Created: 22 Jan 2008 • Updated: 21 May 2010 | 5 comments

I know Proactive Threat Protection is not supported on server 2003 but i am having problem that Proactive Threat Protection Remains Disabled on Clients and i have to manually enable it everytime from Domain Admin Account. Proactive Threat Protection is updating on clients but only problem is with enabling it. It gets disbled on reboot on some clients even after enabling it from admin account.

PTS is actually not supported on any Windows Server OS. Are these servers or workstations you're having trouble enabling PTS on? One thing to check is in your Antivirus and Antispyware policy under the Truscan section, make sure you have 'Scan for trojans and worms' or 'Scan for keyloggers' (or both) checked.
Hope this helps.

I have the same problem on a stand alone PC running XP SP2 with SEP 11.0.1000.1375

Has happened previously and fixed itself after a few days but this is hardly what you would expect from a leader in virus protection.

Are there any fixes or patches that can be implemented to get SEP working again?

Thanks in advance,

Did u by chance upgrade or was it a fresh install? And prior to the upgrade, did the clients have the Truscan (PTP) feature installed?

IMO, with all the troubles it's caused us, frankly, I'd leave it disabled or gone!

I can PROVE where the PTP piece slows Word files to a crawl, specifically the application and device control part.

I can knock from 30 seconds to 2 minutes off of file save times by unchecking that in the console.

I've been 6 weeks testing, have a VERY Expensive Microsoft support call escelated to the top (costing us a fortune) only to find the problems were with PTP in SEP MR4.
