Cannot Access File Share

RPC-Error.jpg
Hi all,

When we access file share between one server i get this error. There is Sonicwall firewall between two sites, we allowed the any to any between both servers.

Any idea ?

there must be a two way trust if they are different domains. i.e. nyc.example.com lv.example.com

Nope. This is same domain.

Try running this command first &  then try accessing the shared folder.

net use \\192.168.1.31\sharedfoldername  /user:domain\user id & hit enter. It will ask for the password of mentioned user.

If above works then try accessing the UNC path.

if you want the c: directory \\192.168.1.31\c$
 \\192.168.1.31\IP$ isn't a valid share were you thinking instead of \IPCS$

I highly doubt that it is a MTU problem

ping example.com -f -l xxxx
-l = lower case letter L
xxxx packet size

The normal MTU is 1500

By trial and error I see that the optimum mtu is 1472
To find out what my configured MTU is .. from an elevated command prompt
C:\WINDOWS\system32>netsh interface ipv4 show subinterfaces

   MTU  MediaSenseState   Bytes In  Bytes Out  Interface

  1500                1          0     200471  VMware Network Adapter VMnet8

Open in new window

To set the mtu
C:\WINDOWS\system32>netsh interface ipv4 set subinterface "Ethernet 2" mtu=1472
store=persistent
Ok.

You said access via \\192.168.1.31\Sharename works.
Does \\192.168.1.31\c$ also work?
