Just out of curiosity, do the machines loose connectivity only after they a=
re added to the domain? BTW, our group policy disables the Windows built in=
firewall an all our machines, with no ill effects.

Subject: Windows 7/2008 not connecting to network...
We have a strange issue going on our campus that's causing our Windows 7 co=
mputers 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 Win=
dows Updates were installed on those computers. As a result, the Windows Fi=
rewall services and its dependency services all got turned off on those com=
puters 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 cau=
se 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 th=
e aforementioned Windows Updates were installed. I have a feeling that the =
problem lies with how the computers are authenticating to the domain, but c=
an'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 th=
e 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 s=
uggest?
