Overheat may also cause the problem. I experienced this kind of problem too. Then I placed the server to another place and it is OK already. rizwan@xxxxxxxxxxx on 12/02/2002 12:03:11 PM Please respond to "[ISAserver.org Discussion List]" <isalist@xxxxxxxxxxxxx> To: "[ISAserver.org Discussion List]" <isalist@xxxxxxxxxxxxx> cc: (bcc: Long Choo Chong/AMA/ACI) Subject: [isalist] Re: After installing ISA server reboots twice a day http://www.ISAserver.org I think that you should get your RAMs checked, because i have faced the same problem with my Domino mailserver and problem solved by changing RAMs. I think you should give it a try.

I have just installed ISA server with isa sp1 on a win2k web server of ours. Since then this machine reboots itself at least twice a day. It has been happening outside office hours so I am not able to see what the blue screen says. There is nothing in the event logs when this happens except for the messages when it restarts. We have IIS running on this machine also with a number of websites published using IP Packet Filters. Has anyone had this type of problem before ? Where do I start to narrow down the problem ? Reinstalling this machine is the last resort, I will only do this if I cannot find any other way. Patrick
