Stop loading Windows user profile

Hi,

1. Anybody know how to stop roaming user profile from loading?
2. Anybody know how to stop roaming user profile to be uploaded to the server?

I have a roaming profile set, so I can work using any PC. From time to time, however, I want to log in into a PC, and not load my roaming profile, I just want a default one. Haw can I stop loading roaming profile when login in into a domain? So far I log in with a separate account with no roaming profile set.

Also from time to time, I want to log off from a PC without roaming profile being uploaded to the server. Usually if I have to do this, I simply disconnect the PC from the network, but it has to be a better way.

I tried to do research on the net, and found heaps of information, but nothing to answer the particular questions.
