For the past 2 years I have had an issue on my network that
continues to grow in frequency. Random users (at random t
imes) lose authentication to the Ironport device. I can always
tell when this happens since the browser bar will suddenly show a web add
ress with random code but I do see Ironport in the
code. Originally I would have to have the user perfor
m a reboot in order to gain access again. I have since found that refreshing the c
omputers ip address (ipconfig /renew) will
re-establish authentication with the Ironport device. Or
iginally, this problem only occurred on 2 users machines, but over time it now seems t
o affect all my users. I have created a shortcut on the users desktops to run the
ip refresh command for them as a temporary fix, but would like to know if anyone else has h
ad this problem, if so how was it fixed?
