Scripts to identify if the compartmentid in endpoint info and corresponding namespace info is different.

@@ -0,0 +1,6 @@
+The script extracts the namespaceId and compartmentId from the endpoint information. It then validates the compartmentId against the namespace details. If any anomalies are detected, HNS and TCP/IP traces are captured, along with Windows log collection.
+
+To run the script, open a PowerShell window and run the following command: 
+ PS> .\invalidCompartment.ps1
+
+ Or, we can run the scripts under hostprocess daemonset containers using invalidCompartment.yaml
