HI,

Configure SEPM to remove clients which have not connected within a specific number of days.

1. Open SEPM and select the Admin panel.
2. Click on Servers
3. Right click on the Site where your management servers are located and choose Edit Properties
4. Check "Delete Clients that have not connected for __ Days"
5. Enter a value for Days.
6. Click OK.

Is the SEP Client is still installed on those 100 machines? If yes then you can delete those with the help of above post but it will start reflecting in SEPM once its reports back. So better Uninstall those 100 macihes using AD Policy or other Application management Packages. Or manually

Also, don't forget that the "Delete clients that have not connected..." option moved to the Domain Properties in sep12.1RU1.

You can also just highlight the clients in the SEPM Console and right-click -> Delete them, but as the above post mentions, if these are active clients the record will be recreated when they check in.

Why are you trying to remove these clients?  Are they duplicates?

Hi,

There is not any script or tool by Symantec.

You will have to tweak settings in SEPM.

Please check this video, it will guide you step by step.

I dont understand why do u want to delete clients.

even if you delete clients and if they have valid Sylink.xml they still report to your sepm.

if you want to delete clients which care not connected to your sepm , well there is default 30 days.

if you have uninstalled clients and want to clean it ASAP then set this setting for 1 day

"Delete Clients that have not connected for __ Days"
