I have just set up NOD32 on a 6 user licence. The network consists of 6 WinXP Home machines, only 1 of which (the admin machine) has internet access (via dial-up AOL) Each of the other 5 LAN clients has been setup with the standard NOD32. The internet enabled machine has the admin version on it. I have set up the signature mirror in a folder on the admin machine, the local path being c:\mirror, and have enabled sharing. The admin machine seems to update the mirror folder without issue when updating the signature files off the internet. There are no username or password parameters set in the mirror set up On the client machine, i have added the update server as \\<admin machine name>\mirror\ (i actually used forward slashes, but NOD changes them to backslashes) which i believe to be the correct path to the admin machine across the network (please advise if i have set this incorrectly) When i go to update the client, it always asks me for a username and password, but i don't know which username and password it wants - the licence username and password that ESET provide when you buy the product (and the one the admin machine access the internet update server with) or the username and password used in the mirror set-up, of which none are? I am tearing my hair out here as i believe each machine can see the update mirror, but why each one needs a user and pass to access it i don't know! Or should i have installed the admin version on each machine? (i think not) There are no problems with shares on the machines, and each machine can access shares on the others. Help !!
