That's actually good news, at least we know that the two subnets are not the same. What happens when you try the netbios name in File Explorer instead of Resco?

Hi Eric,
Well I installed Pocket-hosts in my PDA/phone but it did not change
anything....in the sense that I could not see the Disk drive in my
desktop.I get the same error......
In other words : \\Centrino\D or C (shared) gives me the same error ("
impossible to find the network path......or you don't have
permission").
Anyway,for your information ,this afternoon I went to a friend's of
mine home and I successfully
made the PPTP connection( with his ADSL connection )to my home-desktop.
Maybe the problem is in mobile ISP's network ....even if they told me
that" the connection is possible."......I don't know what to
think.....Ciao

Hi Eric,
today I made another little progress...small...in the "PPTP-VPN from
PDA problem"......
I connected my PDA/PHONE to my laptop (via Bluetooth or USB)and tried
the vpn connection to my desktop (XP.home-ADSL).
I COULD MAKE THE connection !!!!
It is just you said : windows explorer (in XP) is much more robust than
in windows mobile 5.0.
I could make the connection but I was forced to disable "the
encription" --in the properties of windows's VPN connection
(PPTP),otherwise an error message said:" The other computer uses a
different encription....connection is not possible".
I also have Resco Explorer in my PDA,but it is the same: the connection
is not possible even
using netbios name (with Pocket Hosts): \\Centrino\D (or C).
Ciao from Giuseppe (Pino)in Italy
