How to prevent warning "unknown publisher" while opening any RDP-files on Windows XP workstations in a Windows 2003 domain?

    Pregunta

  • How to mandatory prevent warning "unknown publisher" while opening any RDP-files on Windows XP workstations after SP3 has been installed in a Windows 2003 domain?

    Is there some .adm file (administrative template) for Windows Server 2003 with the "Allow .rdp files from unknown publishers" setting?

    Is it possible to sign the .rdp file by rdpsign.exe utility on Windows Server 2003 or Windows XP and where is it possible to download that rdpsign.exe?

  • Hi,

    Thanks for your post.

    In server 2003 with client XP, we cannot get rid of this warning. The prompt will always show because the RDC always assumes the server is unsafe. If deployed TS server in Windows 2008 or R2, with correct certificates issued, you can make the warning not showing up again.

    For more detailed information, please refer to the following blog. Hope it helps.

    “Unknown Publisher”? Where did this dialog box come from?

  • Hi,

    rdpsign.exe is included with Windows 7 so if you have a Windows 7 PC you could use that to sign your rdp files.  You need to sign them with a certificate that is trusted by your PCs.  For example, a certificate issued by a trusted public authority such as GeoTrust, GoDaddy, Thawte, Verisign, Globalsign, etc. will work for this.  Single-name certificates are available for less than $10/year.

    Users will still be warned when opening a .rdp file signed by a trusted certificate, however, users will have the ability to select Don't ask me again for remote connections from this publisher so that in the future they will not be prompted.
