I have a HP LC2000 U3 server, 512MB RAM, Hardware RAID5 and running Win2k Server, Exchange Server, McAfee TVD Ver 4.5, Groupshield for Exch 2000 and Arcserve 2000 SP3. My problem is that occasionally the boot.ini just disappears. I ahve created a diak with the original boot.ini, ntldr and ntdetect that will allow me to boot the server if these files are missing but I still cannot get to the bottom of why it is being deleted. I have run a full virus scan on several occasions and nothing found. No-one else has access to the server and I keep the administrator password very secret. Has anyone else experienced this or is this a known issue with some of the installed software that I am unaware of?
