My users are not able to access server drives when connected thru vpn. This has been working for years so it is not an installation issue. SBS is setup to be the RAS server. What I'm seeing is that the users are not getting DHCP during the session, they all have 169. addresses and no default gateway info. they do have dns defined pointing correctly at the server?
does anyone know where I find this setting, I've rebooted the Server, restarted the ip routing service, restarted DHCP service ?

If you are running SBS 2003 just run the Remote Access wizard in Server Management (Server Management>Internet & Email>Configure Remote Access).

Also, check in the DHCP console and make sure under "address leases" that you see some that assigned to "RAS".  These are the ones reserved for VPN users.

are you using the Connect to Small Business Server connection on the clients? Or did you manually create VPN connections?

Is it a remote office your're connecting or are these users all over the place? If it's a remote office, make sure that it's on a different subnet. For testing purposes, see if assigning a static address to one or two of the users results in connectivity. Go into the Users snap in in Server Management and right click to properties on one of the users affected. Go to the dial-in tab and assign a static ip address. Try to connect and see if it works. Then we can narrow down the real issue.

The users just connect to one office/server. I tried the static ip thru ADU&C, dialup , it didn't help.

Oddly this worked yesterday.. No updates or changes that I'm aware of ??? the proble was reported last night, users couldnt connect, after a reboot we can connect but can't access server , no dhcp being issued to the clients ?

So the users are connecting to SBS from the road, home or wherever right? You are NOT connecting from a remote office back to the SBS Server...?

Try this...From of the the computers trying to get in, go to your RWW site. Make sure you uncheck "I'm using a public or shared computer". Click "Download Connection Manager" on the right hand side and see what that does for you.

>>"The clients are All Windows XP, I manually created the clients "
You should be creating the client using the "create remote access disk" wizard or downloading from the RWW work site. This assures they have correct name resolution. The 169.254.x.x addresses indicate the DHCP service is not properly being applied to VPN clients, though those IP's will work if routing is configured. Better to fix the problem though.

If you use the SBS wizard as waynewilliams suggested it should configure the DHCP relay service for you. Are you sue you are using the "configure remote access wizard" in server management and not the the wizard in the RRAS console?
If it still doesn't work your best bet is to configure a static address pool as per the 10th step in the following link (should not be necessary with SBS, however...):

Good outline of the SBS method to establish the VPN:
http://www.lan-2-wan.com/SBS-VPN-instr.htm

Are the drive mappings done by IP or by name? If by name try pinging or mapping by IP. If that doesn't work make sure the local subnet from which the client is connecting is different that the corporates site. They must be different as pointed out by abatemc.
