Windows 7 connection issue

i newly update the computer to win7 and found some problem with connection

here is the situation…

a new, fresh win7

since it is a company computer

i need to set an admin & a regular user

while i can use spark perfectly fine in admin account

the regular account does not connect at all with the same setting

i tried a few more XMPP client and they all return the same result

good in admin account

stuck in regular account

it is pretty much some sort of access right or service is disabled in the regular account?

how could i locate the issue and fix it out…? thanks in advance

fixed, UAC issue, thanks all
