File permission errors

[zebrafilm]

Running WSRV2008 R2 web X64

after I migrated from an X86 server to this X64 server I have constant trouble with file and directory settings/permissions.

I have run the reconfigurator many times, did all checks but it doesn't get better.
Running the checks gives me even more trouble with programs like SmarterStats /mail.
temp and app_data dirs get the wrong permissions and programs cannot write there any more.
I also had a site that suddenly could not access it's own webconfig.file...

Any clues where to look?
