NetWorker: Data Unavailable Due to RabbitMQ Issues on Windows Backup Server

• The NetWorker server software is installed on a Microsoft Windows server.
• After a recent upgrade of the NetWorker server, services start; however, nsrwatch and the NetWorker Management Console (NMC) fail to show any backups and manually starting backups fail.
• The NMC alerts window and NMC gstd.raw report:

Linux: /opt/lgtonmc/logs/gstd.raw
Windows: C:\Program Files\EMC NetWorker\Management\GST\logs\gstd.raw

ERROR generated: "Message bus unable to open socket connection to host 'BACKUP-SRV' on port 5672: a socket error occurred" in file "D:/views/nw/19.8/nsrwebui/modules/nsm/gstnsm.c" line #11364

NetWorker: How to use nsr_render_log

• Port 5672 or 5671 is not listening on the NetWorker server:

nsrports -t localhost -p PORT
netstat -ano | findstr PORT

• Ran the command to start the rabbitmq server and this was the output:

1. Open a CMD prompt using Run as administrator.
2. Go to the root of the volume.

cd D:\

3. Run the following command to show objects, including hidden objects.

dir /a

4. If a 'Program' is found, delete or rename the object.
5. Repeat steps 1 - 4 for any other volumes or drive letters.
6. Restart service: 

net stop nsrexecd /y
net start nsrd

net start gstd

7. Reboot the host at the next opportunity.
