Can't access freenas with Win XP after upgrade
After upgrading to 9.10.2-U2, I can't reach my SMB shares under Win XP; everything is fine under Win 10.

This has been reported in the forums. It may be related to changes in how Samba handles ntlm auth. Some users have reported that settings the global auxiliary parameter
ntlm auth = yesresolves the issue. Which is odd because I believe that is the default setting in samba.
Additionally, some users have reported working around the issue in XP by changing the GPO
Network security: LAN Manager authentication levelto
Send NTLMv2 response only\refuse LM and NTLM
I imagine upgrading to a modern OS also works around the issue. :)

Sorry to spam this a bit. I finally upgraded and realized that you had bumped the samba version to 4.5.5. In Samba 4.5 the default for "ntlm auth" switched to "no"
NTLMv1 authentication disabled by default ----------------------------------------- In order to improve security we have changed the default value for the "ntlm auth" option from "yes" to "no". This may have impact on very old clients which doesn't support NTLMv2 yet. The primary user of NTLMv1 is MSCHAPv2 for VPNs and 802.1x. By default, Samba will only allow NTLMv2 via NTLMSSP now, as we have the following default "lanman auth = no", "ntlm auth = no" and "raw NTLMv2 auth = no
The options for Windows XP users are either to (1) re-enable ntlm or (2) adjust group policy settings to only use ntlmv2.
