Im trying to move the Sharepoint Databases to a different HDD Ive googled
around and found many faqs on how to do it however I am still hitting a brick
wall.

I stopped all the sites and followed this guide :-
http://uksbsguy.com/blogs/ianwatkins/archive/2006/08/12/Moving-CompanyWeb.aspx

which is very similar to the Microsoft ones however I get the error :-

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access
denied.

So again did some research and found that a hotfix may solve the problem yet
again it hasnt the hot fix wont install SQLCritUpdPkg_ENU

I get the error :-

There was an error updating Microsoft SQL Server 2000 or Microsoft SQL
Desktop Engine 2000.

so Im stuck does anyone have any advice as to what I need to do to resolve
this I badly need to move the databases as they stupidly reside on the system
drive which doesnt have sufficent free space to cope with an expanding
sharepoint site.

Regards

Marcus
