Error: Your computer’s settings do not allow connection to this remote computer


Just want to share some information which might be useful for some of you.

I was playing with a Terminal Services Server (Windows 2008) in a test environment; in particular I was trying different things with TS Web Access and RemoteApps. I have published MS Outlook as a Remote Application available through the TS Web Access, but every time when I was trying to access MS Outlook from the TS Webb Access page (from Windows XP SP3 client PC) I was getting an error:

Your computer’s settings do not allow connection to this remote computer because it cannot be identified. Either it is running a version of Windows that is either earlier than Windows Vista, or it is not configured to support server authentication.

For assistance, contact your network administrator or the owner of the remote computer.

Having checked all setting I found out that the Security Layer for Server authentication and data encryption was set to RDP Security Layer. I have changed the Security Layer to Negotiate and the problem has disappeared.

So, if you will be getting the same error you can check this setting and change it if necessary.

Customizing TS Web Access


Recently I have seen several questions on the Microsoft Forums regarding customizing TS Web Access page. One of the things that people want to know is how to hardcode Terminal Services Server’s IP address into the “Connect to:” field on the TS Web Access page. Another question is how to set the default Remote Desktop Size on the TS Web Access page.

How to hardcode Terminal Server’s IP address on the TS Web Access Page.

1) Open the IIS console on the server hosting your TS Web Access and navigate to the TS website. Inside the website right click on the folder with your language pack (in my case it is en-US) and go to Explore.

2) Right click on the Desktops.aspx and choose Edit.

3) Let us assume the IP address of your Terminal Services Server is
In the Desktops.aspx find this line:

4) Now add this text to the end of that line: value="" (change the IP address to the one you require)

Your line should look like this:

5) Now just save the changes and try to open your TS Web Access page, you should see the IP address of your server already entered into the “Connect to:” field

How to set default preferred “Remote Desktop Size” on the TS Web Access Page.

By default TS Web Access page has “Full Screen” as a Remote Desktop Size. Administrators may want to change this to some different setting. If you want to do this follow these steps:

1) In the Desktops.aspx (see above how to find this file) find this part of the code:

2) Let us assume that you want to set 1024x768 as your default setting, in this case you have to delete attribute selected from the line containing FullScreen and add it to the line containing 1024x768

Your code should look like this:

3)Now just save Desktops.aspx file and check your TS Web Access page. It should look like this
