Just a thought from a completely different direction, maybe it could
help, also involving Windows7 and lack of connectivity after updates: I
had one poor student sent to me, he had completely lost network &
Internet connectivity after updating Windows recently. None of the
student techs nor the best staff desktop tech had any more ideas. What
finally got him going again, was to
=20
1) disable/subtract IPv6 from the NIC's properties
2) in Management > Services, stop the IP Helper Service (related to
IPv6) and change its Startup Type to Disabled.
=20
Everything worked great after that!

Subject: Windows 7/2008 not connecting to network...
=20
We have a strange issue going on our campus that's causing our Windows 7
computers and Windows 2008 servers to completely lose network
connectivity.=20
=20
This is only happening to computers that are connected to the domain.=20
=20
The issue seems to have started a few weeks ago after the last round of
Windows Updates were installed on those computers. As a result, the
Windows Firewall services and its dependency services all got turned off
on those computers and can't be re-enabled either. Also, RDP access to
those computers won't work either. I suspected a group policy of some
sort might be the cause but we use little to no group policy
administration on our campus at all. Upon further investigation, we
found that there seems to be some cause to this due to some registry
permissions that seemed to have changed after the aforementioned Windows
Updates were installed. I have a feeling that the problem lies with how
the computers are authenticating to the domain, but can't confirm that
prognosis.
=20
I've tried everything to fix this issue from changing group policy
settings, to removing/re-adding the computers to the domain. Nothing
seems to have worked permanently or at least completely. We have managed
to do some on the spot MacGyvering to fix the issue (i.e. manually
applying administrative permissions to certain keys in the registry on
those computers as suggested by a few online articles) but they are
temporary band-aids at best.=20
=20
Has anyone else run into this? Any permanent fixes/solutions that you
can suggest?
