VPN connect from Windows 2003 to Routerboard

Hi there!

I hope I’m in the right category.
I have a Windows 2003 Server which connects to 4 different RB750 (RouterOS v4.2 installed). It works very well when starting the connections while the system is running. When I’m trying to start these connections at startup (with scheduled tasks), only one of these four connections is working fine.
What I’m unsure about is the fact, that the Windows 2003 Server is connecting to every RB750 - is authenticated and (regarding the log) even logged in. Even though it’s just for a moment.

Here is a part of the log where it didn’t work (3 of 4 Routerboards):

11:26:39 pptp,info TCP connection established from xx.xx.xx.xx
11:26:39 pptp,ppp,info <pptp-0>: waiting for call... 
11:26:39 pptp,ppp,info <pptp-0>: authenticated 
11:26:40 pptp,ppp,info <pptp-0>: connected 
11:26:40 pptp,ppp,info,account mon logged in, 10.20.1.250 
11:26:40 pptp,ppp,info,account mon logged out, 1 134 130 8 10 
11:26:40 pptp,ppp,info <pptp-mon>: using encoding - MPPE128 stateless 
11:26:40 pptp,ppp,info <pptp-mon>: terminating... - call cleared 
11:26:40 pptp,ppp,info <pptp-mon>: disconnected

Anyone an idea how to handle this problem?
It’s important that the Windows 2003 server reenables all of the VPN connections at reboot…

The batch scripts which are trying to connect are just like this:

rasdial connectionname mon password

They are working fine (all of them) when they’re started manually…

Thanks in advance for your help :slight_smile:.

Are you sure Windows is not doing anything to the tunnel configuration?
Enable PPTP,debug logs and posts the output here.
