Windows SBS 2003 - Remote Web Workplace - Connectivity to Remote Computer could not be established.

I am running Windows Small Business Server 2003 with 7 Windows XP Client Computers.

Using Remote Web Workplace I  have been able to connect to 4 client computers so far but when I try to connect to the remaining 3, I get the following message:

"Connectivity to Remote Computer could not be established. Ensure that the remote computer is on and connected to the Windows Small Business Server."

I have checked the typical:
Remote Desktop enabled on the client.
DNS records are there, etc.
Plus I have tried a few things like opening port 4125 in the client firewall but w/out luck.

These 3 computers use to belong to a different domain and were disjoined properly. One of my thought were that perhaps there were some settings that somehow remained from the old domain (Obviously, I am just guessing on this one)

Thanks in advance for any suggestions. (Desperate!)

Have you checked to see if the built-in firewall on those XP machines is disabled (or set up with the proper exceptions)?  You might want to just disable the built-in firewall completely and then try it to see if that works.  If you need the firewall running, then after you made sure the remote web access works, you can enable the firewall and add the proper exceptions.  Assuming you are running Windows XP with Service Pack 2, you can access the firewall through Start >> Settings >> Control Panel >> Windows Firewall.

You might also want to check if there are any other 3rd party firewalls in place (Blackice, Norton, Mcafee, etc).  Disable those if you find them.

Jeff,

Thanks for you quick response.

As far as I can see, there are no 3rd party firewalls installed and I have opened port 4125 in the XP firewall.

In a different note. I have never been able to disable the XP firewall once the computer has been joined to a domain.

I will look further into the 3rd party firewall possibility...

Thanks again and I will keep you posted on any progress.

It sounds like there is a group policy setting that is preventing users from disabling the firewall.  

What you could try to do is disabling the firewall service itself.

Start >> Run >> services.msc

Now scroll down until you see the "Windows Firewall/Internet Connection sharing (ICS)" service.  Right-click on it and select Stop.  Now go try your remote web access.

Jeff,

Tried that and still got the same message. The good thing (and thanks very much for that) is that I learned how to disable the firewall service.

Any other suggestions?

Ok, do you know if the user account you are using to connect is a member of the Administrators or Remote Desktop Users group on this PC?  If you are using a domain administrator account, this should be working fine.  If you are using a domain administrator account and it still isn't working, try adding your account to the Remote Desktop Users group on the local PC and then try to connect remotely.

Jeff,

I checked everything you suggested and still no luck.

I tried to do a Remote Desktop Connection from the server to the workstation and got the following message:

"The client could not connect to the remote computer....etc"

?

Well that's strange.  Have you tried from one PC to another?  Can this "broken" PC connect to a working PC using Remote Desktop Connection?  How about the other way around?

Also, have you seen this Microsoft article:
http://support.microsoft.com/?kbid=828053

It has a lot of scenarios where this could fail and solutions to those problems.
