Cannot access admin shares

Question

Hi,

I'm having problem when i try to access admin shares on one server (there is 8 servers in same subnet - other servers working fine).

On that specific server firewall is turned on - i have tried to turn off firewall but no success.

When i try to use server name or IP address ( \servername\c$ or \192.168.1.2\c$) from other servers it does not work, even when i try on local server with that command it does not work, it only works locally when i enter localhost address (\localhost\c$ or \127.0.0.1\c$)

I have checked registry settings "LocalAccountTokenFilterPolicy" - value is "1"

No group policy are affecting network or firewall (also tried to open ports 445 TCP / UDP, tried with firewall switched off) just does not work.

If someone had similar issue can you please provide solution.

Thank you.

Hi tumarin,

>When i try to use server name or IP address ( \servername\c$ or \192.168.1.2\c$) from other servers it does not work.

What exactly error message do you get when you access?

Could you ping the server with ip address and FQDN.

Please make sure disable both AV software and firewall to do a check.

Please check File Sharing and network discovery enabled on the PCs.

After you change the registry value about the UAC remote restrictions, have you reboot the server to do a test?

And have you tried to use remote desktop instead to do a check.

And please also refer to the thread to do a check.

Hi Mary,

What exactly error message do you get when you access?

*"Check the spelling of the name. Otherwise. there might be a problem with your network. Try to indentify and resolve network problems, click Diagnose." *

Diagnose message: "File and print sharing resource (servername) is online but isn't responding to connection attempts" - solution to that -reboot, tried does not work.

Could you ping the server with ip address and FQDN.

Yes, i can ping with both IP address and FQDN

Please make sure disable both AV software and firewall to do a check.

Already tried that, no joy.

Please check File Sharing and network discovery enabled on the PCs.

File sharing and network discovery is turned on.

After you change the registry value about the UAC remote restrictions, have you reboot the server to do a test?

Server was rebooted after registry change

And have you tried to use remote desktop instead to do a check.

Yes, i can RDP to it.

Any other ideas?

All KB articles points to tasks that i have already performed.

Thanks

Hi tumarin,

Please do a test, if you create a general share folder (not the admin share). When you access with unc path (\servername\share) still shows the same results?

According to the error prompt, "File and print sharing resource (servername) is online but isn't responding to connection attempts", it still points to File Sharing service.

There are no less than four Windows services that must be running in order for File and Print Sharing to work correctly and fully:

Computer Browser
Server
TCP/IP NetBIOS Helper
Workstation
File Sharing

Open the Services MMC snap-in (services.msc) and make sure that those for are running and set to Automatic start.

And please also check if there's more information in the event viewer.
