Microsoft has released a guide to helping the new admin with building sequences with Microsoft SoftGrid. Some of the interesting ones I noticed are...

Sequence to a unique 8.3 directory name. This applies to the Asset directory and to the Installation directory.

Sequence to a folder in the root of the drive. Do not sequence to a subfolder.

If an application requests a valid restart, click Stop Monitoring to enable SoftGrid Sequencer to process the restart tasks. After the restart tasks are complete, click Stop Monitoring, and then click Install Again to continue to install the application if you have to. If the application installer prompts you to restart, click Yes. Many applications unnecessarily request a restart.

Sequence as much as you can in a single pass of the Install Phase. Do not click Stop Monitoring after each installer unless the application has to be restarted. You do not have to click Continue Monitoring to reenter the Install Phase unless a restart task is required.

Click Stop Installation only if you have to. SoftGrid Sequencer monitors the application installation by using a background process. It monitors the first process, the Setup.exe process or the Install.exe process, and any child processes that the installation starts. SoftGrid Sequencer also monitors certain services, such as Windows Installer, that may be involved in the installation of the application. When the installation is complete, sometimes SoftGrid Sequencer will not detect the application because the installation did not end all the child processes. When this occurs, click Stop Installation to stop the monitoring process.
