Documenting a SharePoint Farm
Anyone involved with the building / running / supporting of a SharePoint system will know how important documenting the original build configuration is.
If you build farms using the excellent AutoSPIntaller, then most of your work is already done as you have to plan things like your service accounts and database names for the inputs.xml file.
But what if you are called into look at a system that you know nothing about ?. in this case the equally excellent SPSFarmReport will come to your help.
The download zip file has versions for both WSS 3.0 / MOSS (32 & 64 bit) and SharePoint Foundation / SP2010 / Project Server 2010.
Once downloaded onto one of your servers with the binaries installed, simply run the appropriate executable under Farm account credentials, once ran you can delete the executable if needed.
The report output file is a nicely formatted HTML document that covers just about every single aspect of your farm configuration, this can be used to create your documentation guide, and as a timed snapshot of your configuration for future comparison.
