Not sure why, but for some reason my smart host in Exchange 2007 can’t resolve DNS names. If I drop to the command prompt, I can resolve and ping fine, but if I use the FQDN in the smart host setup, I get 451 errors.

Smart Host Setup
So, the solution is to just use the IP address that the record resolves to. Put that in the IP address box of the smart host setup screen. That should do the trick!
I believe this has something to do with IPv6, but I didn’t have time to look into it very in-depth…

Let it be known that BES or BPS version 4.1 REQUIRES a certain version of Java. That version is: Java 2, SE v1.5.0_11. You can download it here.
Without this version of Java, you will have many different problems. The problem I was having was with the Blackberry MDS Connection Service not starting. I got the following error: The BlackBerry MDS Connection Service service terminated with the following error:
The system could not find the environment option that was entered.
Today i had an issue where a workstation running XP Home edition would BSOD when you logged in. The BSOD occured sometime while loading the tray icons - normally. After a lot of troubleshooting (which basically just involved disabling services via msconfig until the problem went away) I figured out that the Plug and Play service was the culprit.
I checked the dependencies tab on the services properties to see what services depended on the Plug and Play service to start. I then disabled all the services that were dependant upon the Plug and Play service and I enabled the Plug and Play service. After a reboot, everything seemed to work fine.
I then started enabling the services which were dependant upon the Plug and Play service. It turns out the Windows Audio service was the culprit. I’m guessing that either a sfc /scannow or a remove and reinstall of the sound card drivers would have resolved the problem, but I didn’t get a chance to try because the client said, “Oh well, we don’t want sound on that computer anyway.” He asked me to leave it as is, so that was that.
Hope this saves someone else some time!

This problem has several symptoms but basically what is happening is that when a user logs in, they get no desktop icons, no start menu, and no task bar. If you do a CTRL+ALT+DEL, you will see that explorer.exe is not running, but you can do a File->New Task and start it. Once started, everything is normal.
You may login and the computer just logs you out immediately without a chance to do the CTRL+ALT+DEL and task manager thing.
In either case, the solution is the same. The problem is due to a missing userinit.exe file. This file should be located in C:\Windows\System32 (if you are in XP). You can restore it from your operating system CD by either starting explorer and browsing your i386 folder on the disk or, if your computer is logging you out before you can do that, you will have to boot from the CD and use the recovery console.
All the best!

Well, while trying to start an IPSec service today, I got this error:

IPSec Error
Error 10107: A system call that should never fail has failed.
Almost made me laugh… anyway, I definitely agree about the “should never fail” part. Most of my time I spend fixing or troubleshooting things that “shouldn’t have broken!”
Ok, the problem and the fix?
The problem is corrupted Winsock. The fix is here: http://support.microsoft.com/kb/811259 or you can use this little tool to do it for you: http://www.snapfiles.com/get/winsockxpfix.html (which is what I did)
Anyway, let’s go see what else shouldn’t be doing what it is doing.
After a virus removal today, I started getting the above error message. The fix is to click start, run and run the following command:
regsvr32 C:\Windows\system32\msxml3.dll
To save someone else the trouble, if you need the above driver…. Try here: http://downloadmirror.intel.com/16023/a08/infinst_autol.exe

…Or not so happy.
After spending WAY too long trying to get my sip phones to register on a remote Trixbox, I figured out that the problem was due to my local Netopia router/modem from ATT messing with my SIP traffic. Here is the solution:
Telnet to your Netopia and:
The setting is not in the web gui. You have to telnet into the
router, then type. Each line is a new command.
configure
set ip sip-passthrough off
save
exit
Restart
On the Netopia 4622xlt
Telnet into the device
Use the arrow keys to highlight ‘quick menu’ and press “ctrl-n”
That brings you to the console.
type:
ip nat alg sip enable no
save
exit
restart
That info came courtesy of the following website: http://www.junctionnetworks.com/knowledgebase/onsip/devices/router-configuration/netopia
Well my Blackberry, which I love, just quit cold. Everything was working flawlessly, then one evening at 6:15 PM, it stopped. No telltale errors in the event log would explain it.
I happen to have a good friend and client who had just been through the same problem a couple days ago. I called him and he said to go to Options->Advanced Options->Service Book (0n the phone) and delete every service book that started with “Desktop”.
After you do that, then you go to the BES, and resend the service books for that user. That fixed my problem.
Interesting that we both had the same problem within a couple days.
Ok, I’m happy now - back to Christmas celebration.
