Disable remote desktop connection security warning

[Guy Yardeni]

Hi,
I'm deploying a TS solution and automatic client machines so that they auto
login and then launch the RDP client and connect to the TS farm. On first
connection, they get the security warning because the client drives are
redirected to the server. There is a checkbox on the warning to never warn
you again for this server, I'd like to pre-deploy this to all client machines
- it is stores in a registry key or another place that can be accessed with a
script?
My servers are Windows 2003 and clients are Windows 2000, XP and XPe.

Thanks,
Guy

You can prevent the security prompt by adding the following registry
key:

HKCU\Software\Microsoft\Terminal Server Client\Local Devices

For each server name, create a REG_DWORD with a value of 1.
So if the server is called myserver.mydomain, create
"myserver.mydomain"=REG_DWORD:00000001.

Vera,

do you know the meaning of the possible values of the Registry entries
in "LocalDevices"? On my XP machine I have a value of 13 for each
server, which is obviously a bit mask consisting of the bits 1, 2 and
4 set.

Thanks, Helge

Hi Helge,

I've spend the better part of the weekend searching, but haven't
found any reference other than to value 1.
Guess one could configure different connections and watch the
registry value change with them, but I'll leave that as an exercise
for the reader :-)
