Cannot enable File History service: The parameter is incorrect
Sophia Terry 
I'm trying to enable File History on my desktop computer every time I try to turn it on, I get the following error:
Could not enable File History: The parameter is incorrect.For the life of me, I cannot figure out what the problem is. I've looked at EventVwr and found zero logs under:
%SystemRoot%\System32\Winevt\Logs\Microsoft-Windows-FileHistory-Engine%4BackupLog.evtx%SystemRoot%\System32\Winevt\Logs\Microsoft-Windows-FileHistory-Core%4WHC.evtx
I also looked under the following logs and nothing seemed related to the error, near as I could tell:
%SystemRoot%\System32\Winevt\Logs\Application.evtx%SystemRoot%\System32\Winevt\Logs\System.evtx
I've already ensured that both the File History Service and Windows Search services are both enabled.
What are my next steps to try to track this error down?

I used ProcessMonitor and ProcessExplorer to track down the process behind the dialog: explorer.exe. Using ProcessMonitor, I found a INVALID_PARAMTER error:
In addition, I tried doing a regular Backup and found errors that led me to believe that an old Windows Home Server might be causing issues. I removed the home server shares from my libraries (and other user accounts on the computer), but still File History won't enable.
