There are no logon servers available to service the logon request


I have a odd issue.  I have a new client and there is a user on the domain that when she logs off if she loses network connectivity her Windows 7 Pro PC constantly says "There are no logon servers available to service the logon request"".  Windows 7 on a domain typically caches credentials, or at least i thought it did with my experience.  We have joined and rejoined the PC about 10 times and still have the time error.  We are at a loss.  This is a SBS Server 2011 and we are wondering what is making the computer not cache her credentials.  Other users in the office don't seem to have this issue, just one user, who happens to be the CEO (go figure right).

Any ideas on what to try?

Search the registry on the machine for CachedLogonsCount, and see what it's set to.  If it is set low, try increasing the value.

If the time on the machine is different than that of the domain, authentication will fail.  Make sure they are within 5 minutes of each other.
