The local harddrive of a client can be changed in a citrix invioment.
Create this on the server if you want it to be x:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix]
“InitialClientDrive”=”x:”
Type REG_SZ

On a terminal server all users are requested to enable or disable the protected mode in the new Adobe Reader X. On some systems enabling does not work.
You can easily disable this functionality for the user in regedit with the use of a login script running this command:

REG ADD “HKCU\SOFTWARE\Adobe\Acrobat Reader\10.0\Privileged” /v bProtectedMode /t REG_DWORD /d 0 /f

Update Adobe Reader XI
HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\11.0\Privileged
“bProtectedMode”=dword:00000000
