Have you ever wanted to see a list of all messages in a folder that are either unread or flagged for follow up?  Well… If you’re like me then you probably receive 100 + e-mails a day and just can’t read them all at once.

Here is a nifty filter that you can create in Outlook to accomplish this:

  • Make sure that you are in a mail folder (such as Inbox)
  • Go to view menu -> current view -> define views
  • Select “Unread messages in the folder”Click Copy, Enter an appropriate name such as “Unread and/or flagged messages” and leave other settings as is
  • Now select the newly created viewClick modify, then Filter
  • Go to SQL tab, check the tick box “Edit these criteria directly. All other tabs will be unavailable”
  • Paste the following into the text box:
  •  ("urn:schemas:httpmail:read" = 0) OR ("http://schemas.microsoft.com/mapi/proptag/0x10900003" > 1)
  • Click OK, OK and Close

You can now select this view in any folder you please.

This filter should show all unread messages and any message flagged for follow up that has not been completed yet.

I have not tested this extensively but have been using it for a while now and all seems to be in order with the filter.


Spyware vs Virii

posted by Sam Ravenscroft
Sep 4

Spyware and viruses are both forms of unwanted or malicious software, sometimes called “malware.” You need to protect yourself from both.

What’s the difference?

Spyware (sometimes called adware) collects information about you without appropriate notice and consent.
A computer virus spreads software, usually malicious in nature, from computer to computer.

Spyware can get installed on your computer in a number of ways. One way is through a virus. Another way is for it to be secretly downloaded and installed with other software you’ve chosen to install.

In short, spyware is a specific type of unwanted software that secretly collects your information.

A virus is a specific way software can be secretly distributed, often by e-mail or instant messaging.

Both spyware and viruses can cause damage to your computer or cause you to lose important data.

To help protect against spyware, try Super Anti-Spyware.

To help protect against viruses, try Avast (a good free-for-personal-use anti-virus) or software from another antivirus provider.


HOW TO: Debug Memory Dumps

posted by Sam Ravenscroft
Sep 4

When you get a stop error (Blue Screen of Death or BSOD), your computer generates a small file or memory dump usually referred to as a minidump. This BLOG post will explain to you how to analyse these minidump files. This may shed some light on the problem in terms of what caused a particular stop error. It may also give you the driver file name if the stop error was caused by a faulty or incorrectly installed driver.

Your first step is to download and install the Microsoft Debugging Tools found here: http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx

Once you have downloaded and installed these tools, go to start, all programs, Debugging Tools For Windows, Windbg. Once you open Windbg, you will presented with a blank screen. Click on File, Symbol File Path. Here you will enter the symbols path. Symbols are needed to effectively debug.

The path will be:

SRV*c:\symbols*http://msdl.microsoft.com/download/symbols

Enter in this path and click OK. Now, go to File, Save Workspace so that your symbols path is saved for future use. Now what you want to do is locate your memory dumps. They are usually located in %systemroot%/minidump (in general C:/windows/minidump).

If you notice, they are usually named the date, and then a -*number* to indicate the order of minidumps that day. My example is called Mini061904-01.dmp .

Inside of Windbg, go to File, Open Crash Dump and load the file. You will get a message to save base workspace information. Choose no.

Now you will get a debugging screen. Now it takes a little bit to run it, as the symbols have to be downloaded as they are needed. Then you will see information such as:

Symbol search path is: SRV*c:\symbols*http://msdl.microsoft.com/download/symbols

Update: After the intial run of the debug process, you can use the command !analyze -v to gather more information.

Now that may be more infor than you need. This tutorial only covers minidumps, however, if needed, you could change your memory dump options to do a complete dump. This is useful, however, very cumbersome, as the file generated will be the same size as your amount of ram.

Note: Make absolutely sure that your symbol path is correct. If it isn’t, then you will get symbol errors and not likely be able to debug the dump to get the info you desire.

Author note: This article source is from a posting found on Majorgeeks.com’s forums.



I have been receiving this error on my SBS 2003 R2 server (with SP1):

Error category : Resource Errors
Error : e000fedf - A failure occurred reading an object.
For additional information regarding this error refer to link V-79-57344-65247

If you follow the link it will redirect you to Symantec’s site. Instructions found there will direct you to enable debug logging on some of the services.

The information found there will give you an example, showing the the file sfcfiles.dll as being corrupt. I followed the instructions and coincidentally found the exact same file to be corrupt on my server as per the log files generated during a backup of the system state.

I compared the version of the file on my server with another healthy server and found that the MD5 hash of the two files differed. I copied the healthy file onto my server and ran another backup of the system state, but the problem persisted.

Symantec forums directed me to re-install Windows Server – SP1 which solved the problem.



So you’re all excited… you just installed Outlook 2007 and you think it’s great… until your friends start forwarding you all those funny e-mails we all love to receive, but you can’t see the animation in animated GIF images.

This is not a bug in Outlook 2007, but rather a feature (that I am sure most will find rather frustrating).

As per Microsoft:

Other Unsupported Web-Related Features
The following is a list of all other Web-related features that Word 2007 does not support:

  • Animated GIF images. Only a static representation of the GIF image shows.
  • Flash. Only a red “X” shows in the area where the flash would display.

For full details please see:
http://msdn2.microsoft.com/en-us/library/aa338201.aspx

Currently there is no known quick solution for this, but one workaround is to save the e-mail message somewhere on your hard drive and then open it using your favourite browser.

Here’s how you do it:

  • Select the message, don’t open it
  • Click file, save
  • It should be in htm / html format by default
  • Browse to a folder where you can open the mail from (I always use my desktop)
  • Double click the file on the desktop and voila your message displays in your default browser (typically Internet Explorer) and you can see all the animations.
  • Once your done reading (and hopefully laughing), close Internet Explorer
  • Rember to delete the file and folder created by saving the message – you don’t want to waste disc space or clutter your desktop

SMTP Problem solving

posted by Sam Ravenscroft
Jun 2

About 2 weeks ago I was assisting a friend of mine to upgrade her server hardware. They had also moved to a new ISP for hosting et al.

We had some problems with the outgoing mail queues in Exchange 2003. Exchange was setup to deliver mail directly (via DNS). Not all of the mail could be delivered.

The tools used to debug these kind of problems are nslookup and telnet. (There are many other tools available, but these 2 tools can be used on any out-of-the-box Windows / Server installation.)

Let’s say for example that you cannot send mail to [email protected]

Open up a command prompt (start, run, cmd)

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\>nslookup
Default Server: UnKnown
Address: 192.*.*.*

> set type=mx
> microsoft.com
Server: UnKnown
Address: 192.*.*.*

Non-authoritative answer:
microsoft.com MX preference = 10, mail exchanger = maila.microsoft.com
microsoft.com MX preference = 10, mail exchanger = mailb.microsoft.com
microsoft.com MX preference = 10, mail exchanger = mailc.microsoft.com

microsoft.com nameserver = ns5.msft.net
microsoft.com nameserver = ns1.msft.net
microsoft.com nameserver = ns2.msft.net
microsoft.com nameserver = ns3.msft.net
microsoft.com nameserver = ns4.msft.net
maila.microsoft.com internet address = 205.248.106.64
maila.microsoft.com internet address = 131.107.115.212
mailb.microsoft.com internet address = 131.107.115.215
mailb.microsoft.com internet address = 205.248.106.30
mailc.microsoft.com internet address = 131.107.115.214
mailc.microsoft.com internet address = 205.248.106.32
ns1.msft.net internet address = 207.68.160.190
ns2.msft.net internet address = 65.54.240.126
ns3.msft.net internet address = 213.199.161.77
ns4.msft.net internet address = 207.46.66.126
ns5.msft.net internet address = 65.55.238.126
> exit

C:\>

Here’s the breakdown:

nslookup // this is a command line tool to perform DNS lookups
set type = mx // this tells nslookup that we are interested in MX record (Mail eXchanger)
microsoft.com // this is the domain for which we want to do the lookup
exit // self explanatory

The results we are interested in are:

Non-authoritative answer:
microsoft.com MX preference = 10, mail exchanger = maila.microsoft.com
microsoft.com MX preference = 10, mail exchanger = mailb.microsoft.com
microsoft.com MX preference = 10, mail exchanger = mailc.microsoft.com

Basically this means that the domain Microsoft.com has 3 mail servers (or mail exchangers) and that each server has a preference of 10 (lower preference means more preferred, i.e. your backup MX server should have a higher preference that your primary MX server). When the MX records for a domain have the same preference it is used for load balancing as neither is more preferred than the other.

Ok, let’s proceed to telnet. From the list above we will use maila.microsoft.com as it is the first in the list (in a different scenario you would choose the primary MX server, i.e. the one of the lowest preference).

(once again from a command prompt)

C:\>telnet maila.microsoft.com 25

ehlo localhost.localdomain // ehlo command

quit // close the connection

The response:

550 5.7.1 Email rejected because 41.*.*.* is listed by zen.spamhaus.org. Please see http://www.spamhaus.org/query/bl?ip=41.*.*.* for more information

And that is how it’s done. Obviously the response code will differ according to what the problem is.

Under normal circumstances one would simply use nslookup and telnet to debug the problem, but I found this great tool called bmail from Beyond Logic it can be downloaded from http://www.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm

Bmail is a command line mailer, you will still need to obtain the MX record using nslookup, but thereafter it is much easier to use bmail.

Example:

(from the command line)

C:\>bmail

Scheduled Disk Defrag

Credit goes out to Doug Knox for this one.

Microsoft Windows offers a built in tool for defragmenting your hard drives. Sometimes it can be hard to defragment many hard drives on remote machines regularly without the help of 3rd party tools. The following is a visual basic script which will allow for this.

Copy and paste the following text into notepad and save it as a .vbs file.

Problem with Add Remove Programs

May 20

Whilst working on a new site this weekend I almost lost it:

Trying to open Add Remove Program (or run appwiz.cpl) results in:

—————————
Parser Message
—————————
Value creation failed ” at line 451
—————————
OK
—————————

So after many hours of Googling, here’s the fix:

SOLUTION:
copy shellstyle.dll to system32

I located the file shellstyle.dll on a known working system.

The error was experience on an SBS 2003 R2 (Premium edition) server.

Problem could be related to custom OS installation disc created by NLite – but more on that later.


Holiday sweet holiday

Hmm, so I never did post that update.

Sorry about that, but I have been extremely busy and am currently on holiday in the beautiful Isle of Man (02/03 till 04/04).

It is such a pleasure to be in a country where the internet just always works and where there are no “planned power outages”.

I’m currently working on some new ideas (restructure my schedule etc.) and will hopefully be able to allocate a daily (or at least) weekly timeslot to update my blog.

Until then, cheers!
