Endpoint Protection

 I have installed SEP MR4 MP2 in Windows XP SP3.

Since we will deploy NAP in out network, I enabled Security center. On some computer, I find that windows security center detect SEP is cloesed. but SEP is working fine. what shall I do ?

As far as NAP is concerned we have a product namely SNAC which is compatible. If the SEP installation is working fine then crosscheck it with other machines who do not give this error.

SEP is alright, this maybe an issue with WMI repository unable to process OR corrupt

There are ways to clean the WMI repository

One of which I use is:

1. Stop Windows Management Instrumentation(WMI) service。
2. Delete all the files in C:\windows\system32\wbem\Repository folder
3. Start Windows Management Instrumentation(WMI) service or reboot computer.

Make sure all your clients are also on MR4MP2 or MR5/RU5

If I restart SEP service, It will ok.

but every day i find the same issue on different  computers ! 

 Nelson:
 Can you pls. elaborate little bit more on this issue. do you think you can generate logs and share us some more info? Are you running liveupdate manually. Do you think you have a reproducible scenario? What is the NAP policy you are using?

restarting SEP works, does that mean SEP service is stopped (SMC, rtvscan.exe)?

 I've already try this, but it didn't work in some computers.

En, only "net stop "symantec antivirus"" and "net start "symantec antivirus""
