After upgrade to 2.5.912.0127 user cannot reboot the DPA via Cluster Management page in admin interface.
User's unable to establish a session to target system through DPA.
Test DPA gives the expected output, but reboot DPA shows the following error message:
"Cannot open file \'/pardpa/dpa-configuration-3.xml\' at C:/Perl/site/lib/XML/XPath.pm line 53."
If issue persists then reboot the Primary Appliance, then attempt the reenroll process above on the DPA.
