The Fax Service Manager admin tool in Windows Server 2008 does not properly add custom cover pages to the Common Coverpages folder on the server. Since the files in these folders have unique rights, we asked MS PSS for assistance.
In the Common Coverpages folder, you’ll see the four default fax cover pages. There’s also another folder inside, EN-US. The same four cover pages are in that folder as well. In order to add a coverpage and have it available to all users across the network using the shared fax service, we found the custom cover page has to be in both folders with the following permissions:
Administrators – read, execute
System – read, execute
Users – read, execute
TrustedInstaller – full control (cmd line - icacls coverpage01.cov /grant "NT SERVICE\TrustedInstaller:(F)")
