Lose connection to mapped drives when connected to VPN

I have just taken over an account with a Sonic Wall TZ100. Our problem is in the VPN setup. We can connect wonderfully with the Global VPN Client but when we do, we lose connectivity to our local mapped drives and ability to print locally until we log off the VPN. I am sure it is a setting we are missing.
Can you help us?
This is how we use the VPN. We connect the VPN to the remote server, then remote desktop to our accounting software. We then would like to print locally and toggle back and forth between desktops to the local machine without logging off of the VPN to do work locally. Unfortunatly, when connected to the VPN, all of our local mapped drives get disconnected. We also lose our internet locally.

Are they still listed only empty, or are they just missing? Also does anything appear in the event viewer?

They are still listed but have a red X and arent available. I will have to look at the event viewer. Another thing is that if we try to print, it just stays in the que until we log off and then it will print.

Using offline files? If so try disabling them.

I do not know the Global VPN client but I can explain what's going on.  On connecting to the VPN, you are setting up a "full tunnel" connection where you are using the default gateway defined on the VPN server.

In order to see your local network including mapped drives and local intranet, etc, you need a "split tunnel" where you use the local default gateway.  Any internet access will then be through your local internet connection rather than through the remote internet connection when you use a Full Tunnel.

Perhaps you can look in the client setup manual for such things as "default gateway" or "default route" or "split tunnel" and see if you can work out how to use the local default gateway instead of the one set by the server.

Is it that they disappear after a certain amount of time?  There are firewall settings to adjust the inactive TCP timeout.  We had to adjust this for applications like SAP where a user will login, then walk away for 20 minutes.  The default inactivity is 15 minutes.

No the drives are not available right away after connecting. I am leaning towards losip's answer as far as the "split tunnel" however I see nothing in the client setup that allows me to use that option.

Can you access the shares via \\server\share ?   If so, just set the globalvpn client to process the login script in the preferences.

No, I tried that. No local network access at all.

What is the local network and subnet?   What is the remote network and subnet?  Are the IP's on the same subnet?

getzjdCommented:
In other words, what are the DHCP addresses being dished out on the remote site of the globalVPN?  Sounds like they may be the same as your local IP scheme

One is 10.10.2.x and the other is 10.10.1.x.

i assume the subnets are not 255.255.0.0 ..

One last thing, then I am out of ideas.  Look at your GlobalVPN client settings on the computers.    You dont have "set default route as this connection" checked or any other odd setting do you?

http://help.mysonicwall.com/sw/eng/general/ui1/6600/VPN/GroupVPN_IKE_Preshared_Secret.htm

While you are connected to the VPN, what happens if you ping, by IP, a machine on your local network?  If it goes nowhere, does an access denied event pop up in the log of the remove sonicwall?

Oops i meant check that on the Sonicwall side of it...

for the client settings check

Peer Defined Network Settings - Defines the status of Tunnel All support. These settings are
controlled at the SonicWALL VPN gateway.
Other traffic allowed - If enabled, your computer can access the local network or Internet
connection while the VPN connection is active.

"set default route as this connection"  was the answer. I unchecked that and it worked. Thanks sooooo much. I am not familiar with SonicWall. I use the Watchguards so this is much different.
Great job.
