xp 有兩個問題,吾知點解決!

xp has 2 accounts, acct1(administrators right) and acct2(users right).

Q1. issue with ie accessing intranet ip
1.1 acct1 is able to access router and login by ip address
1.2 acct2 is able to ping ip address successfully, but unable to access router in ie(even tested with given administrators right)

Q2. issue with internet speed
2.1 acct1 has fast internet access speed, watching atnext.com.hk clip and youtube is smooth
2.2 acct2 is very slow, watching online clip is laggy
(but both tested with ofta with normal fast internet speed)

thx.
