RWW Screen Colour Depth Question

On Microsoft » Microsoft Small Business Server (SBS)

Hi Guys,

Is there a way to force screen colour depth and resolution for RWW

(External)clients?

I know how to do this for LAN based clients ie. Through TS manager, but

these settings do not seem to apply to clients who access the system through

RWW.

The end users who use RWW are not "Remote Savvy" so it would be a big help

to be able to enforce a screen colour depth and resolution.

Best Regards

Steve

    • Hi Steve,

      Haven't tried this, but...

      I think you should be able edit the Small Business Server Client Computer

      Group Policy (or maybe create a new one) to restrict the color depth of TS

      sessions to your client computers:

      Server Management | Advanced Management | Group Policy Management | Forest |

      Domains | <you domain> | (rt-click) Small Business Server Client Computer |

      Edit | Computer Configuration | Administrative Templates | Windows

      Components | Terminal Services

      In the right pane, click on "Limit Maximum Color Depth", enable it and set

      the desired value. (You may need to run the command: gpupdate /force on

      the server and clients to get the group policy to take effect immediately).

      As for the screen resolution, in my playing, I haven't found a way to modify

      the RWW Screen Resolution drop down list (under Options) to default it to

      anything other than "Full Screen".

      I don't think screen resolution is going to be a problem unless the LAN

      computer has a setting that is less than the remote computer. Example: the

      remote (home) computer is set to 1600 x1200 and the LAN computer is set to

      1024 x 768. In this case, the user of the remote computer must drop its

      resolution to a value equal to or less than than the LAN computer (1024 x768

      or less), otherwise they may get an "Invalid procedure call or argument"

      error. I haven't seen too many "home computers" using a resoultion greater

      than 1024 x 768, but it could happen. So, if you keep your LAN workstations

      at 1024 x 768, you should be OK for the most part.

      Maybe someone else has some additional comments or suggestions.

    • Hello Steve,

      Thank you for posting to the SBS Newsgroup.

      Thanks a lot for Merv Porter's sharing!

      I understand that you want to know how to improve the colour resolution for

      external RWW clients. If I have misunderstood your concern, please let me

      know.

      Merv Porter is right; he has shown you the detailed steps on how to

      implement it, and already fully explained the detailed screen resolution

      information between local and remote computers.

      I would only add that the higher Color depth you use, the more bandwidth

      will be consumed, so if you choose higher Color depth, it may cause poor

      RWW performance. So you need to balance Color depth and the bandwidth. For

      detailed information, you can double click "Limit maximum color depth", go

      to Explain tab to find the full description.

      Thanks for your time, and thanks again for Merv Porter's great input! If

      you have any further questions or concerns on this issue, please let me

      know. I am looking forward to hearing from you.

      Best regards,

    • I am trying allow RWW connections at 24 bit color depth. I have tried

      following the steps in Merv's post but it still isn't working. I can connect

      from one pc to another internally with Remote desktop and it works at the

      correct color but through RWW it is limited to 16 bit. Any suggestions?

    • Hello Rob,

      Thank you for posting to the SBS Newsgroup.

      I understand that when you tring to use RWW to RDP to client desktop, the

      resolution only can be set as 16 bits. If I have misunderstood your

      concern, please let me know.

      I suggest you that check what resolution is used on the local desktop.

      Because using RWW, the resolution on remote computer must be set less than

      the one on the local desktop.

      Hope this information helps. If you have any further concerns on this

      issue, please feel free to let me know. I am glad to be of assistance!

      Best regards,
