network connection problems.

[Guest]

there is a laptop here at work that the Internet connections are slow. Some
times you can get to a site and sometimes the “Page not found†DNS error is
displayed even for the same site if you refresh.

Even our default company intranet page will get the error or not come up all
the way.

It is also extremely slow to display drives in My Computer….even the c: drive
All settings seem correct. Good IP address, DNS and WINS servers are correct.
I can ping the DNS and WINS server just fine.

This happens when connected to the company network or if the user is in a
hotel using wireless or wired connection.

Any suggestions are appreciated.
