We upgraded one of our test servers to DLP 9.1 and after that the existing content rules stopped working. Wondering anybody had similar issues? I had seen similar issue before when we imported the policy that was created on a different server, at that time enabling the file tracking seem to have fixed the problem.
I have done the following checks already.
1. Checked respective agent handlers are enabled
2. File Tracking is enabled
3. Did a screen by screen check of all the settings from another server that has the same exact policy that works fine.
BTW, our policy has some device control rules which are still working fine. It is just the content protection rules that don't work.
Any help or pointers to debug this would be greatly appreciated.
