A delay occurs during IPsec renegotiation on a computer that is running Windows Vista or Windows Server 2008

Symptoms

Assume that you have a Windows Vista-based or Windows Server 2008-based computer that is running in a Windows Server 2008-based domain environment. On this computer, a Group Policy setting that triggers Internet Protocol security (IPsec) policy change and renegotiation is updated. In this situation, a delay occurs during the IPsec renegotiation process. Additionally, the applications that rely on the new security association (SA) are disconnected.

Cause

This issue is caused by a race condition that occurs when IPsec policy negotiation is triggered. Because of this delay, the new SA is disconnected.

Resolution
