IKE auditing is turned on by default. If auditing of logon events is turned on, IKE posts negotiation results in the Security Event log. Once policies have been assigned and are work ing, you can turn this feature off by adding the DisableIKEAudits value and setting it to 1. You should then stop and start the IPSec service. The value should be created at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Audit.

You can also increase the amount of information logged to the Security Event log by asking for per packet drop events. You perform this task by increasing the audit level to 7. You can either use Netsh or set the following Registry key to a value of 7: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IPSec\EnableDiagnostics. Regardless of the method you use, you must restart the computer for the changes to take effect.

Troubleshooting Network Protocol Security 11-73
If the policy is different from the one you were expecting, which GPO is respon sible To find out, you can use the Netsh Ipsec Static Show Gpoassignedpolicy command or the Resultant Set Of Policy snap-in. What are the details of the policy Use the Netsh Ipsec Static Show All command. You are looking for confirmation that the policy is assigned and that its parameters are correct. You can also find this information by using the IP Security Policy Man agement snap-in to view the policies for the local machine. Is IKE negotiation succeeding Check the Security Event log. If auditing is not turned on, use the Group Policy Object Editor snap-in to enable auditing. IKE negotiation uses the Logon Events category to report success or failure. If IKE negotiation is not succeeding, check IKE settings. Are authentication, encryption, and key change the same for both computers If IKE is succeeding, is Quick Mode succeeding Check the Security Event log. If Quick Mode is not succeeding, check to see that all Quick Mode encryption, integ rity, key strength, key change, and so on are the same. Do filters make sense For example, if you are entering from and to IP addresses, are they mirrors If you are indicating on one computer from and to ports, is the other a mirror of this Are packets reaching the correct computer You can use Network Monitor to capture IPSec packets. You will not be able to see any encrypted text; however, you will know whether packets are reaching the computer. (You can view the source address.) Also, you will know whether IPSec is being applied. You can also modify your policy to use no encryption and then capture packets to learn more about them. Are packets being dropped There is no IPSec performance counter. Dropped IPSec packets contribute to the Datagrams Received Discarded and Datagrams Outbound Discarded counters in the IPv4 performance object. However, the best way to determine whether packets are being dropped is to use the IP Security Monitor snap-in to see the packets dropped.
Problem 2: Determining Whether Your IPSec Blocking Rules Are Working
You can write blocking rules to prevent inbound and outbound packets. You can restrict packets from or to specific IP addresses or IP address ranges or restrict them by protocol or port. It is easy to test some of these instances: just use another computer and attempt to connect and communicate with the inbound ports or attempt to connect to the computer or use the protocol that is blocked outbound. Other problems are not as easy to isolate; furthermore, you need to ensure that some fluke is not preventing
