If you changed a network adapter (NIC, modem, etc.) and ICS
stopped working you may be able to edit the Registry and avoid
a Win98SE reinstall. This tip may also work if you've
tried uninstalling and reinstalling ICS and it still won't work.

02/14/00If you can't get ICS to work and are going to try another
method, make sure you uninstall ICS before trying to install
any other sharing program or hardware solution. ICS installs

Windows to re-install ICS. Be sure to have your Win98SE CD handy,
although you may be able to skip installing files because the
uninstaller does not remove any/all files. Then again, this
is a stuck uninstall, so no guarantees!
If you've been trying to get ICS to work witih PPPoE,
you've probably discovered that it doesn't work very well. You
can try the tricks on this
page, but in general, ICS won't work with PPPoE. Several readers have reported using the AnalogX
proxy server instead, but as the name implies, it's
a proxy, not a NAT sharing program. If you want to use a NAT
sharing program, try Sybergen's

If you're running ICS and keep getting disconnected from
your cable or DSL BSP, you might try this registry
tweak contributed by Alfred Sham. He used it successfully
with BigPond.net in Australia, but it might work for
you, too. The tweak opens UDP port ranges 1024-5049
and 5050-5049 in ICS. If you're uncomfortable running
a registry tweak, you can use ICS
Configuration to do the same thing.
Trying to get an IPsec VPN connection working through
ICS? Forget it, since it's not supported.
Once ICS works correctly for the client
machine's browser, open mIRC.exe on the SERVER's machine.
It doesn't have to be connected to IRC, just running. The setting
for Identd should be "Enable Identd server" = checked,
and "Enable only when connecting" = blank.
mIRC on the SERVER acts as the Ident server for
the CLIENTS. So, when the CLIENT machine uses mIRC to connect
to DalNET, and DalNET polls port 113, the SERVER machine performs

1/15/01 Trouble connecting with PacBell DSL with EnterNet
1.4 on Windows 2000?
EnterNet creates a new network connection ("Local Area
Connection 2") in Control Panel which represents the PPPoE

that represents the NIC. Make sure you share the s"Local
Area Connection 2", and not the NIC.
