Hello Pinter,
Thank you for posting to the SBS Newsgroup.
I understand that you cannot RDP to client workstations neither from LAN
nor from the Internet, but you can RDP to the server. If I have
misunderstood your concern, please let me know.
Based on my experience, most of this issue is caused if a process that is
running on the Windows Small Business Server-based computer is listening on
Transmission Control Protocol (TCP) port 4125. To do so, please take your
time and refer the following KB article to perform a test:
Users cannot connect to remote desktops by using the Windows Small Business
Server 2003 Remote Web Workplace
http://support.microsoft.com/?kbid=886209
If the issue persists, please check:
1. Can you ping the problematic client workstations' netbios name?
2. Can you RDP from the server to client workstations?
3. Make sure that the TCP 3389 is opened on the client workstations. This
is because when you try to connect to client desktops or server desktops
from RWW, the SBS server tells the clients to initialize a connection on
port 4125. If the connection is establishes the server will deliver the
terminal service connection to the destination computer on the normal
Terminal Service port 3389. This is a by-design in RWW.
4. Just a double check, on the problematic client workstation, right click
My Computer, go to Remote tab, make sure that the box under Remote Desktop
is being checked.
Hope this information helps. If anything is unclear, please feel free to
let me know. I am looking forward to your reply!
Best regards,
Brandy Nee
