Error Message

[Kendra Ward]

I have installed RealVNC Free Edition on four computers in a network behind
a Linksys router.  I configured the router with port forwarding for all four
computers.  I configured the options at each computer so that the connection
is accepted at the appropriate port number.  The password has been set.  I
am at a fifth computer outside of the LAN.  192.168.1.51 is port 5900 and
works with no problems.  

 

These ones don't work:  192.168.1.50 is 5901, 192.168.1.52 is 5902 and
192.168.1.100 is 5903.

 

I get these error messages when I attempt to connect to these three:

 

No matching security types.  Do you wish to attempt to reconnect to
xx.xxx.xxx.xxx:2?

 

OR



Server license key is missing, invalid or has expired.  Visit
http://www.realvnc.com <http://www.realvnc.com/>  to purchase a licence.  Do
you wish to reconnect to xx.xxx.xxx.xxx:3?

 

 

I have reinstalled the program on these three computers and nothing has
changed.  I would really appreciate it if someone could give me some help in
what I'm doing wrong.  

 

 

Thanks a lot for your time!
