SEP 11.0.7200.1147 NTP blocks outgoing http traffic
a few weeks ago we installed the SEPM version 11.0 RU7 MP2 and updated round about 100 Vista and Windows 7 (64Bit) clients. After a successful testing phase (no incidents recognized) we updated nearly 1000 clients (mostly Windows 7 64 Bit) on a different Managementserver, which also was updated to 11.0 RU7 MP2.
Now, after a few weeks in prdouction we have only a few clients that have problems with the Symantec firewall (NTP). After a while the firewall modul starts blocking http traffic, https still working. Furthermore the firewall blocks only public IP adresses via http, I can still reach private adresses (i.e. my routera at home).
Any ideas where I can start my investigation in this bug (?) or did someone expected the sam issues ?
My second question : How can I downgrade these clients within the SEPM console ?
