Several SEP 12.1 GUPs getting "no connection to SMC service error"
Over the last several weeks I have had an increasing number of site complaining that their endpoints are out of date at their site. We use AD structure to assign policy to all locations. Some 144 GUPs of which 10 confirmed are having the issue, but the SEP Monitor tool says 40 GUPs are out of date.
I have been working with support and the current suggestion of disabling the sysplant driver does not appear to be working as I am still seeing the issue on a few of the GUPs I have been working with directly.
I am currently testing the replacement of the serdef.dat file on one of the servers, but that has only been since last night, but so far it has remained online.
I know in searching the forums assistance has been limited, but the issue does not seem new. I guess what I am not understanding is why do some systems function without issue, but these several keep experiencing the SMC crash. I then begin to wonder if it is only my GUPs or could be more wide spread to normal endpoints. So far I have not been able to easily investigate other systems, so the GUPs remain the obvious because of what happens when they are not running and endpoints go out of date.
Any thoughts or assistance would be greatly appreciated since I have support scratiching their heads. I will continue to work things from that angle as well, but thought it may also help to take the issue to the community for more ideas.
