hello,
I am having a problem where sometimes ironport block everything,
we have opened a case and the support told us to bypass authentication for the following user agent
Microsoft NCSI
Microsoft-CryptoAPI
Windows-Update-Agent
jupdate <-- http://javadl-esd.sun.com/update/1.6.0/1.6.0_26-b03.xml
MSDW <-- http://watson.microsoft.com/StageOne/Generic/PnPDevic...
Gp
Microsoft BITS
Google Update/1.3.21.79;winhttp;cup <-- http://tools.google.com/service/update2?w=<some_long_random_string>
ent-shasta-rrs.symantec.com:443
liveupdate.symantecliveupdate.com
this solution helped us for a month, then we are having the same problem,
do someone have the same behavior?
