By default, Symantec Mail Security for Microsoft Exchange (SMSMSE) version 7.5.5 and earlier utilizes the native Windows FTP.exe client to perform Active FTP connections to ftp.symantec.com in order to download Rapid Release Packages. After installing the attached hotfix, SMSMSE will utilize the HyperText Transfer Protocol (HTTP) instead.
Considerations prior to deploying hotfix
Symantec Mail Security for Microsoft Exchange (SMSMSE) versions prior to 7.5.2 did not have the capability of utilizing Rapid Release v5 packages. If you are currently utilizing a version prior to 7.5.2 see the following KB article before continuing.
Symantec Mail Security for Microsoft Exchange 7.5.1 and earlier will no longer be able to utilize version 4 (v4) Rapid Release (RR) or Intelligent Updater (IU) definition packages after April 15th, 2016.
There are two methods to apply the hotfix, either automatically using a script, or manually.
To automatically deploy the hotfix
ApplyHF.ps1 will create a backup directory called SMSBackup* in the same directory the script was run from. To revert the changes manually copy the file RapidRelease.bat to <Install Path>\SMSMSE\<Version>\Server.
To deploy the hotfix manually
After completing these steps SMSMSE will use HTTP to download RapidRelease updates instead of FTP. No service or server restarts are required.
