If you try to install Microsoft Windows Server 2003 Service Pack 1 (SP1), the Setup program tells you that you have insufficient available disk space. This symptom occurs even though you meet the minimum Setup program requirement of 700 MB of available free drive space.

This issue occurs if your operating system was updated by using an IPAK. Windows Server 2003 SP1 requires a minimum of 700 MB of available drive space. Depending on the components that you need, the IPAK requires more than 700 MB of available drive space. We recommend that you have 1GB of available drive space to upgrade to Windows Server 2003 SP1 build 1247.
Note In some instances, the upgrade may require more than 1GB of free space. However, the Setup program may not accurately report the required space that is available for your installation.
