I used the command line ‘arp -s IP MAC’ command to set a static ARP entry on Windows Server 2003. When I ran ‘arp -a’ it was there as a ‘static’ entry. When I restart, it is gone. Is there some file somewhere like lmhosts where I can make this absolutely permanent? Thanks!

I don’t think there is already support for persistent configuration of ARP entries. However, you should be able to create a boot script that does that every time.
In Group Policy, go to Computer Configuration\Windows Settings\Scripts, add a startup script.
