Hello,
It seems that AD is in sync with SEPM.
Were there any changes made in the AD?
Did you check if these Clients are actually Online or Offline?
There are 2 solutions for this issue as it relates to systems or sessions that have been re-imaged/reloaded.
Solution 1: Remove the client from SEPM if it is going to be rebuilt or re-imaged.
- If you know in advance that a group of systems are going to be re-imaged, you can remove those clients from the console ahead of time.
- If you have clients that are strictly running on virtual machines which are reloaded or re-imaged on a regular basis, create a separate client group for those clients. When it comes time to re-image them, they will be easier to locate when placed in their own group.
Solution 2: Configure SEPM to remove clients which have not connected within a specific number of days.
1. In the SEPM, go to the Admin page.
2. Select Domains.
3. Under Tasks, select Edit Domain Properties.
4. In the Edit Domain Properties window, on the default General tab, note the option to "Delete clients that have not connected for specified time."
Configuring a low value for this setting would clear up the duplicates more quickly.
It is important to consider clients that are offline over the weekend. Setting this value to 1 or 2 will likely cause all your clients to be removed after a weekend.
A recommended value for large enterprise environments would be 7 to 14 days.
Hope that helps!!
