remote connection to a workstation on a windows sbs2008 server based network

Can someone please help me, as this is driving me crazy! I need to connect to my desktop back in the office, and this has been working great using the https://remote.domainname.co.uk facility of Windows SBS2008.

The workstation I am on today is a Microsoft XP Pro SP2. (but I have this problem in a number of locations).

Now for some reason on many different workstations I can no longer connect. I type the URL for the network in a browser, and it presents the logon screen as usual. I then enter the username and password, and we get the small box appearing that has to remain active for the duration of the connection.

We then get the following error message :-

The Microsoft Terminal Services Client ActiveX control (also known as RDP client control) is either not available, or is not enabled. For mor information about installing and enabling this ActiveX control, see the Microsoft Technet Website (http://go.microsoft.com/fwlink/?LinkID=103719).

Now when I look at this it just mentions that when SP3 had been installed there could be a problem and offers a fix it for me option or details for manually enabling ActiveX.

I have tried the fix it for me, but it just says that it is not appropriate for my OS, and does nothing. The workstation I am working at today is only SP2.!! So why should this problem keep cropping up?

I have tried to manage my add ons, but it is not shown, and resetting everything does not achieve anything. Does anyone have any suggestions as how to resolve this, and why is this happening more and more when using various workstations.

Any ideas?

Have you checked if terminal services are enabled?

Firstly to connect to SBS 2008 RWW you need to have XP SP3, Vista SP1, or newer.
This will also install the newer RDP client you will need Ver 6.1 or newer.
The active -x issue is quite common. Assuming you have met the above conditions make sure the Active-x component is not disabled under add-ons in internet explorer and if that doesn't work click the "reset" button in internet explorer under internet options | advanced.

How do I do that? do you mean on the client or the remote workstation? No changes have been made at my office workstation, and I am unsure why this keeps cropping up all over the place.

Could you expand on your suggestion please?

I also assume that RWW was set up and working from some clients. If not you need to run the connect to the internet and configure by internet address wizards.

Following is a good link regarding the Active-x issue:

Sorry Robwill, I replied before your message appeared.

I am not actually using Remote desktop to connect, but just typing the address in the browser. This used to work just fine. I would like to understand why it should suddenly become problematic unless SP3 is installed.

I have tried the reset (using SP2 of course - i will upgrade to Sp3 as you suggest) but why is this happening now?

Many thanks.

probably happending because a update has been applied to the sbs 2008 server.

Did it work with SP2 before? It would work fine with SBS2003 but should cause issues with SBS2008 as I understand it. Very odd. If so it is usually related to the active-x component bing disabled. There are several fixes as outlined, but you often have to try all of them.

ps- can some users connect OK? If so the problem is client side.

Yes, I can connect from some locations but it seems to be getting fewer and fewer.

Sounds like security updates are being deployed to workstations and as it happens it is killing the Active-X add-on.

The strange thing is that ActiveX does not appear in my list of add ons to manage. I can select it from a list to add, and I am told it has completed ok, but it never appears on the list of add ons to manage.

In that case try the reset option.

I carried out the application of SP3 to the xp workstation, and when the little box pops up now, it gave the warning about running activex in the top. When authorising this to run, it still did not connect. I then upgrade to ie v8, and this now works fine.

Does this mean that all workstations anywhere in the worl require sp3 and ie v8 before rdp will now work?

Many thanks.

As I recall you do need XP SP3, or at least the TS connection client components of RDP 6 (included with XP SP3), but you do not need IE8. There are other components in IE that need to be available than just the active-x TS add-on such as accepting cookies. The reset should resolve those, but I assume your installing IE8 did so.

If trying other workstations try installing SP3 and then seeing if you can enable the add-on if needed, without adding IE8.

Probably a good idea to upgrade everybody to SP3. t included a lot of security updates and support for XP SP2 ended as of July this year.
