When you load Service Pack 3 you may receive one of the following two pop-up error messages:
There is not enough space on the disk.
Service Pack Setup Error:
Not enough available hard drive space to run Service Pack Setup.(30 MB required, or 60 MB if also creating an uninstall directory).
Your only option is to click OK. The Service Pack update process willhalt.
The Service Pack executable file (nt4sp3_i.exe) is a self-extracting filethat extracts itself to the TMP environment variable location. By default,this is set to %SystemDrive%\Temp. If the drive containing this path isnear capacity, you will get the Extraction Error as the file is expandingto the temporary directory.
Upon successful extraction, Update.exe is launched and will update theWindows NT directory that is determined by the WINDIR environmentvariable. By default, this is set to %SystemRoot%. If the drive containingthe %SystemRoot% is low on space you will get the Service Pack SetupError.
Either free up approximately 60 megabytes of disk space (53.8 MB expanded)on the system drive or change the environment variable TMP to another drivethat has enough storage space.
To change the environment variable, perform the following steps:
Click the Start button, point to Settings, and click Control Panel.
Double-click the System icon, and then click the Environment tab.
Select TMP from the User Variables list, and then type<newdriveletter>:\Temp in the Value box.
Click OK, restart your computer, and then try to apply the service pack.
