As long as each computer, client and host, have their own AntiVirus Program, they should be fine. As for security, you need to get a firewall, which will prevent anyone from attacking either pc.
As for prottecting the actual connection, you will need to set your session to the highest form of encrytion. This needs to be done by the administrator of the AdvServer Host or Win2k host. I am the administrator, and I go into Terminal server configuration. My security is set at 128-bit which should keep those punk a$$ script kiddie b$stards from messing with it...
Where are my manners...:Q
I don't have anything important on there anyways... 😀
hope this helps...
EDIT: HAD TO CENSOR MY SCRIPT KIDDIE BASHING FOR THE KIDDIES😉
