If you have ever had to support, or use an Exchange server that uses RAS to send and retrieve email, and is used as a workstation by users (I can see people cringing, but I see this in a lot of small sites and small businesses) you will know the frustration of loosing your connection every time you log on as a different user.
To make matters worse, half the time the problem with these types of sites, is that there actual connection problems.
When you log on as a different user in NT4.0, it terminates the connection. Users of VPN’s will have come across this problem as well.
To resolve this problem, it’s a simple registry entry.
HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon, add the value entry KeepRasConnections: REG_SZ: 1, and reboot the server
This value is not entered by default. Now that’s resolved, you can concentrate on more important things, such as how to convince management to buy more PC’s so the users don’t use the server as a workstation

To block all of napster’s sites set the firewall to disallow the following IP blocks:
22.214.171.124 — 255
126.96.36.199 – 255
Out of the box napster uses TCP ports 6699, 7777, 8875, 8888

You can reconfigure Proxy Server to only allow a specific workstation to use the internet by changing the LAT to only include the IP of that specified workstation.
To do this, firstly give the chosen workstation a fixed IP address, and exclude it from the DHCP scope. Then go into the Proxy MMC, drill down to the Web Proxy and go to properties. Select the “Local Address Table” button, then type in the workstations IP address for the From and To sections and add it to the LAT. Remove all other entries in the LAT, give the workstation the fixed IP address mentioned above, and restart proxy.
You may also want to change the permissions to remove all access control, therefore making the workstations IP address the only limit to users surfing the web.

Proxy Server does not support reverse hosting of socket level applications and therefore can not provide this functionality by default. A product that can provide this is Surrogate Sockets. http://www.edu-tec.com/surrogatesocket/

Microsoft have written a KB article on this one – Q234203 contains 3 options but basically you need to expand the wspcpl32.cp_ file to wspcpl32.cpl from it’s server based location and copy it into the windows\system or winnt\system32 folder on the workstation.
