Workaround to dump NetWorker database using nsrmmdbasm in NW 8.x

In NetWorker 8.x, due to permission issue, we cannot dump the database out using nsrmmdbasm (assume both nsrexecd and nsrd are run as local system).  To workaround the issue after discuss with support.  There are two workarounds.

1. Start the Networker Remote Exec service and the Backup and Remote Exec service using the same administrator account you are logged into the system.

2. Use the “at” windows command to run nsrmmdbasm under the SYSTEM account.

I choose option 2.  First download a copy of PSexec from Sysinternals and unzip it to a folder. 
Then open Command Prompt as Administrator. 

cd to the folder with PSexec tools. 

Run the following command in command prompt
PSEXEC -i -s -d CMD
This will open up a new command window

Run "whoami /user" to confirm the new command window is run as local system.

Then run the nsrmmdbasm to dump the mm out as a flat file. 
nsrmmdbasm -s "C:\Program Files\EMC NetWorker\nsr\mm\mmvolume6" > mmdb.dump
