Odd connection icon after SP 2

Archived from groups: microsoft.public.windowsxp.basics (More info?)

Hi

I've just installed SP 2 on the PCs of a small peer to peer network. The
network connection icon at the right end of the taskbars now has an
exclamation mark on it. The Support tab of the Local Connection Status
properties dialog says, "Limited or no connectivity. This problem occurred
because the network did not assign a network address to the computer."

What does this mean? The LAN seems to be working fine at 100 MB/S just as
before.

Thanks in advance.
