I have 4 sites that I connect via a pptp connection VPN. I had this working without issue for the past year. I then reinstalled my computer for other reasons and now that I have a fresh install of xp sp2 on my computer, I can still connect to the VPN's, but here is what is now happening.
When I connect to the main VPN (this is the one I use to get my outlook email as I am off-site) I can access all resources as I would expect. I then want to connect another site (totally unrelated to the first site) I am able to connect and access resources on that remote VPN. When I do that, I lose my connection in Outlook. I can still ping the mail server, which is again on the first VPN, but I can no longer connect. If I disconnect the second VPN, it instantly connects again. I also lose my connection to our DMZ at my current location, which is not apart of any of the VPN's. None of this happened before I reinstalled my connection. I could connect 2 separate pptp VPN's and have full access to all 3 sites with no interruption.
Any ideas what may have happened here? For whatever reason, it seems that the routing is being affected when I connect to a second pptp.
