Networks

Could the key to this be the Network Icon, Protocols, TCP/IP, ADVANCED. PPTP check box down at the bottom?
Either all clients should have it cleared, or all should have it checked, a mixture could produce the symptoms you describe.

If you installed PPTP, you must apply service pack, did you?
PPTP is just a protocol, and should have that kind of impact on your network. Your problem might be other than PPTP and adding it to the server tickled the real one. If you didn't yet, re-apply your SP.
Also, should you overcome this problem, when setting up the VPN, make sure you reserve a range in DHCP for the many VPN channels you'll be creating.

Good luck!

I think what you're sayin' is: "I have two LANs, the are remote to each other and they are connected via a PPTP tunnel on a DSL carrier" or maybe you only have one PC connecting remotely via the PPTP tunnel.

If you have a PPTP tunnel on a server,rememebr that something COULD be routing your local traffic over the DSL line and staying there awhile until it's sent back. Maybe you should check out your routes...

when you use proxy you can't use pptp. reason is b/c Network Address Translation NAT won't route the correct headers.

The PPTP service running on the client takes an IP packet and adds an additional header to the packet, encapsulating the original packet. The packet is sent back out to the Internet to the wrong machine and will be ultimately discarded.

DSL is using PPOE as the protocol encapsulation. Use a dsl router with nat and do away with the proxy server. they are about $350. call swbell. 888-SWBDSL1

Don't get me wrong, DSL does work with proxy and nat I have the same setup as you at home. But not with pptp. PPTP was not designed to be behind nat.

For those users that eventually got through, who knows! They problably were looking at cached files from the proxy server.

if you need more info e-mail me.
hope this helps
