SYMPTOMS
When you establish a connection between a computer that is Internet Protocol security (IPSec) aware and a computer that is not IPSec aware, you cannot make another connection between the computers for 60 seconds. For example, you cannot make a connection using FTP. After 60 seconds, you can make another connection successfully.

Note IPSec-aware computers include computers that are running Microsoft Windows Server 2003. Computers that are not IPSec-aware include computers that are running Microsoft Windows NT or UNIX.



CAUSE
This problem occurs because Windows does not successfully account for the initial connection when it accounts for pending connections on a security association.
