Kepner-Tregoe: Houston, we have a problem!

The Apollo 13 team is famous for bringing back the astronauts stranded in space by solving difficult and complex problems. The teams solving the problems using the Kepner-Tregoe (KT) methodology and some pointers and resources are displayed on this blog. KT is one of the recommended ITSM/ITIL problem solving techniques. Here is a presentation about problem solving in IT which includes Kepner-Tregoe and here is a presentation to the ITSMF. Sun Global Resolution Troubleshooting (SGRT) blog is here and uses a modified Kepner-Tregoe.
The Fallacy of People Problems, and How to Solve Them is an article which points out that there are a number of causes to be investigated, usually human related.
The KT template is available here.

Guerrilla capacity management

Crucial to the Guerrilla methodology is to create a rudimental service catalogoe and have a skeleton CMDB. The template for Guerrilla Capacity Management is available here.

Another one for the Doep

Doep is the only one who reads my stuff about network best practices. Thus, here is another best practices configuration for my old mate, Doep. (Payment in Guinness!) This configuration above is to setup Outlook Web Access for Exchange to external users from the Internet. It entails using a Checkpoint Charlie configuration. A Checkpoint Charlie configuration is the use of reverse proxies in a DMZ that is accessed externally from the Internet. The external incoming connections are terminated on the reverse proxy, which then presents the web pages which have been backhauled internally from the server farm. In this case, the reverse proxy is Microsoft's ISA server 2006. You can also read more about ISA, here.
A Checkpoint Charlie configuration can be used for any type of Intranet application that is hosted on a server farm and needs to be presented to external users.

Exchange Checklist

Exchange is Microsoft's messaging platform. The latest version is Exchange 2007. This follows on from the previous checklists that was more around network troubleshooting. This is a checklist for Exchange. Jetstress testing should be performed before you install Exchange on the server. Download it here. There are some well-known risks associated with running Jetstress on a machine with Exchange installed. The first is that Jetstress could potentially delete some existing logfiles if it's configured to use the same log drives that Exchange is using. The second is that if you use a version of Jet (ESE.DLL and ESEPERF.*) different than the version installed with Exchange, the registration of the Jet database counters in the Jetstress install directory will break the database counters for Exchange after Jetstress is removed.
