It should not matter with the OS. What I did was take a PC running NT workstation 4.0, and install the NAVCE Server software (Not Client) onto the PC. Then in the SSC set this PC/Sever as the primary server. Then set your other severs up to download updates from the Primary Server. You can do this in the SSC. Right click on the server(s), select "All Task", "Norton AntiVirus", "Virus Definition Manager". Make sure that the "Update the primary server of this group only" is checked and "Update virus definitions from parent server" is checked. I also have "Do not allow Client to manually launch live update" for the simple fact that people get happy fingers!
Then, on to the clients. Select the client(s). Right click, select "All Tasks", "Norton AntiVirus", "Virus Definition Manager". On this I have checked, "Update Virus definitions from parent server", and "Do not allow clients to manually launch Liveupdate" checked.
Once this is set up all the servers will get there defs from the server/pc and from there the clients will receive theirs from the parent PC. NAVCE defaults to check for updates every 60 mins. I changed mine to update every min, just so I could get them updated. I then changed it back. I have since found an easier whay to do this. Select your server(s), real and the server/pc, right click, select "All Tasks", "Norton AntiVirus", "Virus Definition Manager". On the bottom half of this window, were is says "Update Virus Definitions from parent server, click the setting button and run this down to a min. But remember to change it back to 60 min or what every you want.
Once you have all of this, goto
ftp://ftp.symantec.com/public/english_us_canada/antivirus_definitions/norton_antivirus_corp/static/sarcx86.exe
This will start the download for the updates. You can download it to the server/pc or on your net. I put mine in the nav folder on the main server (the real file server, not the NAVCE server). Run this on the server/pc. This will update your defs on that server/pc, and from there it trickles down to all the other ones. You will see in the SSC the defs updating for all the clients. The current one that I have is "31219h" It is the newest update for the christmas.exe virus. With this, you only have to update the spare PC, and it will update every thing for you.
I do not have any code as of yet, but I am hard at work to automate this. The setup that came with NAVCE does not work, so I am going to make my own. I will share when It is compleated.
Email me at lkress@etigeo.com and I will help to get everything updating if I can.
