I've deployed a Cisco NAC solution (utilising CCA 3315) in a OOB Virtual Gateway deployment. So far it's working great on XP clients with single sign-on. However when run on Vista clients a problem occurs when the user idles and the screen locks. When the user logs in again, the NAC agent keeps prompting the user to accept a cert repeatedly. Anyone come acrosss this problem and the workaround/solution?
I searched all opened/closed TAC cases for you to see if this was a common issue. I do not see any cases related to this.
My suggestion would be to open a TAC case and get help right away on this issue.
