Cannot Access File Share

User generated image
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.

I have tried the share like this.

\\192.168.1.31\Sharename. its working.

if I run it like \\192.168.1.31 will not working.

I think \\192.168.1.31\IP$ not working

any idea ?
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$

on the server in a command prompt type "net share" this will tell you the available shares.

I think its rpc problem there may be MTU problem.

Can we check of its MTU problem ?

i am still working in this problem, is there  any idea ?
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  7678156698  10595591033  Ethernet 2
4294967295                1       4065     114312  Loopback Pseudo-Interface 1
  1500                1          0     198527  VMware Network Adapter VMnet1
  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?
