Environment: Windows 7 SP1 Professional 64-bit
SEP 12.1.4 - UNmanaged clients
We are looking for a solution, please do not tell us to run SymDiag, or reinstall/update to the latest unless you absolutely know it will fix the problem.
Beginning Friday, September 22, 2017, we started getting an error on ALL clients when downloading the 170922012 IPS def update. The error is "An update for Intrusion Prevention Signatures from LiveUpdate failed to install. Error: Postsession callback failed (208)." We are downloading directly from the Symantec LiveUpdate server at liveupdate.symantecliveupdate.com. Nothing has changed in our environment
We can manually run LiveUpdate from the client UI a second time and the IPS update is successful.
What exactly is a "Postsession callback failed (208)" error? Has anyone else experienced this problem with the 09/22/17 r12 IPS defs?
We're assuming that there is a Symantec issue with the 09/22/17 r12 IPS defs since it's happening on all machines.
Absolutely nothing has changed in our environment.
Hopefully someone from Symantec will see this and investigate.
