Bit of a wired one here.
Running Windows 7 VDI with vWorkspace 8 and use thinshell to connect to the hyper-v machines
I have created some new users in AD but when i log onto the VDI the internet doesnt for for the first 3 minutes of the session and gives a readresponce() error. After 3 minutes it jumps into life and everything works until the users logs off. When they log on again they are back to square 1.
Existing users do not have this problem. However, if I delete the metaprofile of an existing user then they DO get this problem and cannot access the internet for around 2-3 minutes.
We use a proxy server and up to today creating new users hasn't been a problem
