Hello Duggy,

it is enough to set update for only one symantec product on one machine
(they will share it). I would recomend you to do it for nav and to use
scripts to automate inteligent updater downloads on daily basis, as live
update is available only every wednesday. Do not forget to exclude AV TEMP
folders, M drive, inetsrv from scanning.In case you have problems with
memory allocation on advanced server you shoud see a message in app log
saying something like: "your working memory is fragmented and you need to
restart your server". Depending on the number of users, you should decide
do you need additional memory (I have 4GB on exchange). If you have
'space' do not host DC and exchange on the same machine. If you do not
have enough servers (machines) you may try to host the DC replica on a
desktop (for backup purpose). What version of SAVFMSE you use?
