Re: 2003 server built in dos prevention??

Offhand I don't know what is happening and you may also want to post in the
server.networking newsgroup but I did find the link below which may be of
help including registry entries that you can modify to change settings. Also
always look in the application/system logs after a problem occurs for any
hints and enable auditing of system events in Local Security Policy
[secpol.msc] that may then enable more system type events to be
corded. --- Steve
