From Why can't I ping my freshly set up amazon web service EC2 instance? it seems that the architects from Amazon's AWS have chosen to block ICMP by default.
Is there some official source stating their reasoning for that? I assume it is because of security but I'd like to be able to read their official stance on it, if possible.
Is there a way to manually trigger a Root Certificate Update?
I'm troubleshooting a problem with a certificate that keeps disappearing from the Certificate Store. I think this is related to Trusted root certificate being automatically removed from store. But I want to be sure, so I need to be able to trigger the Root Certificate Update - otherwise I have to keep waiting for it to happen at some random time.
Sorry for the dumb question, but I have a Windows XP box we use for a 'server' in the LAN network to store various important files. We have 2 hard drives (1 TB each) and want to use the second one for a daily backup, just in case the first one fails. I'm thinking of running a scheduled batch file, something like this:
for /f "tokens=1-5 delims=/ " %%d in ("%date%") do set BackupDir=e:\%%e-%%f-%%g\
mkdir %BackupDir%
xcopy /s /-y C:\SourceSafe %BackupDir%
The files are 4 GB in total so it'll take more than half a year before the hard disk runs out of space.
I am wondering if there are potential problems with this way. Thank you.
