First off I should inform you that this may not be a Windows 7 problem, but it might be. I am not sure where exactly to place this.
Configuration: Firewall in use on an enterprise network using a Class A network, with end users on a Windows 7 machine.
A single user in an enterprise environment loses access to external network resources periodically for 5 - 20 minutes. This problem occurs randomly.
Problem occurs only for this one user, others on other workstations function fine
Problem occurs across multiple computers, but always this one user
This user does NOT use a roaming profile
Problem occurs on IE
Problem occurs on Chrome
Problem Occurs on Firefox
Resetting all default settings in the browsers does not resolve the problem
Adjusting the TLS and SSL settings does not resolve the problem
The Cat5 from her computer to the floor jack was replaced (moot point since it follows her on different systems)
The Cat5 cable from the patch panel to the switch was replaced (same as above)
Users profile was completely removed and rebuilt on system without success
Deleting the users bookmarks in IE solved the problem for one week, but it returned (may not be related)
PING traffic to the Intranet services on the corporate network function and replies are received during outage
PING traffic does NOT succeed when hitting google at 220.127.116.11 or 18.104.22.168 during outage
PING traffic does not succeed to any known external resource during outage
Admins can remote computer during outage (but they are on intranet, but a different subnet in a different city/state)
There are no known software conflicts, and problem still occurs when only the browser is in use
Problem occurs across multiple websites
Computer was replaced and the same result occurs
Computer is fully updated with MS updates
Does anyone have any other possible cause or solution for this behavior?
