Slow boot up

Hi,

Has anyone expierenced slow boot up times since upgrading to version 9?

When booting up the PC sits at "Applying computer settings"  for up to 4 minutes.  I have checked my DC's and DNS servers. 

I have also logged a case with Sophos technical support who advised me to try the following.

Exclude remote files.

Exclude the following from On access scanning

%windir%\system32\netwin32\netwin32.dll
%windir%\security\templates\policies\gpt00000.dom (hidden file)
%windir%\system32\drivers\fips.sys
%windir%\system32\drivers\srv.sys
%windir%\system32\TxfAux.dll
%windir%\system32\mswsock.dll
%windir%\system32\sp3res.dll
%windir%\system32\rnr20.dll
%windir%\system32\rpcss.dll
%windir%\system32\authz.dll
%windir%\system32\es.dll
%windir%\system32\netman.dll
%windir%\system32\oakley.dll
%windir%\system32\pstorsvc.dll
%windir%\system32\rasadhlp.dll
%windir%\system32\regsvc.dll
%windir%\system32\winipsec.dll

Disable the Auto update service.

None of these have worked.  Additionaly I disabled HIPS.

The only thing that makes a difference is if I disable on access scanning.  The the PC boots up as normal.

Like I said I have logged a case with Tech support and I'm waiting for them to get back to me.

Thanks

Graeme
