[cifs-protocol] MS-SWM Q11 - wondering if ServerGlobalName is really a single name, as I can use a dns or netbios name of the server - TrackingID#2401050040010121

[Jeff McCashland (He/him)]

Hi Stefan,

I've been able to determine that clusters can have many names and/or aliases that can be used more or less interchangeably.

Here is an article on aliasing (a little dated but still relevant):
How to Configure an Alias for a Clustered SMB Share with Windows Server 2012 - Microsoft Community Hub<https://techcommunity.microsoft.com/t5/failover-clustering/how-to-configure-an-alias-for-a-clustered-smb-share-with-windows/ba-p/371737>

Let me know if this does not answer your question.

Hi Kristian,

> With regard to your 11th question (quoted below), I've done code research and the server only compares against one ServerGlobalName, but it does strip the domain of the client-provided cluster netname when making the comparison to the value present on the server. This would make sense why you are able to pass a netname with or without FQDN from the client and get the same result.

Ok, it would be good to have this documented.

But it's not possible to have multiple "virtual" clusters or aliases in a Windows cluster?

The answer is not very urgent...

Thanks!
