Defect or Enhancement Number:

Cause:

Resolution or Workaround:

- Connect via RDP to one of the application nodes and open CMD as Administrator.

- Take a full manual  MongoDB dump: 

<Drive_Letter>:\xampp\mongodb\bin\mongodump.exe --host "rs0/fcn4,fcn2,fcn3" --username dbuser --password filecloud321 --authenticationDatabase admin --gzip --out <Drive_Letter>:\allDBs

- Connect via RDP to the MongoDB nodes, but one by one and starting with the secondaries.

- Open CMD as Administrator and run the following commands:

cd <Drive_Letter>:\cloudupdatetool
cloudupdate.exe /noMongoDump
Select the XAMPP folder location, then click Start.

Notes:

Remove username, password and authenticationDatabase options if you're not using MongoDB authentication.
