I think that I may have to smash my head into a steel door the next time someone tries to argue network performance with me. I have had this conversation WAY too often for 15 years and can’t take it anymore. I have to blog about it in the hopes of performing some enlightenment. There are way too many people that try arguing that their ping latency is next to nothing, and they usually debate that their WAN is perfectly stable. Trust me, you’re wrong, wrong, wrong. Please allow me to explain why.

PING MEANS CONNECTIVITY – I am SO tired of people telling that they have great WAN connectivity between their sites with excellent ping times. Ping s a very poor indicator of data transfer latency because it runs as an ICMP protocol on IP, and has high priority. Getting a ping response from another machine means that it’s on the network, nothing more can be reliably discerned. One of these days I’ll write a little utility that uses TCP and UDP to send user definable data payloads to another machine and measure that...

System migration is a difficult and time consuming process, only your boss’s boss thinks otherwise. They never spent all those weekends freezing in the data center wasting countless hours doing migrations, waiting for backups and restores to complete, reconfiguring system settings, testing, tweaking, promising the family that you’ll be home soon. This is migration and anyone that says otherwise, hasn’t really worked in IT. In-fact, that should be my next litmus test for an interviewee. “So, how long did your last migration take?” An immediate shrug and drooping of eyes will indicate an affirmative of real world experience and not another paper certified semi-professional. If the candidate immediately throws their coffee into the wall, then they’ll get an offer immediately. Do not pass Go; please go directly to HR and begin doing your new hire paper work.

I guess that it’s hard for most non-IT people to understand the pain and suffering that comes with migrations because they probably have misconceptions...

I ran into this issue today when finally rebuilding my lab DC01.Contoso.com and using DCPromo. This warning pops up and since I had crippling DNS issues in the past (Thanks again Mike D!), I got really nervous.

 



 

Solution: It seems that this message can be safely ignored in my case because according to the article that I finally dug up (http://social.technet.microsoft.com/Forums/en/winserverDS/thread/38ccac86-375c-4402-9bfc-660ce5c0a606),...

Picked up the new Droid phone this weekend on Pete D's advice. We have the same picky taste in phones. I.e. iPhone was a cool idea, but no physical keyboard sucks (I touch type... and write a LOT of long emails), AT&T sucks (Duh, bad), Apple sucks (yes, I'm still pissed about the screwing they gave us on the Apple IIGS and shall remain so forever), no tethering sucks (I do this a lot too when on the road, some emails/docs just can't be typed on a phone), no I don't want jail break crap. Battery always worries me, because I use my phone a LOT for business and personal, so I'm always cranking away when I'm out of the house, but I figured I'd give it a shot because my Moto Q has reached the end of its' useful life for me. The Droid solved all but the tethering problem on day one and that's coming in January, so I can live until then.

One of my big dilemas, albeit not nearly big enough to stop me from buying it, was accessing my hosted email accounts (here and others). I host them on Live Mail, which is totally...
