Users are going to use this over a slow link connection, and it would be helpful to know which one generally does the best to eliminate keystroke and mouse lag.  Thanks

Thanks for the info.  Can you elaborate on the security holes?  And since a VPN is a secure link over which VNC runs, shouldn't that provide some measure of safety?

Commented:
It's not so much the fact as the packet itself is concerned but moreso on how the solution is implemented for authentication.

VNC by default uses ports 5800,5900...  People will port scan for these and then try to establish a VNC connection in the hopes that the Administrator did not enable passwords...  Unfortunately VNC only supports one password and cannot be made to Authenticate based upon Active Directory Account rights.  I can't remember, but I do believe that PC Anywhere is a little more lax on this and does offer Active Directory Account Authentication as well as support for multiple users.

i have enabled passwords on all instances of VNC.

One other thing to assist in securing is to change the default port.

Gotcha.  Do you know if any of them do compression before sending the packets?  

Commented:
If you are going to use a VPN then there is no security risk since you will not allow any access to the remotely managed computers, so the only security problem will be in the inside part of the VPN ie your own network. Changing ports will not have any real difference since in any port VNC will promptly respond.

Commented:
Just to add that VNC supports numerous protocols that add compression and it also supports colour bit reductions as well as JPEG compression. You can try TightVNC which by default offers the Tight protocol with low BW usage, if you are going to install it on windows dont forget to install the mirror driver for better performance.
