We are trying to connect some Android 2.3 phones to our SBS 2003 server through VPN. The phones will connect to the VPN, but only with the PPTP Encryption option unchecked, and what is the point in that?
I want to know why can the iOS devices and PCs connect correctly, but Android always pops back saying,
"Server negotiation failed. The server may not agree with your encryption option. Do you want to check your encryption setting?"
I am able to connect to a Server 2008 R2 VPN connection at a different site with no problems on the same phone.
Any ideas on how to get this going with encryption would be appreciated.
