Consider the following. You have an Exchange 2003 environment. Users are getting the following message from the Exchange PostMaster account on meeting updates or meeting cancelations they sent to recipients outside your exchange organization.


Subject: Delivery Status Notification (Delay)

This is an automatically generated Delivery Status Notification.

 

THIS IS A WARNING MESSAGE ONLY.

 

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

 

Delivery to the following recipients has been delayed.

 

       This e-mail address is being protected from spambots. You need JavaScript enabled to view it

       This e-mail address is being protected from spambots. You need JavaScript enabled to view it


All recipient addresses check good. You check the Outgoing SMTP Queue on the Exchange Server the users mailbox is hosted on and notice the users message is there with a red dot on the envelope icon indicating delivery has thus far failed and a retry is scheduled.

 

Normal messages and initial meeting requests go thru to the same outside recipients with no problem. The same outside recipients can accept the meeting request and the sender recieves the accept message.

 

Then after the meeting update or cancelation sent by the internal user expires in the queue the user will recieve the following NDR message from the system Administrator on the same meeting update or meeting cancelation they sent to recipients outside your exchange organization.

 


Subject: Undeliverable: Delivery Status Notification (Failure)

 

 

Your message did not reach some or all of the intended recipients.

 

      Subject:    [Subject of Message]

The following recipient(s) cannot be reached:

 

      This e-mail address is being protected from spambots. You need JavaScript enabled to view it  on 4/8/2010 8:48 AM

            Could not deliver the message in the time limit specified.  Please retry or contact your administrator.

           

      This e-mail address is being protected from spambots. You need JavaScript enabled to view it  on 4/8/2010 8:48 AM

            Could not deliver the message in the time limit specified.  Please retry or contact your administrator.

           


 

 

Recommendation:

Check if the external recipients messaging system is Exchange 2007 or Exchange 2010. If so refer to this Microsoft Knowledgebase Article.

"A meeting update message or a meeting cancellation message from an Exchange 2003 user is not delivered to an Exchange 2007 user"

 
How To Change The Joomla Icon In The Browser Address bar PDF Print E-mail

This will explain how I changed the Joomla Icon in the browsers address bar and page tab. 1st this works on Joomla 1.5 as it appears most templates use the admin favicon.ico.  

There are 2 websites where you can create an icon on line.

http://tools.dynamicdrive.com/favicon/

http://www.degraeve.com/favicon

After creating your icon, rename the current favicon.ico to faviconico.old in the //administrator/templates/Khepri directory then upload your new favicon.ico in it's place. That worked for me.

Ubuntu Loads GRUB Promt After Update (WUBI) PDF Print E-mail

A copy of this is in my Forums for discussion....

I installed WUBI 9.10 on a Dell Inspiron 5100 32bit. Was running great till I updated it. After updating it booted to a SH:GRUB> prompt. I did some online research and found a series of commands to get booted into Ubuntu 9.10 then from a terminal window run >sudo update-grub2 which fixed the issue. The key for me was figuring out whether I was on sda, sda1 or sda2 and which version I was on. Checkout the below commands

sh:grub> linux /boot/vmlinuz-2.6.31-19-generic root=/dev/sda2 loop=/ubuntu/disks/root.disk ro
sh:grub> initrd /boot/initrd.img-2.6.31-19-generic
sh:grub> boot

After typing "sh:grub> linux /boot/vm" press the TAB key. You get a list of choices. Use the newest vmlinuz-x.xx-xx-generic. Do not use the TAB key for any of the other parts of the command, for example the root=. It will not give you a good list. I've BOLDED the only variables in these commands. The version and the sda?. Also note that in the "initrd" command the version must be the same.

Once you are booted into Ubuntu, open a terminal window and type "sudo update-grub2", press enter, type your root password, press enter again. If you do not see any errors you should be ok. Try to reboot and it should boot ok.

Thats what fixed it for me. Hope this helps for you too.

Here is the forum I found my fix on...

Something To Remember When Taking an Exchange Mailstore Offline With a BES Server PDF Print E-mail

I learned this this last weekend. You have a Blacberry Enterprise Server in your Exchange 2003 environment. You have an Exchange Server with multiple Storage Groups and need to take a few mailstores offline for an extended amount of time. I would make sure the BES-ADMIN mailbox gets moved to a mailstore that is not going offline. If it is on one of the mailstores that is going offline, your BES will will not forward messages as it is unable to access the BES-ADMIN mailbox.  Your Application Event log will begin filling up with 10277 Errors from the Blackberry Messaging Agent saying "Blackberry Messaging Agent (ServerName) Agent 1 failed to start, Error code 5305"

 
Easy way to remember linux file perissions PDF Print E-mail

This isn't exactly how the system stores it, but it's very close and is just an easy way to remember by using binary.

1. Consider each permission for owner, group, other to be three bits each hence

Owner  -  Group  - Other

  000    -    000    -   000

2. Remember this is binary so the value of each place of each of the three bits is  4, 2, and 1 so.

000

Configure Squid as a Reverse Proxy to Serve Multiple Physical Web Servers from one Static IP PDF Print E-mail

I had been looking for a solution to this issue for months. I have one static ip from my ISP. I have an IIS server running DotNetNuke and an Apache2 webserver running JOOMLA (The one serving this content). How could I serve multiple websites running on two or more different servers from one static IP. 
I have a hardware firewall appliance protecting my network.

 

Port 80 was forwarded to my IIS DotNetNuke server. I built a VM Ubuntu 9.04 linux server and installed Squid on it using apt-get. (Had it up and running with squid in less than 30 minutes. Try that with Windows Server 2003 and ISA Server 2004.) I performed the Squid config as outlined below. I have internal DNS running (Windows ActiveDirectory with DNS) so I created DNS zones for each of my web domains with www host records one with the IP of my JOOMLA box the rest to my IIS box. Configured my firewall to send all port 80 traffic to my Squid box.  It worked the 1st time. Cool! Read how I did it by clicking the "Read More..." link below.
