my question is for the Prof people only
How to allow over 2 pcs to work using the same user account and or with one condition
only one user can work at the time
same like msn messenger user login and AOL
lol - so if nobody considers himself a professional, you just eliminated any possibility of help 
And if you wanna professional answer, make professional questions - what user accounts? hotspot? ppp?
My definition of a “Professional” is someone who gets paid for services rendered.
That means its time to pay up for your answer!
Kidding.
really, you need to post more info.
both hotspot & ppp users of course
comon guys the question is for pro people only, they will have the answer without wasting time.
I’m not a prof !!!
anyhow if u are using hotspot just remove the cookie and give the 2 PC same name & pass
one will work till timeout then the second can log in
what about them using the same account info with a small diff
first letter in the second account is capitalized
ho ho ho
