Remotely Deploy Software: “Was that where we was supposed to went?”

This is a phrase that you never want to hear when discussing a completed remote software deployment project.

Actually, due to its horrific grammar, this is a phrase that you never want to hear under ANY circumstance. Oh, and Yes, this is an actual quote. Not third person. Not from a friend of a friend. I was there. I heard it. My ears will never recover.

No, the quote isn’t from Deadwood or any other show which depicts uneducated ignoramuses getting by in a cruel world.

Yes, that quote was spoken by a man in his mid thirties who happened to be two months away from getting his grubby hands on his Master’s Degree (from a reputable university, no less).

It was only after missing a freeway exit outside of King Of Prussia, Pennsylvania that prompted my, then, co-worker to utter the words “Was that where we was supposed to went?”

About 18 months ago I wrote about how happy I was with Dameware Mini Remote Control. While I am still very happy with the product I did break a deployment rule that I know well. Basically I screwed up.

What did I screw up? I will sum it up with another quote (this one is actually famous): “Plan your dive and dive your plan.” I learned this when I was getting certified for SCUBA. It basically means that we need to plan what we intend to do and then do what we actually planned.

I didn’t actually do the due diligence that I should have when helping a customer with rolling out DameWare and as a result I made the management of the application a little more labor intensive. You see, in DameWare Mini Remote Control there are two methods for storing Remote Control configurations on target systems. The default and, apparently, most common method is via the file DWRCS.INI located in the %WINDIR%\System32 directory. The other method which I should have pursued is to store all the configuration data in the Windows registry.

This decision was especially bad because I already have a method for collecting the values of certain registry keys from target systems and storing the data in an Inventory database. I could have, with a simple SQL query, been able to view ALL the DameWare remote control configurations for ALL of the customer’s computers. 

The fix is not as bad as you may think, but it does require that I rebuild the DameWare Mini Remote Control agent (for future deployments) and make file modifications to all of the computers that currently have the previously deployed agent.

I can do this quietly so as to not disturb the end users but I despise doing anything to production computers that isn’t necessary. Deploying the agent with the correct* configuration in the first place would have been, ahem, much better. Needless to say, I am ready for the Windows Admin Drinking Game.

OK, so I did “dive my plan”, but diving a crappy plan still sucks. I should have taken more time with my decision. I should have anticipated that modifications to the configuration were inevitable. While we can’t necessarily anticipate WHICH configurations will be changed in any project we should know that SOME configurations will most assuredly be modified. Planning an efficient modification process is integral to any successful deployment.

So, when I fully realized my error I found myself muttering “Was that where we was supposed to went?”
