I've written a book with Don Jones on advanced VBScript topics. The book starts with a crash course on Windows scripting so even if you've only had a little exposure to VBScript, WMI, or ADSI you can get up to speed quickly. In the book we cover some advanced WMI scripting techniques, getting the most out of ADSI and LDAP queries, working with HTAs and how to leverage scripting with Microsoft Exchange 2003, Microsoft Operations Manager, Virtual Server 2005 and Group Policy.
The book should be available by the end of January 2006.
