VPN problems on Androdi (PPTP)

Greatings!

I am having problems connectiong my Android device (Samsung Galaxy S2) with MS Windows Server 2003 (small business premium version) with VPN.
I am using PPTP protocol. I have open required ports on firewall (tcp 1723 and gre). Also let me say that connection is working over notebook (windows 7) and mobile device (windows mobile os).

I dont know why my android device cant connect :(
I dont see anything in logs (windows server, router). Also android device doesnt say much about why it cant connect - it just says that it cant and that the firewall is blocking it. But as I said other devices work and firewall doesnt report any problems.

Thanks for suggestions!

what policy on your rras server ? does it require CHAP or V2 or other encryption?

does it request domain to logon?
simonlimon

are you connecting with gprs or wlan? Do you have the 'enable encryption' check box selected? I have that on my S1. Other than that I see no relevant settings on the phone.

You can check the type of connection in the event viewer 'application'.

Also you can turn rras tracing to help you:

Also I have googled and found that some have disabled encryption and that fixed, you can try clearing the encryption checkbox on the phone.
