vCenter tags collection/assignment using PowerCLI tool

Challenge

Failed to execute SOAP command "CInvSvcCreateCategory". Inventory Service was not created.
Can not Create tag with EXCEPTION: CreateCategory failed.
Failed to dispose inventory service proxy EXCEPTION: The remote server returned an error: (401) Unauthorized.

Cause

Veeam ONE uses PowerCLI to collect and assign tags in VMware vCenter 5.x.

Solution

Proceed with these steps to implement an alternative tags collection/assignment method:

1. Check whether the account used to connect vCenter Server and ESX(i) hosts has all the necessary permissions assigned.
2. Install Veeam ONE 9.5 Update 3.
3. Install PowerCLI 6.5 on Veeam ONE server.
4. On the Veeam ONE server:

• Open Windows registry editor snap-in and navigate to the following registry path: HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Reporter Enterprise\
• Create a new registry key or modify the existing one:

5. Restart Veeam ONE services to apply the changes.
