Vista - Network Access: Limited Connectivity

After upgrading Vista Ultimate to SP1 two days ago, I noticed on the Taskbar
that I'm getting a yellow Caution symbol on top of the Network Icon.

My internet connection seems to be working correctly.

I've tried resetting my Linksys router, removed and reinstalled Norton
Internet Security 2008, upgraded my NIC drivers, (I'm using an ASUS P5K
Deluxe motherboard with built-in networking.), tried the Network repair
options, etc.

This problem did not occur before the upgrade. Any suggestions?

do you have this issue when Norton is uninstalled?

Hi Barb:

Thanks for your response.

Yes the issue remains the same whether Norton is installed or not.

I would also like to indicate that when I go into the Network & Sharing
Center, a yellow caution symbol appears between the My Computer icon and the
Network icon; a red X appears between the Network icon and the Internet icon.

Hi Barb:

I'm actually working direct with Microsoft Support on this problem. They
told me that they first became aware of this problem about a week ago and
that they were still working on a fix.

We spent a few hours yesterday working on the problem and discovered that
SP1 and Norton Internet Security 2008 weren't getting along network wise and
that even by removing NIS, the problem remained. Apparently Norton was
making a Registry change to the Administrator's Permissions which was locking
out most of the outbound ports. (That doesn't make any sense to me; that was
the explanation given to me by the Tech Rep.)

Here's what we did which partially fixed the problem: The rep had me create
a Password under my User Account. (Since I'm the only user of this computer,
I've always run as an Administrator without a password.) We then executed a
CMD.EXE and entered the following at the C:/ prompt: Net localgroup
"Administrators" "NT Authority\Local Service" /add

We rebooted and no more yellow caution symbol. I was now able to
communicate with my D-Link Media Server using D-Link's server software, but I
was unable to communicate with the Media Server using Window's Media Player's
Server which is the Server Software I like to use. We also discovered that
if I removed the Password from my User Account, the whole problem re-occured,
yellow caution symbol was back.

So that's where we stand as of now. I've been contacted by Microsoft
Engineers twice today, and that they assured me that we'd have a solution
later in the day. I was also told that Symantec was aware of this problem
and that they were working on a fix for NIS.

I'll keep you and the community updated.
