Question

Cannot install Microsoft Remote Desktop ActiveX control

Asked by: Duncan007

Hello,

I cannot get the Microsoft Remote Desktop ActiveX controll installed on one particular PC (connecting via SBS2003 Remote Web Workplace)... when I get to the place where I can say that I want to connect to client desktops, I keep getting the message...

"This portion of the Remote Web Workplace requires the Microsoft Remote Desktop ActiveX Control. Your browser's security settings may be preventing you from downloading ActiveX controls..."

Ok, normally you would install the ActiveX control once, and you would not be bothered again on future visits... but I cannot get it installed... putting Internet Explorer's security settings down to the lowest possible does not help... reseting IE back to all the defaults does not help either...

I am sure this is a problem in the registry... this PC was previously part of a SBS2003 network but was removed from the domain and put back into Workgroup mode (the end-user took it home)... I know SBS2003 pushes down a group policy to any connected PCs... I have a hunch that even though this PC was removed from the domain, there may be some left-over policy settings...

Thank you in advance for your help.

Just venting to start--- Why did a company allow a PC to leave an office with out a FULL WIPE and reinstall??

OK seriously I would reformat and reinstall the PC… I have found it is a lot smoother if I do a full exorcism in a situation like that…

Plan B would be to read “How to Use the Group Policy Editor to Manage Local Computer Policy in Windows XP” (http://support.microsoft.com/kb/307882/)
Then follow it up with a repair install of the OS.

Plan C: I use VNC in many cases.

 

by: TechSoEasyPosted on 2007-01-04 at 20:52:21ID: 18249387

I'll agree with gm_iii's first point.  You really should wipe and reinstall any machine that leaves the company.

I wouldn't agree with Plan C, however.  There's no need to use VNC with an SBS network, especially for ease of management for users to access their workstations in the office.

At any rate... if you don't wipe and reinstall, then please delete the following file:  C:\Windows\Downloaded Program Files\Microsoft RDP Client Control (redist) and try again.

also check any popupblockers including those from google and yahoo and ensure they arent blocking the activex install.

 

by: Duncan007Posted on 2007-01-11 at 14:50:06ID: 18297341

I tried Group Policy Editor... no luck here.

I could not find C:\Windows\Downloaded Program Files\Microsoft RDP Client Control (redist)... it did not exist here... also searched the entire C drive... could not find it.

There are no pop-up blockers or 3rd party toolbars.

I tried a different / brand new user profile... same issue.

Also tried Firefox with an ActiveX add-on... same exact issue as IE... same exact message... I can however install other ActiveX controls, such as Flash and Shockwave.

Does anyone have any idea at all on how I can fix this without redoing the OS???  I would really appreciate it.  Thank you.

 

by: AndrewJDavisPosted on 2007-01-11 at 15:03:01ID: 18297440

for the ammount of time you are going to be spending on this, and the fact that there will probably other issues sometime down the track, you really should look at a fresh reinstall. is there any good reason not to do a fresh install, ie. custom application that you no longer have install software for.

 

by: Duncan007Posted on 2007-01-11 at 15:21:53ID: 18297558

This was the owner of the company's PC... he has quite a bit of software installed on it that he uses for personal use... it can all be reinstalled, but it would be quite time-consuming to do so... if I could get past this one issue I would be done with this project... otherwise I am looking at 3 to 4 hours of additional time to redo this bugger... :-)

 

by: AndrewJDavisPosted on 2007-01-11 at 15:29:19ID: 18297594

okay so you are truying to connect the computer to the terminal session via the web based interface. can the client use the remote desktop client?
start > programs > accessories > comunication > Remote desktop connection
or Start > Run   mstsc

then you can save a shortcut to his desktop.

I am using Remote Web Workplace (SBS2003)... In answer to your question, I think that there may be a way to connect to RWW using the remote desktop client... but I don't know how to set that up... never have tired it.

Currently, I connect using IE... https://<server address>/remote... RWW uses ports 443 and 4125... Remote Desktop normally uses 3389... which is not currently being forwarded on the router...

 

by: Duncan007Posted on 2007-01-17 at 12:01:18ID: 18335403

Can anyone help with this???

 

by: AndrewJDavisPosted on 2007-01-17 at 15:33:21ID: 18337084

as this is in the XP topic and it really is related to the operation of remote web workspace, i would recomend you post a pointer question in the SBS 2003 Topic.

 

by: AndrewJDavisPosted on 2007-01-17 at 15:35:06ID: 18337098

do any other users outside he office connect to the RWW?
Could it be a port forwarding issue at your router?

 

by: Duncan007Posted on 2007-01-17 at 15:49:16ID: 18337167

This question should have been posted on the 3 most relevant boards... unless I did something wrong when I submitted the question... anyhow it works fine from other computers, it is most certainly a Windows XP issue with this particular PC.

 

by: AndrewJDavisPosted on 2007-01-17 at 16:21:33ID: 18337303

do any other users outside the office connect to the RWW?

 

by: AndrewJDavisPosted on 2007-01-17 at 16:22:53ID: 18337306

RWW uses port 4125 is it being port forwarded at the router?

 

by: TechSoEasyPosted on 2007-01-18 at 12:40:22ID: 18344586

Duncan007, don't worry about the topic areas... you've posted your question on the new site which DOES put it in the appropriate areas... no need to repost anywhere.

If you didn't find Microsoft RDP Client Control (redist) then the ActiveX plug-in hasn't been installed.  So, I wonder if the "Downloaded Program Files" folder is operating properly, or if you have wrong permissions on the C:\Windows folder.  There also could be a local policy in place that's preventing installation of ActiveX.

So, please run this command on the workstation:

gpresult /z >C:\gpresult.txt

This will create a text file as noted in the command... you can post the contents of that here for analysis.

I found this solution provided by Microsoft that may fix your issue.
http://support.microsoft.com/kb/555235/en-us

I am having the same problem but it works when I log into my company RWW but a different companies RWW.  Let me know if that helps.

 

by: TechSoEasyPosted on 2007-04-12 at 12:49:52ID: 18901069

As a followup, I have recently experienced this same problem elsewhere and found that if you put  https://<server address>/remote into the trusted zone of IE, close IE and restart it, then it should allow the ActiveX download to install.

First Turn off any Pop Up blockers
  Tools then select pop up blocker and then Turn off pop up blocker

If you are using IE and in the administrator's account, follow these steps to enable Active X.

- Select Tools, then Internet Options from the menu at the top of the Internet Explorer window. The Internet Options window will appear.
- Select Security from the list of tabs at the top of the Internet Options window. The Security tab will appear.
- Select the Custom Level button. The Security Settings window will appear.
- Scroll down to the Download signed ActiveX controls entry and select the prompt radio button.
- Scroll down to the Run ActiveX controls and plugins entry and select the enable radio button.
- Select the OK button to accept the changes

For anyone that stumbles upon this, I've been looking at a similar issue.  I was looking to automate a way for non-domain computers (Home Users).  Group policies can be used by using the "Manage Add-Ons" part of the computer poilcy.  Basically it adds the following registry keys.  This is for several different versions of the "Microsoft RDP Client Control (redist)":

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Ext]
"ListBox_Support_CLSID"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Ext\CLSID]
"{4eb89ff4-7f78-4a0f-8b8d-2bf02e94e4b2}"="1"
"{7390f3d8-0439-4c05-91e3-cf5cb290c3d0}"="1"
"{a9d7038d-b5ed-472e-9c47-94bea90a5910}"="1"

Also, here's a little VBScript that I put together that will add the registry keys if the ActiveX control is installed, and will download RDP 6.1 if the ActiveX controls are not found.
