' can be a saturated internet connection
at either the server or remote end.
I'm using RDC from a computer locally on the network. I can RDC to another
workstation, but I cannot RDC to the server using the static IP of the
router, which is what I do offsite.
Has what you are attempting to do ever been sucessful? If so, what has
changed?

Yes, I've always been able to RDC from home directly into the server by using
the routers Static IP, I don't have a clue what changed or how.
Yes, you can and should be able to do it from home or anywhere outside the
LAN. My question was, have you ever been able to RDP from *inside* the LAN
to the public IP of the router, which is *outside* the LAN.
and in most cases is expected not to work.
Yes, a very few recent and some older (higher end?) devices handle the idea
of 'reflection' (what I have always called 'loopback connection/processing')
correctly.

I think that 'in most cases is expected not to work' is still valid though.

I will mention that the Calyptix Access Enforcer has a feature called TCP/IP
reflection, which actually allows this work.

Yes, I can connect RDC to the servers IP, no problem on the network.
