Cannot add another connection

I am running Windows 2000 Server on a small 4 computer(and
1 printer) network with a DSL line.

When I try to "Make a New Connection" on "Network and Dial
Up Properties", only 2 options are open to me in
the "Network Connection Wizard": "Dial Up To The Internet"
and "Accept Incoming Connections", all the other options
are greyed out. I have updated my network adapter driver
and I am able to do everything else, go online, connect to
my network, etc.

This was working fine before I attempted to download SP4.
It really wreacked havoc on my system, but I uninstalled
it and everything is working okay, ,except this.

Please help. THanks.
