We use small business suit 6. Everything is fine when workstations use
window 2000. However, when changed to Windows XP, one problem happened.
We have to type user name and password for board manager authentication to
access Internet when turning the workstation first time to access Internet
explorer. After that, no this kind of board manager autication
requirement. Every time, when shut the computer down, and turn it on ,
and the problem happened again.

In windows 2000, the kind of problem happen not quite often. It is fine.
