I am pretty sure that the problem is with the ISP.

I have two notebooks. One running WIN98 and the other WINXP.

Both cant connect with them but with another ISP it works fine.

Unfortunately, my connection to the ISP that LW works is dial-up that is why I really like the DSL connection to work. They also told me they are not blocking it.

Maybe they don't know that it is blocking it.
