Type "ipconfig /renew" at a command line. If you get an error about
something not being a socket or not being able to initialize a provider then
read on.
----------------------
I have traced several of these problems to improperly configured winsock
LSPs. Run "winmsd" and
go to Components/Network/Protocol. Look at the names in the list, anything
with "MSAFD" in it
or the "RSVP xxx Service Provider" should be fine. Anything else is
suspect, and uninstalling
the owning program might help.
If that fails or your provider list is empty, you may need to rebuild the
catalog from scratch.
The following instructions will rebuild your catalog for TCP/IP. If you are
using any other
transports (If you don't know, then you probably aren't) then you will have
to reinstall them as
well.
1. Backup and delete the following registry keys
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
2. Reboot
3. Go to the network connections folder, right click the icon for your
network connection, and
select properties.
4. Click install, choose "protocol", and click "add..."
5. Click "Have Disk...", enter "\windows\inf", click OK
6. Select "Internet Protocol (TCP/IP), click OK
7. When the process in complete, reboot
