How do you force a web browser to fully reload a web page?

When a web browser is instructed to load a web page, it compares the existing web page with the cached web page.  If changes have been made to the existing web page that are not present in the cached web page then it loads the existing web page.  However if an Adobe Flash file or a picture on the existing web page have the same name as the cached web page then this information will often be loaded from the cache.  This can be an especially frustrating experience.  Some recommend the use of META tags which by themselves have distinct limitations that do not address the issue described.  Some recommend changing the filenames on a dynamic or continuous basis.  This solution works but could be quite elaborate.  I believe the following solution is simple and the most comprehensive.  The following javascript fully reloads the web page once on load: Javascript (reload.js): function reload() { if (self.name != '_refreshed_') {     self.name...

How do you block spam using Microsoft Exchange Server 2003?

Please Note: The following instructions involve Sender Filter.  Sender Filter like all Microsoft Exchange Filters will only work if your Server is configured to use the SMTP Virtual Server.  If you are using the SMTP Connector, Exchange Filters are not applied to incoming email.  The only way of blocking email received by a Microsoft Exchange Server using the SMTP Connector is to address the problem using your Email Provider's webmail application.  For example if your incoming email is hosted by Yahoo, you would login to each individual webmail account and block the spam by domain or individual email address.  Please be aware that a small number of Email Providers do not use a Real Time Block list (RBL) nor do they provide their customers with webmail which allows them to block spam by domain or individual email address.  In those instances, you may want to switch to a professional Email Provider such as Yahoo Mail or Google Gmail.  You would then use ...

How do you login as Administrator when Administrator is not displayed on the Welcome Screen?

There are two methods of logging into Windows XP - using the Welcome Screen or using the Username/Password dialog box.  The Welcome Screen is a graphical method of logging into Windows with an icon next to each Username.   The Administrator Account is a Built-In Account which cannot be removed.  Sometimes however, it is not displayed on the Windows XP Welcome Screen.  To login using the Username/Password dialog box rather than the Welcome Screen, please do the following: At the Welcome Screen, hit CTRL-ALT-DEL. The Welcome Screen will disappear and you will then see the normal Username/Password dialog box. In the Username field, type: administrator.

Some errors occurred while processing the requested task.

If you begin to encounter the error message "Some errors occurred while processing the requested task." in Microsoft Outlook Express, it may indicate that your Outlook Express DBX files have become corrupt.  Corruption can occur due to fragmentation on your hard drive, a virus infection, the amount of mail stored within Outlook Express, etc., etc.  Unlike Microsoft Outlook PST files that can be repaired using the Microsoft Outlook Inbox Repair Tool , Outlook Express does not include a free repair tool.

What is the fastest method to copy files?

Through trial and error, I have found that FastCopy is in fact the fastest method of copy.  This copy utility copies files using a large cache that is much faster than the standard copy/paste.  The best part is that if a file cannot be copied - rather than stopping the copy process and awaiting user input, the file is denoted on the screen as being skipped and the copy process moves on to the next file.  When the copy process completes, you can then investigate the reason for the skipped file.  The installation file is available from Cnet Download above. http://www.smartnetadmin.com
