How can i force a Win9x workstation to save all settings before restartingt ??
Restarting, meaning I force the workstation to restart from a run key in HKLM, after the setting are changed!
I am changing the IP settings on all my net clients. BUT - on some of the Win9x systems, the changes i make to the registry are not saved.
I have a suspition that this is caused by users with no patiance (If the computer says restarting, and it dosn’t restart within 10 seconds, they cut the power).
In the ’good old days – Win 3.x’ ![[Wink]](images/icons/wink.gif) , you could force diskwrites using smartdrv /d
If this is not build into Win9x, I would appreciate any hints to programing this in VB or using COM

ps.
I just skimmed the NT4 resource kit for other posiblities.

Some more info:
The script that change the IP settings is run after logon from a run key in HKLM
It only operates on values in HKLM
Jens,
Writes to the registry is immediated: Yes, but i belive that my problems comes from all diskbufferes are not written to disk before ore during shutdown.
Les,
DHCP is not an option, because i’m actually changing the IP settings on the clients to use DHCP, they have been using fixed adresses until now.
(What came first the hen or the egg )
I have tryed to pause the script for 30 seconds. I even tried shelling out to import a dummy .reg file
using regedit before doing the restart
Jack,
Same restart procedure, and same script on all clients. You are surely right in something is wrong on the setup on the clients. The restart could be the problem, i wil dig into this, it is done by an external program.
I know that all my writes to the registry are lost, because the script starts with reading/writing to a private key/value to decide if it has to be run, if the value exists the script won’t run again, this value is also not saved!
The puzzle is that this only happens on about 1 out of 10 Win9x clients.
My last desparate though is to let the the script make a small install of a program, like the windows installer, even if it is installed before. But why bother the 9 out of 10 clients that works with no problems?
What i would really like to do is to flush all disk buffers before i execute the restart command.

Are you looping through all the transport keys? Could the computer have more than one transport such as RAS? code:
:Loop1
$KeyName = ENUMKEY( "$HKLM\Class\NetTrans\" , $Index )
$RC = @ERROR
$DHCPEnabled=ReadValue("$HKLM\Class\NetTrans\$KeyName","IPAddress")
$Index = $Index + 1
If $RC = 0
If $DHCPEnabled="0.0.0.0" $DHCPEnabled=1
Else $DHCPEnabled=0
Endif
If $DHCPEnabled = 1
; Check DHCP Settings
$ReturnCode = WRITEVALUE( "$HKLM\Class\NetTrans\$KeyName" , "IPAddress" , "0.0.0.0" , "REG_SZ")
$ReturnCode = WRITEVALUE( "$HKLM\Class\NetTrans\$KeyName" , "IPMask" , "0.0.0.0" , "REG_SZ")
$ReturnCode = DELVALUE( "$HKLM\Class\NetTrans\$KeyName" , "DefaultGateway")
Endif
goto Loop1
The code above is very old and may not be completely functional.

The kludgy solution
Since I have found no way to force the registry changes to disk, I do the opposite:
Wait until the key is saved.
code:
WaitHKLM()
; Do the reboot
Return
Function WaitHKLM()
; Wait until HKLM is saved to disk, on Win9x systems
; HKLM is saved to the file %WinDir%\System.dat
$RegistryKey = 'HKLM\Software\MyCompany'
$SysFile = %WinDir% + '\System.dat'
$OldTime = @Date + ' ' + @Time
$Test = '' + ReadValue($RegistryKey,'REG-Test')
If $Test = '1'
$RC = WriteValue($RegistryKey,'REG-Test','0','REG_SZ')
Else
$RC = WriteValue($RegistryKey,'REG-Test','1','REG_SZ')
EndIf
Do
$NewTime = '' + GetFileTime($SysFile)
Sleep 5
Until $NewTime > $OldTime
EndFunction
This can cause a pause of about 1 - 5 minutes. But i can be sure that the registry is saved to disk.
Should take care of the 'fast' users, who hits the power/reset button as soon as they see the 'Shutting down windows' message on the screen.
Jack,
Like you I have given up in finding whitch programs/upgrades causes the reboot process to fail.
But my experiance from this, is that some of my users are to impatiente.
