Issue with Remote Desktop MMC Plug in

Hello,

Something has changed on one of our networks to prevent a Remote

Desktop MMC from logging into remote desktops without prompting for

password. We used to be able to click on any remote desktop in the

list and it would just log in without prompting but now the remote

machines are prompting for password despite updating the passwords

stored in the connections.

I checked the policy thoroughly and also ran rsop.msc to make sure a

policy wasn't doing it.

Any ideas?

Thanks,

Tom
