Can't Map a drive after VPN'd in

[Beaon]

Hello Guru's I am having a problem using the CMAK tool and mapping
network drives.

I want a one click fits all for my VPN users. A file I can send them
without having to walk them through an install and setting up tedious
stuff like map network drives. I want the CMAK to do it for them.

I am having a problem setting this up.

I have hit some problems having the mapped network drive function and
some general network connectivity.

Ideally what I ultimately want to have happen is the CMAk tool auto
map a network drive right after the connection is established. With
some users I may also want a routing table update.

So what I currently have is the CMAK tool logging in successfully then
I have a script set to run on "Post-Connection". Here is the script, a
simple batch file.

net use m: "\\172.16.0.100\Company Files"

Now when the script runs it says the network path is invalid. Even
though you can browse to it with the same path.

Also I originally wanted people to connect to the shares via the
Ethernet interface 172.16.0.2. It won't let me do that and says that
the path is not found, even though you can ping it after the VPN has
been established. It only lets you open a network share via the PPP
interface, 172.16.0.100. Seems dumb to me.

Any how back to the point, when the script runs Post Connection it
says network path not found. If you wait however like 15 seconds and
manually run the command it works.

My question is, why won't it work right after the VPN is established
like CMAK is suppose to do?

Also Why cant I map a network drive to 172.16.0.2, why only the PPP
interface?

Something so simple seems to becoming unnecessarily complicated.

We have two issues here.

1. Assuming 172.16.0.2 is LAN IP address and 172.16.0.100 is PPTP IP
address, it could be the routing table issue. Post the routing table and
ipconfig /all of the RRAS here may help.

2. After run the CMAK, it may take for a while to be able to map. You may
try to add ping 172.16.0.100 before the mapping.

Please post back with the result.

Thanks Robert.

172.16.0.2 is the LAN interface IP of the server. At first I also
thought it may be routing related but you can ping this IP after the
VPN is established. But for the sake of it here are the routing tables
I can provide with you.

I like your Ping idea I will try that and repost.

Id copy it out of the RRAS but it's easier out of dos prompt. I'd have
to manually write the table out of RRAS since you cant select all and
copy. Rest assured I have checked and the tables do match.
