AutoRun/AutoPlay is a well known security risk. Pop an infected USB stick into your PC and up pops the autorun/autoplay menu. Viruses can replicate items on that list, so you think you’re just opening it up in Explorer but actually you’re infecting your PC as well.
It makes sense then to disable it. It can be done easily in Group Policy, but if you’re a home user then that won’t be any use to you. Here’s how to do it XP by modifying the registry.
- Start> Run
- Type regedit
- Click OK
- Go to: HKEY_CURRENT_USER\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Policies\ Explorer\ NoDriveTypeAutorun
- Right-click NoDriveTypeAutoRun, and then click Modify.
- In the Value data box, type 0xFF to disable all types of drives.
- Click OK. Exit Registry Editor
- Restart your PC
- Done!
Deleted some accounts or cleared a load of emails from your Exchange server and wondering why the database size hasn’t reduced?
Well, after you’ve deleted Exchange accounts, you need to run the Cleanup Agent for them to actually be removed (and then only after the waiting period, typically 30 days, has passed).
To change the deleted mailboxes waiting period: In Exchange System Manager go to the First Storage Group, right click on your Mailbox Store and click Properties. On the Limits tab, at the bottom, change the number of ‘Keep deleted mailboxes for (days)’.
To run the Cleanup Agent: In Exchange System Manager, go to your Mailbox Store, right click on the Mailboxes folder and click Run Cleanup Agent.
The space you’ve cleared will only be available after the next online defrag has completed (typically overnight). However, the Exchange database files won’t actually be any smaller. Exchange keeps the space in it’s databases ready to use for new emails. You can see how much free space your Exchange server is holding by viewing your Exchange servers Application Event Log (in Event Viewer). Look for the Event ID 1221 that has your Mailbox Store name in it (not the Public Store). The Event description will tell you the megabytes of free space.
To actually make the Exchange database files smaller you need to run an offline defrag. This can only be done during downtime and really isn’t recommened unless you have a lot of free space in your database to release. To run you need to detach your Mailbox Store and run the Eseutil utitlity. More info can be found here.

If you’re running Symantec Antivirus Corporate Edition on your network and you have some 64 bit machines on your network, you may find that the 64 bit machines aren’t updating their virus definitions. This is because the 64 bit machines cannot update from a 32 bit server. The way round this is to set the 64 bit machines to update from the Internet instead of from your server. To do this you need to create a client group with the just the 64 bit machines in, like so:
- Create a client group.
- Drag the 64 bit machines into the new client group.
- Right-click the client group.
- Uncheck Inherit settings from Server Group.
- Right-click the client group, and then select All Tasks > Symantec AntiVirus > Virus Definition Manager.
- In the Virus Definition Manager dialog box, uncheck Update virus definitions from parent server.
- Check Schedule client for automatic updates using LiveUpdate, click Schedule, specify a schedule, and then click OK.
- Click OK.
Done.

Want to know what the difference is between your exchange .edb and .stm files?
.edb: A rich-text database file containing message headers, message text, and standard attachments.
.stm: A streaming internet content file containing audio, video and other media that are formatted as streams of Multipurpose Internet Mail Extensions (MIME) data.
So now you know.
Tried to do Open as web folder in Internet Explorer 8? You’ll have noticed the option isn’t there any more. It’s been removed. Apparently this is because they have done some work to separate Internet Explorer from the Windows Shell.

Then, click ‘Connect to a Web site that you can use to store your documents and Pictures’ at the bottom.
Follow the wizard that pops up and you’re done.
