using the Pocket PC as server doesn't work

Hello,
I tried to do the first steps with using the NetDemo program.
When I use the Desktop PC as server and the Pocket PC which is connected via active sync as client it works perfect. I took the ppp_peer alias as well as the IP address 192.168.55.100.

Doing it vice versa: Pocket PC is server and desctop PC is client I cannot get any connection. I tried to enter the Pocket PCs name and I tried the IP address 192.168.55.101 on desktop PC side. But it doesn't work.

What must be entered when using the Pocket PC as server and the desktop PC as client (Pocket PC uses Active Sync, desktop PC has Windows XP).

Devices connected by ActiveSync cannot accept incoming connections so cannot act as a server. To do this a device must be connected directly to your network, e.g by WiFi.
