Why does it take so long to login and logout using a CS account? – CS accounts have a roaming profile.
Information Services accounts do not. When you login, your roaming profile is downloaded from the profile server, and when you logout the local copy is compared with the profile server’s copy and changes are uploaded to the profile server. As your roaming profile grows in size, the login/logout time will increase. It is therefore in your interests to keep your roaming profile as small as possible, by leaving nothing much (except perhaps a few shortcuts) on your desktop and saving files on H:, as suggested above. The huge majority of slow login/logout problems are the result of overuse of roaming-profile space.
