Any impact on SCOM 2012 R2 operation after disabling SMB1

Hi Team,
We are running SCOM 2012 R2 on Windows Server 2012 R2 and we have to disable SMB1 as it is vulnerable, so would like to know if there could be any impact after disabling it?

Thanks.

@Anchalgupta-2608, Based on my research, there are far fewer cases left in modern enterprises where SMB1 is the only option. Some legit reasons:
1. You’re still running XP or WS2003 under a custom support agreement.
2. You have old management software that demands admins browse via the so-called ‘network' aka 'network neighborhood’ master browser list.
3. You run old multi-function printers with old firmware in order to “scan to share”.

For SCOM, after researching, I didn't find any article mention the impact.

To double confirm, we can capture network trace on SCOM server or enable auditing mentioned in the following link: to check

Hope it can help.
