2 PC's on local network how to connect both to SBS2003 via 1 VPN and allow lan and wan


I have some problems with a SBS vpn setup. Partly caused by a remote user fiddling so I can't be 100% sure of the current configuration as I can't get to remote location for a while. Essentially I have:

SBS2003 server setup up for VPN access (working)
Remote user with 2 PC's connected at other end via router.

PCs run XP pro.

1 PC was connected to the server physically originally and has the domain set to the sbs2003 domain.
1 PC has never been near the server and is set to a local workgroup.

Both PCS can connect to the network over VPN, get email access web and maps via VPN connection BUT not both at the same time. The users of the 2 PCs have separate static addresses for VPN in there user records on the server.

Also they cannot browse each others PC locally (as not on same domain) and hence one cannot access the printer on the other.

What I need to know is how this should be setup so I can rectify the fiddling and get this to work.

To sum up.

2 remote XP Pro PCS need to connect via VPN to the SBS server via 1 router at the same time (different users) and also be able to locally share drives and printers.

Thanks in advance for the help.

Have the PCs ever worked together before? Just a thought, it could be that you need to enable a feature called VPN ALG in your router. As far as I'm aware, it allows more than one VPN connection to pass through the router's firewall at the same time.

Both PCs have worked indepently, one was bought and added after I had been at the remote location. Never heard of VPN ALG, maybe that router doesn't support it. I will find out the router specs.

On following this up I strongly suspect that the router is way too cheap to have more than one vpn channel so that is probably one part of the question answered. Can anyone suggest a wireless router with dual VPN?

I'm really not sure what the problem is here... but you should have no issues connecting TWO PC's at a remote location via VPN to your SBS.  It really doesn't matter whether the router can handle more than one VPN channel because you shouldn't be using the router as your VPN End-Point... that's taken care of by the SBS.  Then there's really no limit on the amount of connections.

The router just needs to be able to handle GRE Protocol 47 (PPTP Passthrough).  

I don't know why you configured a static IP address for the VPN connections, but you really should just use the Small Business Connection Manager as your VPN Client.  (Downloaded from the SBS's Remote Web Workplace main menu -- see  http://sbsurl.com/rww).  This will handle everything for you.

Then, are you saying you want to join the other PC to the domain? If you do, you cannot join a PC to the domain using connectcomputer over a VPN connection.  However there is a workaround:  http://www.smallbizserver.net/tabid/266/ArticleType/ArticleView/ArticleID/83/Default.aspx

If you choose not to join the PC to the domain, then change it's WORKGROUP to match the domain's NetBIOS name and create a local account with the same username/password as the domain user who is assigned to that PC.  Also create a local username/password to match the user of the OTHER PC.  This will allow sharing of files and printers between the two computers.

Workaround worked nicely. Thanks
