Most application passwords are not secure. This
is a tool to open up a password protected QuickBooks file. Word and
Excel passwords are also not very secure. To secure a file, use windows file
encryption. Especially useful for laptops. Be very careful with this, because
you cannot recover the file at all if you forget your password. The encryption
is tied to your user account, and the file will be unrecoverable if that user
account does not exist. Be sure your backup tools support encrypted files.

Windows updates can consume a lot of bandwidth, bringing your internet connection to a crawl. Particularly in larger offices you may want to consider an alternative – WSUS: Windows Software Update Services. This is a program which runs on your server, and downloads the updates once, then updates the workstations from that server rather than from the internet. It also gives the network administrator more control of what gets updated and when. It supports Windows updates, office updates, and some server software updates. A new version is due out by June: http://www.microsoft.com/windowsserversystem/updateservices/evaluation/faqs.mspx

Some of our clients have complained that they are getting emails that look like someone has detected a virus they sent and is reporting it to them, often from an automated antivirus program or firewall. This often occurs because someone with your email address in their contacts list has gotten a virus, and the virus falsely puts your email as the sender (called spoofing). To view the actual source of an email message, you need to view the header details. In outlook, open the message to view it, then click view, options. Copy the section titled message headers to a separate email, and send it to us to look at. For other types of email check here: http://128.175.24.251/headers.htm for how to view the email header. Forwarding the message doesn’t work, because the header will show how the messages was delivered from your server to ours, rather than how the original message arrived.
