try these step

Check in the registry (HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings) those keys

2. Change ProxyEnable to 0
3. Delete ProxyServer key

These settings are also cached in Hex format in the following location: HKU\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections

If DefaultConnectionSettings and SavedLegacySettings are present, they will re-populate the proxy settings. If they are NOT present, they will be generated with the current proxy settings. This can cause issues if the customer tries to alter just "HKU\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable" without also purging DefaultConnectionSettings/SavedLegacySettings before a reboot.

As per your question you want to find system not connect SEPM server. ?

first of you can use You can use unmanged Detector and find those system..

What does it mean to set a client as an Unmanaged Detector?

Unmanaged Detector in SEPM


If you have already list of SEPM client.

Kindly verify..

Check are you able Telnet SEP Client to SEPM server Port no (80,8014)?

Check Sep Client  help&support-->troubleshooting -> Server Name ?

Check SEP Client Policy are Showing correct or not ?

and also provide sylink logs ?

Thanks In Advance

There are two weekly scheduled reports & seven pre-defined notifications configured by Symantec.

Schedule Reports: SEPM --> Reports --> Scheduled Reports

Notification location:

SEPM--> Monitors--> Notifications --> View Notifications --> Notifications Conditions

Those reports are commonly required by Company System admin's so Symantec is giving it as a pre-defined.

Are you receiving those reports? Are they providing fruitful information?

Also check links given by others for further troubleshooting.
