RE: VBScript: Remote Desktop Disconnected

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi Brandy,

Thanks for your suggestions.

1. I do not have a hardware firewall or router in front of the Internet
computers.

2. ISA is allowing OUTBOUND port 4125 through the "SBS RWW Inbound Access
Rule".

3. The command netstat -aon | find ":4125" returns no results.

4. When running CEICW, I have checked the box "Remote Web Workplace".
=================
Information you requested:

a. On my lan, if I attempt to connect through
https:\\www.domainname\remote, I can connect to RWW. When I attempt to
connect to client or server desktops, I get the following error:

"The client could not establish a connection to the remote computer. The
most likely causes for this error are:
1)Remote connections might not be enabled at the remote comptuer.
2)The maximum number of connections might be exceeded at the remote computer.
3)A network error might have occurred while establishing the connection.
4)The Remote Web Workplace designated port might be blocked by a firewall."

On my lan, if I attempt to connect through https:\\servername\remote, I can
connect to RWW and I can connect to client and server desktops successfully.

b) I was not able to forward the icwlog.txt file to the email address
provided ('v-branee@xxxxxxxxxxxxx'). The bounceback message states "Reason:
Illegal host/domain name found".

c) As per Kathy's suggestion, I attempted telnet <Public IP Address> with
the following results: "Could not open a connection to host on port 4125 :
Connect failed"

d) I am not sure if this is the same as a), but RWW-RDP to server and any
client works from any computers in the LAN.

e) I have attempted the connection from two external computers, one is
Windows 2k, and one is Windows XP SP1.

I hope that is all the information you needed.

Thanks for your assistance.
