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.
This is only happening to computers that are connected to the domain.
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.
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.
Has anyone else run into this? Any permanent fixes/solutions that you can
suggest?
regards,
