Unable to Map admin shares by UNC, but ok from IP address

Question

Wednesday, January 3, 2018 4:50 PM

Hi, I am trying to use Ninite to deploy software to our estate.

Currently we are windows 7, 10 pro, and 10 enterprise.

The 7 and 10 pro I can deploy to. But the 10 Enterprise I can't. I have tried looking at mapping the c$ drives. and it won't allow it by unc path or fqdn, but does by IP address.  I have looked at various things, from regional settings and time, to removing it from the domain gpo, and adding registry entry  LocalAccountTokenFilterPolicy. Also looked at managing credentials.

And Nothing is resolving this. 

Any advice/help would be gratefully received.

I have just found another thread with the same issue - seems to impact build 1703. 

Please change  GPO: **Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft network server: Server SPN target name validation level **to Off.

We have set a gpo test up, and are awaiting replication before forcing the update and testing again.

Hi Christine,

Can you ping Windows 10 Enterprise via hostname or FQDN?

It seems like your DNS or WINS have problem.

Please check if the DNS and WINS settings configure correct on these Windows 10 Enterprise.

Use nslookup command to see if the Windows 10 Enterprise can resolve the FQDN to IP.

After that, run the following command as Admin to flush the cache:

IPCONFIG /flushdns

nbtstat -RR

After that. confirm if the issue has gone.

Hi, yes I can ping the win10 ent machine by hostname, and nslookup resolves too. I can also remote desktop to the machine using the hostname - it seems to be just mapping. and thus using Ninite to deploy, which is the problem.

Hi Christine,

For third-party product Ninite. I am not familiar with it.

Let's only focus on the Map issue on this thread.

Could you please share the exact error screen here for analysis?

And what if you type the UNC path via RUN box?

Alternatively, you could use net use command to map the network drive.

From Win 10 pro machine mapping to win 10 ent using explorer, I get a logon box, put in my credentials, and it gives me access denied. Using IP address it goes straight in. I've even tried using the local admin account and it's the same. 

From the run command - I get a box saying that there is a problem accessing the machine, and then a you do not have permissions to access the c$, which you don't get when you use the ip address - it goes straight in. 

Under net use you get asked for username and password and get a system error 5 has occurred and Access is denied. If you use the ip address again it's ok.

Not yet, sadly.

I've got to get approval to change the gpo. But we can close this, as I believe this is the issue. If it turns out to not be then I will dig further.

Thanks
