Cannot detect RealVNC at windows startup

Hiya pal

To set the port manually for VNC

1. Open CP
2. Goto "Windows Firewall"
3. Click "Advanced Settings"
4. Click "Inbound Rules"
5. Click "New Rule"
6. Select "Port" click "Next"
7. Select "TCP" enter 5900 in the Specific local ports section click "next"
8. Select "Allow this connection" click next
9. Choose the appropriate options under "Domain" "Private" & "Public" click next
10. Give the rule a name eg. VNC out click "Finish"

Repeat the above for "Outbound" aswell and give that another name

Pal if your battling with VNC why don't you have a look at Team Viewer, maybe this will give you better results .... have a looky here Team Viewer Tutorial by DocBrown

Hope this helps a bit
