RE: TR: TR: [squid-users] https analyze, squid rpc proxy to rpc proxy ii6 exchange2007 with ntlm

Back with my windows7 test, and failed ... I dunno exactly why, but It times
out with a "server is is unavailable".

In my IIS httperr log I have :

HTTP/1.1 RPC_IN_DATA /rpc/rpcproxy.dll?xx.xx.fr:6004 400 1 BadRequest
DefaultAppPool
HTTP/1.1 RPC_IN_DATA /rpc/rpcproxy.dll?xx.xx.fr:6001 400 1
Connection_Dropped DefaultAppPool

Ok with XP, not with windows7 and vista I guess

Can you help me with this ?
Thx

Clem

For infos, I'm using squid 3.2016 beta, exchange 2007 sp3 and a test client
on XP, I'll test a client on windows7.

No config for blackberry devices, they don't use activesync but the
connection to blackberry server directly connected to our exchange.
