Hi all,

 

Unable to access network files (e.g. \\servername\c$) from newly build windows server 2012.

FYI, By IP address of target network server we can access the ping, RDP as well as network files, and if we do 2012 server reboot then this will work for 2-3 days or longer as a week. 

This issue occurred for just for one single server others 700 servers are working as expected.

Guys, please help me for this issue.

And what error do you get?  From a command line when you try and access \\servername\c$ what do you get for an error?

 

net use \\servername\c$

 

do you get access denied and asked for credentials?  Do you have any other sessions open to this machine?  You say you can access not admin shares just fine?

 

Are you sure the shares are there?  They could be recreated on reboot.. So what does net share look like when ran on the server?

 

exmaple

edit:

"but same userID this is not working in one particular windows server 2012."

 

That points to this box you can not access other server from having a session open to the server that does not have the rights to access the admin shares to me - your saying it can access other network shares?  Check what sessions this machine has open.  For example if something mapped to this server as user X, you can then not access server as user Y.

Your OP wasn't clear, sorry.

Maybe someone is messing around with permissions or they are getting reset...

What is the exact error when you try to access the network share?

So that is a really generic error.. what do you get when you do net view \\servername ?

 

Your saying you can access all the other shares on this box, just not C$ from this location?

Same issue for \\servername, or \\Servername\c$ or servername\D$... 

My concern is only that what is the reason that am not able to access network server from one 2012 server????

 

let me clear the scenario, 

 

e.g. I have below servers in my organization. 

 

PC1 = Hostname is SCCMwin2012

PC2 = Hostname is SQLwin2008

PC3 = Hostname is webwin2008

PC4 = Hostname is SCOMwin2012

PC5 = Hostname is DCwin2008

PC6 = Hostname is DHCPwin2008

PC7 = Hostname is Serverwin2008

PC8 = Hostname is server2win2012

 

All above machine in one domain, and can be ping each other, accessing data by using \\servername\**$ (any drive) but but but.

 

from PC1(SCCMwin2012) can not access data of server PC2 (SQLwin2008). (\\servername, \\servername\C$ any share not working here.) if I do reboot SCCMwin2012 server then only able to access SQLwin2008 data from network.

 

pls let me know if in case still any concerns.

\\servername doesn't work....hmmm, active directory?  if so what are your dns servers in ip properties (ipconfig/all)...sounds like  you are trying to resolve by name and you can't, if you can connect via IP address.

So your saying this SCCMwin2012 can not access any other server?  And if you reboot it you can only access the one SQLwin2008 box?

 

how are you checking mtu? 

 

C:\>netsh interface ipv4 show subinterfaces

   MTU  MediaSenseState   Bytes In  Bytes Out  Interface
------  ---------------  ---------  ---------  -------------
4294967295                1          0      23269  Loopback Pseudo-Interface 1
  1500                5          0          0  Wireless Network Connection
  1500                1  347094734   21410209  Local Area Connection
  1500                5          0          0  Local Area Connection* 11
  1400                5          0          0  Local Area Connection* 17
  1500                1   21162628    1569741  vpn

 

This show 1500?

Yes, I checked MYU by using same command as you mentioned. and I sow 1500 MTU from that command output.

 

SCCMwin2012 can access all servers which are listed in my previous post, except  SQLwin2008... I can ping SQLwin2008 from SCCMwin2012 server but can not access the RDP as well as data from SQLwin2008 machine.

Well RDP is completely different -- do you get prompted for access and denied, or get told can not find.. What error do you get when you try and RDP to its IP address.  And your saying other machines can rdp to sqlwin2008 just fine.

Budman,

As per the weekend patching we have rebooted SQLwin2008 server, hence as I told earlier post that after reboot issue getting resolved and now we all are accessing the server resources from our WinSCCM2012 machine.

 

FYI error msg: "Specified network name is no longer available" while accessing network data.. (\\servername\c$) if we do \\10.xx.xx.xx\c$ it's accessible perfectly. 

 

I'll keep you posted once issue re-occur.
