Had some problems during installation some MOSS 2007 servers:
1) MOSS 2007 installation on Windows Server 2008 R2 is only with a slipstream installation possible. How to do this –> http://insomniacgeek.com/blog/how-to-install-moss-on-windows-server-2008-r2/
2) During Upgrading the MOSS 2007 installation with the newest June09 Cumulative Hotfix Package I get some weird error messages. The main problem was this one:
The access control list on 12\template\layouts\web.config could not be modified when installing 941422
Remark: It was not concerning the KB 941422 but the same message in the upgrad logs.
Solution: Copy the web.config from a specific folder on the central admin server to the other server.
