Gary -
I've been thru hell and back trying to do the same thing.

It sounds like you're trying to execute remote commands on a PC at home or
elsewhere, (at least remotely from the System i box...)

I'm not sure I'd believe the ISP about not blocking ports. Just to prove
this, I'd try setting it up on a PC that is attached locally to the same LAN
as the System i and verify that it works. If it works on a locally-attached
PC, then it is a port blocking problem by the ISP or the firewall between
the System i and the ISP.

Hi Scott,

Thanks for the reply.

Sorry if this is an obvious question, but...

Do you have a firewall on your WinXP machine? (WinXP comes with one
built-in, and there are many, many, many third party ones available.
Just about every virus scanner suite comes with it's own. I often look
at people's computers, only to find that they have 3 or more firewalls
running at once!)

If you have a firewall, have you configured it (or "them") to allow
connections on port 512?

Good question.

In my original email I enclosed:
"I have put an exception in the windows
firewall to allow port 512 and to allow the program
cwbrxd.exe. I have also turned off the windows firewall."

I will insert my original email so everyone can know what I have done so

Original email:
I'm running into a problem getting the Incoming Remote command to work in

I have it working fine in '98 so I know the AS/400 side is setup correctly.

I have tested port 512 with Port Detective and it says it's blocked. Port
Detective test the port from the PC to the outside world. I have put an
exception in the windows firewall to allow port 512 and to allow the program
cwbrxd.exe. I have also turned off the windows firewall.

I have turned off the Client Access Express Remote Command service and
to see if any other programs were using port 512 with a program called
Ports. It shows nothing is using port 512.

I have checked with the ISP Road Runner in Southern California and they say
don't block any ports.

In XP sp2 I have setup a user with Administrative Rights that the Remote
Command is using with the password in all upper case.

In services for "Client Access Express Remote Command I have set the Log On
use the same Account as the User that the remote command is using with the
password in all upper case.

I have added the user in Control Panel, Administrative Tools, Local Security
Policy, User Rights Assignment:

Act as part of the operating system
Create a token object
Create permanent shared objects
Increase scheduling priority
Log on as a batch job
Log on as a service
Log on locally
Replace a process level token

I have taken the remote command and run it from a command line with the same
user. It runs fine.

I have tried logging in under the same user and running the Remote Command.

I am not getting any error in V4r4 running Client Access Express V5r1 with
latest service pack. The system is waiting on a timed wait.

I can understand it not connecting with port 512 blocked. I can't
what is blocking port 512 unless Road Runner isn't giving me the true scoop.

I have also tried this on a different ISP - Port 512 is still

What else could be blocking port 512 in XP?

Thank you,

Gary Kuznitz

What command are you trying to run?

The command I am running is:

The RMTLOCNAME = a real IP address
The RMTPWD = a real password
Please remember, this is running fine in Win '98.

Thank you,

Gary Kuznitz
