Okay, I have a user who noticed some bandwidth issues from anywhere he travels. I will paint the picture for you.

1. Server 2003 with RAS
2. Server is connected to Full T1
3. Client from home using MS VPN
4. Client is connected to Cable (10 meg down and 1 meg up)

When client does a speed test without VPN (from speakeasy site) the results are close to the given figures. When test is conducted with the VPN, the results are 7-800k Down and 400k Up. Same test at a hotel and same situtation.

I did the test from my home computer using the VPN and my results were in the range of my Cable speed. I don't understand what is going wrong on this user's laptop. The configuration of the VPN client were the same. I went through two firewalls where the user did not.

I did check the MTU on the laptop which is not set (default)  per DrTCP. I just rebuilt the laptop last week.

I would appreciate all the help.

Thank You,

Habib

Suspect users speed test is going through the VPN tunnel  to the office and from there to the speed test site.

That worked, the gateway worked. Now, I am getting Outlook connection errors.

You want it all eh !  :-)
It is likely a DNS issue. Outlook was resolving the name through the tunnel, but now it may be trying to resolve the same names via the Internet. If your users always access Outlook from the LAN or VPN you can add an entry in the Hosts file on the PC, located in:
%windir%\system32\drivers\etc\hosts
add a line for your mail server such as
192.168.123.123        mailserver.mydomain.abc
A couple of rules for hosts files:
-save with no file extension
-the spaces are tabs
-at the end of each line hit return (carriage return) before saving

This should tell Outlook how to resolve the name correctly.
