But AFAIK you should be able to use VNC without installation, just by starting a batch file - which is ok for internal use.
Do you have LAN access to the remote machines?
How many VNC users are we talking?not many. Almost all the PCs at our company have logmein installed. However somehow it never fails that somebody has some problem in some PC that does not have it.... Then somehow I wind up wasting half an hour just trying to get into their PC and do stuff... I want a way that I can reliably get into a PC remotely in seconds/minutes... I have somebody standing in front of the remote PC on the phone... And I have access to the same local network...
