Have you ever tried to encrypt a file located on a file server? Unless you have enabled that server for delegation, you will not be successful (the error below is what I got when I tried):
------------------------------------------------------
Error Applying Attributes
An error occurred applying attributes to the following file:
K:\filename.xxx
The requested operation requires delegation to be enabled on the machine.
------------------------------------------------------
I found some information on this and was able to get it working. What you need to do is to delegate the file server:
An excerpt from a Microsoft How-to Article:
To enable a remote server for file encryption
- Open Active Directory Users and Computers.
- Locate the remote server name, right-click the remote server name, and then click Properties.
- Click the Delegation tab.
- Select the Trust this computer for delegation to any service (Kerberos only) option.
------------------------------------------------------
I had to log off and back on again to make this change take effect, but I was able to encrypt a remote file after that.
