Maybe that is not a general issue but take place from time to time with different machine types or even different OS script installations. If the OS script would be started a second time it works. At the end of the script if Aclient has been installed and wand to verify data with the DS the whole task fails with the error:
Error 5 during script creation: p:\Altiris\Express\Deployment Server\Temp\5000001.bat
1.Check if an Anti-Virus application could cause a delay on the DS Server or the client. Check the log of this Anti-Virus application if communication has been blocked or questioned. Exclude the communication channel the Aclient is using for the Anti-Virus application.
2.Check the same for any involved Firewall (Client or Server)
