Oh joy, just wasted half my life (OK, half a day) trying to install Windows Sharepoint Services 2.0, during which I received the error:
Setup Errors
There are errors in Windows SharePoint Services setup.
Create Config Database : Metadata manifest 'C:\Program
Files\Common Files\Microsoft Shared\Web Server
Extensions\60\bin\sqmcfg.dll' does not exist or has
invalid signature. (Error code: 2779).
Extend Virtual Server : Cannot connect to the
configuration database.
To cut a long story short, it would appear that this error occurs for WSS Setups downloaded before 4 Dec 2004 - now I was installing from a DVD dated July 2004, No: 2426.8. 'Scuse me but I would assume that such a disk would have the latest version but oh no, now I look, the file is dated 23rd November 2003. So now I have to go and download 34MB over my horribly slow link (because I live and work in the middle of what BT considers nowhere). Why do I bother subscribing to MSDN? Come to think of it, I've just had a renewal notice - I don't think I will be bothering.
Well that feels better
