Symantec Mail Security for Domino offline update virus definition

Dear all,

We plan to upgrade Symantec Mail Security for Domino 8.1.1 and Endpoint protection  12.1 MU2, we need to offline update the virus definition for protect PC

and server, but I try to implement SMSDOM, the SMSDOM virus definition while the server is offline, seems my practice is if symantec endpoint protection

definition is updated, SMSDOM will also update the virus definition after, but I try many times the SMSDOM cant update the virus definition, which problem

occur in my case??

Also I have one question, if I want update virus definition in SMSDOM offiline, which folder should i store it in there????

Thank you so much for attention.
