My workplace has VPN and it works great for me in Parallels Windows XP and Bootcamp Windows Vista. However, with the same config, I can't get it to work in Snow Leopard. I don't know what type of server they are using, but PPTP works for Windows. Any ideas why it may work for Windows and not OS X?
Update: I should also mention that at one point it did work. I couldn't tell you if anything changed at the server between when it did work and when it stopped.
More information: I can connect just fine, but I can't access any resources. I try to ping a known internal IP address and the destination can't be reached.

I've had trouble with VPN before on my setup. I fixed my problem, but I had to do a couple of weird things first. Could you tell me more about your settings?
Under System > Preferences > Advanced...
Under (tab) DNS > DNS Servers: Do you have your DNS servers set?
a. If so, are they something like 192.168.0.2 and 192.168.0.4? You may need to change your home router's IP address if so.
Under (tab) DNS > Search Domains: do you have a search domain set? ie. domain.local
I hope changing those settings helps. If not let me know and I'll try to help. VPN has been enormously frustrating for me in the past.
