Windows 2008 Server Cannot Ping Clients

Hi I have installed windows 2008 Server Ent 64 Bit on the server

I am facing a problem in pinging the client from the server. All the clients are ping server by

IP, Server Name & FQDN.

I have disbaled the firewall in Server and Clients

When i am trying to Join the Windows 7 Computer to the domain it gives me error message DOMAIN NAME not found. During this time i can reach the server by IP, Name and FQDN. I have tried restarting the DNS Server several times. After few attempts it allows me to Join to the DOMAIN

Where am i going wrong? What might be the issue

Understand that the domain is trying to be connected to NOT the server, might happen cause you're local NIC might have DNS Server not listed correctly OR might have you're router/ISP/external DNS listed on it.

So, perform the following look ups

Ping domain.com and verify results.

on the server run dcdiag /test:dns

does nslookup resolve to IP?

Usually when you get this error its because your Windows 7 PCs are not on the same IP address scheme as your server and/or because the primary or secondary DNS on the Win7 is not your Servers IP address. So check to see what your Win7 IP address and primary nd secondary DNS servers. You can do this by going to
Control Panel\All Control Panel Items\Network and Sharing Center
Then local area network (LAN) and properties.

Hi Sorry for the delayed response, Actually this is the firewall issue. My bad i did not checked the firewall status in the client PC after joining to the domain.

Now another issue i am getting is both sides pinging is fine with IP and NAME. How ever when i am trying to open the server through network it says

Network path not found
Error Code: 0x80070035

This is not happening always, once in while its happening, when i try after few seconds i can browse again, what might be the issue?

My best bet - AV or firewall.

Turn them both off, reboot the box - and check if this works.

Try opening the server using //IP Address OR //NETBIOS OR //FQDN OR //Domain.com

thanks Exchange_Geek, i will check that. But noticed onething i can ping the domain name from the clients

ping domain.local does not give any reply

but i can ping with IP, Server Name and FQDN

Exchange_GeekCommented:
Ping domain.local should also respond. However, as i mentioned windows / third party firewall services - application - AV normally cause such idiocy for us.

Hi if it is the firewall or Av issue then FQDN, Server Name and By IP Address also i should not be able to ping right? But i can ping all those, i just cannot ping domain.local

You're mixing stuff up, you're trying to find answers to ping and network share

My response was for network share

Network path not found
Error Code: 0x80070035

Sorry Exchange_Geek, in your previous post you advised

Try opening the server using //IP Address OR //NETBIOS OR //FQDN OR //Domain.com

I can open the shares with all except domain.com




Network path not found
Error Code: 0x80070035

This error i am not getting always, just sometimes i am getting it

Which box does your local NIC of those client machines point to for DNS Query?

Can you post ipconfig /all for those Win7 machines which are affected? Also, hope that you're DNS / DC boxes are not pointing to external DNS Servers for query on their NIC.

This issue is on all the clients. Ping is proper from all the clients to the server. But suddenly mapped folder is loosing the connectivity and returns after few minutes. From yesterday its happening very frequently.

Thanks

Hi Exchange_Geek

Thanks for your help, I have sorted this issue by making the below changes in the registry of all Windows 7 Clients

Set the following registry key to ‘1':
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
 
Set the following registry key to ‘3':
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServe r\Parameters\Size

Reference:

After making the above changes, Rebooted the computers. Since then Mapped Drives never disconnected.

Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly.  Set the following registry key to ’1':

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

and set the following registry key to ’3':

HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

After making these changes and restarting, I haven’t seen this issue arise again.  Fixed!
