Listed below are steps that can be performed to resynchronize the Backup Exec for Windows Servers System Logon/Service account and installation, to potentially return it to the state it was in when the software was initially installed.
1. Browse to the C:\WINDOWS\Installer Folder. Search for the file "BeInstParams.prm". Rename this file to BeInstParams.bak.
Note: If the Windows Installer Folder is not visible, change the folder options to make it visible (Tools, Folder Options, View: select "Show hidden files and folders" and deselect "Hide protected Operating System Files").
2. In the Backup Exec Interface, go to Network, Logon Accounts. Document which account (User name) is listed as the System Logon Account. If there is not a System Logon Account showing under "Account Name", create one by clicking the System Account Button.
3. Confirm the account listed in step 1 has full administrative rights on the local machine and/or domain and is only a member of the administrative groups. Make sure the account also has the rights listed in the following document:
Requirements for the Backup Exec Service Account (BESA)
Logoff and back on to the media server with this user name and password.
4. Go back to Network, Logon Accounts. Highlight the System Logon Account and then click the Edit Button. Click "Change password" and enter the password that was used to log back on to the machine with. Click OK.
5. Launch the Windows Services Applet. Set all of the Backup Exec Services to "Log on as" the Local System Account.
6. In the Backup Exec Interface, click the Tools drop down menu and select "Backup Exec Services". Click the Services credentials button. Click "Change service account information" enter the credentials/password which matches that of the System Logon Account, then click OK. Restart all the services.
7. Launch the Windows Control Panel, Add/Remove Programs Applet. Highlight "Symantec Backup Exec for Windows Servers", then click the Change Button. Click Next. Select the Repair Option, click Next and allow the repair operation to complete. If it does complete successfully, reboot the media server.
Note: Any patches or updates to Backup Exec that were already applied prior to the repair will not have to be re-applied, with the exception of the Symantec tape device driver update. This driver update will also need to be applied manually and can be obtained via the following link:
8. Log back on to the machine as the Backup Exec Service/System Logon Account. If a driver update, any new patches or an upgrade of Backup Exec need to be applied, stop all non-Native Windows Services and applications that do not pertain to Backup Exec prior to running the update(s). Another reboot may be required afterward.
Note: Symantec recommends that prior to performing an upgrade, all obsolete jobs, selection lists, policies, job history, media sets, logon accounts, etc... be removed first. Symantec also recommends opening a case with Symantec Technical Support, rather than uninstalling and reinstalling Backup Exec if the information above does not resolve an issue, as better solutions may be available.
