On installing a new server and all the updates the following was found throughout he Application event logs.
The mount operation for the gatherer application has failed because the schema version of the search administration database is less than the minimum backwards compatibility schema version supported for this gatherer application. The database might not have been upgraded.
It appears that one of the updated required some manual intervention. The link below details what you need to do.
On doing this I started getting errors in the System Event log:
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{B15C0E47-C391-45B9-95C8-EB596C853F3A}
and APPID
{35B4B29E-0A6B-4ED7-B0A1-117BF912F497}
to the user BWEB\spsearch SID (S-1-5-21-26759078-436902130-1702569824-1161) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
This turns out to be related to permission for the “Storage Reports Service”.
Change Component Service Owner and Permission
In the DCOM Config dialog box, you noticed that the settings are grayed out. In order to enable those settings, perform the following registry modification.
1.Open Registry Editor by typing “regedit.exe” in Start > Run.
2.Navigate and select the key “[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{35B4B29E-0A6B-4ED7-B0A1-117BF912F497}]”
3.Right click and select Permissions.
4.In the popup windows, click Advanced.
5.In the Advanced Security Settings windows, select Owner tab and change the owner to Administrators. Click OK to close the window.
6.In the Permissions screen, select Administrators and check Full Control. Click OK to close the screen.
7.Close the registry editor.
In order to change the permission settings, perform the following steps.
1.Open Component Service by clicking Start > Administrative Tools > Component Services.
2.Navigate and expand the node Component Services > Computers > My Computer > DCOM Config.
3.Right Click the sub node “35B4B29E-0A6B-4ED7-B0A1-117BF912F497” or “Storage Reports Service” and select “Properties”.
4.On the Properties dialog box, select Security tab.
5.In the Launch and Activation Permissions section in Security tab, select Customize option and click Edit.
6.In the popup window, add the farm admin user account and check Local Launch and Local Activation permissions. The screen should look like this.
All should be well again.
