FC10 VPN Setup to Windows PPTP using Network Manager
I was going through this for a couple of hours as I was trying to configure FC10 (moved from gentoo [for now]) and NetworkManager to connect to my office's VPN server running on Windows(R) ISA server.

I tried a variety of methods and configurations but I keep getting errors of the sort

Authentication errors, but the issue was WHY?

Ends up, and this may not apply to you, but it definitely applies to me.

My office is using Windows ISA server (200x version I would think)

So, in Network Manager, there are 3 option boxes

Username
Password
Domain

so, I happily added

Username : lotso
Password : lotso's password
domain : lotso's windows domain

ended up I get those errors above.!!

......
.....
2 hours later and MUCH googling
.....
....

I tried
Username : lotso's windows domain\lotso
password : lotso's password
domain :

and it WORKED!!


Ideosyncracies!!

on the other hand, this is _not_ a bug w/ NM or PPTP, seems like per digitalwound, his one works fine w/ those 3 options
