GPO applying logon/logoff script twice - when using loopback policy

i have our main policy set logon/logoff script, assigned of our computers.  have policy (that set use loopback) sets desktop background on of our public computers.

since applied loopback policy public computers i've been noticing script fails on machines.  when in rsop.msc see policy listed twice, both logon , logoff settings:

so on public computers, see:
\\server\logon.vbs     12/8/2010 7:53am   com-user second policy
\\server\logon.vbs     12/8/2010 7:53am   com-user second policy

but on workstation, if run rsop, see:
\\server\logon.vbs     12/8/2010 7:53am   com-user second policy

why loopback setting twice?  how can fix this?

 

 

hi. typically when use merge mode , gpo containing script high in ad structure this:

domain.loc
-gpo containing script
--ou public computer
---gpocontaining loopback merge

cause gpo containing script read twice. try create structure instead or try replace mode:

domain.loc
--ou users
--gpo containing script
--ou public computer
--gpo containing loopback.

have @ better understand loopback:
