Windows Hosts - ssl handshake event log errors

We are running nagios and have nrpe installed with ssl. All of the checks work properly. Nagios does not display any error messages. However, windows host ALL contain NRPE_NT: Error: Could not complete SSL handshake. 1:5:0. If I disable SSL on the windows client (nrpe_nt -i -n) then we see the SSL handhsake error in nagios as the handshake is actually failing and so all checks fail.

Error occurs on Windows 2003 and 2008 servers.

These errors are filling the event logs. Any idea how we may eliminate these.
