I have a sonicwall TZ300, that seems to be causing our AD server to peak above 90% when someone log's in on the SSL single sign on VPN.
The reason we believe it's the VPN SSO, is that the we can see on the server, CIAservice.exe hit 49% cpu usage. This service is the SSO agent that links to our AD.
Any idea how we can stop this from peaking so much ?
