you may have two options. 1. get VPN client to authenticate on the server with the same credentials that they used to connect to the VPN. check this link.

2. use net sue command to cache credentials, for example, net use /u:username password.

If both sites are using the same IP range, PPTP doesn't in most cases. However, you may modify the routing table to make one to one connection. Another option is us IPSec instead of PPTP.

http://www.ChicagoTech.net should have one case regarding this settings, but I can't find it now. Let me try here again.

Assuming LAN A server LAN IP is 192.168.0.1 and PPTP IP is 192.168.0.11 while LAN B server IP is 192.168.0.2 and PPTP iP is 192.168.0.12. On the LAN B server, you may use this command: route add 192.168.0.11 mask 255.255.255.255 192.168.0.12.

Please post back with the result.

Robert, sorry for late reply (i was outstation) and thanks for the solution.
but sadly it doesn't solve the problem.

if i would to go for ipsec approach, is it achievable in my situation ?
what i want to archive for IPSec links is Scenario A not scenario B:
Scenario A: MyPc ---> Server2003
Scenario B: Router at LocA ----> Router LocB

Thanks for your help.
