We recently changed which server we pushed Symantec AV updates from.
In theory, all we had to do was move the clients to the appropriate server within the Symantec System Console. This worked for about half our computers.
On the remaining clients, we uninstalled and reinstalled the SAV client application. This successfully attached half of the remaining clients.
For the other clients, the installation failed with the following message: "InstallShield Wizard Completed - The wizard was interrupted before Symantec AntiVirus could be completely installed. Your system has not been modified. To complete installation at another time, please run setup again."
We ran the Norton Removal Tool, checked registry permissions, etc., all to no avail.
The version of Symantec AntiVirus in question is SAV 10 Corporate. The server is running Windows Server 2003 SP2. The clients are running Windows XP Pro SP2.
