Hello,
I have an issue that not all clients are updated with the latest proactive threat definitions (currently it should be 2010-01-25 rev. 019 for proactive threat).
We use a variety of SEP 11 MR4 and MR5 clients (not all are already updated to MR5), and the problem also existed with MR4 only. My installation partner told me that an upgrade to MR5 would solve the issue, but even MR5 (11.0.5002.333) clients are not always updated with the latest proactive threat definition.
From the 296 clients we have (today):
* 140 clients with version 2010-01-25 rev.019 (= latest).
* 101 clients with version 2009-12-31 rev.020
Most users reboot their client every day (shutdown at end of working day), but this does not help.
We have a mix of Win2000 (SP4) and WinXP (SP2 and SP3) clients, but the issue is not related to 1 version. For example: my machine (Win XP SP3) had the version 2009-12-31 rev.020. After rebooting the version of proactive threat stayed the same (there are no erros in the event viewer of the machine).
The next day (today) it still was the same version. In the afternoon I DISABLED my network card and after 5 seconds I enabled my network card again. And (only then) the proactive threat definition was updated to the latest version.
