Samsung BlackJack (WM 6) only sync as Guest

I am real pleased with my Samsung i-600 (blackjack)
I am als realy happy with my Vista Bussines (64 bit) system

but.. They are not happy with eachother. My BJ connects with WMDC but doesn sync or setup a relation.

I already tried the following

- reinstall WMCD
- reinstall WMCD Update
- deinstall Norton security
- deinstall Samsung software (after connecting mobile it installs itself)
- soft reset (baterij out for 20 sec)
- Hard reset
- standard Windows Firewall disabled
- with CMD /ipconfig there apears to be an 169.25.2.2 ip adres
- IP renew get the same ip adres
- Tried multiple usb connection on my system itself (no usb hub or anything like that)

- de services that WMDC uses are all there and are running. The following services are all active:

COM+ Event System
DCOM Server Process Launcher
DHCP Client
Windows Mobile 2003-baased device connectivity
Windows Mobile based device connectivity
Remote Procedure Call (RPC)
UPnP Device Host

Note.

- het valt mij op dat mijn Black Jack zich aanmeldt als gast (dat kan gewoon niet goed zijn)
- It appears that My BJ is connecting to my system as a guest
- I tried to hard reset BJ again but no such luck
- I read on the internet that a previous realtion must be deleted but i cant find any our there isnt one
- in het sync centrum zie ik wel bij relaties staan; Gast, SGH-i600 en verwisselbare schijf.
ik weet niet hoe ik deze kan verwijderen.
- In the sync center i do see some realtions called: Gast, SGH-i600 en removable disk.

-- if i click on guest WMDC opens but i cannot settup a realtion our sync (see picture). It says that there is a problem withe te connection and that i should try to do this again.
-- if i click on SGH-i600 there appears a button called "instellen" in English that should be something like "setup" our "settings" by pushing this button window mediaplayer opens

I have no idea on how to fix this problem, has anyone else got an idea?
