I have the same exact problem. For about a year now (yes, I've been
trying to figure this out for a year), I have been unable to access
Passport.NET sites from any client behind my Windows 2000 Advanced
server (even Linux clients). Recently, within the last 4 or 5 months, I
have been unable to access about 45% of other sites, including secure
and non-secure sites (one in particular, Discovercard.com

).
I accidentally deleted the Internal interface, but from what I have
read, that really doesn't matter unless you are using VPN / NAT.
However, having said that, I am experiencing the problem originally
posted. To reset my RRAS server, I right-clicked my server name in the
MMC and chose Disable Routing and Remote Access and get the warning
that doing so would erase my current configuration...blah blah blah,
yeah yeah yeah...and proceeded. According to MS, I should be able to
then right click my server name in the MMC and choose Configure and
Enable Routing and Remote Access, however, it is a disabled context
menu item. (BTW, I am running SP4).
TO KIRANGHAG: Is this what happened to you as far as RRAS is concerned
and not being able to "reset" it?
TO EVERYONE ELSE: Has anyone had this happen and know of a solution??
TIA
