we have Timeout Problems on Windows 7, either sometimes browsing on network shares, but really reproducable using sqlplus (Oracle Client).
If we connect to a Database in the command window using sqlplus several times, the first two connects
issuing "sqlplus username/passwort@db" work find, the third takes up to 30 seconds to connect.
On XP or Vista we do not see such a behaviour, sqlplus connects always fast and fine.
The Problem is a Win7 Problem and occurs in 32bit Env and 64 bit Env.
Does anybody has an Idea ?
