Pino the file explorer on your windows mobile device will only connect to a
share using the server netbios name not the ip (yeah I know would be nice if
it did) so see if you can ping your computer from the device using it's
netbios name. If you can't that means that netbios name resolution isn't
happening across the vpn. You can either install a WINS server on your
network (least favorite thing to do) or use a program on your device that
will map the name to the IP like Pocket Hosts(
http://www.zimac.de/cestuff.htm ). Since you can ping the computer via it's
IP address we at least know that you have connectivity, now we just need to
get the name resolution to work.

If you can establish a vpn connection then you can rule out blockage.
One
quick way of testing to see if GRE is blocked is to try the PPTP
connection
from a desktop. If the connection progress gets hung up trying to verify
your username and password more than likely it's GRE blockage. What I
have
seen is many GSM carriers use private subnets for devices and sometimes
your
internal VPN subnet may fall within the range of the carriers and the
packets are routed incorrectly. A great utility to have is VxUtil from
(www.cam.com) you can use this to trace, trace and many other things.
It's
essential for troubleshooting vpn problems on the mobile device.

everybody......I
wanted to say that I have the same problem of Mark....
In my case ,I get the same error when trying to access from GSM/UMTS
network (Tim.it)to my desktop (ADSL flat --Tin.it).Locally everything
is fine (802.11b --ad hoc).
I think the answer is the mobile provider (TIM.IT) or adsl provider
(Tin.it) blocks -GRE (Ip -47)
or TCP 1723 !!!!!!

HI Eric,thanks for your reply!!!

I do have VxUtils installed on my PDA/PHONE (HTC:TYTN)-windows
mobile5.0---
May you tell me how can I use this software to troubleshooting my
problem ??
(The connection to desktop (win-XP-home/professional) is successfully,
PING works fine,but I cannot see network resources in the VPN server
(XP),firewall is disabled.
In other words :\\192.168.1.100\C (shared) :"you don't have permission
ecc.ecc......").
Furthermore XP-PPTP-VPN-Server is connected via Ethernet
modem--ADSL---.
I start the connection from my PDA/phone via GPRS network..........
Thanks a lot .Ciao from Giuseppe in Italy

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
