> Ok,
Talking today to Bezeqint, they just said I need to contact Hot.
Well Yesterday Hot didn't want to solve this problem for me.
Today the representative of Bezeqint called Hot, and a very good tech guy
answered.
He without to many questions tried to change my connection to dialer, so my
computer will take IP 172...
Then he changed it to without dialer and my computer did take 84... IP.
I have left my dhcp service restarting in a loop every 1 minute. Hope this
will not cause a problem today.

So the solution was:
Reset my connection to dialer, then reset it back to DHCP connection.

After that the representative saw that last week she did the same thing,
which solved the problem.
Now the question is why this happens?
At Hot he said that he will call the sysadmins that responsible for this
server. Hope he will do that.

Do any one of you knows what can cause this problem at Hot servers ?

Regards,
Kfir
