Ironport Web authentication drops randomly

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?

Are you using IP Surrogate or Cookie to keep track of authenticated user sessions? Investigate the timeout values of the authentication setting.
