Do you have a desktop firewall installed (e.g. ZoneAlarm)? If yes,
then try disabling it (you won't be able to deinstall ZoneAlarm
without corrupting your windows installation - believe me, I've
tried).
ZoneAlarm (and some other desktop firewalls) replace the OpenSSL
library with their own (and most of them do it wrong) to check even
encrypted network traffic. Since most of these firewalls have severe
issues and don't follow the OpenSSL rules by putting their own
(incompatible) version of the dll in the system directory, TSVN now
does some more checking to ensure it uses the one we ship with TSVN
and not one which some stupid program installed in the system dir.
My guess is that in such a case the desktop firewall still tries to
check the network traffic but can't anymore - it either tries too long
a time until the connection times out, or simply rejects the
connection because it doesn't know what it is for.
