This "scan.dat is locked or missing" has been the bane of my week.

We started seeing this error on Tuesday after agent 3.5.6 came out (we
had left the defaults so it went to everybody without our getting to do
any testing).  Finally traced the error to the new agent version, and
have spent today helping students back out to 3.5.4 (via a batch file
that uninstalls the bad before installing the good, wrapped up in a
self-extracting zip).  

I won't know for sure that this has fixed it until enough people get
downgraded that I feel safe switching the DAT requirement back to
presenting the "update" button - right now it is presenting a link to a
web page, which then links to the McAfee xDAT, which is able to update
the DAT version - though a reboot is required.*

It hasn't been the best week.  The fact that you're seeing errors with
3.5.5 does not make me happy.  Cisco assured us that 3.5.5 did not have
any of these issues, so 3.5.5 is now what you download from our server
if you do a web login - though not too many should be doing that now.

* Actually the xDAT is wrapped up with a batch file now too, because we
had a number of folks somehow end up with correctly updated DATs files
on the hard drive, but the registry a version back, so VirusScan denied
it needed updates while Clean Access insisted it did.  No idea if/how
this is related to the other problems this week.

Subject: CCA 3.5.5 and McAfee DAT 4577

We are running CCA (v3.5.5 across the board) and have suddenly run into
errors with people trying to run McAfee updates -specifically to today's
4577 dat.

# Any AV Definitions Check (Mandatory)
     * Passed Checks:
     * Failed Checks:
       av_def_ANY, Antivirus Check [Any supported AV software up to
date]
     * Not executed Checks:

On the client machine, they get an error that update failed because
"scan.dat is locked or missing." 

This is odd in that McAfee updates have been working without error. I
have machines that updated to dat 4576 yesterday just fine. Today they
are failing with 4577.

Is anyone else seeing this issue? Suggestions?
